Hi, first of all thanks for this excellent kit. The drums sound amazing, to me it sounds excactly like a TR808!
The problem: Like topic says, switching the Expander knob introduces different audible noises/high freq hum, mostly ranging from around 2khz and higher. They are not dependent of the level knobs, I can turn them all down and the noise is constant. Except for the master level, noises dissappear when I turn it down. Noise is constant until I switch the expander knob - then I hear another frequency range. There is noise present at all expander knob positions except all 3 NC positions (here it dissappears).
Anybody else have this same problem, or have any idea about a possible solution? I'm using an external 15VAC PSU at the moment.
Noise when switching expander knob
The problem is only there when I connect to the master output. Individual outputs are dead quiet. So it must be something entering the master section. It's not very loud but clearly audible when I apply even a gentle compressor.
Have you tried looking at those high frequency hums using a scope? Or just zooming in on the waveforms in a DAW?
Hey this topic is like a week old but I had a similar problem when I was controlling the Yocto in expander mode through a Midi Thru unit. Except it was a buzzy noise on all outputs. When I controlled it directly from my sequencer without the Midi Thru box the sound disappeared. Not really sure why a midi thru box, even a cheap one, would affect it that way, I would think it'd be totally removed from the audio path, but there you go.
