The most important thing will be the power supply! If you're going for 5 VCO's it will need to be VERY stable, otherwise tuning and scaling will be all over the place... trust me, I have 9 ARP based VCO's in my system, and trying to keep them all in tune is a nightmare. Next project - A 4amp dual r...

Other than both being 6 voices there is really nothing in common with them. So yeah they do complement each other well...

If you want an original P-600 DAC I have them.

I have the Drumtraks 0.5 ROM if you want it...

What ROM version is your Drumtraks (it should be labeled on the chip)?

No I was using both your boards.

I have the IR3R05 voice chip in stock if you need one.

There's also the Mungo Juno-6 MIDI kit which I think was only $100. I have one but haven't installed it yet...

Hmm, no support for the JX-10 with the updated ROM?

MIDIDesigner is another app for making your own controllers by the way...

You might want to install sockets for the IR3109s so you can swap them around to see if any are bad...

If they are going for more than CS-5s or CS-10s that it just silly... h**l for $599 you can get a CS-15 on ebay. It's much more limited and doesn't use the same voice chips as the rest of the CS series and doesn't sound nearly as good to me. I used to have a CS-01mkI, bought it for $50, sold it for ...
