Barton BMC001 Dual Quantizer (Euro)
Barton Dual Quantizer, rev 6 PCBs – Eurorack format, 6hp, Clarke Robinson panel design.
Documentation here: BMC001 Dual Quantizer
This circuit takes a continuously variable dc voltage and outputs only voltages related to each other musically, using the 1v/octave standard. It utilizes a preprogrammed PIC which is included with purchase of a PCB. It is has a very low parts count, requires no calibration, and is small enough to be used either as a seperate synth module or as a daughter board to be attached to the input of an oscillator or output of a sequencer/s&h/other cv generator.
This module (and the panel and kit) require the use of 3 PCBs, (2 quantiser PCBs share the LM317 adaptor PCB )
The kit and assembled module include the 7805-to-LM317 modification for improved accuracy.
IMPORTANT: set the trimmer to full CCW before powering the unit; otherwise you will FRY the PIC.
The pcb + ic sets includes 2 main pcbs, 2 PICs and 1x7805 to LM317 adapter PCB.
The panel+ic bundle includes eurorack panel, 2 main pcbs, 2 PICs and 1 X 7805 to LM317 adapter PCB.
Orders for a single PCB and PIC do NOT include a 7805 adaptor PCB.
These kits and assembled modules are offered on demand, click the link to learn more.
