FW: FW: [motm] Super VC DADSR EG

FW: FW: [motm] Super VC DADSR EG

2001-04-01 by Tkacs, Ken

Yeah, that's what I'm describing. Except that you would have enough control
over the angle of that second "D" to be able to set it to "infinite"
(Sustain) if you wanted to.

Err, pardon me, but isn't it a fact that there is NO sustain level in
the struck bar scenario you mention below? Sustain by nature is, well
sustain. Sounds like what you want is ADDR or something.

My Chroma has an EG setup that is simple, but flexible enough to do
what you describe.

Basically, it has no ADSRs, but instead 4 ADRs. The Decay can be set
to infinite to give you an ASR. You apply 2 EGs to the same VCA or
VCF to get complex envelopes. The sustain level (if set to ASR) is
controlled by the CV amount applied to the target. I have some
effective analog piano patches which use 2 EGs with fast attack, one
with fast decay and no release to do the attack transient, the other
with slow decay and short release to do the body envelope. The
attack, decay, and release time are modulation destinations. There is
also a facility for a velocity switch level, which allows EGs to be
set to turn on or off above/below a threshold. Pretty advanced for
its day.

Instead of a big complex module, maybe this would be a more useful
model for a modular - a 1U VC ADR/ASR that you can gang for more
complex stuff.

Hey oldtimers - remember when we hashed out our 1U EG designs a year
or more ago? I still have 2 or 3 panel mockups of the results.

Or dual AD/AR units -- doesn't that sound familiar. But I still find the VC
inputs to an EG to be very useful so these modules wouldn't address that.

I don't remember this, maybe you can pass it along. Any thoughts on a MOTM
style panel for the Blacet EG since they will be available sometime soon?

If anybody wants to see the results of the list discussion from last
year about 1U EGs, I have three panel mockups uploaded.

All three feature a ADR/ASR mode switch.

The first one has unattenuated A and R VC inputs, plus an attenuated
input for simultaneous VC of both A and R.

http://motm.retrosynth.com/moe_stuff/future_motm/m810.jpg

The second drops the simultaneous AR VC controls for the addition of
an END jack to facilitate chaining or LFO behavior.

http://motm.retrosynth.com/moe_stuff/future_motm/m810r2.jpg

The third one replaces the AR VC controls with a gate delay and CV
input.

http://motm.retrosynth.com/moe_stuff/future_motm/m810r3.jpg

Actually, having your choice of all three would be very useful.

[motm] Super VC DADSR EG + Gate/Trig Delay

2001-04-02 by Tentochi

No manual trigger buttons. Would those be included on the gate/trigger
delays???

What controls would the gate trigger delays have???

Gate/Trigger In Jack
Gate/Trigger Out Jack
Gate/Trigger Inverted Out Jack or Gate/Trig Reversible Attenuator Knob
Gate/Trigger In LED
Gate/Trigger Out LED
Delay Pot/Knot
VC Delay Jack

Anything else?

Has anybody considered the Yamaha CS approach ?
Sustain is always "in the middle" (zero), and you have two
individual sliders for positive (Attack-Decay) and negative
(Attack-Release) amount. Excellent for VCFs, once you get
used to it. Unfortunately not so usefull for VCAs ...

There's one on the CS-40M (AR EG dedicated to the VCO ... there are
also AR EG's hardwired to the LFO and Ring Modulator freq, in
addition to the ADSR EG's for VCF & VCA - now THAT's a synth with
sufficient number of envelope generators, especially since most of
them can go either + or -). The CS-15D (the one with presets, not
the "plain" CS-15) doesn't have one (VCO EG), though. I'm not sure
about the "plain" CS-15.

Hi Juergen n All !

That must be on the bigger cs synths : cs50,60 etc

But sustain "in the middle" is what i meant by "let's have outputs
biased around sustain" ... both outputs can be easily provided . (if
there's space for the jacks :) )

Come to think about it, those "split attenuators" would be a great
addition, limiting the range in this way . More possibilities than a
simple input attenuator . It would have to be incorporated in the
module itself, no ? Hmm, i'd like to see a schematic for this .

As you say, this is useful only where negative and positive
modulation can be used around a set point . VCA is not one of those
(except for drones maybe), vco pitch (anybody familiar with the CS15
key pitch eg?), pwm, vcf freq, and resonance are, and possibly more .

btw, i had the impression this was not about 1u eg's . We got one
... ;^P

Bye for now .


Keep 'em oscillating :)

Korg had an ordinary HADSR in the MS-20 that had a normal output
(hard wired to VCA) and a "Sustain biased" output (patchable). This
is easy to implement (subtract sustain value), but *not* the same
as in the Yamaha synths.
In the Korg version, decreasing the Modulation Amount means decreasing
both AD and AR parts. And decreasing Sustain meains increasing AD
and decreasing AR.
In the Yamaha version, you can alter the AD and AR amount independently.
This is easy to implement as well, but not easy to derive from a standard
ADSR.
