Miditech 4merge USB

Miditech 4merge USB gets easily confused by my MIDI controller keyboard when I switch configurations (maybe it sends SysEx that ain't handled well or maybe it gets overrun by a flood of too many MIDI messages at once, I wouldn't know). Workaround: I keep the box near to me to reboot it (unplug-replug), thanks to the long MIDI cables I happen to own.

Otherwise, for the time I used it, it worked well handling usual MIDI messages (including but not limited to note off, note on (w/ velocity), poly touch (good!), expression).

did buy this to use with dave smith prophet 6 module and mopho, but it did not work ... smiths problems
usefull with other gear though

excellent price
works faultlessly
quick delivery
no fuss
what more do you want ?

function with lag bad quality

I have active sense midi message sent from 2 roland boutique synth plus arturia keystep notes and it crashes all the time after a few minutes playing. Not reliable at all especially for a live .... at least with these instruments .
