Although Bob's AD patch was new to me, I have used a similar patch
for a more complex EG. For those of you who don't have a Serge ADSR
(or could sometimes use an extra) you can create a close approximate
using a DSG/DTG and an ACPR Active Processor. Keep in mind this
requires an actual *gate* source - such as TKB KP - to function
properly.
Gate in -> SG #1 trigger in AND SG #2 signal in
SG #1 out -> ACPR input #1
SG #2 out -> ACPR input #2
Attack time set by combination of SG #1 rise and SG #2 rise
Decay time set by SG #1 fall
Sustain level set by ACPR 1/2 pot*
Release time set by SG #2 fall
* full left produces an ASR, as with any ADSR at max sustain level
With a DSG you can achieve separate voltage control over attack
and/or decay (SG #1 rise and/or fall), sustain (ACPR VC XFADE in)
and release (SG #2 fall). Using a DTG limits your CV options and
requires a signal in mod for TG #2. However, a signal input is not
needed for TG #1 so you can still pull off the basic ADSR if you
have an Animal DTG or a DTG with mixed mods. I have also used a CV
processor in place of the ACPR but sustain is somewhat trickier to
get right and you lose the sustain CV option.
Insert a third SG or TG patched as a gate delay and you're very
close to full DADSR functionality:
Gate in -> SG #3 trigger in
SG #3 output -> SG #1 trigger in AND SG #2 signal in
Because of the voltage addition, the "patched ADSR" output is
usually hotter (higher voltage) than that of the Serge Extended
ADSR, so you will most likely need greater CV attenuation at your
destination input to achieve an equivalent amplitude swing as when
using the dedicated module.
I'll try to post an audio clip within the next day or so.
Patch on,
