Today I have added a number of features to the Sega Master System MIDI Interface (SMSM).
For the YM2413 FM chip, the interface now has:
• More accurate pitch calculation
• Support for tunings other than 12-TET, from 4-TET to about 18-TET
• Support for different tunings of concert A, from 377Hz to 504Hz (in intervals of 2 - 4 Hz).
• Support for user-defined pitch bend ranges, from +/- 1 semitones to +/- 12 semitones
• Support for user-defined transposition
