Patch Changes Not Happening On Midi Channel 1 Options

[karambos]

Can someone help me with the following:

I'm in performance mode on my Roland JV 1080 which means I can play up to 64 voices on up to 16 midi channels. I've set up my performance on the synth as I want it played back by the sequencer; in other words the right patches(sounds) on the right midi channels and the right midi channels assigned to the right arrange window tracks. Just as I want it.

I've set up the Multi-intrument (in the environment in Logic) to communicate on all midi channels, (by selecting the multi itself and not one of the individual sub-channels), and selecting "All" where it says "Cha". Everything works fine. Logic records and plays back fine; all the right instruments in all the right places. I do a bulk dump and then I can close the song, re-open it and it plays back just as I want it to. No probs so far.

Now, lets say I want to change a patch in the performance; in other words, I want a different sound on a particular midi channel. I can either go to the synth and press "parameter" followed by "wave" and select my new patch directly using just the synth. Or I can ALT+<double-click> the track in my LOGIC arrange window that I want to change. This opens a window from which I can select any patch. If I change the patch here, I can see the instrument name changing in the arrange window and I can see it changing on the synth too (providing I press <PERFORM>+<PATCH> and then select the corresponding Part). I can do another bulk dump and voila - change done.

Or is it? This procedure works fine for all midi channels APART FROM MIDI CHANNEL 1. I cannot change the patch on midi channel one from within LOGIC. I have to do it direct on the synth. Any ideas why?

thx
