[TenTec] OmniV/VI cw characteristics

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?
