Ganz Graf is very nice - kudos to the designer and to Synnack for the mod. It is definitely a step in the right direction for creating realtime visual output that responds to audio - beyond the relatively dull VJ clip playing stuff. It would be great to find a way to mix other inputs into something like ganz graf....
As far as I can tell, if it was easy to insert jit.qt.record to record ganz graf output, someone would have done it by now. I haven't figured it out yet, being a M4L noob.
Vizzable devices do not seem to work alongside ganz graf because the vizzable units are used on midi tracks and ganz graf appears to be a unique object that works on audio tracks - usually the Master track.
I have tried some screen recorders (windoze) and they ALL seem to render low quality video even with a good gpu with sufficient RAM.
