Ive just listened to the demo-record. Most funky clavnet & piano type sounds. Very nice percusive sounds. Cant realy understand that it was made so early.

Thanks Micke.

It has been known for a long time that is was the RMI :wink:

"Afaik, Jarre didn't use the RMI Keyboard Computer KC-1 on "Oxygene", he first used it on 1978's Equinoxe along with the Harmonic synthesizer"

Sorry, got confused with which RMI was doing what and who.

Well there goes my theory of JMJ time-travelling to 1998 and stealing a Casio CTK for his own diabolical purposes...

Not necessarily, I'm pretty certain he could just play a certain note sequence on the laserharp to open timegates.

I love the laserharp.

Ah! So the coat, glasses and gloves may just be devices to prevent him from randomly jetting off to assorted times and places in the cosmos.
See, it wasn't a gimmick!

I've tried to make RMI emulation once when I covered his Oxygene 4

No, that's not accurate. The booming bass is the ARP 2600, layered with the RMI which produces the metallic, grainy-sounding stuff that adds a little more scope to the ARP bass.

All the tinkly stuff, those fast arpeggiated chords, and of course the O5 bass sequence (rather spiky-sounding) with the "clapping hands" type of sound-- that's RMI Harmonic Synthesizer. It *can* produce some bass sounds but due to the rather weedy filter the bass is never punchy or rubbery or squelchy.

Zanov made better use of the RMI, listen to his "Moebius" and "In Course of TIme" albums -- the RMI sounds rather abrasive and stands out like a sore thumb.

Apologies for resurrecting that old thread btw.

Why would a harmonic synthesizer need a filter?

Don't ask me, ask Clark Ferguson.

Seriously, the sound is extremely raw and the single harmonics are no pure sine waves but closer to pulse waves. You have two filter sections, actually, a simple low-pass in each of the Harmonic Generator sections, and then a multimode VCF with independent outputs for LPF, BPF, and HPF, which can be modulated using a very simple envelope or an LFO.

@bitexion: Errors remain errors, no matter how much time has passed.

Eeeuuuwww.
It's so hard to find a good hardware additive synthesizer with a great interface.

The Interface is lovely. If only they had incorporated some more modulation routings (like oscillator crossmod), more elaborate envelopes, another LFO, and a ringmodulator...

There is some RMI Harmonic Synthesizer stuff to be found here:
