I´m not a MIDI Interface-Prof but AHT Europe developed a brand new one for the Amiga.
Mhh.. I searched their site but no infos about it :-(
But I have two Midi-Interfaces at home and don´t need them anymore.
Maybe you´re interested? I could send you some pics...
For sequencing I use OctaMed Soundstudio but Camouflage is more professional for using MIDI. It´s not THAT easy to learn.
But if you´re in the topic these progs should be fine.
Here are some links:
Sorry, I can´t find the Freeware page from Camouflage...
and I´m in a hurry.
But I´ll be back soon, okay?
See you later.
