system exclusive mesages MIDI



Could anyone please help me out.
How do you tell your sequencer program(I use cakewalk) to transmit system exclusive mesage
(for instance: change cutoff frequency) to your
midi synth.
(I've menaged to record this information from JX-8P to cakewalk and now It's saved in sysex wiew, but I don't know how to activate this thing back to the JX-8P.)
I'm dealing with this for about a week and I'm getting really frustrated. I've even dreamt about it. Really!
Thanks for help!!!

Hi Kristjan

I'm not sure I understand. Are you trying to record a filter cutoff "performance" and play it back?

To test, you might trying downloading a demo version of another sequencing program, recording into that and seeing if it plays back. If so, then Cakewalk is the culprit. Otherwise, the JX might be.

This is a situation where its great to have a MIDI tester. Then you can see what's going in and what's coming out. I use the Studiomaster MA36. They'll have to pry it from my dead, clutching hands.

I think they mean "Continuous Controller message".

Look that up in the Cake Walk documentation and make sure that CC (Continuous Controller) stuff is not being filter during record.

Also this data must not be filtered on the way out of Cake Walk or else the JX-8P won't recieve it on play back.

Hope this makes sense.

If you've seen that there is a recorded sys-ex in the sequencer, look for the litterature about your synth, there should have some switch or midi settings on your synth that permits sys-ex data in both ways(back and forth) Like the Juno 106, there is a 3 position Midi switch at the back(right side) of the keyboard.

And do you see Midi activity on your MIDI interface when you move knobs on your synth?

I don't know how Cakewalk handles sys-ex but usually, when it is recorded, you just have to play back(play enable) this track.

Because if the settings are OK on your synth to transmit and receive the data, your sequencer should handle the rest easily.
