USB Recording – Help Center

Tutorial Video

For Windows users, please download and install the ASIO driver for REACTOR from the Downloads page.

Overview

No external audio interface needed - REACTOR's built-in USB audio includes the full signal chain (amp and effects), functioning as a 48kHz/24-bit audio interface.

Spec	Value
Sample Rate	48 kHz
Bit Depth	24-bit
Channels	1 In × 2 Out

Important Notes

No power output: The USB port does not provide charging capability.
Wet signal only: USB recording captures the fully processed signal. The amp and cab simulation cannot be bypassed in the REACTOR app, so you will always record the "wet" tone.
Dual Mono output: The 1 In × 2 Out configuration outputs dual mono (identical signal on both channels), which is standard for guitar recording — not true stereo.
