A small update on the state of things.
On saturday my GF was out with her girl friends so I had the whole evening to myself and had the time to fix everything (and play some Ni No Kuni on Switch).
Microsampler editor/librarian works like a dream. I wish it had a pattern sequencer for making more precise sequences than the on board sequencer but apparently you can import SMF-files for that.
GT-Pro editor works great too. I can build my complicated guitar effects on a big screen and then just dump then onto the machine and shred away. Nice!
The XV-5080 editor didn’t work at first but it was due to a crappy chinese USB/Midi -cord. As soon as I directed the midi to go through my Microsampler, everything started to work beautifully. As a bonus I can preview the sounds I make with a real keyboard instead of pointing and clicking the keys on screen. The XV-5080 has two midi ins so I can still keep it hooked up to my MPC Live and have the editor plugged in at all times.
As an added bonus I got the editor for my weird Neurotronics Laxman to work too. I found this at a fleamarket for 6€ recently and it’s a kind of a relaxation machine/mp3 player that has audio output but also includes a pair of goggles that show vibrating and flashing colours. Now I’ll be able to program my own light shows with the XP and the editor.
