I don't have Rosegarden listed in the "readable clients / output ports" but If I play my midi keyboard through Rosegarden and then out to ZynAddSubFx it works.
Thanks. That confirms that what I'm seeing in JACK isn't unusual or unexpected. On Tue, 24 Jan 2006, Mike Taht wrote:
It's probably not finding the midi device... do an strace on rosegarden to see what midi devices it's trying to open and see if they are in /dev
Checked first with lsof: Once running, with the device selected that I expect to see as the physical "MIDI out" connector on the CS46xx interface: rosegarde 25807 syl 14u CHR 116,1 125373 /dev/snd/seq For reference, aplaymidi (which _does_ produce MIDI output) also holds the same device file open: aplaymidi 25846 syl 3u CHR 116,1 125373 /dev/snd/seq so, alright, a trace of the rosegardensequencer process is in order ... In response to Markus Herhoffer's suggestion, though, I ran the strace test with JACK not running, and sure enough, I got the MIDI output, tried again without strace (still no JACK), and again MIDI output was working! I won't bore you with the strace output! :-) On Tue, 24 Jan 2006, Markus Herhoffer wrote:
Midi has actually nothing to do with Jack. Jack cares only about audio streams.
I'm not convinced of that. For example, I do need to "connect" (via qjackctl's "connect" screen, "MIDI" tab) "80:CS46xx" to "129:FLUID Synth" to be able to control that software with my MIDI controller.
As far as I know there are some problems in the compatibility of qjackctl and Rosegarden (described in "Rosegarden Companion").
I would love to get a copy of that. Anyone know of its availability in Canadian bookstores, or should I be looking to purchase a copy online?
So you should use only Rosegarden for linking the MIDI devices.
Ok, as mentioned above, I tested with JACK not running, and sure enough I'm now able to get MIDI output from Rosegarden. Thanks to all who replied about this! The beautiful sounds of my music theory final from a couple of years ago (ok, well, it's still beautiful to MY ears!) emanating from various MIDI synthesizers and a piano sample! :-) I continued testing and found that if I start JACK _after_ starting Rosegarden, it seems to do the right thing. Should I perhaps simply have Rosegarden start Jack, or am I asking for different trouble if I do that? (I do still want to use JACK because some of the applications I expect to be making heavy use of use it or require it ...) This software (all of it!) is such a beautiful thing! Thanks once again, and good night! :-) -- ---------------------------------------------------------------------- Sylvain Robitaille syl@xxxxxxxxxxxxxxxxxx Major in Electroacoustic Studies Concordia University Faculty of Fine Arts / Music Department Montreal, Quebec, Canada ----------------------------------------------------------------------
