Switched on POKEY - S.O.P. Track 7 - Prelude and Fugue No7 in E-Flat Major

RSS Bot · March 22, 2019

This track may seem a little plucky but if you listen to the tracks in order your ears may become conditioned to the point where it doesn't sound half bad. Or maybe not.

All the rest of the music has been entered into the MIDI Music System and is ready to record once some new sounds can be programed. For this track minor changes to the BASIC software was made to give a quick pluck or hit sound. I was a little supprised that a delay loop was needed when the program was compiled.

This is the code that produces the sound. It occures so quickly that there didn't seem to be much need to check for a new note during the play period. The effects processor on the mixer was used to add some depth to the sound.
