Yeah, I think that might be doable. I look into it.

Mike can You write what new functions will be implemented in p800?
There are so many posts about this mod, that my brain is slowly out of
stock ;) haha :D

Yes, since I used the EX800 code and added the Poly specific functions
into it, the bend range parameter 87 is already available.

All I need to do is migrate it into the extended parameters and it
will be available on a per patch basis. I am thinking that since no
one would probably ever use a bend range value of 1 that I will use
that to determine if the global bend range is used on a patch or the
actual extended parameter. So if you set the bend range to zero in the
extended parameter then there's no bend at all. If you set it to 1
then the global bend range becomes the bend range that will apply. And
if you select anything from 2 to 64 then the extended bend range
applies. That would give you maximum flexibility.

What do you think?

BTW, if we do this then we could rewire the bend pot for something else.

Mike.

Radek,

Here they are so far:

1) flash EEPROM software upgrade capability (as I develop new software
you will all be able to download it and continue upgrading your Poly
and EX800's as long as we keep developing new features).
2) Sysex single patch dump send and receive.
3) All notes off panic button.
4) Omni On, Off or Auto on power up.
5) Keyboard MIDI TX channel selection (1-16 or no MIDI TX).
6) Joystick MIDI TX channel selection (1-16 or no MIDI TX).
7) Local keyboard control on/off.
8) Local joystick control on/off.
9) Extended playing range on/off (increases the playing range by two
octaves while ignoring the parameters 11 and 21).
10) Cascade mode (for when you have two Poly's or a Poly and an EX800.
One unit plays odd notes and the other plays evens).
11) Cascade sync mode (the master unit sends sysex patch dumps to the
slave as well as setting the Poly mode and program changes. This
ensures that your slave unit plays exactly the same sounds as the master).
12) Portamento mono mode with slide rate parameter stored per patch
(accessed by pressing the poly key twice).
13) MIDI controllers for setting Poly, Hold, Chord and Portamento.
14) a second LFO is now used to control the VCF MG.
15) Both LFO1 and LFO2 now have triangle wave, reverse triangle and
square wave parameters.
16) Both LFO1 and LFO2 now have free running modes (so that they don't
reset on note down events. They just keep cycling).
17) LFO2 for VCF has random mode.
18) Poly mode is stored and recalled with patches.
19) MIDI controllers implemented for LFO1 rate, VCF cutoff and
resonance depth.
20) Bend depth stored per patch.

That's it so far.

Hi Poly fans,

just a quick note that I've updated my web pages that describe the
progress of the hardware/software upgrade kit.

The biggest change is that I've simplified the proposed new features
page and added a page for features that are completed.

This way, you can all keep up to date on what I propose to add to the
software and what is already done.

Note that I just added tremolo to the list of proposed new features.

Check the pages out at:

Mike.

Mike,

my commentary comes little bit later... And I will mention only negative
points :-)

Will you use some temporary edit buffer for this function? It would be great
just for quick going thru the patches from some librarian without necessity
to write them into the memory. Only if I will decide to use some patch, I
can write it into the selected memory location.

That means one octave more up and one octave more down?

I suppose this function can be switched On or Off, sometimes it could have
sense to play the same music with different sounds, just for the effect or
fun (of course lot of such combinations have no use).

There's no Poly key on EX800, how you will implement this?

> 13) MIDI controllers for setting Poly, Hold, Chord and Portamento.

Poly can be implemented rather as a Poly/Unison selector, so I would call it
Unison - in Poly the instrument will work normally, in Unison it will play
in unison (monophonically with all oscillators detuned if possible, detune
depth should be changeable).

> 14) a second LFO is now used to control the VCF MG.

I don't understand this. You mean one LFO will modulate another LFO? Here
you write "VCF MG" but below under 17 you use a term "LFO2 for VCF", I'm
confused what you mean.

So LFO1 is for DCO, LFO2 for VCF?

That means Poly/Unison status?

Will you use for this Non registered parameters as implemented in the other
instruments (Yamaha, Roland...)? Standard setting is:

- LFO rate: CC 99 = 1, CC 98 = 8
- VCF Cutoff: CC 99 = 1, CC 98 = 32
- VCF Resonance: CC 99 = 1, CC 98 = 33

For last two you can use more simple way:
- VCF Cutoff: CC 74
- VCF Resonance: CC 71

I would prefer this.

IMHO this can be used mainly as an effect, because combination of square
waves in different octaves approximates  missing sawtooth wave (in fact it's
only staircase simulation). It's a lot of years I used 800, I don't remember
well, how exactly it works and haven't Owner's manual right now at my hand.
Maybe in the sawtooth mode it's not possible to switch off individual square
octaves??? Or because they have decreasing volume in higher octaves effect
of switching on/off them will be not to hear well?

But it can have some sense in square mode.

Hi, Mike,

Thank you for your detailed answers.

Even so, that's quite perfect, more than expected! Would it be possible to
do such changes when the other music MIDI data are sent to the instrument? I
mean in real time when instrument will perform music? It would be
interesting  to change parameters "on fly" and go continously from one sound
to the other, kind of morphing...

So if I understand well, total range of the instrument is the same, but we
can use it without switching feet setting (16, 8, 4)?

Understand.

That's great.

Why? Each LFO has different waveforms or some other parameter? I suppose
yes, because if they are the same, this possibility will have no practical
effect.

Which controllers have you used for this?

Perfect, now I have found that GM2 standard uses CC 76 for Vibrato rate.

Q: Would it be possible to do such changes when the other music MIDI
data are sent to the instrument? I mean in real time when instrument
will perform music? It would be interesting to change parameters "on
fly" and go continously from one sound to the other, kind of morphing...

A: any parameter that exists now that does not reset the voices will
be able to be changed on the fly. Parameters (for example: octave
change) that reset the voices will also be reset when sysex (or
controller) is received via MIDI. For example VCF, resonance,
harmonics, EG parameters etc do NOT reset voices so they can be
changed while voices are working.

Mike.

Alan and all newcomers to the list,

To all of the newcomers, I'm sure I speak for all of us in wishing you
all a hearty welcome!

If you would like more detailed information on the kit that will soon
be made available, you can go to:

http://patrioticduo.tripod.com/korgpoly800ex800mkiii/index.html 

There you will find the list of new features as well as my blog of the
progress being made. Eventually, this is also where the kit
construction and installation instructions will be. The trickiest part
of the installation of the kit will be removing the original EPROM
socket and one of the 16 pin chips. Other than that, the kit will be
an easy bolt on addition. I haven't worked out the exact price yet but
it will be somewhere close to $100 USD.

I originally started this project because my wife told me to find a
hobby that has no chance of ever making any money so that I would then
not convert the hobby into a money making enterprise. The irony is
that I've just about done exactly that. One of these days I am going
to get back to writing some music (that was the original idea). But in
the meantime, silly me went poking around in the Poly 800 and realized
I could probably improve it significantly. So here we are 14 months
later and just about to put the kit onto the market.

I must say, I have had such an enjoyable time working on this project.
I've learned so much about the complexities of controlling sound
generation within the confines of software. I have also come to
appreciate and respect the engineers who put the Poly 800 together
back in 1983. It is quite remarkable how they created such a great
design. I have also "met" a great bunch of people on this list.
Without their constant input and feedback I would not have made such
rapid progress nor would I have dreamed up some of the features that
are now part of the software.

I still have to wonder at my level of sanity for having decided to
take this on. But now that I've come this far I just have to finish.

Speaking of which, I finished another feature today. You can now
reverse the delay mode on both LFO's. So now you can modulate until
the delay expires and then stop modulation or you can wait for the
timer to expire and then modulate (as in the original). This means you
can modulate the DCO or VCF for a brief moment at note on and then
drop off the MG when the LFO delay expires.

And, this email is getting way too long but also, I sometimes wonder
if I am talking too much on this list. If anyone is feeling like I
talk too much about the kit just let me know and I'll tone it down a bit.

Yes, the idea is to provide MIDI CC's for every parameter. Some will
be able to be changed in real time while notes are on. Some will reset
the voices. I am thinking that I'll use CC's for those that do not
reset the voices and use SYSEX for those that do.

Mike.

Thanks! :)
