J74 StepLocker is a sequencing and modulation device for Ableton Live (Max for Live) based on the concept of parameter locking, whereby parameter settings can be associated with each sequencer step.

The work-flow in StepLocker is very simple: choose one or more steps in the sequencer, select a parameter in Ableton Live, set its value and lock it. You can do this for any parameter, in any device, in any track of Live.

On top of this StepLocker offers also classic step sequencer features such as playback manipulation (step numbers, random step order), value interpolation, randomization and (post-locking) editing (copy, paste, erase).

Feature set:

  • Up to 64 steps modulator with parameter locks.
  • Any parameter, in any device, in any track of Ableton Live can be locked.
  • User interface based on simple actions: just click, set, lock and sequence.
  • No routing or long menu's involved.
  • Different modulation styles (Impulse/Hold, Gliding).
  • Real time sequencing controls: step number count, step duration, random playback order.
  • Post-locking editing features: free editing of every recorded lock, randomization, shift values up/down, mute values, copy and paste sections.
  • Possibility of recording the modulation as Session clip automation or Arrangement automation.
  • Device state saved with the Ableton Live project.

StepLocker is a Max for Live device for Ableton Live 9 and higher.
