Buffer size
Buffer size in Settings offers requests of 32, 64, 128, 256 or 512 frames. Smaller values mean lower latency but use more CPU and leave less processing headroom. Start at 128, check stability, then try 64 and 32. If audio breaks up, increase the buffer and compare with a lower QUALITY / CPU setting on NAM blocks or fewer effects.

- Choose 32 / 64 / 128 / 256 / 512 under Buffer size. This example uses 64.
- If a small buffer causes dropouts, raise it and compare with the same rig.

Requested versus actual
The device may negotiate a different buffer. Check the actual values in sample rate / buffer and RT (round-trip latency) at the right of the bottom bar. Total latency includes conversion, the operating system, effects such as NAM or pitch processing and the FX Loop round trip, as well as buffering.
Note One fixed latency figure cannot describe every setup.
Input channels and outputs
Under Audio input, Settings shows the channel counts and sample rate reported by the device. Under Input channels choose the IN each of PATH A and PATH B listens to, and leave PATH B OFF when you do not use it. FX Loop and Backing Track Output have limited choices on devices with only OUT 1/2. Each Path’s output connectors are chosen at OUT at the end of the chain, not in Settings. Tap the ⓘ beside a section title to unfold explanations of its rows.

- Below Audio input, the device reports 2 in · 2 out · 48kHz.
- An orange note says FX Loop cannot be turned on because this interface has only OUT 1/2.
- For the same reason, Backing Track Output offers only OUT 1/2.
- Tap the ⓘ beside a section title to unfold its explanations.

Preparing and Resume
Preparation status appears beside PATH A at launch or during device changes. Automatic startup preparation differs from Audio Ready after an interruption that waits for your confirmation.
Caution Audio Ready presents Resume; check the connection and monitor level before resuming.
Without an interface the output is muted, and Continue editing in the notice lets you keep editing without sound. Buffer changes can briefly reconfigure audio.
Long sessions
Caution Rehearse long enough on the actual device, interface and rig to check heat and stability.
Power, hubs, cables and background tasks also matter. Interfaces that report the same channel count can still map headphone outputs differently. Looper buffers are reserved up front, but only what you record uses memory.
