*Excluding the following: Special orders, gift cards, used items, vintage items, open-box items, and clearance items. Qualifying purchase amount must be on one receipt and cannot be combined with promotional coupons. A promo fee, equal to 2% of the amount financed at time of purchase, will be shown as a separate transaction on your billing statement and included in the balance subject to this promo. Any taxes, delivery or other charges included in the amount financed will increase the related promo fee and the required monthly payments. For example, a $950 purchase with $50 in taxes and shipping costs, will be charged a promo fee equal to $20 and $1,020 will be charged to your account. No interest will be charged on the amount financed (including related promo fee), and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the initial total promo purchase amount (including related promo fee) divided by the number of months in the promo period, rounded up to the next whole cent. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period, the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

Any taxes, delivery or other charges included in the amount financed will increase the related promo fee and the required monthly payment. The estimated monthly payment shown (excluding taxes and delivery) equals the amount financed (including related promo fee) divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make your payments by the due date each month, you should pay off this amount financed (including related promo fee) within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this monthly payment will be added to the minimum payment applicable to those balances.

Overview

Duophonic hybrid-analog synthesizer with dual filter, 200 patch memory and full USB-C MIDI control.

The PWM Instruments Mantis Duophonic hybrid-analog synthesizer is a collaboration between the late Chris Huggett (Gnat, WASP, OSCar) and PWM. In development over the last period of his life, Huggett threw everything he could into the Mantis. Although incomplete when he passed away, he handed his part of the project over to Paul Whittington to see what could be made of it.

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; however, everything after that through the mixer, gain staging and the filter is analog.

The Filter is a multi-mode state variable VCA Filter with overdrive. It’s built using the SSI2164 chip in special configuration designed by Chris Huggett. There are two filters—one for each analog 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.

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.
