Subject: [korgpolyex] Poly fans - need a little help

Hi Poly fans,

I need a little help to confirm that the joystick code I've written is
working correctly. Since I don't have a working original Poly 800, I
need to understand the pitch bend range.

The pitch bend range I've implemented in my new joystick bend code is
between 7 and 8 semitones up or down. This means that on a Poly 800
with the bend pot at maximum, I am able to bend C up to somewhere
between G and A and I am able to bend down C down to just slightly
below F.

I need to know if that is how the original Poly 800 bends.

Can someone help me confirm this? It would be very much appreciated.

Regardless, the original pitch bend joystick function is almost (or is
exactly) as the original Poly 800 was. Next I move on to the VCF MG
and DCO MG (Y joystick) functions.

Once those are as close to the original as possible, I will move onto
new joystick controllers. Woohoo!

Mike.

Hi Poly fans,


I need to know if that is how the original Poly 800 bends.

Can someone help me confirm this? It would be very much appreciated.

LOL - very droll indeed.

It seems very strange indeed that the MK2 would slide a full octave
down when the same circuitry is used for bend in the MK1 and the
EX800. And since I don't have a MK2, I can't play around with it to
see how it works differently.

The main thing is that I needed to make sure that my bend code that I
needed to write for the Poly 800 works as the original does. And it
does, so we're in good shape there.

Although reading through the MK2 service manual I realize that I have
one feature still to go to finish the complete integration of
everything that the Poly 800 does into my kit that was based on the
EX800. That missed feature is the sequencer sending MIDI TX on channel
2. The EX800 doesn't send MIDI from it's sequencer but I think the
Poly 800 does. So I have to implement that.

Mike.
