Frap Tools USTA Review and Tutorial

USTA is a eurorack sequencer based around the concept of four independent tracks with variable stage lengths, meaning that each step in a sequence doesn’t necessarily represent the same amount of time as the one before or after it.

It also supports chance and randomization or a per stage basis and has 16 stage knobs for immediate access stage parameters. It’s quite a bit more powerful than may initially seem, but with power comes complexity. Here’s a full review and tutorial alongside a walk through what a set up it controls can look like:
