Well... I know I'm quite a boring person, but I need some informations for my project and so I'm going to stress you a bit ;-) I'm wondering if JACK is suitable to transfer non-audio data beetween applications (my particular case is to transfer control data to processing plugins). Is that "naturally" possible, is it an hack or is it impossible at all? And another thing (I'm too lazy to check it out myself :-P): does jack transfers data by copying or uses something like shared memory or whatever? Thanks is advance. Stefano D'Angelo
