| 1.5×8 | Tall fader (more precision) |
| 2×6 | Wide fader (easier to grab) |

| 6×1.5 | Standard horizontal |
| 8×1.5 | Wide horizontal (more precision) |
When to Use Sliders
✅ Use sliders for:
- Volume/level controls (vertical)
- Pan controls (horizontal)
- Channel strip designs (rows of vertical faders)
- When showing precise position matters
❌ Consider knobs instead when:
- Space is limited (knobs are more compact)
- Rotation metaphor is more natural
- You have many parameters
Vertical vs Horizontal
Vertical Sliders
- Natural for: Volume, level, gain
- Movement: Up = more, Down = less
- Use case: Channel strips, mixer layouts
Horizontal Sliders
- Natural for: Pan, balance, left-right
- Movement: Right = more, Left = less
- Use case: Stereo controls, timelines
Tips
Mixer-Style Layouts
Group vertical sliders for console feel:
- Equal spacing between sliders
- Same height for all sliders
- Labels below each slider
- Consider vintage style for warmth
Pan Controls
Use horizontal slider with:
bipolar: truefillFromCenter: true- Center position clearly marked
Fill From Center
Enable fillFromCenter for:
- Pan controls (shows L/R deviation)
- Bipolar parameters
- Any “centered” parameter
The track fills from center toward current value.

Slider vs Knob Decision
| Factor | Use Slider | Use Knob |
|---|---|---|
| Space | Have room | Limited space |
| Parameter | Volume, pan | Most others |
| Layout | Channel strip | General |
| Quantity | Few sliders | Many parameters |
| Metaphor | Linear (fader) | Rotary (dial) |
Most plugins use more knobs than sliders. Sliders are typically reserved for volume/pan or mixer-style interfaces.
