Real actual, not made up, numbers....

Maximum Decay Times of some common A. or V.A. synths:

Roland SH-101 			12.5 seconds
Roland SH-09 			14 seconds
Vermona Mono Lancet 		15 seconds
Arturia Minibrute 		14 seconds
Access Virus TI2 		42 seconds
Waldorf Blofeld 		50 seconds
Studio Electronics ATC-1 	37 seconds

Test patch: VCA gated, A:0 D:FULL S:0 R:0, ADSR modulates LPF cutoff 
100%, LPF Freq:0, Res:60% to 100%

Did not bother measuring the Doepfer ADSR as the timing on that module 
is pre-cambrian.

With total respect and apologies for my silly numbers of yesterday, I 
still find the decay time on the sub-phatty unsatisfyingly short.

Its perhaps my playing style, but the first thing I do on any new synth 
is dial up my favourite legatto patch and start popping a riff.

10s (or less) decay does not cut it for me.

I wonder if this can be changed on the sub-phatty?

I can't be bothered to look in the manuals, but I'd put money on the 101 and 09 also having 10 second decays. The MC-202 certainly has no more than that...
