Volume & Gate Control

Randomization & Variation

Randomize patterns, volumes, and gate lengths independently with weighted bias control. Set per-row probabilities, lock rows to protect them, and auto-randomize each cycle for ever-evolving sequences.

Simple Setup. Endless Possibilities.

Interlock uses two plugins that work together. Place an Main sequencer on one track, then drop an RX on each track you want to control. Each RX automatically appears as a row in the Main's sequencer grid — then you simply draw your pattern.

Run up to 16 independent Mains in a single session. One for drums, one for synths, one for vocals — each with its own pattern, timing, and RX units. Build as many interlocking layers as your project needs in realtime.

  • Add a Main plugin to your control track
  • Drop an RX on each track you want in the sequence
  • Draw your pattern, hit play, and listen

Built By a Musician, For Musicians

Interlock was born out of frustration. I was spending hours slicing up audio to create mosaics by hand — and every time I wanted to change a sound, I had to start over. I wanted a tool that handled the mechanical side, so I could focus on what actually matters: the music.

I'm Ajja — musician since age nine, self-taught coder since the early 90s, and recording and worldwide touring artist for over 20 years. Interlock is the first of many tools from Ajja Sonic.
