I, like many others, started making music with trackers. I used Impulse Tracker, back in '97-'98. For me, monoMED is a time-machine. It travels me back in time, when 2-5MB of samples were enough to finish a bunch of great songs as a nerdy kid in my bedroom on my 386 IBM PC. For you it might be something else. But, it is a tracker style, 16 step MIDI sequencer, with Note, Velocity, Note length, Delay / note and 2 assignable controls. You can change the pattern length and direction, also, you can save and recall patterns.
