A tick shift/delay option to tracks (in addition to the ms delay already available).
This parameter would silently shift the note data x ticks forwards or backwards when being parsed before generating any sound.
This would be helpful when using sliding instruments. Sometimes you want the slide to start before the row. And I think using the ms track delay would mess with realtime streams and line input, no?
(Renoise generally needs better ways of handling instruments with attack, where you want the strike to be on the line. The pattern interface is bad for this, but features could be added that makes it feasible working with… )
