I have MIDI files you can customize in a workstation to fit your needs. You can take these files and add beats, edit the notes, assign the instruments, etc. Here are some examples of what you can do. All I did with these is assign instruments and add beats (no other editing): Cobblestone https://soundcloud.com/tonal_spaces/cobblestone Latinique https://soundcloud.com/tonal_spaces/latinique Plucky https://soundcloud.com/tonal_spaces/plucky Joy https://soundcloud.com/tonal_spaces/joy I can give you a MIDI file of any length, meaning it can be 30 minutes or an hour long with no repeats. I also have other examples at https://soundcloud.com/tonal_spaces Message me with any questions.
