"This is an analog module that allows for uniform detuning and offseting of control voltages. It has a CV input and an offset input. It has outputs for the offset being applied positively, negatively and double offset applied positively and negatively. When used without the CV input, it can be used as a standalone inverter or fixed gain amplifier."

"This is a PIC based percussion module which is loosely modeled on the hi-hat. It features seperate Decay and Pitch controls for Open/Close modes and a master Shape control which mixes between a linear or logarithmic decay. This module is also compatable with the BMC003X Expander for using external CV for all of it's parameters."

"'1Song' is a simple, microcontroller centered synthesizer module for generative (self composing) music. It both composes the melodies and produces the audio itself, requiring no other modules to make music, but it also features inputs and outputs for timing which help it integrate with other modules in a modular synthesizer system. It can also be built in a stompbox style enclosure without these inputs and outputs and act as a standalone music producer, powered from a 9V battery or power adaptor.
The melodies that '1 Song' produces are not traditional melodies produced from a diatonic scale and using duple or triple meter for rhythms. Instead, it composes by using algorhythms to produce semi-random numbers, and uses these numbers for it's pitch and length a note is held. Notes are held anywhere from 1 to 16 beats, and there are a total of 64 different notes which can be played. The notes are not arranged 12 per octave, but rather as divisions of the highest frequency, the lowest note it produces is 1/64th the frequency of the highest, the second lowest note is 1/63rd, and so on.
The board features PC mounted pots for less wiring, and mounting holes for flexibility in panel layout. There are Eurorack and MOTM power connecters."

"New prototype from Barton Musical Circuits. MWC = Multi-Window Comparator. Sorry for the blur, I'm working in a basement and the light's not great.
In a nutshell, this looks at your input voltage, converts it into a number, then looks that number up on a data table and turns a +5V output on if the table tells it to. It does this 4 times, for 4 different outputs. There are attenuation and offset knobs for conditioning the input signal, write/erase buttons for writing the "on/off" tables, and save/load and bank select switches for saving your tables to the internal EEPROM.
The write/erase buttons could also be replaced by input jacks so you're rhythm generating devices could write the tables. The board has euro/motm power connector pads. The board has 2 pc mounted pots, and it also has 4 mounting holes so people can feel free to create their own layout. I am going to try to offer a Eurorack front panel for this as well.
I will be writing build documentation for this soon. I'll have boards/PICs to offer for this next month, and a set will be $20 plus postage."
"A dry boring demo of the features of a new quantizer module I've designed. More info will be up at www.bartonmusicalcircuits.com after I get it written.
To summarize: Instead of pre-loaded scales/modes, you're using write/erase buttons to create a data table that records all possible outputs, if you saw my MWC demo, this will seem familiar (I actually copy/pasted some of the code).
There are additional controls for: turning the quantizer off, triggering a new sample (it constantly samples when nothing is plugged into this jack), controlling whether the quantizer quantizes above or below the input voltage, a "softness" control which acts like a voltage controlled portamento with fun interactions with the trigger-new-sample control. It can also save two banks of notes onto the internal EEPROM. There is also a bi-polar/positive only switch so it can interact with more voltage sources.
There are input jacks for the quantized signal, a secondary cv (with attenuation pot), external softness cv (with attenuation pot), write and erase jacks for triggering from external sources, trigger-new-sample, and quantize on/off.
Finally, and I didn't get into this on the demo, the board is set up so that the range of the module is adjusted by just a couple of trim pots (an input attenuator and an output amplifier) so individual builders can decide whether they want more range or accuracy. Different people will use this differently so I'll leave it up to them. On this demo I had it set up for 10V range. The table of possible outputs has 1024 parts (because the PIC has a 10-bit ADC), so this gives me 102.4 pitches/octave. At 5V you'd get 204.8 pitches per octave.
This prototype had a few errors on the PCB, so I'm waiting for a revised PCB to show up (should be in the next couple weeks), and if I got all my errors on that, then boards should be available to ship in early to mid January. I think a board/chip combo will be $22. This uses all through hole components, and pc-mounted pots, but has mounting holes so people don't have to use the pc mounted pots. It has euro/motm power connecters and will work with +/-12v or +/-15v with no modification.
I think I'll also be selling a few of these with hand made front panels if anyone thinks this is a cool module but is intimidated by all of the wiring. This is 8HP in euro-rack."
"This is a short vid demontrating the basic functions of Dave Kendall's CMOS based MIDI 2 Clock Converter.
For the patch i use the M2C (controlled by Cubase), my new BinSeq (divider/attenuverter based sequencer), Boogdish's simple Quantizer and my dual X-4046 VCO (Thomas Henry).
For clocking the BinSeq i use the gate out of the M2C, the stop out resets the BinSeq. So each time i stop the Cubase sequencing software the BinSeq gets a reset. When staring the pattern from the beginning, the sequencer is in sync again."
