Best metering and MIDI alternative

MOTU M2

Indicative price: About £180–£220

Product-specific evidence · sources checked 17 September 2026

A two-in/two-out USB-C interface with colour level meters, MIDI I/O and independently controlled monitor and headphone outputs.

Best for: Musicians and creators wanting two inputs, clear front-panel meters and MIDI

Potential drawback: Costs more than basic two-input interfaces and offers no onboard streaming mixer

Research assessment

MOTU's M2 is a strong two-input alternative for buyers who value clear front-panel metering, MIDI I/O and low-latency monitoring more than streaming-oriented software mixing. Both microphone inputs can also accept line or instrument signals, and the monitor and headphone outputs have separate controls. It costs more than the cheapest two-input interfaces, and its loopback/software workflow is less immediately creator-focused than Wave XLR; confirm driver support for the intended operating system before purchase.

Reasons to consider
  • Clear colour meters, two flexible inputs and useful MIDI connectivity
  • Strong measured conversion and latency performance for a compact interface
Limitations and checks
  • Costs more than basic beginner interfaces
  • Less purpose-built for software audio routing than creator-focused single-input interfaces

Best compact studio expansion

Focusrite Scarlett 4i4 4th Gen

Indicative price: About £220–£260

Manufacturer specification evidence · sources checked 9 October 2026

A four-in/four-out desktop interface that expands beyond the 2i2 with additional line inputs, four line outputs and MIDI while retaining Auto Gain and Clip Safe.

Best for: Multi-instrumentalists, synth users and two-person recording with MIDI

Potential drawback: Extra routing is unnecessary for a simple single-microphone setup

Research assessment

Scarlett 4i4 is the logical step above the Solo and 2i2 for buyers who need extra line sources, more output routing or MIDI without moving to a rack interface. It keeps two microphone preamps, so four-in/four-out does not mean four simultaneous microphones. Confirm the computer connection, monitoring plan and whether the included software adds value before paying for the extra routing.

Reasons to consider
  • Two mic/line/instrument preamps plus two additional line inputs
  • Four line outputs, MIDI I/O, Auto Gain and Clip Safe
Limitations and checks
  • Only two microphone preamps; inputs three and four are line-level
  • The headphone and monitor routing is more complex than a basic single-mic interface
  • Check operating-system and Focusrite Control 2 support for the intended computer
