thank you very much Devo, it's good to have the slide function in fl studio. but it seems like i got stuck in a few more issues about piano roll for fpc. first, is it possible to change the tempo within the pattern? 1st beat to 4th beat 75 bpm and 5th beat to 8th beat 90 bpm for example? and second, i'm writing drum lines using piano roll. but instruments in fpc are in a complex order. for example, bottom to high, kick, ride, E4, floor tom, F#4, hi-hat, ...(bunch of notes)..., splash, B5, C5, snare, etc. can i get them in order some way so that they goes on like kick, snare, hi-hat, crash, tom, etc.?
