AdLib Music by Jozz

The Danish pianist Johannes Bjerregaard not only composed great C64 tunes, he also created a lot of AdLib tunes in 1991-93 in his own players. There were two different player systems – the early JBM player with about 9 tunes, and SEQPLAY that recorded songs through MIDI.

This blog post contains all of these AdLib tunes, of course saved as MP3 for easy listening.

The JBM Player

As far as I can tell, the first player system from 1991 was a classic music player like on the C64 where notes were somehow typed in instead of recorded. Johannes made 9 tunes in 1991 to 1992. My favorite among these is “DDD” which is truly amazing. Make sure you check that one out.

Note that “15L” is a conversion of his own C64 tune “Shape” from 1988.

I recommend you use a DOS emulator to play these files. Go to the folder and type PLAY followed by the file including the extension – for example, PLAY DDD.JBM plays my favorite tune.

The SEQPLAY System

This was a MIDI editor system with recorded notes from a keyboard, then edited in a proprietary character screen editor written in Borland Turbo C. Each song had three files; INS, PAT and SNG.

The music player could play songs on a Roland SCC-1 as well as AdLib, but as far I as I can tell, the INS file had to be populated with instrument data before an AdLib version would play as well. Most of the songs I have from him are supported this way, but not all of them – about 70 to 80% or so. The ones that had an INS file with all zero bytes played nothing but noise on AdLib.

The songs without instrument data are of course not included, but I also discarded one or two songs that sounded like Johannes had merely dumped in an AdLib instrument set then forgot to tweak them. I also had doubts about a few others that were included – maybe an instrument or two needed a twist too.

The theory that Johannes first recorded a song using Roland SCC-1 and then later adapted an instrument set for the AdLib version is also supported by the fact that a few of the songs have a second “Edit” version where the instruments have been tweaked, yet all the notes are virtually the same.

I recommend you use a DOS emulator to play these files. Use the PLAY.BAT file to list and play the files. PLAY without a parameter lists all the files on one screen (very handy) and then PLAY followed by the file but this time without the extension – for example, PLAY YOEL plays the last one. Note that the archive include songs that doesn’t have AdLib instrument data. These will just mostly sound like noise.

  1. Thank you so much for sharing these! I am a big fan of JB’s music on the C64, and I had no idea he dabbled in AdLib, too! These are real gems.
