I’ve had that a few times, it was just that one of the drone controls wasn’t really truly all the way down at zero. I might have to build in a buffer zone on the knob.
Can you describe what you mean a little further? If the drone knobs are being used, they are basically attenuators for the oscillators. If being played via keyboard, the velocity will impact how loud each voice is.
That’s a tough one, part of the charm of the original hardware is the inherent limitations. Your suggestion is an interesting way to go about it.
Total Feedback: When this is toggled on, any voice that has its modulation source set to “LFO / FB” will be modulated by the final output of the synthesizer, that is, the audio output after the distortion. The entire synth is feeding back into itself for modulation.
Numbers: Normally Voices [1-2 & 3-4] and [5-6 & 7-8] act as pairs for modulation. If the numbers switch is active, Voice 1-2 will be a modulation pair with 7-8 instead, and likewise voices 3-4 and 5-6 will become a modulation pair. It’s not terribly intuitive on the hardware, either.
There should be hover tooltips explaining those, and I’m adding tooltips for every control.
Thanks for taking the time to write up your observations!
