In the instrument editor, I'd like :
1) a horizontal
Sample Map with a scrollbar
(like the order view in the pattern editor).
It would be really easier to work with I think (since keys are horizontal on a keyboard), and the number of displayed notes could adapt to the window's width (like the order view).
2) a value box
for each slider (Reso, Cutoff, Random Variations), exactly like the Ramping slider already has (since iIt's hard to have enough precision with a slider).
