I downloaded the MIDI files from your dropbox (Cactus)without issue. Midi files are very very small. I sent four to magik570 via email without issue.
 
If I understand the reason for needing these MIDI files, it is to create or use for the purpose of playing live. I assume in a club or bar for example. I want to start another thread about this issue.
 
If you guys what all the midi files I have just say so and I will try to dropbox the whole thing.
