Hello, Finally audio on Linux has convinced me; thanks to my DeMuDi 1.2.0 ! So just for the curious, I've setup a strong soundsystem in order to make some Dub. On Fluxbox I use my 4 desktops : on the first one I have TerminatorX (to simulate tape or vinyl rewinded) it is the audio source that I inject in ams that plays the r?le of pre-amp/crossover it is working quite strongly and it is on the second desktop where I disconstruct the sound for the Dub. On the third desktop I have Qsynth connected to my midi keyboard to play some chords (riddim in dub jargon). On the fourth desktop I have ardour that centralise all the stuff : ams, qsynth and my Roland TB303 which is routed directly by the line in. The output of ardour is routed to the Meterbridge. So in ardour, thats the subject of my post, I have for the moment 4 tracks : Master (stereo) AMS (stereo) TB303 (Stereo/mono ???? I created a mono track) QSynth (stereo) when I look in JackC i see that the 2 capture channel of my sound card are connected to the lonnely TB303 in, but I have two TB303 out !!?? I must say that I have added "stereo" effects on the TB303 track when I play live no problem, but if I want to record, all the other tracks can be recorded but not the TB303. Ardour doesn't allow to record a such "hybrid" setting ? Or this is a logical behavior ? anybody could point me ? thanks Philippe PS : the lonely bad thing about having such setting on linux, is that I must open all the stuff each time I want to access the soundsystem :-( and reconnect client that use a pid number to identify them (like the meterbridge)
