Trying Ebband LFO, wonderfull! sounding great in audio rate as an oscillator, and VC of slope,etc... Would be perfect as an aditional oscillator for my Easel, I see it have a V/oct input I don´t know if could be moded for 1.2V/oct?? Thanks!
It's certainly possible! I'll see what I can do when I have time 😉
ok! trying again and its already working!! it was a fault compiling the firmware without the buchla flags. What is not working is the bipolar output, in LFO mode only the upper part works, I think It need a kind of offset
So does EbbAndLFO track correctly with 1.2V/Oct input if the compiler flags are enabled?
For the bipolar output: Do other applets successfully output negative voltage? I don't know much about these Buchla variants, seems like it's only positive voltage...
yes! working with 1.2V/oct usaing the buchla_4U and buchla_cOC flags. It really open a lot of nerw possibilities using the "extra" oscillators. About the bipolar, I need to check but yes, bmaybe all not tweaked applets does the same and only work half of the range.
This seems mostly resolved. Looks like the appropriate build flags will cause all inputs and outputs to be scaled appropriately. I'm still not sure what should be done about a bias offset for bipolar outputs... and I can't test this myself. Feedback from more Buchla users would be helpful.
I added some configuration to the platformio.ini file to enable building for Buchla, in case others want to try it out:
pio run -e buchla -t upload
I didn't put the -DBUCHLA_cOC option in there tho, you might need that.
