I'm not sure i know wut you mean. But if it is wut i think, then it could be them pitch bend or effects wheels. I know you seen them. Theyre on the left of the keys usually.
Im havin trouble loading a pic right now, so heres the link:
it's probably hard to record it, without having an actual external pitch bend...how about drawing it...can't remember how it's done in the sequencer, apart from the fact that it's around the same place where the velocity is shown.
It's hard to tell from your snippet, but it sounds like the bass goes down for the first approx. 1/3 of the bas lenght and then quickly up...
errm da pitch bend aint workin as i thought it wud, its bound by a few notes, it doesnt reach dat high, i hav to draw it in the matrix but the accuracy only goes to 64, i need higher for the effect, cuz i can do it using the mouse to scroll up den down da keys in da matrix
umm, all you have to do is play another key with less velocity, on my moog it has a 'glide' function to automatically pitch bend notes more smoothly into eachother. you can also set the pitchbend wheel to be less responsive in most programs to emulate playing a diff key or switching octave's
