Helium AUv3 MIDI Sequencer

1. Download and install Helium, then open it as an AUv3 plugin inside your iOS host app or launch the standalone if available. 2. Create a new project, add a track, and assign a MIDI output to your target synth or MIDI device. 3. Use the step editor to enter notes, adjust step length, velocity, and per-step CC values to craft patterns. 4. Start playback and enable MIDI clock sync to lock Helium to your host or external tempo, then tweak patterns in real time for live performance. 5. Save patterns and presets, export MIDI clips or route sequences to other apps/devices for arrangement and further production.
