MATRIXSYNTH-C on Hiatus
Hi everyone. I've decided to put MATRIXSYNTH-C on hiatus for the time being. My focus has always been on the gear here on MATRIXSYNTH and submissions for C have only been trickling in as focus has moved to The MATRIXSYNTH Lounge. If you'd like to share your music and check out what others are doing be sure to check out the lounge.
Roland Jupiter-8 with MD-8 MIDI DCB Interface SN 413260
via this auction
SN 413260
"'Throughout the production of the JP-8 there were several changes. Starting at serial #171700 the D/A converter on the Interface board was changed from 12-bit to 14-bit. This change was made mainly to improve tuning stability. The problem with the 12-bit digital-to-analog converter on the original JP-8 is that it could cause the autotune to be inaccurate in some instances. Some say to avoid these early JP-8's while others say they haven't experienced tuning problems. Starting at serial #242750 the LEDs of the display were changed to brighter ones. Starting at serial #282880 the JP-8 came standard with a DCB port. These newer JP-8's may be referred to as JP-8A's. DCB, or Digital Control Bus, was Roland's pre-MIDI interface that allowed the JP-8 to talk to other DCB enabled hardware, such as the Roland MC4 and MC8 microcomposers. Previous JP-8's had the option of having the OC-8 retrofit installed to give it DCB capability.' Check out more info from Wiki : http://en.wikipedia.org/wiki/Roland_Jupiter-8"
Roland MC 202 with Original Box & Kenton CV Upgrade Kit

the MC 202 unit- everything works great.
Original box (including Styrofoam padding)
Original power supply
Original Operators Manual

Kenton 4 socket upgrade (not installed) - I ordered this, but never installed it. If you are handy with soldering it's an easy install, or you could get your tech to install it.
More info on the cv/gate upgrade (from Kenton)-
The MC-202 does have CV and Gate input sockets already fitted, which can be used with a CV converter, however these input sockets are not satisfactory in most cases. Firstly they are designed so that you can enter information into its internal sequencer using an external keyboard (or indeed, the CV converter), the significance of this is that it quantises the notes into discrete steps, in other words if you try and do a pitchbend, you will end up with the notes going up in semitones only, not smoothly. This isn`t a fault with the CV converter, but the action of the quantising process in the MC-202. Secondly, the fact that the note is quantised, sent to the internal sequencer & then played by the sequencer circuitry, means that the response is fairly slow doing it this way. Thirdly, you are limited to the note range that the sequencer can play. For the above reasons, we recommend that you have your MC–202 fitted with additional CV, Gate, filter & portamento sockets. We can supply a kit to fit your MC–202 with proper CV Gate and, filter and portamento input sockets which do not suffer from the above limitations."

Slow-Scan TV meets Monotribe
"By matching the Monotribe's LFO speed to the sync speed of an SSTV capture program, I am able to generate abstract imagery, and by controlling the pitch, LFO speed and filter cutoff / resonance, I have rudimentary control over the colors and shapes generated.
