Just done an experiment because of the zero cv/gate on maschine+.
So I directly connected my series of Behringer "tribute" synths to the M+ via USB in standalone mode.
Everything worked straight off (remembering to allocate in M+ MIDI settings and pad assignment - the synths show up under their recognisable names). The patch bays on the Behringers worked fine as a bounce on to a eurorack and also worked on MIDI transmission chain! Nice!
Tested on TD-3, Craver, Model D, Neutron and Pro-1.
Anyone got other results with other hardware synths / manufacturers?
