I've been trying to build a patch using jit.vcr. It seems a little buggy, but I may not know what I'm doing. It won't accept a realtime 0 message (it is set to 1 by default). Also, sometimes it records the audio tracks, and sometimes not, and I have been unable to demystify when and why it does. (It usually does not). Have others been using jit.vcr yet?
