DIY Pitch to Voltage Converter

2001-02-10 by Tentochi

Paul hasn't been to keen on doing a Pitch to Voltage Converter from what I
can remember.

Here is one to check out.

Larry,
Send me a copy of the Schematic, I'd like to give it a try after I get
the interval switches to work.

This is the Harry Bissell P-to-CV I wrote the list about earlier.  I have
the PCB and it is on my project list.  But, I am having trouble finding the
MAT transistor pair.  I went to the analog devices website and it wasn't
working well.  anyone know what's going on with that?

I have a parts list for this thing too (with Mouser #s).  And, there are two
different version of the schematic. The original PCB was designed to go in
an Etherwave where you would have 3 outputs.  1 = CV based on osc pitch
(right ant)  CV based on volume ant (left). and a Gate based on moving your
hand in and out of the volume antenna range.

I think Harry told me that the gate worked best if the Etherwave volume
function was tuned to work in the non-tradition mode of closer = louder.

If you are thinking about this as a stand alone project (as am I), then the
schematic is altered as a few parts left off to forgo this gate function.  I
have a copy of this altered schematic direct from Harry if anyone wants a
copy.  I also plan to see the wild man in March.  Apparently, he has this
thing working in conjunction with some kind of quantizer that I have to put
my eyes and hands on to try and understand.  That's one more reason for you
to be sure and make the AHMW thing this year Shemp.

Hey thats ME !

The PV-1 was layed out for the MAT-01, Mat-02, or
LM394 (i believe in overkill) but Bob Moog's original
version called for the CA3046.

There is a "playpen" area of the board which is
drilled
for a 14 pin chip (CA3046) with two additional pads
for the tempco. Those "reasonably skilled in the art"
could hack the 3046 in without much trouble.

Personally, I'd use the 2SC1583 pair  (of TB303 fame).
This is reasonably cheap, and a better tranny than the
3046.

Ask TomG on the EFM site, I think he can sell both the
tempco and the 2SC1583 (where I got mine...) or since
this is Paul's list (hi paul!) you can buy the tempco
resistor from him also.  The PV-1 boards are still in
stock at this point.

"Wild Man" is it ???

I have been gone for a few days.  If you haven't already sent it to the
list, would you mind doing so.  I am sure a lot of people would appreciate
it.

Cheers!

Re: [motm] DIY Pitch to Voltage Converter

The statement "the gate works better if the volume
control is reversed" is not correct.  I like the
reversed volume control, but the circuit does not
care.

The gate circuit is a must for the non-reversed
etherwave. This means you must have "both hands" on
the
wheel (antennas).  The mods I did to the circuit give
a very sharp cutoff in pitch... the gate is either off
or on, with no chance of dithering. 

Personally I've not used the gate. I use the Volume
CV for filter cutoff, and the Pitch for oscillator
frequency.

I'm quantizing with the Wiard "MiniWave" which rumour
has it will be the Blacet "MiniWave".  Its VERY cool
and I made up my own proms with custom scales. The
default scales are OK, but you music folk will realize
that dorian, lydian, etc... are all just the same
eight notes in a row.. starting at a different point.

My modified box has a 12 position rotary switch to set
tonic note... then the MiniWave sets Major, Minor,
etc.

Its very hard to make it look hard to play live. A
wiggle of the fingers and all the speed-metal kids
have
to go home !!!

Would you mind sharing that EPROM? I have a nice ZIF socket on my 
MiniWave just crying out for an alternate ROM!

Crap, you guys with the Miniwaves are having all the fun.  And, here I am
building an excel spreadsheet for panel orders. :(

Then what is the Wave software that is available for the MiniWave?  It will
also work with the Doepfer A-112 I believe.
