Hello. I recently purchased my Lyra 8 and I noticed when sweeping through the pitch with the tune knob for oscillators 5/6 (and 7/8) that if the tunings are really close they seem to cancel each other. The audio drops in volume significantly and is the signal is distorted. This occurs only when playing the two together though. if i play each separately they each sounds normal. maybe there is some sort of comb filtering happening or antiphase cancelation. but it only seems to happen on oscillators 5/6 and 7/8. It is most noticeable on 5/6 and 7/8 when I set everything to the left turn all modulation switches off. put the master pitch at 12 o’clock. and set the sub tune knobs to 2 o’clock-ish. Then slowly adjust the knobs until  the audio drops and distorts. Do others have this issue? is this expected behavior?
