I did sell a board, to Greg M. Did your Poly Six vacation in CA? -------------------------------------------- On Fri, 12/18/15, James Matthew Smith jmsmatthewsmith@gmail.com [PolySix] <PolySix@yahoogroups.com> wrote:

Well that's good news.
Please pardon my ignorance of your device this is for, in
fact I think my old polysix was midi modd'ed by you Bob
so i should know this already (i'd bought it from
someone who had it done by you).. But for what product of
yours are you referring to? You have a replacement IC6 or a
whole board?

You are incorrect in saying that noone has ever
extracted the Poly Six key assigner code.
As I mentioned in an earlier post, my PIC code is a direct
port of that code. I take the 8049 instruction
and map it to the equivalent PIC instruction. I did have
to add a little delay in a few places as the PIC is
much faster, but aside from that it's the same. I also
added MIDI note on and off, but that was a pretty
small change.

Thanks Florian,I'm
actually expecting the DIY arp to be a difficult
situation
but one worth pursuing, albeit with some patience and no
guarantee it'll end up working.My setup
has
changed and i'm gearing up to abandon computers and
midi
altogether. To play the arp, i'll be wanting to create
a
miniature keyboard using dozens of small momentary
buttons,
and then (and i know this might be tough) have the output
of
the arp able to go to monosynth cv/gate. It would of
course
be nice to be able to have the output be switchable
between
V/oct and H/V, but V/oct would be preferred if only one.
However is that's accomplished, external conversion
would be possible at that point.
When i used the arp on the polysix,
i almost always just set the synth into "monosynth
mode" which was just by using the chord function
for
just one note. Then it would only ever trigger the same
voice over and over. So this would be the goal for the
diy
arp circuit, to create a purely trigger/cv/gate
situation
but only ever for one voice at output. I don't even
have
a poly synth anymore.
And as for the tuubutec arp
situation, and others, i'm pretty sure that the IC6
program information has never been extracted by anyone.
So
all of the arps out there are approximations, probably
including the korg plugin. They may be close, and
probably
all awesome in their own regards. And maybe i'm naive
to
think that the original is superior since i haven't
actually used the Kiwi/Tubbu/etc versions and they
definitely have wonderfully committed designers behind
them.
But it's worth trying to resurrect an original since
i'm already in love with the darn thing. call me a
romantic.

Hello J,
you are of course right about how wonderful the
arpeggiator
in the P6
is, but still there is the question: what soundgenerator
do
you want to
control with it? You have to rebuild the complete
Voiceboard
including
the VCOs!
The CPU and the D/A converter output a multiplexed
"nearly V/Oct"
voltage without any trimming. If you control a normal
CV-Synth with this
voltage, it will sound like "cats chant"
(german
saying). The trimming
happens within a common exponentiator for all voices and
then is
demulitiplexed as six V/Hz voltages. The VCOs of the P6
are
V/Hz (this
is, why the P6 is that amazing stable in relative tune).
If you want the P6-Arpeggiator and want it to send
MIDI-NOtes, then get
the tubbutec CPU for the P6 (https://tubbutec.de/modypoly/).
You may use
it nearly standalone and it will send the Arpeggio via
MIDI-Out and(!)
will read the notes from MIDI-In.
