Midi, dn, dt, st, external hardware

Hello, im kind of new in this, im using DN, DT and ST, but i wanna use my Minilab 3 with the sound that i have in analog lab, also the Uno synth pro, and many more to use the midi channels, i did but only the 8 tracks can handle in DT, in the DT i couldnt and syntakt dont know how, the thing is that i wanna recorder the sounds of my external gears in the sequencer of this 3 fellas, but im kind of frustrated cuz i dont know how, in the DT the live rec works but no sound, i have the arturia minifuse 4 with 2 channels and i plug the audio in the digitone cuz no space available in the other 2 boxes cuz i have them sync. So how can i do it not only for hear the sound but also rec the sound into the boxes.

Thank you so much
