• Optimizing the MIDI banks management system for MultiBanks (Thanks to Jean Pierre Cimalando for a work!)
• Fixed incorrect initial MIDI tempo when MIDI file doesn't includes the tempo event
• Fixed an incorrect processing of auto-flags
• MAME YM2612 now results a more accurate sound as internal using of native sample rate makes more correct sound generation
• Channel and Note Aftertouch features are now supported correctly! Aftertouch is the tremolo / vibrato, NOT A VOLUME!
• Added optional HQ resampler for Nuked OPL3 emulators which does usage of Zita-Resampler library (Thanks to Jean Pierre Cimalando for a work!)

• Added support for real-time switching the emulator
• Added support for MAME YM2612 Emulator
• Added support for CC-120 - "All sound off" on the MIDI channel
