MT32-PI.EXE/MT32-PI.TTP/mt32-pi-ctl is a control program for the mt32-pi MIDI synthesizer available for DOS PCs, Atari ST and Amiga computers as well as modern systems running Linux and Windows.
- Supports sending mt32-pi's custom System Exclusive messages for temporary configuration of SoundFonts & Co.
- Can send standard MT-32, GM, and GS reset sequences
- Can send screen text in MT-32 mode and 16x16 1bpp bitmaps in SoundFont mode to the mt32-pi's display
- If that's not gimmicky enough for you, it can also send 8 characters of text as a 16x16 bitmap using the Miniwi 4x8 font
- Custom MIDI messages from the command line
- Can send SYX-files of any length containing any number of SysEx messages
- DOS version compiled for 8086 Real Mode, so should work on pretty much any system with an MPU401-compatible interface
- Amiga version is compiled for AmigaOS ≥1.3 and supports both
camd.libraryand direct serial port access, so it likewise should work on pretty much any system - Useful for making game/application-specific start-up scripts to correctly set up the synth
MT32-PI.EXE/MT32-PI.TTP/mt32-pi-ctl accept the following UNIX-style parameters:
USAGE: MT32-PI.EXE [OPTIONS]
OPTIONS:
-p [ADDR]: Set the port address of the MPU401 interface. Default: 330.
USAGE: mt32-pi-ctl [OPTIONS]
OPTIONS:
-S: Use direct serial port access instead of camd.library.
-l: The camd output location to connect to. (Default: out.0)
USAGE: MT32-PI.TTP [OPTIONS]
OPTIONS:
[No special options as the Atari ST has a built-in MIDI port which is automatically used]
This is a CLI/TTP-utility. If you launch it directly from TOS a graphical prompt will let you input the parameters. Though for more convenience I would recommend a text based shell like EmuCON or Okami.
Note that quoting in Atari ST shells seems to work a bit different than in other systems (or maybe I don't get it but the following works, in any case). Quoted parameters must use single-quotes, be located in front, and the parameter needs to be within the quotes.
Example: When on other systems you'd write mt32-pi-ctl -m -t "Hello, World!", on Atari ST
it should be MT32-PI.TTP '-t Hello, World!' -m.
USAGE: mt32-pi-ctl [OPTIONS]
OPTIONS:
-p "[CLIENT]:[PORT]" : The ALSA MIDI client and port address to output to (*MANDATORY*).
To find out which client/port to use, you can run aconnect -l to list available devices.
USAGE: mt32-pi-ctl.exe [OPTIONS]
OPTIONS:
-p PORT : Set MIDI output port number (*MANDATORY*).
-l : List available MIDI output ports and exit.
-h/--help: Print this info.
-v/--verbose: Be verbose about what is going on.
-r/--reboot: Reboot the Pi. Will block for a few secs to give it time.
-m/--mt32: Switch mt32-pi to MT-32 mode.
-g/--fluidsynth: Switch mt32-pi to FluidSynth mode.
-b/--romset [old, new, cm32l]: Switch MT-32 romset.
-s/--soundfont [NUMBER]: Set FluidSynth SoundFont.
--mt32-reset: Send an MT-32 reset SysEx message.
--gm-reset: Send a GM reset SysEx message.
--gs-reset: Send a GS reset SysEx message.
-t/--mt32-txt "Some text": Send an MT-32 text display SysEx.
-T/--sc55-txt "Some text": Send an SC-55 text display SysEx.
-P/--sc55-bmp FILE.BMP: Display a 16x16 1bpp BMP on the screen. (SC-55 SysEx)
-X/--sc55-btxt "SomeText": Display a string on the screen as a Bitmap using the
miniwi 4x8 font. Max. 8 characters (SC-55)
-N/--negative: Reverse image color. Use with '-P/--sc55-bmp'.
-M/--midi "C0 01 C0 DE": Send a list of custom MIDI bytes.
You may specify multiple options, i.e. MT32-PI.EXE -m -t "Hello, World!" will first send the MT-32 mode command and then the screen text.
The MAKEFILE is written for the DOS-version of Open Watcom C 1.9 as it can generate Real Mode executables. The Sourceforge release works perfectly in DosBox.
Make sure you have the environment variables correctly set up. For that, DosBox users will need to run the AUTOEXEC.BAT code supplied by the installer.
Then run wmake in dos_src/ and compilation should run. Optionally, if you also have upx installed in your DOS environment, you can run UPXCOMP.BAT afterwards to pack the EXE and save a couple KB of executable size. wmake dist will also compress and then copy the resulting file to dos_bin/.
The Makefile is written for bebbo's amiga-gcc. After you have installed the toolchain, you also need to run make sdk=camd in your amiga-gcc source directory to install the camd library.
After that, you can run make and make dist in the amiga-src/ folder. If you have installed amiga-gcc somewhere else than /opt/amiga, you will need to adjust the PREFIX variable in the Makefile accordingly.
The Makefile is written for Vincent Rivière's m68k-atari-mint cross-tools on Linux or (probably) WSL. For Debian/Ubuntu I recommend using the repositories on the site. After installation of the toolchain, run make and make dist in the atari_src folder.
You need to have gcc, make, and the ALSA/libasound development headers installed. On Debian/Ubuntu sudo apt install build-essential libasound2-dev does the job. Afterwards, run make in the linux_src folder.
The Makefile is meant to be used on a Linux host with the i686-w64-mingw32 toolchain. On Debian/Ubuntu sudo apt install mingw-w64* does the job. Afterwards, run make and make dist in the win32_src folder. If you want to compile on Windows, MSYS should work but you might need to adjust the executable names in the Makefile.
The BMP file is in the archive. I made it with GIMP but MS Paint and others should work just fine as long as the file is 16x16px monochrome (1-bit indexed).
