This record is the first L.P. ever to be recorded using only the Electronic Music Studios "Synthi" VCS-3. This instrument has the capability of producing virtually any sound, but was used purely as a straight musical instrument on this L.P. Its range is from the sub-audible to ultra-sonic. No one musical instrument can be played over the range of the VCS-3 synthesizer. RPM’s model being completely standard, with the Cricklewood 3-octave keyboard. The only modification was done at RPM Studios - a potentionmeter control was added, which gave a sliding octave up or down, by rotating the control, thus extending the keyboard to 5 octaves.
"The Classical Synthesizer" was recorded on a 4-Track Studer J-37 tape recorder. To add on more than four tracks, the first four tracks were mixed down to 2-track stereo and then overdubbed, and the process repeated until the work was completed. It says a lot for the J-37 Studer that one title on the LP actually contains eleven individually recorded tracks.
I recommend that you play this disc on a very good hi-fi system and if you own a Quadrophonic synthesizer, listen to it through that system - the sound will amaze you. Be careful not to damage your speakers playing the Bach "Toccata"!!
