LMMS now works on OSX (with bugs and crashes)

Rendered the title theme midi from the old DOS game, called CyberMage:

Back then mp3 was not yet invented, so all game music was in midi format, usually relaying on a standard sample set, called General MIDI sound bank. Different audio hardware came with different implementations that that sample set, so all game soundtracks of the era performed incorrectly on all but some single audio card the composer had while making the song. Typically composers used high end midi keyboards to produce the songs, which programmers just thrown into the game, so in reality no card may have been compatible.

sound banks are one thing, the other is that what those games used was basically 'raw MIDI'. with your synth-pop example: a synth-pop musician would play a MIDI keyboard connected to a synth which would spit out sounds from the soundbank, but it would then be converted to audio through a DAC and fed through a chain of effects which modify the resulting sound-wave. then, all those synthesized instruments would be mastered with equalizers, filters, compressors etc. to achieve just right sound. also, the parameters of a synthesizer itself (e.g. a shape of the underlying wave could shifted from sine to square, or its attack and decay times could be altered) and those effects (e.g. a distortion could be disabled at one point to make a quieter part of the song seem more pleasant) could be modified dynamically, as the song develops - but it's something that's arguably more obvious in instrumental electronic music (happens in synth-pop too, but it's not as noticeable as in e.g. IDM or trance). old vidya music would not have those effects or those dynamic changes, it would be an output of pre-programmed synths.

BTW not all old video game music was based on the MIDI standard. old computer games and demoscene stuff relied more on trackers, which are more like sequencers/samplers
