Here’s some background about this site and its companion YouTube channel.

What drove me to open this site and channel is my deep appreciation for others sharing their knowledge online, and the need to reciprocate in kind. I do enjoy digging deep into what a piece of electronic music gear can do – and learning by having someone show you is the best way to do that, especially considering cryptic manuals some manufacturers create.

It almost goes without saying that aside from having someone teach you in person, YouTube is the best place to quickly find fantastic electronic music making tutorials and gear overviews.

Anyway, every now and then I discovered something that wasn’t documented or obvious – whether it was a workflow idea, or a “trick” that I felt a lot of people were struggling with (or at least I was), that has a simple but non obvious workaround. The urge to share this information is what drove the first uploads to my channel.

So, that’s how it started, but uploading into a vacuum wouldn’t have lasted long. Luckily, it’s been anything but that. The feedback and encouragement from people like you reading this, has been the ultimate motivator to keep doing this. This book is my way of saying thanks for being a part of this journey.

So what’s Loopop? Well, most electronic music gear supports some form of looping or sequencing, and if you want to know how the LOOP OPerates… or if a LOOPing idea POPs in your head, or if you take a LOOP and turn it into a POP song… well, hopefully LOOPOP will help just a bit 🙂

  1. Thanks a lot for your fantastic reviews and tutorials! Complete and to the point ! i always look to your reviews before i buy synths. My question for you. I have a Elektron Octatrack MKI. i like the sound and i see a lot of people making fantastic things on it but i don’t use it a lot because i can’t get out the PART management! I have a digitakt and it’s great and i can work with it because you have patterns. The octatrack has pattern parts in a bank and i don’t understand the point of this and how i must use it. Is it possible to make a good tutorial around this theme? I think a lot of people would appreciate such tutorial.
    I want to thank you for reading my mail and hopefully you can help me with a great tutorial around part patterns and banks on the Octatrack!

    Thanks a lot
    Melanie & Wouter

    1. Hi Melanie & Wouter,

      Thanks for the kind words! I haven’t gotten to the octatrack yet but it’s certainly on my to do list… I will try and find time for it!

  2. Which video? You don’t need an app to make samples longer you should sample them at double speed and play them at half speed. You can use the free app Audacity on a computer if that’s what you mean

  3. Hi,

    I responded to your video on the Behringer model D. I wanted to record my experiences in a video. Until now I used Hypercam for screen capture, which sometimes failed because it didn’t record sound (a common complaint). My guess is the configuration with a MIDI controller, hard-and software synths a webcam and a external sound card is too much for poor Hypercam. Looking for an alternative (preferably free, since I won’t use it a lot and even fear I won’t succeed recording this comparison between the model D and a VST, or even my model D and yours, using the video on YT), I noticed the reviews are written with other uses in mind (predominantly games or recording from youtube). So my question is what do you use for your recordings? Or do you know a free alternative?

    Thanks in advance.

    1. Do you mean what you can use for screen captures? I use OBS on Windows – it’s free, and so is Quicktime on Mac

      1. Thanks. That’s what I meant, yes. I’m trying to master OBS by now. The problem with hypercam2 turned out to be the ASIO, apparently to be solved by Voicemeeter (and it is).

  4. I was wondering if you have ever done a tutorial on the audio damage sequencer 1? I really enjoyed the one you did on maths I learned more about it in the short video then over a year of owning it.

    1. Hey – just saw this question – No, I’ve never reviewed Sequencer 1. Thanks for the kind words re the Maths video!

  5. Thx for your great reviews
    I would like to know what subject are include in your book, it’s any introduction for a beginner how to start patching your euro rack, what things follow the other in the patch chain?

    1. Hi! Thanks for your interest. I really should make a table of contents available – until then there’s a brief snapshot of it at the end of my videos. I’ll also consider adding a eurorack for beginners chapter to it ASAP!

  6. I would love to hire you to be my private tutor. I am fascinated by your skills intelligence and teaching ability. I have been doing rector and vcv rack for a while. I started eurorack a number of months ago. I am a 69 year old eye doctor who loves to learn. By the way Patreon keeps locking up for me.

  7. hello how do you change semitones in a live performance in the roland mc-707

    I can only change the transposition, in the mc-101 I press the note key and then the note I want on the keyboard and change the semitone

  8. Your youtube posts are such a tremendous help in any way soundwise or technical wise !!!!
    I have en ewi controller question regarding the moog sirin, since i heard the sirin has quite bad midi zippering, would it be able to use for instance a midi to cv converter like the doepfer mcv4 triggering the notes and smooth out the notes using the cv filter from the pedal to the sirin and maybe the pitch as well ?

    1. I guess you could, but I’m not familiar with any zippering. Have you experienced it or just heard it happens?

      1. i heard it happens, in the mean while i tried the microfreak ( because of the nice quality filter), and it has zippering as well in the high end, i would like to try out a midi to cv converter like kenton, in what johan berglund from the nurad ewi adviced me though,was to get one with slew rate but i can’t seem to find any which have this option, and is there a possibility to play the poly d moog polyphonically with cv.?

        and i’m still a big fan of your reviews. !!

  9. Hi. first, I love your videos – the information is on point and I learn a lot! Also, because of your good and deep explanation, I bought a Circuit Mono station. I have a have a question and I hope, you can maybe help me. I can’t synchronize the clock of my MonoStation and the circuit groove box. I was putting the auto clock of in the setup view and trying different variations of master and lave – nothing works – except putting the circuit as Master, Midi into CLOCK IN in the Mono Station – I saw the “SYN” at the grid, but it played totally fast and not in time. I was trying out with different midi cables, different breakout cables.. I contacted the novation support, but they could not help me – I don’t think they care. sadly.. Do you have any Idea?

    1. Thanks for the kind words! Sorry, a lot of people contact me with sync/troubleshooting issues and I just can’t help with setups on an individual basis otherwise there would be no channel… :/

  10. Hi – great site and reviews!

    I came here after looking around for some decent info on an SH-101 (which I found!), but in the video (the one where you compare it to a Behringer MS-101), you seem to have a couple of large screens showing the waveforms created by each.

    Can you tell me what these are? – how they hook up? – where d’ya get ’em?? . . . look so cool, and useful too 😉

    Thanks in advance!

    1. Thanks! Sorry, the screens are fake – don’t I wish they were real! I overlay scopes by Melda on the video in post production

  11. Hi,
    Love your videos! A real inspiration to me.
    Is is possible to buy your ‘In-complete book of electronic music ideas tips and tricks’ without a Patreon membership ?

    1. Thanks very much! Unfortunately, that’s currently the only way for me to make sure you get the most updated version.

  12. hi!
    thanks for your fantastic reviews?
    i have a question: I bought a behringer odyssey and poly D
    they are both great, but I don’t seem to be able to clock them to my Logic Pro x system
    I already tried via midi and the doepfer MSY2
    someone mentioned the sysex system to do that, but that seems way too complicated
    do you have any idea, cause I wanted to use both sequencers in time with my logic… 🙁
    thank you so much!!
    nico jacobs

    1. Thanks! And sorry, I get many set up questions … if I’d start troubleshooting them all there would be no channel – I hope you understand…

  13. Just want to say how much I love your reviews and would love to know what your favorite resources on electrical music synthesis are. My wife and I just love watching your videos.

    1. Thanks so much for your comment, I really appreciate it! There’s no one resource – I do however read and watch whatever I think can learn from – there’s so much out there to explore and each person has at least one nugget of wisdom to share 🙂

  14. Hey man, love the videos! I was just curious as to what digital oscilloscope and spectrum analyzer you used. They way you crop them into your videos is a very nice touch.

  15. Hello Loopop,

    I’m a long-time fan of your work, as well as a devoted lover of all things synthesis and groovebox-based. My question for you is: how do you find time to be so dedicated and prolific? I feel this is a common problem for many people, and I’m so keen to know how to be better at this. I have all the gear I could have ever dreamed of, and my own dedicated studio, finally, after years of working and saving. But often now I’m just tired and reluctant to explore.

    Would you consider creating a video for YouTube explaining your creative process? How do you make time to be in your studio, in addition to curating so much content for your viewers? I’m sure you are quite busy with your jobs and your private life, in addition to all of this. I wish to learn how to be better at using my time and energy to synthesise, like you seem to do. The thing I love most about the synth community is their genuine desire to share and support their peers, in addition to their complete lack of ego, so I thought I’d ask these questions plainly and directly in hope of your response.



    1. Hi David,

      Thanks for the kind words. I guess your question is two fold – first, my process – I actually wrote a whole chapter (well, a few pages) about that in my book and may one day produce a video about it.

      But, I guess the more important question is my motivation, and that I think has less to do with synthesis techniques and more with psychology.

      I too am tired when I’m uninspired and find endless energy when I have something motivating me, regardless if it’s synthesis or anything else.

      I’d need much more self introspection to explain it, but if I had to sum it up now I’d say that you need to find the thing which will drive you so much that you can’t rest until you complete it.

      A tune I must play. A show I must do. A trick I must share. A synth I must cover.

      “Must” being not because someone is forcing me or paying me, but rather I must because I cannot not do it.

      Hope this helps!

      Ziv / Loopop

      1. Ziv,

        That’s a wonderful way to express it. I must synthesise because I cannot not. I understand! 🙂


  16. Hey Ziv,

    Any chance you’d consider selling a printed version of your book? Feels like it deserves a spot on my shelf. There’s all kinds of self publishing sites out there, so it shouldn’t be too hard, and I’m sure I wouldn’t be the only one buying it!


    1. Thanks very much for asking. I’d love to see that on my shelf too, but I feel like I have too much to add, if I “froze” it in time I’d be selling a half baked, in-complete product… plus really the point of the subscription is to fund the continued search for ever more synthesis knowledge

  17. Hi Loopop,

    I have serious GAS for the Sequential Prophet 5/10 at the moment, but don’t have the option of testing one for myself.
    Are you planning to review one anytime soon?

    Thanks & keep up the great work!

    1. Thanks! No plans – I had GAS for it too, hopefully it will pass for you as well… I think at the price there are better alternatives but I don’t have a sentimental attachment to the 5… if you do, it may be a problem

      1. Thanks for responding. It’s a shame you’re not planning a review, yours really are some of the best and most thorough reviews out there.
        No particular sentimental attachment for me.
        I am wanting, if not needing, an analog poly with a distinctive sound (a “presence”), a quality feel to it, including keyboard feel, and an immediate but flexible user interface (I’m not a fan of extensive/overly-complex modulation routings in a poly).
        The Prophet 5/10 appeals visually (I guess there may be some sentiment in that) but I’m still trying to assess how flexible/suitable it is sonically… and, of course, I would prefer if it was more affordable.

        Keep up the good work!

        All the best,

  18. Hi. Love the review and tutorial videos. Their very easy to understand and very comprehensive. Keep up the great work. Could you share what you use for your real-time time domain and frequency domain analysis that I see in so many videos? It’s especially intriguing because there are note names in the frequency domain graphs. Sorry if you’ve answered this question in previous comments/videos.

    1. Thanks! I use MOscilloscope and MAnalyzer by a company called Melda – they’re free with some limitations in the MFreeFXBundle. Occasionaly I’ll use scopes by VCV

  19. Since I found your channel at the beginning of lockdown 1.0 I’ve been hooked, best electronic music gear reviews on the internet.

    I’m intrigued by the piano roll overlay on some videos – the one that shows a keyboard and vertical scrolling note hits (I.e. on the NDLR review). Could you let me know what you use for that? Thank you Loopop!

  20. Hi, great work in general, you are my goto 10 source for reviews 😉

    To that point, I searched here for some content on visualization and metering but did not spot anything. I have a nice little studio but want to dedicate a screen to visualization (metering, oscilloscope, so on). Would you be willing to share any recommendations? Some of this also just stems from missing an awesome/large meter bridge that I lost when I went ITB for recording. I wish someone made a standalone bridge but I have not found anything compelling.

    You’re the best, thanks man! – Jonathan Knorr (@djjknorr on IG)

  21. May I ask what country you live in? I’ve been wondering about that since I’ve been following your channel 🙂

  22. Hiya,
    Loving your videos, thanks so much for those, very helpful! I was wondering, what signal analyzer (oscilloscope) are you using to view wave forms?

    Thanks !


    1. Thanks! I use MOscilloscope and MAnalyzer by a company called Melda – they’re free with some limitations in the MFreeFXBundle. Occasionaly I’ll use scopes by VCV

  23. Hi, Over the weekend I have just released a (Windows) program for generating Single Cycle Waveforms, that I have worked (on/off) for a number of years, and never released, before now. I do follow, and like your videos, so I though perhaps this program would be something of interest to you. If you are interested, it can be downloaded via the link below. The installer comes with a 170 page manual (that can be accessed from within the program), and the web-site contains links to 8 videos showcasing this software (also available via menu-items within the program).

  24. Hi.I am a musician, poet and lyricist specializing in childrens music.Can you steer me to a really good creators platform
    that is simple to use and honest.Thanks!

    1. No sorry – you’ve got to do the research until you find the environment that’s most conducive to your creativity

  25. Hey! I absolutely love your videos. I’m currently on the fence about getting a Matriarch or a Prophet 6 as my first full size synth, and my biggest hold up on the Prophet is that I haven’t seen anyone do a great video on it like you’ve done for many other synths. Any chance you might be getting your hands on a prophet 6 any time soon? Would love to see how you break it down.

    1. Thanks very much! I’d love to spend time with the Prophet 6 but it’s not likely to happen any time soon

  26. Hi Ziv- thanks for your content. In regards to your recent video on Continuum- it is the most informative I’ve seen!- I do have one and have been struggling with the Eagan Matrix. This, having read the manual and watched the videos. I still can’t connect the filter and felt a bit down when you skipped that part. Would you be willing to give me a private class on it- just one hour over skype or zoom would help me tremendously.

    1. Hi Mik,

      Thanks for the kind words! I don’t normally give classes but feel free to email me (email is in every video description) and we’ll set a quick call up – 30 minutes should be enough it’s quite easy.


  27. Hi Loopop,
    unfortunately I don’t know your name.
    I would like to thank you for your incredible dissemination work you are doing, fortunately also recognized by many people and companies who refer to your videos and your skills. Thank you very much.
    I am very sorry that I do not speak English and I cannot read your book and understand your videos, my English depends on Google Translate. Thank you very much.
    I’d like to ask you a question.
    I have an 11 year old son who will start the 4th year of piano in September. In addition to this I would like him to approach the world of electronic music without using PCs and DAWs.
    I bought him 5 sinth Korg Volca, NUTEKT NTS-1, UNO Synth and UNO Drum from IK Multimedia, Skulpt, Arturia KSP and Microfreack to make a small studio for electronic music composition.
    I see your videos and I have seen the ones where you talk about NDLR.
    I searched the web for a lot of information, I would like to buy it but I think it is limiting in creativity because it is very preset and cannot be connected directly to a musical keyboard.
    I wrote an email to Conductive Labs and they confirmed my doubts.

    My question.
    Do you know if there is a “something” like NDLR to be connected to a keyboard and that it has its functions, that is, it has several outputs, which can be configured differently, but which are all correlated with the information (chords and notes) entering?
    I realize that NDLR may be unique.
    I am thinking about Pyramid, I have seen your videos, but the use is a bit complicated and for the moment I would not want my son to stray so far from the keyboard and the music.
    NDLR would have been perfect if ….

    [Here are the answers from Conductive Labs:
    Question 1:
    Is it possible to connect a Midi keyboard to the Midi input of the NDLR, play any chord during the performance and have the 4 lines output: 1 Pad, 2 Motif (2 arpeggio lines) and 1 Drone?
    A: The NDLR is not a typical arpeggiator. Instead of entering the notes on the keyboard, you will pick a key and mode which creates a note pool for all of The NDLR’s parts. You can only select the chords and chord types available based on the selected key and mode, and only the ones offered by The NDLR.
    The polyphonic part on The NDLR is called the PAD part. Its is primarily made for playing pad type synth patches, but not so great as a general purpose chord player. The chords that are available can be selected using the buttons on The NDLR, or you can use a keyboard to select chords.
    Question 2:
    Is it already possible now, or when will it be possible, to play any chord or chord progression with NDRL without external keyboards?
    A: You can play the chords with the buttons on The NDLR, or you can sequence a chord progression with The NDLR Chord Sequencer. I typically sequence chord changes with a Korg SQ-1, but you can do it with any MIDI sequencer. You could also use a MIDI foot pedal too.
    Question 3:
    Are NDLRs now available?
    I am in Europe and I was thinking of buying it through
    A: NDLRs are available now. We sell them on our website,,, Perfect Circuit in USA, and Juno Records in London are all good options for ordering on line.]

    Thank you so much for everything.
    Best regards
    Gianfranco Mancinelli

    1. Thank you for the kind words – sorry that’s a very generic question and I don’t really offer a service where I give 1×1 purchasing advice, so I recommend continued research

  28. You have the best tutorials out there !!!
    Straight to the point , clear and organized !!!

    Every time I want to get new gear , I check your channel to see if you have a tutorial for it … too bad you don’t do any tutorials for bass player LOL 🙂

    Anyway …. Thank you !!! Keep it up

  29. Hi Loopop!

    I’m a new to synths and a new fan to your videos and they’re amazing! I was wondering what oscilloscope (is that the right term?) you use to visualize your wave forms during the videos. I think it would be helpful to have a tool like that as I’m diving into hardware synths and yours is very intuitive to understand, with the wave shapes on the left panel and frequencies & notes on the right panel. Keep up the awesome work!

    A fan you recently sold on the Behringer Pro-1 🙂

    1. Thanks! I use MOscilloscope and MAnalyzer by a company called Melda – they’re free with some limitations in the MFreeFXBundle. Occasionally I’ll use scopes by VCV

  30. Hi there,
    great videos and I have a question about the Korg Modwave video…
    at around 4 mins, you play using a grand/concert piano sound, and I would like to know if this is a preset in the Modwave or some wave samples that were purchased, if so, where are they from please?

    Thank you and kind regards!

  31. I am looking for a hardware synth to integrate with my Maschine MK3 setup, however, I am struggling to come up with a decision and can’t stop going backward and hesitating toward other gear I see.
    I also don’t want to break the bank in purchasing a piece of hardware for something I consider a hobby, which is minimal / jackin house and some techno.

    – My initial choice was the Moog Mavis with an Arturia Keystep combo;
    – The second choice is a combo of cre8audio East Beast and West Pest;
    – The third choice is a second-hand 0-coast by Make Noise;
    – And sometimes I think of the Arturia Microfreak.

    I am unable to decide which device would give me more fun to play with.
    Any tip or advice would help.


  32. Hi Loopop,

    I’ve been following your videos and have already learned a lot from them. Thank you for your work and dedication to this project. I was wondering if you will ever make a VAST tutorial. I know that it is a bit niche in terms of target audience, but with the increasing interest in the incredible K2700 workstation from Kurzweil, maybe it would be an opportunity to check it out. Just an idea.

    Wish you all the best and keep up with this wonderful project.

  33. Hello,

    I was just watching a tutorial and wondered how the ghost screen (the visual on the synth added while editing to show the waveform of the sound) got there? 🙂
    It looks realistic and futuristic
    Here is the link of the video ‘’

    Looking forward for your reply

    Kind regards
