Changelog * Added an ability to disable the automatical arpeggio * Added an ability to set the count of loops (how many times to play the song) * Added an ability to disable/enable playing of selected MIDI channels * Fixed memory damages and crashes while playing XMI files * Added bank-specific MT32 defaults (to don't confuse XMI playback between different games, works for AIL and IBK only, and for WOPL if set at the header) * Added the chip channels allocation mode option * Fixed the playback of multi-song XMI files * Added an ability to switch the XMI song on the fly ALSO (future updates) * Fixed the work on big endian processors * Fixed ARM64 build on some platforms * Improved support of the EA-MUS files (Thanks to [dashodanger](https://github.com/dashodanger)) * Fixed crash on attempt to change the volume of a blank note
