Hello! While following the osc module tuning guide that was recommended to me in this post on the esp32 module thread, I noticed the envelope sustain button impacts the frequency of the osc module even when the envelope module was NOT in the signal chain. The signal chain was esp32-midi module output B → osc module pitch in → osc module triangle out → output module. When the envelope module was also plugged in to the board and the sustain button was engaged, there was a significant increase in pitch by ~40cents. Is this normal behavior for the envelope module?
I also noticed that the pitch would be different depending on whether any module would be plugged in at all. Keeping the same signale chain as above, just having another module plugged into the board at all would change the osc frequency by ~40 cents. Is that normal behavior for modular synthesis in general? Microrack is my first experience with module synthesis.
