Dor - samples on the SP-1200

Roland MC-202

via this auction

"This is an analog synthesizer/sequencer. It sounds very much like the TB-303 and SH-101 bass synths. It has a very evolved form of TB-303 like programming (more like the MC-4) and SH-101 like controls of the VCO, VCF, VCA, LFO, Envelope and Mixer sections. The LCD display is a great feature too.

The MC-202 was sort of a next-generation TB-303. So the idea was to program sequence/patterns into it internally which would give you those 303 basslines that we've come to love. You can control it externally by hooking up a MID-CV/Gate converter. Then you basically have yourself an SH-101!

The sequencer is actually a 2-channel CV/gate sequencer, with both channels being capable of driving a separate external synth. It's a very useful unit, also, for its DINsync capabilities; it can receive on one port, and send over two, and also can 'split' DINsync to branch a sync signal out to multiple devices.

This machine is best for those who want to get 303-like patterns (it has accent just like the 303) and basslines with an SH-101 sound. If you can handle programming the notes into its sequencer you can have a lot of fun.

The MC202 is a sequencer and simple monophonic synth with 32 buttons arranged like a small keyboard (F-C).

The monosynth is similar to the SH-101. The VCO is based around the ever-so-popular Curtis 3340 chip and features a slider switch for octave (2', 4', 8', 16'), a slider for pulse width, and one for modulation (LFO) amount. The VCO outputs a square/pulse wave, a sawtooth wave, and a sub-oscillator which are mixed together in the "Source Mixer" section. The sub-oscillator is switchable between a square wave 1 octave down, a square wave 2 octaves down, and a pulse wave 3 octaves down. There are knobs which control fine tune and portamento. The VCF section has a slider for cutoff frequency and resonance. There is a slider for each of its control sources: envelope, LFO, and keyboard. The VCA can be controlled by a simple gate or the Envelope. The envelope is an ADSR with a slider for each stage.

The sequencer is quite powerful for its time. The MC-202 features a large (for the time) LCD display, upon which all the sequencing editing is displayed. The two available sequences can be played simultaneously using the CV/gate outputs to control another sequencer. The sequences can have a combined total of 2729 events. Sequences can be entered in real time via the pushbutton keyboard or via another keyboard using the CV/gate inputs. This feature has a negative side, though. Since all incoming CV/gate signals are routed through the microprocessor, there is a bit of a lag when the MC-202 is played by a another keyboard or a MIDI-to-CV device. The Sequences can also be programmed using step-time, setting a separate pitch and duration for each note. Also programmable in a sequence is accent and portamento. Accent works the same as in the TB-303, with an accent amount knob that can be adjusted in real time as the sequence is playing. The speed of the sequence is also controlled by a knob.

The back panel has a sync input and two sync outputs, a tape interface for saving and loading sequences, CV/gate inputs and two CV/gate outputs (one for each sequence), a headphone jack, and a main output jack.

The MC-202 came out at a time when the synthesizer market was just starting to impliment MIDI. After MIDI became an accepted standard, sequencers such as the MC-202, using the old-style CV/gate interface, quickly lost popularity and died away."

All MOTM CD

via sir_dss on the Matrixsynth Forum. Reposting here after checking with sir_dss.

"Hi,
I'm new to the board and have been reading the Matrixsynth blog for over a year now. I do hope it's alright to post this here but I cant think of a better place!

I just released a CD of music from my MOTM system. No other synths were involved but there are some Blacet and Cyndustries modules making guest appearances(all MOTM format though...). NO MODERN COMPUTER TRICKS WERE INVOLVED!

It's about 34 minutes long and covers many moods and styles that I've explored on my Modular Synth. From soundtrack(ish) to Suicide(ish), noise/glitch to French pop...and even as Paul would say "Bug Music". It is 11 tracks with a proper mastering job done at the studio built by The Mars Volta and crew.

This is the link...It is ppm13.

I am also starting a residency this Sunday the 9 to the 13th at Family, this art, music, and underground culture bookstore in Los Angeles.

http://www.familylosangeles.com

I will be setting up and playing my MOTM system in the late afternoon for a few hours everyday trying to develop new music and hopefully be "entertaining"! The director Lance Bangs(David Cross, Nirvana,Sonic Youth, YYY's...) is going to be filming a feature with me for VICE TV at some point during the stay.

If you are in LA come by and hang/nerd out with the me and my MOTM!

Thanks,

Inside electronic instruments


via Inverse Room:

"I just put up a small set on flickr of the innards of various synths. I'll try to add to it from time to time. So far there's the Yamaha SY2, Yamaha YC-25D, and a Russian handclapper stompbox. Also a homemade Triwave Picogenerator.

Pictured:
"The Yamaha SY2 oscillator and filter modules. Apparently the filter is the same as the one in the enormous GX1 monster synth, and thus the same as the one in the MOTM GX1 filter. Old Crow actually reverse-engineered this filter for MOTM by dissolving the material it's potted in--see his page on the project at www.cs80.com/ne_proj.html."

MOOG Moogerfooger Murf

images via this auction

"The MF-105 MuRF is a new and unique effect designed by Bob Moog. MuRF is short for Multiple Resonance Filter Array. The MuRF provides sequenced filter effects that have not been heard before!

MuRF stands for "Multiple Resonance Filter Array". What this means is the MuRF has 8 filters - their levels are controlled by 8 sliders. It looks like a graphic eq, but the sound of the filters are very different: warm and resonant.

What is really unique is the ability to animate the levels of the 8 filters in up to 24 preset patterns. The rate of the patterns can be set by a knob, expression pedal, or plug a footswitch into the tap tempo input to match the rate to the tempo of your song. Rhythmic variations can be created by adjusting the levels of the filters. The Envelope control sets the shape of the modulation, which can be set for percolating techno rhythmic modulation or shimmering timbral morphing. Other controls include Input Drive, Output Level and Wet/Dry Mix.

MuRF shares the musician-oriented features that are common to all Moogerfoogers. All the audio processing is 100% genuine analog, for warm, fat sound quality. Any line level or instrument level audio signal may be processed. Wide-ranging player parameters may be controlled from the panel knobs as well as from expression pedals or CV-compatible analog synthesis instruments. Components are rugged and long lasting, to withstand the rigors of stage and studio. The MuRF is housed in the classic Moogerfooger "double-wedge" enclosure that may be used on a table or on the floor.

More information plus lots of nice audio examples at the Moog Site
