Hey there Sushikoba,
I wrote the midi for this soundtrack using a midi keyboard and a program called Korg Gadget, which I had on my iPhone. Unfortunately - I just switched to an Android phone, which makes these files inaccessible to me at this time. I apologize for this. However, I still make music and am contemplating re-opening my commissions page for soundtrack work.
If I can be of any assistance going forward, please let me know. Thanks!
