How to use this tool
Getting Started

Or drag & drop a .json file onto the drop zone.

Create a blank playlist from scratch with a custom name.

Snippet Parameters

0.1 – 10.0 s
Ramp-up time from minimum to maximum intensity.

0.1 – 10.0 s
Time spent at peak intensity before falling.
Fall (s)
0.1 – 10.0 s
Ramp-down time from maximum back to minimum intensity.
Rest (s)
0.1 – 10.0 s

Freq (Hz)

Pulse frequency. Low = rumbly/deep; high = smooth/intense. CH1 controls this — CH2 follows.
Intensity Low
20 – 80 µs
Minimum pulse width — the baseline sensation during Rest and transitions.
Intensity High
90 – 150 µs
Maximum pulse width — the peak sensation during Hold. The gap between Low and High defines the intensity range.
