The Modstar Oscillation module is a top notch VCO designed by design guru Tim Caswell. Taking inspiration from the circuits of classic Arp and Oberheim hardware and the wave shaping circuits of the 2nd Generation Minimoog Model D, the result is a hybrid beauty!
The Modstar VCO has such a great sound that you'll immediately notice the difference. As such a fundamental part of your modular setup, getting the basic sound right is a priority. The Modstar Oscillation module has such a wide range of tones, you would be forgiven to think that the raw tone was part of a bigger setup. With everything from a massive sub that you feel rattling round your chest to the sweet highs at the top, this oscillator has got you covered.
Designer Tim Caswell notes,
"What's nice about our OSCILLATION stunner is that the waveforms are DC-coupled, so they keep their shape even at sub-Hz speeds. The outputs are also buffered, so the amplitude is independent of the load they are driving. The waveform levels on some modern eurorack OSCs are often all different, and they vary depending if they go into the mixer or directly to the filter!"
This design of direct circuitry coupling without in-line capacitors frees up the whole frequency spectrum and ensures a near identical response for years to come as it protects the transistors. A perfect balance which makes this gorgous sounding oscillator one of the best of the best!
Specifications
Potentiometer Potential
Three attenuation, and three attenuverter pots control the FREQUENCY, TUNE, PW CV IN, PUSLE WIDTH, FM CV IN, and SUB LEVEL, delivering smooth, detailed, and complex expression.
Switch it Up
NORMAL and LOW RANGE - wide sweeping audio frequencies, or clicks (respectively) for creating a rhythmic pulse or sweep; SINE, TRI, SAW, SQR - your friendly waveform on and offs.
Patch it Up
Eleven patch points: 1 V/O, FM IN, WAVE MIX, SYNC IN, PW IN, SUB OUT, SINE OUT, TRI OUT, SAW OUT, RAMP OUT, SQR OUT direct the deepest manipulation.

How much is my shipping?
Shipping costs are calculated automatically at checkout. Simply add items to your cart and proceed to the checkout page, where you'll see the available shipping options and their prices. VAT at the applicable rate for your country will also be displayed at checkout.
European Union orders:
- Standard shipping is free on orders over €100. Express shipping is available on orders over €100, and free on orders over €400.
Poland orders:
- Standard shipping is free on orders over 250 PLN. Express shipping is free on orders over 500 PLN.
What about local taxes?
By default prices on the site include sales tax at 20%. The precise sales tax rate for your country will be calculated at checkout.
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.

| Sweden | 3–5 |
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.
