Hey!
Just bought a few sample packs and feeding it to my Digitakt. I have read somewhere that it’s crucial to disable MIDI when using USB for transfers to make it go faster. Did that… but the transfer speed is still at 0,33 MB/s. Wasn’t that a flash drive? Why is it so slow? Am I doing it wrong?
The DIN midi transfer rate is 3125 bytes per second (that’s for the payload).
So 0,33MB/s is already mindblowing fast in comparison. That’s a factor 100 
You cannot compare it to a normal USB data connection. It still has to adhere to the MIDI protocol and has to be send through the MIDI processing on the receiving end.
Well yeah… and on the other hand there is Overbridge which uses the same port and now you tell me how much data per second is necessary to stream 8 tracks and whatnot to your DAW - so I wouldn’t say this is absolutely impossible to change that in the future… Maybe just a quick / lazy implementation with sysex … hopefully?
I guess max transfer speed would also depend on the max write speed of the +drive. Are there specs on that anywhere?
I wouldn’t count on future speed improvements, because (as I mentioned above) it’s not a normal file transfer (or comparable to audio streaming over USB).
All the data gets funnelled through the MIDI-in processing on the receiving end, which needs to examine each bit to extract the real payload from the MIDI stream (which is much more effort than streaming a 1-to-1 copy directly to the +drive like a normal file transfer would do).
I guess the MIDI-in processing part is simply (hardware-wise) not designed to give you much more speed than there is already.
The only improvement I can think of would be if they implement a real file transfer via USB (like on the Octatrack), but I’m not sure if that’s possible without any hardware modifications.
