Digital D1: Hybrid Synth

Beautiful Hybrid Virtual Analog/PCM Synthesizer

“Breathtaking Presets, right out-of-the box”


500 mb of additional sounds with every copy of Digital D1!


Recommended if you like classic digital synths like the D-50, JD-990, 01/W, Wavestation, and more**

This app does not sample ANY of those synths. It is a modern re-imagining. New sounds. New synthesis. Perfect for a modern production with a retro feel.


Effects and sound engine modules have been Open-sourced. Use the code in your apps for free. No license required. It is our gift to you. The DSP code building-blocks are available in AudioKit.


On the roadmap:
AUv3 Plugin. Use this app as a full-screen plugin in GarageBand, AUM, BeatMaker 3, and more.

AUv3 support is coming. It will be a free upgrade.

Or, you can just wait and buy Digital D1 when AUv3 is added.
No pressure. We’re cool. You’re cool. Everyone’s cool with Digital D1!
