Midi-Bug in Combi-Mode?

Lennthorpe · Post by **Lennthorpe** » Tue Mar 04, 2008 9:14 pm

Since this is my first post in this forum, I'd like to say "hello everybody" !

While transferring all the sounds (4 hour program with my band) from my 11 year old Trinity to my new M3-61, I stumbled upon this issue, which seems like a bug to me. Or maybe I'm just missing something!?

1. Set up a combi with two different sounds, one on midi-channel 01 the other on 02 (on Combi P3).
2. Set the two timbres to "int", all other timbres to "off" (on Combi P3).
3. Switch to global-mode P1 and set the midi-channel to 01 and play the keyboard. You'll hear the sound you set up on channel 01, not the one on channel 02.
4. Set the global channel to 02 and play the keyboard. You should hear only the sound on channel 02, but actually you'll hear both sounds (at least my M3 behaves that way).
5. Try the other channels 03-16, you'll always hear the sound on channel 01.

It seems that setting a timbre in a combi to channel 01 makes it behave as if it has been set to "gch".
I'm using OS Version 1.1.1.

If anyone could please check if this can be reproduced on another machine!? Then this should be addressed to the bug fixing list.

Thank you.

Hi Lennthorpe,
I think I know what you're trying to do here. And I've created some custom Combi's myself for live preformance.
My intention was to have quick program changes with a single button push.

The solution is really quite simple, if this is what you're trying to do.

You don't have to go to the global mode to play the sounds assigned to different channels of a combi, you simply just hit the corresponding number of the buttons 1-8 on the left hand side of the module where the sliders are.

Hit button 1 and there's a piano, hit button 2, there's a string sound...for example. The nice thing is that you have the sliders for volume control and other parameters. An insert effect on up to five of your assigned sounds is there for you also.

And of course you can save this custom Combi for instant recall!

Hope this helps!

Hi Lenn:

This one had me going for a few minutes, but I found it. It's not a bug.

In a INIT/default Combi KARMA Module A is set to run and it has THRU enabled. SO KARMA is rechannelizing the active keyboard always back to channel 1.

Go to P7 and turn off the THRU parameter on the right side of the screen alongside Module A. That'll fix it!

Regards,

Jerry

Thanks Jerry, it works perfectly now. A tricky one...

You're right, this is what I'm doing here. Actually, I'm using the mute-buttons a lot to add a sound here and mute one there, but in this particular case it is not working for me. I have a multiple layered and splitted sound (for bridge and chorus) and I have to switch that with a single organ sound (for verses).
Muting 10 timbres at once and unmuting 1 timbre is not fast enough this way, so I decided to do the good old midi-channel switching.
Another approach would be setting up the organ in program mode and switch between combi and program mode, which I also did a few times on the trinity. The disadvantage is, that it kills all sounds and effects when switching modes. This is not happening when switching midi channels.

While we're talking about this:
I thought about a mute-group feature in combi mode, that would allow the user to mute a defined group of timbres with a single button press. This would extremely improve the live performance abilities. (Maybe off-topic here...)

On this topic, I'd also love to see a way to switch between sounds easily in a combi. It'd be great if muted sounds didn't affect polyphony or if there was not only mute and solo options, but also an OFF option for each part.

There is a trick way to do that already - use the KARMA Timbre On/Off parameter with no GE's running. I don't have time to explain in great detail, but do a search, I've discussed this many times before. here and at KARMA-Lab.

It's very cool!

OK, I guess I found the discussion Jerry is talking about:
http://www.korgforums.com/forum/phpBB2/ ... hp?t=24350

That's a useful trick, I now have to rethink some combis I did already...
I've got the Karma-switching working in the before mentioned combi and it is fast and easy to handle during performance.

Thank you again, Jerry.
