I’ve been using the Torso T1 sequencer recently. Technically it is defaulted to 16 steps and 4 bars, however, the step count can be anything from 1-64 steps per track, with 1-16 bars (called cycles) per, and the clock division can be anything from 1/1 to 1/64 and 1/3 to 1/48. You can change the clock division per step or per bar, and each bar can be any number of steps you’d like.
I guess the only issue I have is with so many possibilities and options, I have a hard time getting out of standard 4/4-feeling stuff, and because everything can be almost anything, there are times where it feels too chaotic.
That said, I’ve had it for a very short amount of time and it’s very powerful.
