Monophonic Analog Modular Synthesizer

This is the prototype of a modular synthesizer, which Gerd and his collegue Tino have built in 2008 - only to see the difficulty to build a MIDI controlled modular synthesizer.

The following modular based on the project YuSynth (Synthesizer Do It Yourself).

Modifications were done on the MIDI interface, the Patch module and the ADSR modules.

Main parameter:

- 1 V/Oct
- Monophonic
- 19" width, 10 HE, 230 V AC
- 91 1/4 TRS
- 42 Knobs
- 13 Modules

3 VCO:
- Frequency, Fine Tune, Pulsewidth, PWM, Sinus, Triangle, Sawtooth, Square

2 Envelope Generators
- ADSR

1 Mixer
- 3 Channels

1 Sample & Hold Generator
- Slew Rate, Sample Rate, Noise Generator (White/Pink), Random

1 Lowpass Filter
- Cutoff, Emphasis, 2x Input Level

1 Patchfield
- 4x In, 12x Out

1 LFO
- Rate, FM Level, Sinus, Triangle, Saw, Ramp, Square

1 Amplifier
- 2x Audio In
- 2x Audio Out
- 2x Control In
- Master Volume, CH1 Volume, CH2 Volume

1 MIDI-CV Interface
- MIDI IN, 4x CV, 6x Gate

1 Power Supply
- +/- 15 V DC

Modular System Sound Demos

Remarks:

- Some sounds were supported by external reverb or delay.

- All sounds & tracks arranged and recorded with Steinberg Cubase 5.

- Sequencer MIDI data by KORG Z1.

- All files are mp3 formatted with 160 kBit/s at best quality.
