I had a debate with Tao in 2000 regarding some of his earlier tunes. As his Magic Synth player became advanced he added more Sid voices to his tunes. So by the demo "Steps" the tunes featured two Sid voices. He decided to update his old tunes using the new player.
I've now decided to include the original older tunes in the next update as the aim of the SNDH archive is to be the definitive ST chip music resource on the internet.
hopefully a release is imminent however currently working away from home so my ST time is limited :(
