Perhaps because a "problem" doesn't exist?
What if I like a "hard note?" Does a problem exist? Notwithstanding
potential key clicks on very fast rise/fall times, the sharper the note,
the better I like it. Someone replied a few minutes ago and indicated that
note instability is generally attributed to inadaquate power supply
regulation. Any of us running our Omnis on 20-Amp Astron supplies?
