Roland MC-4 Step Sequencer Micro Composer MC4

via this auction

"This unit can sync to or generate DIN sync, so syncing it up to a laptop, TR-808, TR-909 or TR-606 is no problem at all with the proper DIN converters. I used it with a Roland SBX-10 to sync to Ableton so I could capture the loops I was making with the MC-4 sequencing my Arp 2600 and SH-101."

Update: Another PPG Wave 2.2 Typo and some Tips

see the second update in this post. Again remember to check posts for red Updates throughout the day. The red stands out and should be easy to spot scrolling quickly down the page. Always click on the Older Post link at the bottom of each page and do the same. Each new day starts with a red date header, so it's easy to see where new days start as well.

Remember you can submit stuff via my contact info on the bottom right, or in the comments of any post. The rule is you have to be able to ID the synth in a post. Posts are about the synth first, music second, so if you want to promote your stuff in a vid or the like, be sure to show your synth. Also I try to spread things out so the site doesn't get overrun by one person, so send me your best and I'll link to the rest.

Finally, auction posts are welcome. Anything goes on MATRIXSYNTH-B and good pics, rare items, interesting facts and the like go up here on MATRIXSYNTH.

Update: and of course check out the forum's WTB and WTS for more.

Please post PPG comments in the PPG post linked above. Comments on the tips and what goes up are welcome here.

RADCASTle Documentation

You might remember the RADCASTle from this video. Docs and images are up here.

RADCASTle stands for "Really Awesome Digitally Controlled Analog Synthesis Tool, limited edition"

"The analog boards were purchased from Ray Wilson of Music From Outer Space. The team developed custom boards to interface the various analog synth boards with a PIC microcontroller through digital-to-analog converters."

MOOG SOURCE With Sync In

via this auction

"16 programmable presets are available. The unusual thing about this synth is that instead of the common "Cassette Interface" on the back of most of the Sources, this one has a 5-pin jack that says SYNC IN. I have read that this was a feature that made the Source usable with some Roland equipment of the same era. I've never used this feature but I noticed it was unusual. I couldn't find any mention of the Sync In feature in the manual, it only talks about the models with the Cassette Interface."


Anyone know more about the Sync In?

Update via Kelly in the comments: "There were three eras of Sources. the earliest does not have DIN Sync. Then there is a "retrofit" era where it was added at the factory but without any silkscreening, so labels were affixed to the outlets. Then the final run that the silkscreening in black (like the one pictured)."

via Zero: "It's a DIN Sync jack making it compatible with Roland Drum machines of the era. I think it was 24ppq."

via Analogika: "The Sync input was standard on all later Sources (it's mentioned in my manual as an addendum from February 9, 1983). There was a period were the cassette input was re-assigned to sync in via factory retrofit, and a sticker applied to the rear of the case.

It's a rather bizarre semi-solution.

The arpeggiator needs a clock signal in order to run, but the actual notes are triggered by pulses to the "reset" in.

The sequencer will run in sync to the DIN 24 signal, AFAIK - I must confess I've never tried it, and my Source is currently cased up for live performance. :-)

Update2: you can find a doc on the drum interface for the Source here.
