EFM Mad Mouse Pro - Midi Synthesizer
V1.0 (C) 2001 EFM Synthesizers
Assembly and Setup Manual
The Mad Mouse-Pro is a midi controlled analog synthesizer. It is designed to be built as a small stomp-box sized analog so that it
can be positioned on top of your master midi controller for easy access to it's controls. The Mad Mouse story started in late 1998
when I decided to design a small inexpensive analog synthesizer that could be built for under $50 dollars. I wasn't entirely
successful in a lot of ways. First of all it requires a separate midi to control voltage converter that cost more that the synthesizer did
and I went over budget by about $20 dollars. Still....it was a working analog synthesizer for under $200 dollars and that included
about $100 bucks for the separate midi converter.
The MM-pro contains an on-board midi to cv converter, a +/-12 +5V power supply, two Odyssey type oscillators, one MS20 2-pole
resonate VCF , two LM13600 VCAs and one MS10 type LFO.
The MM-pro's midi converter responds to midi pitch, pitch bend, mod, key-gate and glide-gate. The midi messages are converted
to control voltages. These voltages are used to control the analog sections of the synthesizer.
