I'm just starting this topic, because not many people talk about library music on reel to reel tape. I'm just kinda wondering if anyone else knows about this stuff, outside of me. I know about some things, like the fact that tapes with that kind of music were usually pressed at 15 ips (inches per second), and occasionally 7 ips. They also of course contain, of course, to quote my Emil Ascher library music sampler, professional quality transfers of library music tracks. I also know that for some tracks from 78s, they were originally recorded in stereo, but were pressed on of course, mono 10 inch vinyl.
