[sdiy] favorite adsr?

[Florian Anwander]

Hi Dan

> so i guess i should just change my question. What are peoples favorite ADSR's to build?
My favourite ADSR is not ADSR ;-)

I found that I use ADSR's most times in two ways: either as a "peak 
envelope" for sequencing (zero attack, no sustain, some decay but decay 
is not stopped by the key release, which is difficult with ADSRs, 
because you have to set D and R at the same value) or as "string 
envelope" (some attack 100% Sustain, some release). The typical "brass 
envelope", which requires all four parameters of the ADSR I use only rarely.

So my favourite envelopes are not ADSR, but switchable between ASR and 
AD as in the Moog Rogue. I recently copied the Rogue envelope schemo and 
drafted a pcb, but did not try it yet in reality. ->
