IIRC, the OP said the foot-pedal sends only 0 and 127... that's why I suggested a boolean-like enum. Are there hi-hat controllers that send 128 steps? >> * When Hydrogen gets a MIDI Note On for Notes >> 42 (Closed Hi-Hat), or 46 (Open Hi-Hat), it >> needs to re-direct them both based on the >> current value of pedal_state.

I'm not sure what other sampler/synths are doing. To get similar sort of behavior from Hydrogen, you would probably need to implement sort of a 2D-layered instrument (select sample based on velocity and a 0.0-1.0 controller value). The controller value can be mapped to anything (like CC#4). Currently Hydrogen only has 1D-layered instruments (select sample based on velocity). -gabriel ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
