[sdiy] Midi oscillator!! (ot)

[cheater cheater]

Nope. Sorry if that's what it seemed like.
Samppa is a troll.
And when someone gives in to his trolling and starts a conversation,
thinking Samppa actually has a point, the troll is successful.
He's gotten banned from more online forums than I can count... he's
the public enemy #1 on the midibox forums, for example, where he used
to be known as 'Mobius'.
Just to give you a hint of his track record, just when I posted on the
sdiy list for the first time in long, he sent me..

(funny misspelling of lower class that be, by the way)

He'll often reply to threads on the list, but only addressing the
reply to the person's private address, with insults or just plain low
SNR.

Cheers
