MG completely stopped workin after many updates form the Tascaml interface in Windoes 10

Midi Guitar and Midi Bass can't see Tascam 2x2 interface anymore

in MG interface section, open the ASIO setup with the DRIVER button, and select the proper in and output channels and samplerate. Some drivers only allow the samplerate and buffersize to be set there. So set it to buffer=256 and samplerate=44100 there too.
