I just got this little beauty and I'm finding my efforts to locate a manual are becoming thwarted... I have tested the modules, but I'd really like to get the vintage keyboard functional as well... I understand that these keyboards can perform polyphonically? The keyboard ties into an 8780 module... Can anyone help me out?

Also... I'd love to find some of those pin jacks. Anyone know where they can be found?

Hi Chris,
Join the Yahoo Paia Group at:
http://launch.groups.yahoo.com/group/PAiASynth/

ALL the manuals are in the "files" section".
But, you have to be a member of the group to access the manuals.

I have several digital 8782 keyboards. Although I haven't used them in a long long while, they are fun to play with. I would like to mention that there was a linear D/A in addition to the 8780 equally tempered D/A.
Paia never sold a kit for the linear D/A. IIRC, It was in an article in one
of the Polyphonys. Hmmm...I think the article was in one of the "Frendly Stories....." articles (?) Again, see the "files" section....

All of this info (and MUCH more)is in the "files" section of the Yahoo Paia Group. Good luck with your new PAIA.

Hello Chris.

I've copied links below to topics in Q&A section of PAiA Talk which you might find useful.

PAiA 9700K MIDI2CV8, 2720 4700 series modulars, FatMan

Using 4700 and 2720 series modulars

Where do I start with this P4700J

Over in the Technical Bulletins section, there is:

2720 and 4700 series patch cords, FatMan interface, insight

For polyphonic operation, you need the 8781 QuASH with the 8700 computer/controller running Poly 1.0 or MUS1, and really, a cabinet of modules for each voice.

If your goal is to sound more than one note, it might be best to just go with a newer keyboard instrument with on-board sounds and a MIDI connector and use a converter or FatMan to get cv and triggering for operating/slaving the module cabinet as a layered voice.

God bless you all for your help! I actually joined that yahoo group Saturday!

I spent the weekend playing with this thing. I had some minor repairs (the balanced modulator had a blown cap and diode) and tweaking. I used my Korg MS-20 to trigger it.

Still tho... Crazy fun! The Synth gods have smiled upon me!

I'm finding my bottom octave to be 3 octaves higher than the next two on the synthesizer. I'm also finding that the scan rate is accompanied with that annoying click. Is the scaling of the keyboard a function of the programming? Is there a program guide for that interface?

I am stymied by the truly expansive forethought given all of these modules.

I tore into the reverb unit last weekend and got it going. Seriously; what a well thought out set-up. Kudos to you guys!

It's a digitally scanned keyboard. Not analog. EACH note has a specific binary code. Sounds like you are missing a "bit". Check the diode matrix for the keyboard. Read "Frendly Stories About Computers/Synthesizers" about how the whole digital-to-music thing works. Specifically, pages 23-28 cover the digitally scanned keyboard matrix. But, you should read the entire series to learn how the D-2-A and keyboard interface together.
Good Luck!! T 8-)
