Just a plain C++ project exploring AdLib Sound Programming. Still in a very early state. Not sure where it leads to. I want to build a basic composing tool some day.
I followed tutorials by root42 to get me started.
Also started to explore how to mess with int 10 and text mode, and tried to mess with the OPL2 chip of the old Sound Blaster and Adlib cards.
- Contains some code from the https://github.com/learosema/asciijoy repository for basic text mode functions.
- OPL2 lib used from https://github.com/Superilu/lib16, but changed the instrument_t struct to also contain a
drumType

The only 32 bit platform tested so far is 32Bit DOS with DOS4GW and Watcom C.
Type wmake. It will create an MUZIMAKE.EXE and copy
DOS4GW.EXE into the current dir. In the current state, this one is only a bare bone skeleton.
There are a couple "tests" in this project. Well, they're not unit tests, just tinier programs I built for experimentation and testing. They do give some confidence to ensure the things work :D.
wmake testsThis builds a couple of test programs:
testinstfor testing the instrument data structuretest_bnkfor testing bnk files, playing every instrument inside a bnktest_rolfor testing the rol file loading routinetest_tmrfor testing timer interruptstest_kbdfor testing the keyboard interrupttest_evtfor testing an event system, inspired by the Windows APItest_uifor testing the textmode UI. It has knobs, inputs, lists and more
Type wmake /f makefile.16
Not yet. I need to understand how video ram access works and put together the makefile. I guess this is a good place to start: https://www.delorie.com/djgpp/doc/ug/compiling/port16.html
Because I can. Yeah, there is perfect music software out there. Adlib Visual Composer by Ad Lib Inc or Adlib tracker, for example. They're awesome <3.
I still wanted to code something like that myself, for educational purposes.
Like the hard mode in Monkey Island.
- thank you root42 for making dosadlib and making a youtube video about it! Helped me a lot to get started.
- Angela Galliat helped me a lot with the programming and optimization of the software architecture
- OPL2 code taken from lib16 by SuperIlu which is in turn based on ArduinoOPL2, ported from a class interface to plain C
