Yeah, I have a couple of older model chips on my bench that used
seperate RAM, but it was still limited to about 400ms.
I haven't had a chance to play with them, but I believe someone
on synth-diy said the quality was not that great. Of course, I'm
not sure what they were comparing it to.
The interesting thing is that the VCO clock controlling delay
time can be varied with a resister. I thought about using something
like a vactrol to get VC delay.
