Midi CPU Program for simple keyboard controller

[theharmonium]

hey all ... So I have the controller built and ready to go but I’m trying to figure out how to program the midi cpu … I read through the manual but am still in the dark

Basically I have 8 push-button switches I’d like to use for basic program changes and one potentiometer to control an effect parameter cc#63 …

by the way I plugged the controller into my computer and used a program to determine what switches were sending what messages and noticed one switch was sending messages on both terminal 5 and 6 but I'm not sure why ... anyway i figured if both terminals were sending the same thing it wouldn't be a problem ...

So here is how I broke it down with the program numbers and terminals... anyone have any suggestions on how to program it:

Terminal 0
Push-button Switch: Program change # 120

Terminal 1
Push-button Switch: Program change #122

Terminal 3
Push-button Switch: Program change #124

Terminal 5/6
Push-button Switch: Program change #127

Terminal 8
Push-button Switch: Program change #126

Terminal 12
Push-button Switch: Program change #114

Terminal 13
Push-button Switch: Program change #118

Terminal 15
Push-button Switch: Program change #116

Terminal 21
Potentiometer: MIDI Controller # 63

Hi theharmonium,

Here's a sysex configuration for your application. Instructions for sysex are here:

http://forum.highlyliquid.com/showthread.php?t=280

My best guess is that there's a short circuit between control terminals 5 and 6--you might want to double-check the wiring.

Let me know how it turns out. :)

[theharmonium]

its coming together great ... i have all the program change switches working and im begining to understand a little of the programing ...

but i have run into one issue on the potentiometer (now on terminal 23) ... and i can't seem to figure out whats wrong ... when i twist the potentiometer it goes to the right effect (cc#63) but it only registers a value of 127 at each interval

also the potentiometer will occasionally send a note on or note off message for Bd5 ... can't seem to figure out how to make that stop either

any ideas?

[John]

Please post a sketch or photo of your wiring.

Also, please post a configuration dump or the configuration sysex that you're using.

i think i have the potentiometer working ... i might have had a short in terminal 23 and / or wired it wrong ... but after moving it to terminal 21 and switching the wires everything seems to be working ... although, I am still getting a Bd5 note on/off message occasionally from the potentiometer ...

here is the sysex text w notes...

Can you do a config dump and post the results? If using SendSX, send the following to the MIDI CPU:

F0 00 01 5D 04 00 7F 00 F7

...and a large amount of data will be sent in return. It might help us figure out what is causing the unusual behavior.

Also, when changing control terminals for the CC potentiometer, it can get confusing. Here's the config chunk for CT 21:

15 00 04 00 3F 08

For CT 23, you'd want this:

17 00 04 00 3F 0A

Note that the sixth byte has changed. See the "analog input data" table in section 2.2.2 of the firmware user manual. The last byte tells the MIDI CPU where to get the CC value from...

[theharmonium]

thanks for the help ... i definitely overlooked the last byte for terminal 23 ... here's the code from the sysex dump

I am still getting a Bd5 note on/off message occasionally from the potentiometer ...

Control terminal 22 is configured to generate note #82 (52h, or Bd5). This is part of the "factory default" config that is still there, since we haven't re-configured CT 22.

So it seems that there's a short circuit between control terminal 22 and control terminal 21, where the potentiometer is connected.

Can you double check the wiring? With the power off, check for continuity between control terminals 21 and 22. This would explain the generation of the note based on potentiometer input.

If you want to go back to using control terminal 23 for the pot, that's fine--just be sure to correct the configuration as I described in my previous post.

I probably shorted 21-22 in my soldering mess (still learnng how to do it well) ... i switched it back to 23 and ran the new code and its working great ... I twisted the pot for a good 5 minutes watching the output in a midi monitor program and not a single rouge message or Bd5 ... thanks for all the help ... hopefully I'll get a pic of the controller soon to post ...
