Getting MIDI Aftertouch data into vvvv

vvvv beta question
2

Hi rozenfranck, if you are talking about releasing finger of the pad, read Key Off signal 's Velocity for the after touch .
If its pushing on the pad, just read the velocity outputted by Midi Key On.

Some hardware have possibility to just toggle their signal, without being pressure sensitiv ( Vel 0 / 127 ). but by default your akai is in Pad mode, pressure sensitiv.

did you check the signal outputed with other softwares ( midi ox, for ex)?

There is MidiShort, i recommand you to use it. you will have data, according to this table:

- define typeNote		0 	/* note with pitch, velocity and duration		*/
