Dave Smith Instruments SYNTHESIZERS

I recently saw this on a post, 
For some reason, the analog osc's go down to a lowest defined note,
right after you release a key ,
This is what is causing my pain if it is true. Is there a way to get
rid of this action?

No offense to whomever made the claim at SonicState, but that just 
doesn't sound right.  If the analog oscillators switched back to 
their lowest possible frequency immediately upon release of a key, 
you'd hear it clearly with any patch that had a finite (non zero) 
release stage in the envelopes.  You'd also hear it with any "keyless 
drones" (patches in which both the amp and the filter are open 
without hitting a key).  I have a LOT of patches like these, and I've 
NEVER heard this behavior.  It would render the Evolver next to 
useless.

I have a good guess as to what is confusing the person that made this 
claim, though...

When using the sequencer:

- IF you program one or more "rests" for any of the sixteen steps,

- and IF sequencer track 1 is used to control the pitch of one or 
more oscillators, 

- and IF the envelopes have a long enough release segment, 

you can hear the oscillators (ANY and every analog and/or digital 
oscillator whose pitch is controlled by track 1) return down to 
whatever pitch is programmed in the patch as the "home key", if you 
will.  This is normal behavior, because the sequencer step in track 1 
on which you programmed a rest can't tell the oscillator(s) to play 
at the pitch that you want (the pitch of the previous step in the 
sequence).

If you're experiencing this, and it's a problem for you, it's quite 
easy to work around.  Simply avoid the use of sequencer track 1 to 
control pitch of the oscillators when you have programmed rests in 
track 1, coupled with long envelope releases.  Use tracks 2, 3, 
and/or 4 to do all the pitch work.

Actually, this same phenomenon would apply to ANYTHING you sequence 
with track 1, be it filter cutoff, pulse width, etc.  At each of the 
rests you program, whatever is being modulated by track 1 is going to 
return to its base value.

Make sense?  Hope that helps.  If it does, you can copy this message 
to the SonicState thread in which you found the erroneous claim, and 
maybe it will help someone else, too.

On the other hand, if you REALLY are having the oscillators' pitch 
shift down at the release of every key, and you're SURE you don't 
have one of the envelopes controlling pitch, I think it's time to 
email Dave Smith and tell him that you have a defective unit.  I 
really don't think that this will be the case, though.

Best of luck!

I really do appreciate all of the info. I saw this post on sonicstate
and it really did not make sense to me. However on some of my patches
i do get a stange low "note" on key release and i have to chop the
release on the filter and vca short to get rid of it. I am still not
quite sure why ths is happening. I feel the person that posted this
incorrect statement was having a similar issue. Ill let you know if I
can figure it out. If you know what I am talking about and how to fix
it so i can have the note decay, please let me know.
Cheers

So you're hearing this behavior when the sequencer is NOT running?  
Assuming that your Evolver doesn't have a real problem, I could point 
you to dozens of patches with long envelope release stages that don't 
exhibit this behavior.  Of course, you'd still want to know why it's 
happening in YOUR patch!  ;)

Check these points for starters:

1) Make sure that Env3 is not controlling pitch.  Set the Destination 
for Env3 to OFF.  If it's already OFF, change it to something else, 
then back to OFF again.

2) Go to each one of the four Modulators, and set the Destination to 
OFF (M1 through M4).

3) Set the Destination for each one of the four LFO's to OFF.

4) Set the Destinations for Mod Wheel, Velocity, Pressure, Breath 
Controller, Foot Controller, 

5) Make sure the sequencer isn't running.

6) Just for fun, hit the sequencer "Reset" button.  (That shouldn't 
fix any problem, but it will help ensure that you're playing at the 
correct pitch.)

(Note: With all the above points, you're trying to ensure that 
nothing is modulating pitch.  If any of the various Destination 
settings are already OFF, I'd switch them away from OFF, and then 
back to OFF.)

7) Try using a different MIDI keyboard.  There's an outside chance

8) Connect one, and ONLY one MIDI keyboard directly to the Evolver.

9) Disconnect any and all other devices (MIDI, audio inputs, 
computer, patch bays, etc.) from the Evolver.

Hope this helps.  Again, I want to assure you that this behavior most 
certainly does NOT happen on the two Evolvers I've worked with, and 
I've logged a lot of hours with them!

One other thing - make sure PolyChain (knob 2, main row 2) is set to 
OFF.  This caused me some problems until it was pointed out to me.

I added a sound to the files section. A lofi drum sequence modulated 
with
mod wheel and aftertouch.
Sounds like this:
