Purpose

Smooth applies configurable slew to any control signal, eliminating the stair-stepping of raw MIDI CCs and adding performance-grade feel. Separate attack and release rates let fast transients punch through while releases fade gracefully.

TouchDesigner Use

Place Smooth after MIDI Learn, MIDI Note, Control Remap, or any control_f32_v1 source. Adjust the smoothing time to taste. Wire the smoothed output into instrument or effect parameters. Works on all channels of the input stream.

Inputs And Outputs

• Input 0: in — control_f32_v1 (required). The control signal to smooth.
• Output 0: out — control_f32_v1. The smoothed signal.

Main Controls

• Smoothms — Global smooth time in milliseconds. 0 = passthrough. Default 5 ms.
• Attackms — Separate attack slew time. -1 = use Smoothms. When set, rising values use this rate.
• Releasems — Separate release slew time. -1 = use Smoothms. When set, falling values use this rate.
• Curve — Smoothing character: linear (faster perceived response), exp (standard exponential, default), or log (slower approach with faster initial movement).

Notes

• Processes at audio rate for sub-sample smooth transitions.
• On first frame, state initializes to the input value to avoid startup glitches.
• Automatically expands to handle up to 64 channels if the input stream grows.
• Reveal channels show the effective smooth, attack, and release times in milliseconds.
