Your Fingertips Create New Sounds

OscDrax is an innovative iOS waveform synthesizer that enables professional sound design through intuitive touch controls. Simply draw waveforms with your finger to instantly create original tones. Combine four independent tracks to build complex, rich soundscapes.

Unleash Creativity with the Waveform Editor
Our waveform drawing system maximizes the potential of touchscreen technology. With 512-point high resolution, accurately reproduce any waveform you imagine. Classic waveforms like sine, triangle, square, and sawtooth are also available at a single tap. Designed for everyone from beginners to professionals.

### 4/5 — Loves it, but ..

*2026-01-18*

this app is super cool, not to mention that i got it for .49 cents
However, unfortunately it does not function w any kind of audiobus or DAW capabilities, but .. i had to find a way to use all the lovely (sometimes unlovely but i love that) sounds so i play it w a screen recorder, save it to my camera roll and open the audio in Koala. otherwise, Bravo
