Changing Cutoff at CC 74

[vorptronica]

I've built a minidexed on a Raspberry Pi Zero 2 for use with my Linnstrument. It works! However, the Linny defaults to sending CC74 for vertical movements on the keypads. This results in an undesirable "cutting off" of notes from inadvertent finger movements. Apparently minidexed is interpreting 74 as a filter cutoff, which makes sense. Is there a way to change this in the ini's? Or do I need to tweak source and rebuild? I've found many occurrences of Freq Cutoff in the source but I've never built this project and could definitely use some help with that if it's necessary. Ideally I could build on an arm Mac, but I can do Windows. Linux would be trickier but could figure that out too. Thanks for the assistance.

I dont think you can remap CC codes in the config.
Have you seen the wiki ?
This might be easier than setting up a full local dev environment for small tweaks like this.

BTW, I can only find one occurrence in the source:

penfold@precision:~/github/MiniDexed/src$ grep FREQUENCY_CUTOFF *.cpp *.h
mididevice.cpp: case MIDI_CC_FREQUENCY_CUTOFF:
midi.h:#define MIDI_CC_FREQUENCY_CUTOFF 74

Hi @vorptronica.
You should be able to let GitHub do the compiling as @penfold42 pointed out.
Since I don't have access to a Linnstrument, can you exactly describe which CCs should be ignored and/or interpreted differently and/or swapped?

Hi @probonopd . It's just the CC 74 as far as I can tell right now.
It is mapped by default to Linnstrument vertical pad movement and, for my playing at least, essentially kills the tone very often when playing. normally.
I can configure the Linnstrument, I believe, to stop outputting this CC but it IS useful in other synths and I'd rather just modify minidexed to ignore it.
BTW, I spun up an Ubuntu VM and tried compiling the source (before any mods) but it fails with:

+ make mrproper
Makefile:3: Config.mk: No such file or directory
make: *** No rule to make target 'Config.mk'.  Stop.

I've never built on Github so that's a mystery to me but I'm sure I could learn.
I'd also like to play around with enabling MPE for pitch sliding and such in the future so it would be valuable to me to figure out.
Thank you!

Have you tried, e.g., RPI=3 bash -ex build.sh?

[vorptronica]

I can try that, thanks.
So far I've been copy and pasting the script under "Bulding Locally".
