Description:
Introduce a Scrubber Widget that enables expressive, real-time control over clip playback position — inspired by the tactile interface of the iOS app
Samplr
. The widget should support both single-finger scrubbing and an advanced multi-finger mode that allows gesture-based selection and playback.
Problem:
Loopy Pro currently lacks an interactive surface to scrub through a clip's waveform in real time. This limits creative manipulation techniques like scratching, granular looping, pitch-like movements, and gestural expression. While playhead actions exist, they don’t offer the immediacy, precision, and tactile feel of a scrub-based interface — especially one designed for multiple fingers.
Proposed Solution:
Create a
Scrubber Widget
with the following capabilities:
### 🔹 Basic Scrubbing Features:
  • Touch or MIDI control to drag the playhead within a clip’s waveform
  • Bi-directional scrubbing (forward/backward)
  • Option to scrub while holding playback (loop-locked) or while paused
  • Playback can optionally follow the finger in real time or be quantized
  • Audio preview on touch-down or continuous playback during scrubbing
  • Optional pitch/time stretching for speed-variable scrub
  • Assignable to MIDI CCs, XY pads, or widgets
### 🔸 Multi-Finger “Samplr-Style” Mode:
  • One finger to
    define a region
    (start and end points)
  • Second finger to
    scrub within that region
    , playing only the selected part
  • Region remains fixed while user scrubs dynamically within it
  • Ideal for slicing, glitching, ambient textures, granular gestures
  • Also useful in clip-based live performance with looping control per region
### 🔧 Additional Features:
  • Adjustable zoom and waveform scaling
  • Toggle for snap-to-grid vs. freehand positioning
  • Visual feedback for loop region and playhead
  • Compatible with both audio clips and resampled material
  • Full support for clip-layer interaction (if layers are visible/editable)
Benefits:
  • Unlocks expressive, hands-on control similar to Samplr and other gesture-based audio tools
  • Supports experimental, live-looping, and remix workflows
  • Great for performers using iPads with touch, as well as MIDI/hardware controllers
  • Adds a dynamic way to interact with loops beyond static triggering or playhead jumping
  • Enhances visual and physical engagement with sound in real time
Examples:
  • Loop a vocal phrase and use two fingers to isolate and rhythmically scrub one syllable
  • Use a ribbon controller or MIDI CC to sweep playback across a texture in sync
  • Scrub backward through a reversed reverb tail for sound design
  • Define a short slice in a drum loop and repeatedly scrub it live for glitch FX
