Subject: Re: [korgpolyex] Welcome Poly 800 newcomers

From: Alan Currall <alan@...>

Hiya Mike,
Thanks for the full and informative answer and the link to your blog. It's a truly fascinating project and there's no way you talk about it too much on the list. Surely if there's ever gonna be a place for us to talk endlessly about the Poly/Ex 800 in ways which would bore the pants off any 'normal' person, then this is it.

I'm now following the progress of the MkIII mod with great interest and really looking forward to seeing the final outcome. Please add me to you, no doubt, long list of advance orders.
Cheers,
Alan

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/ korgpoly800ex800 mkiii/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.
