I just bought a Streams and I’m liking it, but I’ve run into a little noise issue. I notice a consistent hum / buzzing when the vactrol/envelopes are opened up by the excite input. the hum doesn’t change, just gates on when the envelope is open at all, and gates off when the envelope fully closes. So when the envelope decay has almost faded out plaits, I can still hear the hum at the same volume.
The noise/hum is most notable in AD and vactrol mode with mod knob set before 2 ‘o clock (filter turned down). Becomes less audible very quickly when turning past 2 o’ clock.
Also the hum is present only when level knob is opened by the excited envelope or manually.
I know there is a voltage that is applied without input, but I’m getting the same issue with or without input.
