Velocity tracking for filter cutoff

[martinvicanek]

Most instruments change timbre when struck, blown or generally played harder. This could be simulated by a lowpass filter applied to a sample, with the cutoff increasing with velocity, optionally with additional key tracking. SFZ provides volume tracking with velocity, but apparently not filter cutoff tracking with velocity. But only increasing volume does not sound right.

Thank you for your quick reply, redtide! The opcodes on the linked pages are for modulation by the envelope, that is not quite what I am after. Meanwhile I found the fil_veltrack opcode which does exactly what I was looking for. Don't know why I misses it at first. Thanks for the help, and sorry about the false alarm.

No worries... "so many opcodes, so little time..." :)
