"An ambient improvisation, played on my RMI KCII. Reverb added. Images are of the sea in Japan and some of my tiny oil-on-glass-slide paintings. Sept. 28, 2016 in my home studio."

Spotted the above via the following listing. You can find additional demos, info, scans, pics and a demo record featured in additional posts here.

"TRUE MUSEUM PIECE, extremely rare.

Sound very similar to the RMI harmonic synthesizer (used by J.M.Jarre in Oxygene)

Everything is working, the synth has never been modified or repaired, all the internal components are "as it came from the factory".

With paper memory reader for sounds totally revised!

there are several "memory sheets" for the digital system of memories it used (visible in the photo).

Synthesizer von Gestern (Synths of the Past) Vol 2, Matthias Becker.

via this auction

"Beautifully-produced second volume of Matthias Becker's authoritative 'Synthesizers of the Past' book - in German, but with so many superb illustrations that it's hardly necessary to read the text. New, unused, still sealed. The photos were taken of another copy of the book.

Too many highlights to mention all, but the book covers such absolute classic synths as the Trautonium, ARP 2500, EMS Synthi 100, E-mu Modular, Steiner-Parker Synthacon, RMI Harmonic Synthesizer, Birotron, PPG 1002, Moog Taurus and Liberation, Roland System 700, Synlab Modular, Roland SH-7, Crumar DS-2, Korg Sigma, ARP Quadra, Roland RS-505 and VP-330, Fairlight CMI, Realton Variophon, Oberhaim OB-Xa, Xpander and OB-SX, Gleeman Pentaphonic, RSF Kobol, Emulator 1, Synergy, Roland SH-101, TB-303, TR-606, MC-202, Jupiter 6, Syntec Banana, SCI Prophet T8, OSCar......... an incredible roster which would (in the beautiful condition they are in the photos) probably now be worth over half a million US dollars.

All with superb photos by Dieter Stork. Hardback, beautifully printed on very high quality paper, bound to the highest standards. A coffee-table book which is also a superb source of information. The Rolls-Royce (OK, Mercedes) of synth literature. (I should know - I produced the Ford Fiestas of the genre.) ISBN 3927954012, printed in 1995."

RMI Harmonic Synthesizer and Keyboard Computer demonstration record, part 2

Uploaded by baward on Jul 24, 2011

"RMI has just released TWO GREAT CONCEPTS on the musical public -- HARMONIC SYNTHESIZER and KEYBOARD COMPUTER. You will soon be hearing our sounds from other sources, since recording studios and touring groups are starting to use the new instruments. It appears we have hit on something -- see what you think.

Everything you hear on this record was recorded LIVE in REAL TIME by ONE PERSON. Any cross--fading or instruments appearing in contrast between the left and right channels was accomplished by the performer's use of the pedal -- not the recording engineer. RMI's concept allows the single performer to create five Independent channels of audio, bringing studio effects to the concert stage. Live concert ensemble will be improved while studio recording time will be greatly reduced.

Mike Mandel, keyboard wizard, was the first "outsider" to try our new instruments. Mike took to them like a fish to water. Cut one on side two is a section of an improvisation that began after only two hours. Although a tape was made at the time, there had been no plans for a record. Mike's inspiration from this first meeting convinced us that this cut was a must.

Clark Ferguson, marketing director at RMI, has composed music to illustrate the potentials of the new instruments in dealership concerts and demonstrations throughout the country.

Carlo Curley, a young and exciting concert organist, feels with the advent of the RMl Harmonlc Synthesizer and Keyboard Computer, a new era of expression has arrived. During the recording of the Daquin "Noel," Curley was inspired to improvise on the theme using the Keyboard Computer strings.

[RECORD SIDE TWO]

MANDEL DOES IT -- Full use is made of Channel Three and the Pitch Bender. A rapid percussive arpeggio is programmed on the sequencer as a background. Filter "sweeps" are used as accents.

NON-PIPE ORGAN -- You know what we mean. Characteristic keying noise and percussion are created by card #F3186. #1184 produces a typical setting. Rotating speaker effects are created by Chorus and the Vibrato Touch Bar.

JAZZ FLUTE -- Card used - Jazz Flute #F2335. Twelfth harmonic is percussed rapidly to create "over--blowing" transients. Fundamental and other harmonics on card #F2335 are delayed by Slow Attack mode.

RECORDER AND HARPSICHORD -- Alto Recorder #F2065 is heard with slight vibrato on channel one. Pulse cards #SPG1001 and #SPG2002 are percussed through channel two (no vibrato). Quick changes are made with the pedals.

MOMENT MUSICALE (Schubert) -- Percusslve accompaniment on Computer. Solo line is played alternately on the Synthesizer Left and Right Voices.

NOEL (Daquin) -- Flutes and harpsichord are the main instruments. Light bells are "sequenced" at random on the Synthesizer.

Synthesizer von Gestern (Synths of the Past) Volume 2

via this auction

"This is a brand new sealed, unopened copy of the rare classic synthesiser book, 'Synthesizer von Gestern' by Matthias Becker. It is the second volume, which (at 146 pages) is larger than the first, and includes an incredible array of classic synths. Unlike the A-Z or Museum book, this is a beautifully-bound hardback, and is printed on very good quality paper. It is the first and only edition of this rare book. The picture is of another book, but it is identical.

When this book was out of print and no longer available, copies were changing hands for 100GBP-plus. Then the publishers found one last pallet of books in their warehouse, gave them to the author in lieu of royalties, and I drove to Koeln in Germany to bring back all I could.

It is in German, but so much of the book is taken up with beautiful full-colour photos and excellent illustrations that that isn't as important as you might think, if you don't speak German. It's a great coffee-table book, but full of serious information too - and the photos are in a class of their own. Crisp, beautiful, detailed, professional!

The book starts with an in-depth interview with Oskar Sala, inventor of the Mixtur-Trautonium (used for the entire soundtrack of Hitchcock's 'The Birds'). Fantastic photos of his studio and various Trautoniums.
Other synths and electronic instruments covered in detail include:-
