Thanks to the suggestion of my friend Neil Haverstick I started to write student level microtonal piano pieces meant to be played on a regular midi controller using a microtonal sound source. There are several free microtonal VSTi’s available and many more paid ones. In the near future I will list some here to help you. The compositions are targeted students with modest a skill level and are free for academic or non-commercial use.
