USB audio

On a computer’s USB, FRIZZ is a sound card, called FrizZ, alongside its MIDI: 2 channels each way, 48 kHz, 24 bit, as USB Audio Class 1, which macOS, Windows, Linux and iPadOS know without a driver.

• From FRIZZ to the computer: the master as it is before VOLUME, so a recording doesn’t change with the knob: the line out’s signal at full VOLUME, before the safety limiter. Pick FrizZ as an input in the DAW or the recording app.
• From the computer to FRIZZ: the input’s third source, USB. Pick FrizZ as an output, and on the settings page USB with the upper F# (blue). Like AUX it has its own input gain, monitoring and effects, and the looper records it.

Set the computer (or the DAW) to 48 kHz for the best quality. FRIZZ runs at 48 kHz only; a computer set to another rate converts on its side, which costs it a little quality and latency. The computer follows FRIZZ’s own clock, both ways, so nothing drifts or clicks over a long take.

USB audio on or off: on the settings page, with USB the source, SHIFT + upper F# switches it; while you hold SHIFT, the upper F# shows it (lit on, dim off). It’s on out of the box, and saved. Switching it, FRIZZ leaves USB for a moment and comes back with the other setup: MIDI over USB is gone for about a second, then back, and a Companion upload running ends. Off, FRIZZ is MIDI and the card drive alone: for a computer that has trouble with the sound card, or that you don’t want to offer one. With USB audio off, USB stays a source you can pick, dimly blue, and silent. While the card is lent to the computer, USB audio can’t be switched: the upper F# blinks red 3 times.
