VA-1

VA-1 is a focused virtual-analog synthesizer for musicians, producers, and sound designers. One app, one purchase — runs natively on iPhone, iPad, and Mac, and now works as an AUv3 instrument in compatible hosts.

Inspired by the workflow of classic hardware synths, VA-1 keeps playing and sound-shaping on one fast, hands-on panel. Tweak sounds in real time, build sequences, map hardware controls, and open the full effects rack whenever you want deeper shaping.

No subscription. No in-app purchases. No ads. No account required. Buy once, own it.
