Added
- The number of seconds to wait before a SoundFont begins loading after using the switch button can now be adjusted (new configuration file option).
- MT-32 ROMs and SoundFonts can now be loaded from USB mass storage devices.
- This feature should be considered unstable/experimental - some USB disk/Raspberry Pi combinations can encounter freezes/crashes.
- SoundFonts will be rescanned and the indices updated if a USB storage device is inserted or removed.
- USB storage devices must be FAT32 formatted.
- MT-32 ROMs must be located under a
romsdirectory on the root of the device. - SoundFonts must be located under a
soundfontsdirectory on the root of the device. - Only one USB storage device is supported at a time.
- The SoundFont index continues counting after the last SD card SoundFont index. If there are no SoundFonts on the SD card, the first USB storage SoundFont starts at index zero.
- Special thanks to @rsta2 for providing important USB driver fixes and mmmonkey Pete for donating a Raspberry Pi 3B for testing!
- Ability to set master volume gain and reverb gain for mt32emu (new configuration file options).
Changed
- Update to circle-stdlib v15.6/Circle Step 43.3.
- Update to inih r53.
- Update to FluidSynth v2.1.8.
- Update ARM toolchains to 10.2-2020.11.
- Config file options are now case-insensitive.
- The
usbconfiguration option has been moved to the[system]section. Please update your configuration file if you use this option.
Fixed
- Large files mistakenly placed in the
romsdirectory could cause mt32-pi to crash on startup (issue #93).
Removed
- Old ROM loading behavior now removed. If you have
MT32_CONTROL.ROM/MT32_PCM.ROMfiles in the root of your SD card, please move them to theromssubdirectory otherwise they will fail to load. - Unused USB drivers removed (kernel size reduced).
- Unused C standard library functions now removed by linker (kernel size reduced).
