Iceman! Yeaaaaah! Can't wait. I know you're recording them, but did Sierra ever send you any Iceman files?
I've actually got a few (or at least, one) SC-55 GS files from this game. Definitely the first Chi Chi Bar theme, with the steel drums and whistle. Converted nicely

Anyways, on-topic..
Likewise, for me, Castle of Dr. Brain would be around the bottom of my soundtrack recording list. Might do a 'Dr. Brain' CD with music from all 4 games some day in the distant future though..
I've got the 'Castle' soundtrack sent to me by Mark Seibert (one of the games I was lucky enough to receive the MIDI files from Seibert) and there's really very little music.. as a child, the first 10 times I played the game I never heard any music anyway, as the computers at my school probably didn't have speakers on.. might've heard some PC speaker effects. Certainly no Roland MT-32 goodness.
Anyways. There's the main theme, the computer room theme, the office theme (which I absolutely love, have a million good memories of, and will be recording for a special CD soon)..
/me checks his 'Castle' MIDI's.. wow, haven't loaded THIS patch bank in a looong time.
Ah yes, another Sierra musician parody of the 2001 song (which I'll have just before the warp sound effect and the Office music in my OGG), the Astronomy Room, the Sierra Fanfare, various Castle Halls (barely counts as music, very short loops with fairly boring instruments), Jigsaw puzzle, Robot room, Hangman game, various computer room themes, and some old unused tracks.
Unused tracks:
- Dr. Brain Rap
- Rock, an old version of the Robot theme I think
- Various old versions of the Dr. Brain theme
- An old version of Rock ;P
Some good stuff here! Definitely not enough to bother with a full soundtrack, but some nice themes regardless. Might send Tom a MIDI or three.
Thanks for the memories, ProK.

EDIT: Dug up the old Dr. Brain 'Monolith/Office' OGG file I made back last year sometime. Great memories..
