Low latency and low jitter in extensive MIDI data transmission

• When sending MIDI data to multiple sound modules, the UM-880/550 maintains accurate synchronization with low latency and low jitter data transfer. (fig2,fig.3)

The most suitable for Real-time performance

• The high speed transfer capability of FPT allows for high resolution data transfer without comprimising the performer’s subtle expressions even in live performance.

Works with any music application software
