Hey y’all ! I’m new to this forum and I don’t know if it’s the right place to post these kind of stuffs but anyway here is my question…
Is there a way to run more than one module at the same time so I can directly mix the next module without having to cut the sound because of the loadings ?
Nopes, sorry.
Damn…I will stick to Milkytracker’s tabs then. Thanks man !!! 
You could run several instances of Renoise.
For Mods, you are always better off in Milkytracker.
