16 VOICE DEMON CORE OSCILLATOR
The catch of our Demon Core Oscillator is in a new innovation called the MDCO (Multiperiod Digitally Controlled Oscillator) which allows a single analog oscillator core to form multiple simultaneous waves with pitch and phase control. In practice this means 16 analog voices which can be controlled separately.
The sonic gravy is found in the fine tuning of the voices. They can be set in strict digital tuning, be statically detuned (spread) or set to drift (Core Stability). Or both. The spread control takes us from a brutalist digital cityscape to super saw planet while the core stability ranges from vintage DCO synthesizers to a broken and misbehaving vintage VCO. On the middle ground of both controls the sound resembles that of the old warm VCO designs of the 80’s (which we are very fond of).
The basic building blocks are saw and pulse waves (with PWM) but more complex waveforms can be created using two or more unison waves and triggering the phase sync via the sync trigger input. Simultaneous unison waves in the same phase increase the amplitude but when slightly detuned they generate strange harmonics and form unusual waveforms. If more voices are used, spread is opened slightly and the sync trigger input is used with gate signal, the phase sync acts like a decay envelope producing flanging effect. This can be used for massive bass synthesizer sounds.
All of the voices can be configured in different depths of unison and octave stack. Up to 6 octaves are supported. The 16 voices are spread evenly between the octaves.
Since we know the precise tuning of the waves the master tuning can be accurately set in A440 across 6 octaves via a tuning LED. This makes the module handy for practical applications requiring accurate pitch. The 1V/Oct pitch control is calibrated to high precision. A bipolar linear FM with a attenuator controls the master pitch in conjunction with the 1V/oct input.
While the Demon Core Oscillator stores megatons of energy in itself, it can be boosted to maximum yield by attaching the Demon Core Expander to it. Check it out over here.

Do you ship to my country?
We ship to all EU member states from our warehouse in Warsaw, Poland. Add an item to your cart and enter your country and postcode to see the available shipping options and prices for your location. If you have any questions about shipping to your country, drop us an email at info@signalsounds.eu and we'll be happy to help.
Shipping methods
All EU orders are shipped via UPS. We offer two service levels:
- UPS Standard – our default shipping option. Delivery times vary by country (see estimated delivery times below).
- UPS Express Saver – next business day delivery to most EU destinations.
Each product page shows the estimated delivery time for your location, so you'll always know what to expect before you order.
Estimated delivery times (Standard shipping)
The times below are estimates in working days from dispatch, based on UPS Standard service. Express Saver delivers by the next business day to most destinations.

These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.
Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
