Description:
Introduce new actions to control the horizontal zoom factor (e.g. 0.5x, 1x, 2x, 4x, 8x) of the sequencer timeline using widgets such as buttons, dials, faders, or knobs.
Problem:
Currently, there's no way to programmatically control the sequencer timeline's horizontal scale. Users are limited to pinch gestures or manual UI interaction. In live performance or controller-based setups, there's a strong need to control the sequencer zoom factor hands-free or via external hardware.
Proposed Solution:
Add the following widget actions to control the sequencer's horizontal zoom factor:
  1. Set Specific Zoom Factor:
Use buttons or stepper dials to jump directly to a defined zoom factor (e.g. 1x, 2x, 8x).
  1. Control Zoom Factor via Range Mapping:
Use knobs or faders to adjust the zoom factor smoothly across a defined range.
Example: map 0%–100% of a fader or knob to zoom factor values between 0.5x and 8x.
These values should correspond to the existing visual scaling behavior of the sequencer timeline and allow for intuitive, musically aligned navigation.
Benefits:
  • Enables precise control of timeline scale during live performance or editing.
  • Makes Loopy Pro more accessible in touchless or controller-driven environments.
  • Improves efficiency when navigating complex sequences.
  • Enhances integration with external MIDI controllers and custom UIs.
Examples:
  • A knob widget ranges from 0.5x (overview) to 8x (detailed view), giving smooth control over the sequencer’s horizontal scale.
  • A button instantly resets the view to 1x for a centered editing workflow.
  • A foot controller fader lets a performer zoom in on the fly without touching the screen.
