Hardware and ActionMatchers

[Kirkwood West]

Working on building some action matchers for the xtouch mini but i'm not sure how to go about doing it.

Code: Select all

 hardware_button = hardware_surface.createHardwareButton("XTOUCH1_BTN");
 HardwareActionMatcher          pressedButtonAction = midi_in.createNoteOnActionMatcher(0, 87);
 HardwareActionMatcher          releasedButtonAction = midi_in.createNoteOffActionMatcher(0, 87);

The problem i'm trying to solve is that the midi events are BOTH Note ON. Note On at 127 velocity for press... and Note On 0 for release. So I'm not sure how to create a different noteOffAction Matcher.

I dug through the API help but could not find much there, thought maybe this... but have no idea what to supply as an expression...

Code: Select all

HardwareActionMatcher createActionMatcher (String expression)	

And then I look at velocity options with note on but it is not a Hardware Action Matcher, seems like you would use this to attach note velocity to a knob or something like this.

Code: Select all

AbsoluteHardwareValueMatcher createNoteOnVelocityValueMatcher	(int channel, int note )

ugh... got lost on this one. Any help would be appreciated! Thanks

Looks like actually my debug code was busted and the notes are properly detected anyways. I just had the same debug spew coming from both pressed and released functions. Classy!

However I did learn how to use the String expression in the process for ActionMatchers. I think this is pretty useful since its not described in the API help.

HardwareActionMatcher releasedButtonAction = midi_in.createActionMatcher("status == " + Midi.NOTE_ON + " && data1 == " + 87 + " && data2 > 64");
