Description & Specs

This project is a collaboration between the late Chris Huggett (Gnat, WASP, OSCar) and PWM (Paul Whittington). In development over the last 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! We at 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, and we know Chris would be really proud too!

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 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 - we have a few of them in the design! The signal is actually twice amplified to ensure the overdriven sound is warm and clips naturally.

We’re all musicians here at Chicago Music Exchange and we want you to love the gear you get from us. We understand that sometimes you get a piece of gear that doesn’t work out for you. That’s why we offer an easy return policy to take the stress out of purchasing from us.

If you decide you'd like to return an item, please contact your Sales Rep, chat us, or give us a call.

If you placed your order on Amazon or eBay, we advise issuing the return request from your account on the platform of purchase - our Customer Service team will process a refund upon receipt of the item(s).

Most new items may be returned within 30 days of delivery and most vintage & used items may be returned within 3 days of delivery for a full refund, exchange, or store credit. Please pack the product safely for the journey back to us. If the product was shipped for free, the charge will be deducted from refund, unless the reason for the return is outside normal circumstances.

Please contact us as soon as possible if your order was received incorrectly, damaged, or defective. Most times we will give you an RA number (Return Authorization). Why is that number important? This will allow us to speed up the process of the return.

We reserve the right to charge a restocking fee based on the return condition. Some items we just can’t take back for returns, due to a one time function like strings or drums heads and other times it’s not sanitary to do so with microphones or harmonicas. If you aren’t sure if what you bought falls into a category like this, call us (773) 525-7773!

We strive to get your return processed quickly. Most of the time we have it done within two business days. Funds going back to credit cards usually takes two to four business days. CME strives to make sure all customers are happy with their experience. It is our priority to provide great service along with great gear. We always want to be helpful, and open to your feedback.
