[sdiy] Delay / Reverb options

Hi,

this sounds so good, even if the tube ends up about 10 meters long to get a
good time, its such an odd sound...

This is also a good point..
I hope to have a go at a delay/reverb unit soon, using a processor, ADC and
DAC and s chunk of sram,
hell if quantec can do it with a 6809 I can do it with a modern processor!

Ive looked into some opf these, the one I found was a SIP module, with
delay/reverb/chorus/flange/etc/etc
but it was mono in, stereo out but had only an 8Khz bandwidth :-(
It used a DSP needless to say ... looked nice though..
