Title: change midi channel with one button
Post by benhoff on Apr 22^nd, 2007, 4:23am

Newbie here. Sorry if this is already a feature. I love midiox and think it probably saves thousands of hours for people.

I'd like to be able to program a key that changes the channel of the midi output from an Edirol PCR-M30. It would be very cool to be able to change the instrument for sounds created with soft synths. I'm thinking that each instrument could be on a different channel and assigned a different channel to receive.

Edirol said they thought it was a good idea to be able to program a button to change the midi output but that it isn't implemented and I'm pretty sure not in the newest keyboards they have out.

Thank you for midiox and midiyoke. Sometimes thinking about midiox is what gets me out of bed in the mornng, even though that sounds weird.

The way I do this is with Patch Maps. When I hit Program Change #1, the patch map loads up a data map that sets the MIDI Channel on all messages to 1. When I hit PC#2, messages get Ch 2, etc. My Evolution MK-249 has Program Change buttons and I can also send PCs from my FCB-1010, so this works well for me.

It works. There should be some exclamation points but I restraining myself.

Thanks again for the help on my other post. Can you tell me a way to program midiox/yoke so the keyboard I have, which doesn't seem to have a channel change ... to be able to use ... say the extreme high keys to trigger a program change which could set up a different map?

Someone, I think / not sure, said that the key stroke would have to be mapped to a program change and then routed back into midiox to be the stimulus for a map load.

I'm not sure how to send an event , if that's what it's called back to midox from midiox

It's ok if this doesn't make sense. I'm struggling. :P

You need need to use a MIDI Yoke junction. Write the program change event out down one end and have read it when it comes back in. I don't think anyone's reported success with this yet. The "two copies of MIDI OX" trick seems to garner more success reports. However, until someone tells me the loopback doesn't work, I'll keep suggesting it! :P

MIDI OX (key>pgmChg)->MIDI Yoke Out:1
MIDI Yoke In:1->MIDI OX (patch map)

Make sure that's the only stuff going around the chosen loopback junction -- use a separate junction for anything else you're doing with MIDI Yoke.

It's not apparent to me how a midiox midi out event can be directed to a specific midiyoke port (or whatever it's called). I mean there seems to be no way to select what port an event is sent to....

however, the idea of using two instances of midiox works great.
