A Synth for Versatile Experimental Sound Design

SynthieCat is a Max for Live matrix synthesizer. The EMS Synthi A model was its inspiration, which debuted in May 1971 and was made famous by the likes of Pink Floyd, Aphex Twin, and many more.

Even though classic bass and lead sounds are possible, don’t expect a traditional synth. This machine is designed for sound design and experimentation. It’s no surprise the EMS Synthi A found its way early into the toolkit of the BBC Radiophonic Workshop, or was used by the psychedelic spacerock band Hawkwind in the early 1970s.

At its heart, a 16×16 matrix allows you to connect signals and modulators. Just like the original, SynthieCat features three oscillators with a very wide frequency range. This allows to use the oscillators in the low frequency region as well.

A ring modulator, noise generator, built-in reverb and the ability to process external signals makes this device an extremely versatile sound generator and processor.

Like the original suitcase version, SynthieCat also features a simple but fun built in MIDI sequencer with variable speed control. You can record a note pattern to then play it back continuously.

Each of the three oscillators’ frequency can follow incoming MIDI notes, simply by clicking the Toggle (keyboard icon) on the left. A MIDI note will also trigger the envelope shaper – which again is different from a classic ADSR curve.

Additionally, SynthieCat can be sidechained to other tracks in the Live Set. This way it can function as an effect for audio sources of any kind.
