Hi @giuliomoro and bela community,
I have been finishing the design of my latest prototype of Knurl with some doubts about the application of Trillcraft in its interface
Currently in the patch I am adding a gain a 15dB. Doing it I start to listen some noise sounding like there is a ground problem. I tried to avoid it by:
- All cables are shielded
- The sensor is placed far from the wifi dongle
- connecting all unsed pins from trill to ground
- I tried connecting the ground of the trill with the ground of the signal and it doesnt seem to make it a difference either
Using a low pass filter of 350 the noise is reduced significantly, but the sound of the instrument as well. I tried adding a notch or band pass filter but it seems the noise has different frequencies
I wonder if someone has any advice how to eliminate this problem
Thanks in advance!
Ps: The sound signal is completely clean when the trill isn't connected
