The problem is simple and frustrating.
I'm using MMM 2017 and I've noticed that when using DN-e1 and Revolta 2, and testing other instruments from the synthesizer, it would automatically change to some default.
For example, if I want to use 'Amazon,' it would change to 'Erosion' every time I replay the music. I've seen some similar complaints: https://steamcommunity.com/app/265420/discussions/0/45350791044383006/
and I hope some of you in this community could help me figure out whats the problem.
Please keep in mind that I'm new to MMM!!
Thanks
