Description:
Introduce a DJ- or sampler-style “Slicer” mode that divides a clip into rhythmic slices and allows instant triggering of those slices — either via a grid, MIDI controller, or touch input — similar to features found in tools like the Korg Volca Sample, Roland SP-series, or Serato-style slicers.
Problem:
Loopy Pro currently lacks a dedicated slicer interface for rhythmic or pitch-based clip triggering. While clips can be manually trimmed or edited, there’s no native way to divide a loop into steps or beat slices and jump between them in real time. This limits live remixing, finger drumming, and creative beat manipulation — especially for users coming from DJ or sampler hardware.
Proposed Solution:
Add a
Slicer Mode
or
Slicer Widget
with the following capabilities:
✅
Core Features:
  • Divide a clip into N slices (based on grid: 1/4, 1/8, 1/16, custom)
  • Trigger slices manually via:
- Touch (grid layout)
- MIDI pad controller
- Key or widget-based input
  • Slices can either:
- Jump playback instantly
- Retrigger as one-shots
- Sustain while held ("Hold-to-Play")
✅
Volca Sample–Style “Step Jump” Mode:
  • Hold a step to jump playback instantly to that slice
  • Release returns to original timeline (optional)
  • Behavior: momentary jump vs. latch
  • Compatible with looping playback or free-running
✅
Additional Options (as requested in comments):
  • Slice-to-MIDI (assign slices to specific MIDI notes)
  • Per-slice FX, reverse, or pitch control
  • Sequence slices in the Step Sequencer
  • Map slices to individual AUv3 chains (optional advanced use)
Benefits:
  • Enables performance styles like beat juggling, stuttering, slice remixing
  • Opens new creative workflows for DJs, finger drummers, loop-based performers
  • Bridges the gap between clip looping and classic sampler-style triggering
  • Makes Loopy Pro more competitive with hardware samplers and iOS tools like Koala, Samplr, Blocs Wave
Examples:
  • Load a breakbeat, slice into 8 steps, trigger each slice live via MIDI pads
  • Use a Volca-style jump to step 5, then release to resume loop from original timeline
  • Play a sliced vocal phrase chromatically via MIDI mapping
  • Trigger rapid-fire slices in sync with quantization for glitchy textures

Original Post:
Slicer version that mashes up features from a DJ style slicer (as in Serato or Djay Pro) and Volca Sample's step jump feature.
– Retrigger selected slice at adjustable timings (1, 1/2, 1/4, 1/8, etc)
– Retrigger selected slices in sequence (as in Volca Sample Step Jump)
– Hold function to keep slices selected after fingers lift off
