I am getting an annoying 1kHz noise (and resonances at 2kHz, 3kHz) with the Daisy in the Terrarium pcb. I can turn it on and off by increasing the processing that the Daisy does. Is anyone else experiencing this with the Terrarium specifically?
There is some talk of a 1kHz noise on here on the Electrosmith forum, which suggests to "increase the callback frequency" above human hearing or use a DC-DC isolator like in the Daisy Petal schematic (page 4). Adding a DC-DC isolator to the Terrarium build I have is doable but a bit tough, does anyone know how I could increase the callback frequency or what that means? Is that just raising the samplerate for the Daisy? I attempted to raise the samplerate - but either I was not actually doing it or it did not remove the 1kHz noise.
I can upload a noise_test.bin file where the 1kHz noise can be flipped on/pff with the footswitch if that is useful.
