<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:EN-US">So far the MIDI channel is selected at power up. (channel 1 default).<br>
But if you keep pressed one of the first 16 keys down at power up<br>
this will be the new channel number.<br>
By the way this beast has its complete internal synth<br>
with a genuine ARP VCF module !<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:EN-US">Back to my needs..<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:EN-US">No way I’ll get back to my original HC11 machine code (yes machine code) to include<br>
any MIDI channel editing since it will also involve salvaging the wood housing<br>
for some footswitches..<br>
The easiest way so far is a transparent MIDI IN/OUT device<br>
that will read 2 x UP/DOWN footswitches, display the new channel number<br>
on 2 x 7 seg. Display then grab any incoming MIDI commands that has MIDI channel number<br>
on the MSB side first byte, then replace it and send the edited command to the MIDI OUT.<br>
All other commands will get through this device untouched..<br>
I could even have another untouched MIDI OUT that would keep<br>
the original Bass pedal channel for other MIDI devices to drive..<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="mso-fareast-language:EN-US">These are my thoughts so far..<br>
Thanks for your curiosity Tom.<o:p></o:p></span></p>
