v0.8.0
216130c

Added

  • Support for the SSD1309 using the ssd1306_i2c driver - many thanks to @flynnsbit for testing!
  • Support for the Blokas Pisound - many thanks to @sigkill for providing the device for development!
  • Support for configuration using MiSTer FPGA's OSD via an I²C control interface in certain cores - many thanks to @sorgelig for collaborating and implementing the MiSTer side!
  • Support for physical buttons and rotary encoders with two "simple" control schemes (new configuration file option).
    • simple_buttons allows connecting 4 buttons for switching synth, switching MT-32 ROM/SoundFont, decreasing and increasing volume.
    • simple_encoder allows connecting 2 buttons and a rotary encoder (with button). Volume is adjusted by turning the encoder, encoder button will be enabled in a future release.
    • Menu system/additional button features will come in future releases; this is just to get basic functionality implemented.
    • Details on how to wire these controls will be made available in the wiki.
  • Animated loading "spinner" for when large SoundFonts are being loaded.
    • This will probably be replaced with a progress bar in the future.
  • Support for Roland SC-55 "graphics" messages when using a graphical display.
    • A good example of this is the Roland "Star Games" demo MIDI (STARGAME.MID).
  • Ability to set master volume gain for FluidSynth (new configuration file option).

Changed

  • SD card I/O speed increased by up to ~180% for cards that support High Speed mode (almost all cards available for purchase today).
    • This should dramatically reduce SoundFont loading times.
  • MT-32 ROM/SoundFont switch messages are now only shown when the appropriate synth is active.
  • A message is now displayed on the LCD for a second just before entering power saving mode.

Fixed

  • Switching MT-32 ROM sets whilst MIDI was playing could cause a crash.
  • Switching SoundFonts too often (especially large ones, and especially while MIDI is playing) could result in a crash due to an out-of-memory condition.
    • This has been solved with some upstream fixes by the FluidSynth team combined with a custom memory allocator that should prevent fragmentation. Many thanks to @derselbst and @jjceresa for their help!
  • Power saving mode would never be entered whilst in SoundFont mode if the user had switched SoundFonts.
