Can the Zoom B1 Four’s looper function be synchronized with an external MIDI clock via USB to maintain timing with other devices in a live setup?

No, the Zoom B1 Four’s looper function cannot be synchronized with an external MIDI clock via USB. The B1 Four does not support MIDI clock sync, so it cannot maintain timing with other devices in a live setup.

Is it possible to use the Zoom B1 Four’s USB audio interface function while simultaneously running an external expression pedal through the control input, and if so, are there any limitations on which effects can be controlled this way?

Yes, you can use the Zoom B1 Four’s USB audio interface function while running an external expression pedal through the control input at the same time. However, the expression pedal can only control certain effect parameters that are assignable within the unit. Not all effects are controllable by the expression pedal, so you’ll need to check the effect settings to see which ones allow expression pedal assignment. Otherwise, both features work together without major limitation.

I have a remark regarding the description

Тype: Multieffect

Multieffect is a device that combines multiple effects into a single unit. It allows players to switch between various sound effects - such as distortion, delay, reverb, modulation, or dynamics - and often includes the ability to create and save custom presets. Multieffects are popular for their versatility, compact design, and convenience in both live performance and studio use.

Battery Operation: Yes

Battery power provides flexibility and mobility. This feature allows you to use the device anywhere, even in places where an electrical outlet is not available. Battery power is ideal for situations that require portability and independence from the grid, whether you're outdoors, on the road, or in a location with limited access to electricity.
