I must admit that you lost me there... I am already stumbling over the face that a CC message has two parameters, yet the dialog shows only one (I suppose the first paramter is for the event). Then the action has another parameter... I don't really grok the whole dialog, that situation is not helped by the widget set limiting the preferences window to a certain size, resulting in the fields in the action column being cut short (with ... in the middle) ... ah, one can manually resize the column... OK, but still I have to guess a bit on what the actions mean. But they might be documented someplace, I did not really search for that. > > 2.

I think what I want is just a bit of added magic on line 201: int nInstrument = nNote - 36; depending on some lookup table in MidiInput, that is modified when CC messages come in, or I really just skip the CC part and set the mapping on note on/off of the hihat pedal. As long as there is no real hihat controller with more levels of openness, this mode would be more useful, even. I don't see much difficulty in adding this in the source, perhaps adding config file settings, too ... it might be harder to work this out on the hydrogen GUI. I'm not so experienced with GUI programming. And I must admit, I already preferred direct editing of my drumkit.xml to add additional samples/layers/instruments, instead of using the hydrogen GUI for that... > > Before I rampage on a search engine spree: Do you know such a program that > > I could hook up to trigger hydrogen with modified MIDI events? > > > Hm no, but i think other people can help you here. Maybe you should ask > this question at the Linux audio developers mailing list! I found qmidicontrol so far, from the Alsa Module Synth project... it can remap MIDI events, but I think it would need hacking to support changing its mapping on MIDI messages. Not totally sure, though. I think I'll go down on hydrogen first because it promises fastest result -- when the code is so neatly structured as its appearance suggests (so, nInstrument really is the only thing I have to change). That should be done in some idle hour this weekend... you'll see a patch;-) Alrighty then, Thomas.
