Inside the JX-8P. I wanted to see which opamps mine uses. Answer: JRC 4558DD’s (that is, the good ones) I’m not sure it really matters that much if they are JRC or Sharp chips, the JX-8P sounds lovely anyway. The JX-10 and MKS-70 use totally different opamps and I want one of those too. The insides are small - bit bigger than an Alpha Juno - and surprisingly neat compared to Korgs of the time but Korgs used more discrete components. I’m not an expert on these things and mostly don’t know what I am looking at it but I am curious.
Useful table of IC’s used in 80’s Roland polysynths (doesn’t mention opamps)
2069 AD sounds like the name of an Italian softcore sexploitation sci-fi movie. This chip is supposed to be a combination filter/VCA chip like that found in the Poly800.
…no more bad jokes…
EDIT: apparently 8 of these chips are found in the DW-8000 and DSS-1, so thats pretty cool. Poly800 only has one of them since it doesn’t have a polyphonic filter - and filter may actually be *after* VCA, similar setup to my Casio HT-700.
I am also wondering if the filter can be modded for real-time tweaking ala the Poly800 mods. I suspect not since there’s no way of tweaking it from the DDD-1 OS controls but I’m a noob with this sort of thing.

The (elusive?) DDD-1 sampling board in all its glory.
It *is* a pretty cool looking little board.

Posted these a while back. Apparently people are still downloading them. Big collection of stuff, I forget if I found it all in one place or not but I remember it took some Googling in the first place. Thanks to whoever posted these anyway.
The patches are great, esp if your Alpha is missing the factory patches and you need to make hoovers. But the Alphas do more than that of course!
Includes a couple editors. I like the PG300EMU best. Works with the Alpha Juno 1 and 2 and also the MKS-50 (with extra stuff!) These are really brilliant little analog synths from Roland, really cool and a good editor makes them about 20% cooler.
Do like very much. Pretty close to a Polysix and I’ve seen Poly800’s go for more than this cost.
The arpeggiator is the same as the Polysix and damn near perfect. No midi on this model but arp has a trigger in. Win. Just what I wanted. Wish the arp was programmable like the DW8000 though.
Envelopes are SSM chips, filter however is a Korg OTA filter similar to those in the later MS-10/20s and the DW8000.
Kinda want a second DW8k. Heavy sumbitch. (So is this one. Only the finest particle board would do for the body.)
LEDs. Oh hells yeah! Technology from the future!
This is fun too. I has a joystik.
