Pittsburgh Modular System 10 Synthesizer


The Pittsburgh Modular System 10 Synthesizer offers direct access to a wide array of modern, analog monosynth sounds. Without a single patch cable, floor shaking bass and aggressive leads are just a few knob tweaks away. 
Plugging in a few patch cables opens the Pittsburgh Modular System 10 Synthesizer to complex experimentation by offering unlimited control over both the modulation and audio signal paths. The full functionality of the Waveforms Oscillator, Lopass Gate, LFO, Envelope Generator, VCA, Midi, Mixer, and Outputs can be split apart and used as standalone synthesizer modules. All of the elements of a classic voltage controlled, modular synthesizer are available as an open, patchable, modern synth.

The System 10 Synthesizer features a complex waveforms oscillator. Standard triangle, square, and saw waves are available alongside a sub oscillator and our new blade wave. The blade wave is a rich, modulatable saw that can be controlled in several unique ways.

The System 10 Synthesizer also features our new Lopass Gate. The Lopass Gate uses a highly tuned set of vactrols to produce everything from natural sounding filter sweeps and res’d out piercing leads to organic percussion. The Lopass Gate has 3 modes of operation: Low pass filter, VCA, and lopass gate. In lopass gate mode, the filter combines the features of both the low pass filter and VCA to produce a harmonically rich, intricate sound.

System 10 Components 

(Complete, Fully Patchable, 2nd Generation Semi-Modular Synthesizer Voice)

Wired for instant access to classic tones without needing a single patch cable, the Synthesizer Box is a modern, complete semi-modular, monophonic synthesizer module. The Synthesizer Box is 100% analog and 100% Eurorack compatible with a complete set of patch points able to override the internal audio and CV signal paths.The Synthesizer Box was designed to be the core of any modular system. Each major component is fully patchable and can function independent to the rest of the module. This allows the functionality of the Waveforms Oscillator, Lopass Gate, LFO, Envelope Generator, and VCA to be split apart and used like standalone modules.

• Full Range, Complex Waveform Oscillator
• Oscillator Waveform Mixer
• Voltage Controlled Multi-Mode Lowpass Gate
• Wide Range Low Frequency Oscillator
• Glide Control for Portamento Effects
• ADSR Envelope Generator
• High Quality, Linear Response, Voltage Controlled Amplifier

(Multifunction Utility Module)

• 3 Channel Mixer
• 2 Passive Multiples


The Mix Mult is a multifunction utility module. The module combines three important functions into a single module. A high quality three channel mixer and/or attenuator and two sets of passive multiples.

The mixer/attenuator section functions as a flexible, low-noise three channel mixer and/or attenuator for audio and cv that can be used in several ways. Patching into the output of channel 1 or 2 will remove that channel from the mixer circuit and turn the channel into an independent passive signal attenuator. Channel 3 can not be removed from the mixer circuit, however if channel 1 and 2 are all being used as attenuators, channel 3 is the only input remaining in the mixer allowing it to be used as a buffered attenuator. The mixer knobs are wired with a logarithmic volume curve that is tuned for use with audio but it will work with CV as well.

The bottom of the module contains two sets of passive multiples. Patching a signal into one of the multiple jacks will split the signal to the remaining two jacks. allowing a single audio or CV signal to be used in two places at once.

(Triple Mode MIDI to CV Converter)

The Midi2 converts standard midi note messages into the analog control voltages used by modular synthesizers.  This allows a modular synthesizer to be controlled by a midi keyboard, sequencer, or DAW.

The two sets of Gate (GT) outputs can be used to trigger envelope generators by providing a voltage of +5v.  The Control Voltage (CV) outputs produce precisely 1volt per octave over a range of 10 octaves.  Control Voltage outputs (CV1 and CV2) respond to pitch bend control messages without any additional patching.

The midi channel is assigned based on the first midi note is received. The two lights on the Midi2 module will change from solid, to blinking, to off. This indicates a midi channel has been assigned and the module is ready to use.

The Midi2 module has 3 distinct modes of operation:

Monophonic – Monophonic mode works great when using a modular as a single voice synthesizer. Gate2 and CV2 outputs mirror the outputs of Gate1 and CV1. Monophonic mode retriggers the gate with each new note played. To change this response to the classic trigger gate mode press C3 when assigning the midi channel.

 Duophonic – The Midi2 module uses the two sets of Gate and CV outputs to allow two notes to be played simultaneously. The first midi note is sent to the Gate1 and CV1 outputs and the second is sent to the Gate2 and CV2 outputs. Duophonic mode is perfect when working with a two voice modular synthesizer.

Dual Monophonic – Gate 2 and CV2 outputs are controlled by a different midi channel than the Gate 1 and CV 1 Outputs.  Dual Monophonc mode allows a modular to be controlled by two separate sets of midi data.  This mode works well when using a modular as two single voice synthesizers.


The simplest way to get sound out of a modular. Outs is a dual independent output module featuring a stereo 1/4″ headphone amplifier output and dual mono 1/4″ line level outputs.

Left and Right inputs are available. If only the left input is used, it is sent to both the Left and Right outputs
