Sorry, my mistake. I vaguely remembered discussing with a mate that the Music Rooms had been released sometime in the 80s. I did little a research and turns out there was only one track on a compiliation put out by Elektra with just one track. You may be right too that Rabe isn't a close comparison, put Neural Syntheses to me seems far more fractured in terms of sound than Amacher. Rabe in spirit if not in practical application approaches more towards Amacher's psychoacoustical studies of harmonics and implied sounds.
Cheers
