cool, glad you liked it ...
Bela and AE modular are a really great match, both really fun for DIY projects.
the glitches, not quite sure at the moment - I need to do analysis the data, it could be the z axis is not smoothed enough, or needs better scaling (*) - I also need to see if a different carrier set may be better (usually you run a test to see which set are most stable)
(*) the soundplane is a little 'unstable' with light touches, and it be this instability is pinging the filter/vca...as it didn't seem to happen with firmer touches. also Y is not smoothed, and I was passing this into a couple of VCAs, and a inverter... it may be rapid fluctuations there, might have been doing something to the VCA.
so, it will be interesting to compare this to Eurorack/Salt, see if the AE or patch is partly to blame 🙂
data - both cooked and raw are available, what I'm doing it using a cooked version, with the touch tracker code developed by madrona labs, as Randy has spent a lot of time developing and improving this. Its a little heavy on CPU, as its floating point... but does not have to be run at audio rate.
EDIT: interesting development...
on Salt/Eurorack, Im not getting the glitches... (except very infrequently with a one VCA and even thats unclear)
current thinking on AE/Bela:
something is accentuating a fluctuation, and pinging the vca/filter combo.. perhaps due to response rate/character of them(?!)
and/or
bela's analogs out are perhaps not as smooth as salts? a bit more raw? (perhaps salts are filtered a bit?)
probably need to log the data to check, and perhaps attach an oscilloscope too see how big the blip is...
