For the vArranger I'm thinking of getting the roland integra 7 sound module OR the roland FA-06 keyboard which claims to be able to work as a sound module as well, it also has a built in user friendly multi track sequencer that (in theory) I can import the vArranger midi file into it then loop add more tracks using the FA-06 internal sounds.
I currently am using cubase 9.5 (with a roland Bk7m as the sound module) but am shy of cubase's sequencer (no experience with it) when it comes to looping, however the possible game changer to force me to learn is the integra 7's 6000 sounds capacity, but I'm not sure of the compatibility of the roland integra 7 and the i.e. roland BK7m arranger files.
I like Roland :)
