Patches and discussion for Ensoniq VFX family

HI all,

This is a cross post.  I sent this to the other VFX list.  There is a
patch attached to this.  I mention a variation to this patch at the
bottom of this message.  It looks like I may have already made the
changes that I suggested down there.

On another list, (probably SYNTH_L) a fellow mentioned that when he
forced an octave pitch bend (downward) on a sawtooth wave, his VFX was
mistaken for an xpander.  I'm sorry I don't have the name.  A hard drive
failure wiped out a lot of saved email.  I'm interested to hear your
pitch ben tricks.    

Modulating pitch with the pitch bender or another source (mod wheel in my
case) does not have the same effect as just transposing the pitch down on
the "Pitch" page.

Well I got to exprimenting.  I set the mod wheel to modulate pitch on the
"Pitch Mod" page.  As you get into the higher numbers for "MODAMT"
(modulation amount),each increment broadens the range of the mod wheel by
somthing like a semitone.  The smaller numbers (1,2,3, etc.) seem to be
closer together, i.e. to bend an octave with the wheel the setting is
+/-62 after that each octave is 12  numbers away.  You will have to go to
the "Pitch" page (not "Pitch Mod") and fine tune to standard pitch. 
Also, once you've bent the pitch down you might want to transpose the
patch up to the octave you started with.  

Bending an octave down makes the sound less bright but it sounds
different than lowering the filter cutoff.  The sawtooth wave I was
working with got less buzzy.  Buzzyness could be heard on the unbent
patch when the filter was turned way down.
What happens whe you bend up an octave?  The sound gets brighter.  I
suspect this is again a different sound than you would get adjusting the
filter.  Definitly when you start to get distortion.  The distortion
doesn't seem like a bad thing necessarily.  When you bend the pitch up a
few octaves and then transpose down to mormal pitch you get distortion
like you usualy get on higher pitches using a bright sound.  
  
To bend down an octave:

Go to the "Pitch Mod" page.
Set MODSRC to =WHEEL
Set MODAMT to = -62
Go to the "Pitch" page
Set FINE to = -9
You can transpose the sound back to its original pitch on this page.  It
wont sound the same.

To go UP two octaves:

Go to the "Pitch Mod" page.
Set MODSRC to =WHEEL
Set MODAMT to = +74
Go to the "Pitch" page.
Set FINE to = +18
Transpose down to the octave you want.

Don't forget to push your Modulation wheel all the way forward.


To go more than one octave up or down, just increase/decrease the MODAMT
parameter by twelve. 
Then, fine tune the patch by transposing it to the same octave as another
patch that is in tune.  Now you can adjust the FINE parameter on the
"Pitch" page until the beating and wa-wa effect go away.  Needless to say
that you want to turn of any LFO modulation in both patches when you are
tuning.  

I've attached a patch that uses this trick.  It won't sound right unless
you push the Modulation Wheel all the way forward.  I look forward to
hearing what others do with this trick.

Make a joyful noise,

P.S. Dont forget to push th Mod Wheel all the way forward.  And try all
four patch select settings.(OO, *O, O*, **)  

P.P.S. One more variation I couldn't squeeze in is this:  You'll want to
push the patch select button (It's in the "Performance"section on my
plain VFX) an set this patch to HOLD.  Go to the "Select Voice" page. 
Now press both patch select buttons (above the pitch bender) hold them
and play a note on the kwyboard.  Now remove the parentheses from the
vioces in the upper right corner of the display and the center of the
lower line of the display.  I hope this was fun.
