Overview
MOTU builds the M4 as a desktop USB-C audio interface for recording, mixing and podcasting, with MIDI connections on board. It links to a computer or phone over USB and offers low latency monitoring while tracking.
Extra outputs and MIDI ports let one box route several signals and drive a MIDI keyboard over a single USB-C link. With no listed details on preamps or phantom power, buyers must lean on MOTU's own spec sheet when planning inputs.
Who it's for
Producers running monitors alongside other outputs, or podcasters recording from a laptop, get the extra routing and bundled software. Someone with a single microphone can manage with a smaller interface.
Pros and cons
- Four inputs and four outputs
- MIDI input and output built in
- Low latency monitoring
- Recording up to 192 kHz
- Preamp count, phantom power and bit depth not listed
- Channel count conflicts with 4x4 naming
- Operating system support unclear from listing
Performance notes
Recording quality depends on the analog input stages and the converters, and the listing names only the top sample rate. Low latency monitoring lets a performer hear the input without waiting on the computer's buffer. USB-C carries both audio and MIDI, so cable quality and the host driver affect stability.
