You have slides, octave up/down, notes, and timing controls. The slides are probably the most unique part of the sequencer on paper.
You have patterns and variations you can switch between and tracks that let you string patterns together.
The part that I think (IMO) makes it special is the horrible way you have to enter notes. You have to do it while the sequencer is stopped. You enter in a string of notes with/without slides etc (like silent step mode), then press play to see if you like it. Then you have to stop again to make edits. You can step through the notes manually while making edits though.
I think this leads to things you wouldnât maybe do while itâs running.
Itâs probably the slides in most peoples eyes.
I do think that having to stop and think about what youâre entering makes a difference too though.
