This sounds good but ... I must be missing something : In patchage, ghostess now shows a different-coloured (brown) MIDI-in, which is a JACK-MIDI in. Fine, but how do I connect this IN to my keyboard MIDI-out ?? Patchage will not accept to do so. Is it even intended to work like this ? Thanks for attention.

The only ones I know of that support it officially in released versions (please reply if you know of more) are Ghostess (Sean Bolton's DSSI host) and Dino (my sequencer). There is a patch for Zyn and the SVN versions of Ingen (Om) and Specimen supports it. Connecting JACK MIDI ports works fine in Patchage and QJackCtl, although they appear in the "Audio" tab in QJackCtl. Dave Robillard also worked on MIDI in Ardour during the summer, so I suppose there is some kind of support there too. > 3) Does such support require a major rewrite? Depends on the software. If you are doing a lot of MIDI processing in another thread it may take some hacking, but if you just read ALSA MIDI events in another thread and pass them to the JACK thread using a ringbuffer or something similar it's easy - just get rid of the extra thread and the ringbuffer. I wrote the patches for Specimen and ZynAddSubFX, and for Specimen (which pretty much does that) it was really easy, while it was a bit trickier for Zyn (which does a lot of MIDI processing outside the audio thread). -- Lars Luthman - please encrypt any email sent to me if possible PGP key: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x04C77E2E Fingerprint: FCA7 C790 19B9 322D EB7A E1B3 4371 4650 04C7 7E2E
