## 1.5.0 2020-09-28 * Drum note length expanding is now supported in real-time mode (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!) * Added support for OPNA chip with Neko Project II Kai YM2602 emulator usage (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!) * Added VGM file dumper which allows to output OPN2 commands into VGM file. (A new MIDI to VGM tool is now created with basing on libOPNMIDI) * Fixed an incorrect work of CC-121 (See https://github.com/Wohlstand/libADLMIDI/issues/227 for details) * Internality has been refactored and improved
