@NoyzBotChip I'm really not good on "really clean and finish hardware done by myself", I improve on this everyday, but today I'm average. When I do a cable myself It could break and I hate this. Because I don't use the right material...
Music must be fun for me and when I play with hardware I want them to be rock solid. And don't want to stop playing because it is not solid.
So if you are like me, not a really good hardware guy, buy some solid and finish stuff and play music.
It's really fun to have a solid setup. Hardware which tend to break is the worst thing...
It kill productivity and idea and you loose the motivation.
Last, if you want to use midi with nanoloop, this box is the best one : http://m.ebay.fr/sch/i.html?isRefine=tr … mwBanner=1
I have multiple arduino and lsdjmc2 box, and this one is just perfect.
