Tape recorders as musical instruments
Orpheus Institure & Logos Foundation
The analog taperecorder
A detailled description of the analog tape recorder would cover more than a single volume book. Moreover, such books are available in archives worldwide.
Uses in live electronic music
Revox G36: Vacuum tube type
Revox A77: Transistorised version
Revox PR99: Latest professional model produced.
Nagra: portable equipment, top quality but rarely used in live electronics because of the limited motor force.
Otari: Large studio equipment. There are 1/4" as well as 1/2" and 1" types, 2 up to 16 tracks.
Carad: A Flemisch brand, using vaccuum tubes. The most common model was full-track mono.
Phillips: Phillips produced professional audio equipment and taperecorders for studios up to the late sixtees.
Essential features: 3 motors, 3 heads. Speed: 19cm/s, 38cm/s, 76cm/s
Trackformat: Full Track (mono), Two-track (stereo)
Quartertrack models were reserved for the amateur market and found little application in studios or live electronics.
