Arturia MiniFuse 2 is a compact 2-input / 2-output USB-C audio interface built for stereo recording, two-person sessions, singer-songwriter setups and hardware integration. Standard MiniFuse 2 models add 5-pin MIDI I/O and a USB-A hub. The Black with OTG variant is a different dual-host configuration designed to route audio between a computer and a phone, tablet or second computer.

Important Variant Difference: Standard vs OTG
| Black / White | Standard MiniFuse 2 configuration with 2-in / 2-out audio, 5-pin MIDI I/O, USB-A hub and USB-C computer connection. |
| Black with OTG | Dual-USB host design with a main USB-C computer port plus a dedicated USB-C OTG device port for phone, tablet or second-computer workflows. It supports bidirectional two-way OTG audio routing. |
Please choose the variant based on workflow, not only color. The OTG version is a distinct connectivity design and should not be assumed to have the same rear-panel connections as the standard MiniFuse 2.
