Doepfer

Excuse me Argitoth, but if you're so obsessed with pure sine waves, go
digital. Buy Max/MSP or learn SuperCollider.I thought we were using analogue
gear because of its colour and impurities?
At least I am.
And I'll say it again: Buy an A143-9 if you want nice sinewaves.
It goes far into the audiorange.
Check the attached picture.. An A143-9 hooked up straight to my Focusrite
Pro26 firewire interface.

greets,

Ernst
