1、 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
2、 its 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 wasnt entirely successful in a lot of ways. First of all it requires a separate midi to control voltage converter that cost more that t
3、he 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 oscill
4、ators, one MS20 2-pole resonate VCF , two LM13600 VCAs and one MS10 type LFO. The MM-pros 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. M

NOTE: that the pad for the anode (the side without the stripe) of D4 does not go to ground as it should. Do not use this pad, instead connect it to the lead coming off the anode of D20 it does go t
23、o ground as it should. Install IC sockets in all spaces marked for ICs. NOTE: DO NOT INSTALL THE ICS YET. Install all Jumpers (15) except the one thats next to R62 and the jumper next to PAD-C2 and R85. These two jumpers will be installed after the midi converter is working. They supply power to the
24、 analog sections on the board. As long as these are dis-connected the VCOs, filter, amps and egs will not work. Install all of the capacitors. Mono Cap Ceramic Cap Electrolytic Cap Polyester Cap I have been using strips of 0.1 break-away pcb pin headers for all pads on recent projects. This gives a
25、convent place to solder to or connect your test probe. The Mouser # for a 36 contact long tail pin strip header is.517-834- 03-36 $0.83ea. I urge you to use these instead of wiring directly to the board. The tail is long enough so there is still room to solder even if the pin is placed through the u
26、nder side of the board. Install the trimmers and DIP switch S2. You can use less expensive trimmers for T4,7 T1,2,3,5,6 T4 & T7 Install all transistors except Q29, and the Q13/Q14, Q16/Q17, Q22/Q23, Q25/Q26 pairs. NOTE: the pin-out on the pcboard for the N-Fets is for 2N3819s. NOTE: If you substitut

28、 PAD-A and the large ground PAD Before you plug it in be ready to up-plug it in case of smoke or heat. Get your meter and set it to AC Volts. Plug the transformer in. Nothing should smoke or be hot to the touch. Measure the AC voltage on PAD-A and ground. It should be between 12 and 14VAC Set your m
29、eter to DC Volts. Attach the negative lead to ground and measure the voltage on pin-4 of the socket for U11. It should be about -12VDC . Measure the voltage on pin-8 of the socket for U11. It should be about +12VDC . Measure the voltage on pin-7 of the socket for U4. It should be about +5VDC . Unplu

Connect a 5-pin DIN Jack (midi-in) to Pads E and F. Connect a midi keyboard set to midi channel 1 to the
31、 midi-in jack. Make sure all switches on S2 are off. Plug the transformer in. If you have a scope. Measure Pins 15 and 16 of U5. You should see the PIC clock running at about 10MHz.

35、 and Setup The Q16/Q17 and Q25/Q26 pairs need to be thermally connected. NOTE: Q16/Q17 and Q25/Q26 are dual NPNs and may be replaced with 2SC1583s or other dual NPNs. Place a dab of heat-sink compound on the face of one transistor. Place the other flat to flat and secure together with heat-shrink tu
36、bing. Solder to the board bending the leads so there is no pressure on the pair to separate. The Q13/Q14 pair are PNP/NPN and should be thermally connected with 1K tempco resistor R48. Place a dab of heat-sink compound on the face of one transistor. Place the other transistor flat to flat and secure
37、 together with heat-shrink tubing. Solder to the board bending the leads so there is no pressure on the pair to separate. Once soldered cut the heat-shrink off. Solder R48 into place so that the body of the resistor is in contact with the transistor pair. Then using a larger size of heat-shrink secu
38、re both transistors and resistor Install the jumper next to R62 and the jumper next to PAD-C2 and R85. These two jumpers supply power to the analog sections on the board. As long as these are dis-connected the VCOs, filter, amps and egs will not work. Run a jumper from PAD-I (keyboard pitch-out) to
39、PAD-T (vco pitch-in) Replace the PIC (U5), DAC (U6) and MUX (U9) Connect a 5-pin DIN Jack (midi-in) to Pads E and F. Connect a midi keyboard set to midi channel 1 to the midi-in jack. Make sure all switches on S2 are off. Connect your scope or monitor to VCO1 PAD-B2 Plug the transformer in. You shou
40、ld see/hear a sawtooth wave. The pitch should change when you play the midi keyboard. Adjust trimmer T3 until the pitch is one octave apart when playing the C3-C4 octave on the keyboard Connect your scope or monitor to VCO1 PAD-X Adjust trimmer T4 until you see/hear a 50% square wave. It will sound
41、smoothest. Connect your scope or monitor to VCO2 PAD-V Adjust trimmer T6 until the pitch is one octave apart when playing the C3-C4 octave on the keyboard Connect your scope or monitor to VCO2 PAD-C2 Adjust trimmer T7 until you see/hear a 25% square wave. Just a little past the smooth sound. This wi
42、ll keep the oscillators from locking to the same beat frequency and canceling each other out. Unplug the transformer. Remove the PIC (U5), DAC (U6) and MUX (U9) place them back in protective foam. Disconnect the midi-jack Wiring and Assembly Options Once the initial setup is complete you are ready t
43、o finish the wiring before fine tuning the circuit. The wiring instructions are for the normalized stomp box style synthesizer. The Modular option is self-descriptive and presented at the end of this manual. Midi Wiring Row 1 Wiring Row 2 Wiring NOTE: I reversed the common wire for the Attack/Decay
44、Pot when I drew this. This will cause the pots to function in reverse. Connect the common to the center and right terminal, connect the wire from the board to the left terminal. Row 3 Wiring NOTE: I reversed the common wire for the Attack/Decay Pot when I drew this. This will cause the pots to funct
45、ion in reverse. Connect the common to the center and right terminal, connect the wire from the board to the left terminal. Final Assembly and Setup Now is a good time to install and line up the spacers you intend to use to suspend the board over the controls. The best way Ive come up with is to atta
46、ch the spacers to the board. Put a drop of model paint or ink on the end and then position it in place. The paint will mark the inside of the case so you can drill the holes in the right place. There are two test traces on the board break the trace between the large PAD-A and the two small pads conn
47、ected to PAD-B. This allows the power switch to turn the unit off. Break the trace between PAD-A2 and PAD-S. This allows the Sync switch to disconnect VCO2 from pitch-bend CV for Sync sweeps.
