Loopy Pro Clip Slicer controlled by Midi

Hello,

I would like to control the Clip Slicer using MIDI so that it can randomly trigger clips and eventually change their pitch.

I’ve tried using Fugue Machine to achieve this, but since it’s difficult to know exactly which MIDI notes Fugue Machine is sending, it becomes tricky to map each pad of the Clip Slicer with the MIDI learn function.

Do you have any suggestions for a better solution using another app and technique?

    You could manually set up the bindings rather than midi learn.

    Instead of using the clip slicer, you could make the clip a midi target and use slice rather than pitch mode.

    This approach is excellent—especially in Pitched Notes mode, where Fugue Machine lets me control the pitch creatively.
    My main concern is that it always triggers from the beginning of the clip, which limits variety.
    Is there a way to trigger different parts of the clip randomly, rather than always starting from the beginning?
    Any ideas for achieving truly random clip triggering?

    In slice mode, different notes trigger different slices. In pitched notes mode, the start point is always the same.

    Thank you for your reply.

    I'm still working on randomizing the Clip Slicer.
    Using MIDI learn mapping isn’t ideal for this task since random MIDI notes are constantly triggered, and manually mapping each button on the Clip Slicer is quite tedious.
    Could you recommend an app or technique to simplify this?

    Additionally, I’m trying to figure out how to record a MIDI clip to trigger the Clip Slicer, but I haven’t found a way to do so yet.

    Regarding using a MIDI clip to trigger an audio clip as an instrument, it works very quickly,
    but I don’t understand how transient slices behave in the piano roll.
    Long MIDI notes don’t extend the playback time of the audio clip, and I’m unclear on how MIDI note placement in the piano roll relates to the audio clip’s playhead movement.

    Manually mapping of the clip slicer shouldn’t take more than 30 seconds per pad. You can use the midi learn interface but don’t have any midi playing. Enter midi learn mode. Tap a slicer pad. Tap where it says listening for events. Manually set the trigger. Move on to the next slicer pad.

    If you want to trigger the slicer from a midi clip, set the midi source to the midi color you will be using.

    When you trigger slices, middle c (note 60) triggers the lowest slice and successive white notes trigger successive slices. (The note numbers wrap)

    Record yourself counting to see how the midi notes map.

    Triggered slices stay within the slice boundary
