Programming the OPL2 FM chip on the original AdLib card can be a bit tedious. Join me in this episode to learn how to program the drums on the AdLib card to create a simple sequencer or drum machine. In the future we will also look at the melodic instruments, but for now we try to create some nice percussion!

Super!

I've literally just finished diving into old PDF files and your videos and I have a working SB playback example that supports different sample rates, 8- and 16-bit and mono/stereo, in a DOS4G/W environment. Couldn't have done this without your SB16 videos to kickstart me :D Thank you very much for your work!

Glad I could help!

Documentation was really scarce back in the day, I'm finally getting my revenge ;)

Really cool. Having written a GUS and an SB music player in the late 90s, Adlib programming was always something I wanted to have a stab at, but never had the mental capacity or free time to dig into. Thanks for providing a glimpse into this world. I might have a go at it for fun some day. (I just wish you'd done it in Turbo Pascal, but hey, I can follow the C code along just fine.)

Porting to Pascal should be straightforward. Even porting to assembly shouldn't be difficult. After which you could just inline it into Pascal. :)
