Product Description

The Mantis is a collaboration between the late Chris Huggett (Gnat, WASP, OSCar) and PWM (Paul Whittington). In development over the final period of his life, Chris threw everything he could into the Mantis. Although incomplete when he passed away, he handed his part of the project over to Paul to continue and to see what, if anything, could be made of it — he really was so humble in his work! PWM, with the support of Chris' estate, think this synthesiser is totally amazing and deserves to be born into the world for everyone to enjoy.

Oscillators

The OSCs are generated at boot-up using complex mathematics. They run on a DSP chip that gives ultimate stability and control without compromising the unique sound. This is what makes the synth a hybrid, but don't be fooled —everything after that through the mixer, gain staging and the filter is analogue.

VCF

The filter is a multi-mode state variable VCA filter with overdrive. It is built using the SSI2164 chip in a special configuration designed by Chris Huggett. There are two filters — one for each analogue signal path. They can be combined in series or parallel, and used with the width control and width modulation to create that distinctive sound only heard on the OSCar.

FX

The Mantis has two simple digital effects: reverb and chorus. Reverb has a time and level adjustment but also a high and low pass filter that can be switched in to limit unwanted lower mud and/or higher bouncy twinkles!

Envelopes


Mantis has 2 ADSR envelopes, but each has an additional 'Sustain Fall' parameter and negative and positive velocity modulation level hardwired for convenience. Sustain Fall allows you to create a drop before release even while a key is held, for greater sound design possibilities. Each envelope can also be put into repeat mode to act as a pseudo LFO if you wish.

VCA

The gain staging on Mantis is, of course, all analogue and is run through the SSI2164 VCAs — PWM have a few of them in the design! The signal is actually twice amplified to ensure that the overdriven sound is warm and clips naturally.
