A few useful answers
Before you dive in.
Do I need to know modular synthesis?
No. Start with a factory patch or use Random to build a playable system. Explore one knob or cable at a time; Undo lets you step back.
Does it work inside my DAW?
Download the Mac or Windows VST3 preview for a VST3-compatible DAW, including Ableton Live. One desktop licence covers the plug-in and standalone app. The standalone app also works without a DAW. Logic Pro requires Audio Units and cannot load this VST3.
What happens after seven days?
Audio stops until you activate a licence or your one-time extension. Your patches stay intact. Get seven more days by verifying your email and providing the Machine ID from the LICENCE panel. This does not subscribe you to marketing emails.
How do I activate my purchase?
After Stripe checkout, paste your Machine ID from the app's LICENCE panel into the key page. Your key is shown and emailed to you. Paste it back into LICENCE. Activation guide →
Can I use it on iPhone or iPad?
The Touch edition is in testing and isn't available for public purchase yet. The direct desktop licence covers Mac and Windows; the Apple edition is a separate purchase. See the Touch development preview →
Made by a musician who missed his modular
“The best sessions were the ones where the instrument had ideas of its own.”
I fell in love with West Coast modular systems, then missed mine after selling the hardware. I built WestCoastSynth to bring back that sense of discovery—with instant new patches, visible signals, and the freedom to save every good accident.
