Clearly reproducable with 1 oscillator, no MODs, no PWM, and FILTER bypassed.
But is this important to fix? There is a very easy workaround: use 52 instead of 50. Is this creating problems for people?

It is consistently reproducable if portamento STMODE is LSTKEY. Here's what the manual says about LSTKEY: "When a new note is played, it will slide from the last key played." Put this way, if I hit C4 and then C5, I would expect both voices to glide from C4 to C5. But maybe this is impossible to implement due to key assign logic, who knows? Playing polyphonic portamento can also have weird and 'unexpected' results, but I would not call them bugs.

I could reproduce this, again with a simple mono patch, no MODS, FILTER bypass etc.
First hit the lowest key on the keyboard, then hit the highest. Then hit the highest again. There is a marked difference between the first and second time you hit the highest key.
However, I could not reproduce this after setting the OSC ENGINE to ULTRA FAST. But maybe my ears aren't up to the challenge... All the other modes did suffer from it, though.

Don't know how to reproduce this; I always use the pedal as a "latch".

Shouldn't we classify this as a bug? Page 54 of the manual says about polyphonic key pressure: "Although the A6's keyboard does not respond to this type of pressure, the A6's Voices *will* respond to poly pressure received from another MIDI device..." Well, clearly it doesn't. (Although the use of the word "will" here is interesting ;)


My 2 pennies,
