All user reviews for the M-Audio Biport 2x4s

Excellent qualitprix
2 in 4 out noon and allow great flexibility for complex configurations twelve o'clock
I personally use all my prfre plutt available ports to cascade to the three MIDI instruments on a single port
over this device allows me to generate a signal for LTC stripper tape and read the timecode, transform midi timecode to synchronize a computer sequencer has a analog tape machine
considering the price, the two-port is the only machine so allow me great flexibility

UTILIZATION

Never had any problem with drivers
the integration software is good and trs trs stable, I use all soft currents with this unit without any concern

OVERALL OPINION

Definitely the best choice for those who need more than one MIDI input / output and an external analog synchro machine
excellent qualitprix
