"An oscillator into a filter is a staple of subtractive synthesis. But what about the other way around?"
OBERHEIM FOUR VOICE FVS-1 (Restored by Synth Tailor Electronics)
video upload by Synth Tailor Electronics
"Here's the Oberheim FVS Four Voice that just underwent a very lengthy overhaul and complete restoration. We ended up spending months on a very faulty programmer, but in the end it turned out excellent! Portamento modification was implemented, to have a way longer portamento rise time.
The Oberheim Four Voice was the first commercially available polyphonic synthesizer that came out in 1975. By utilizing multiple SEMs (Synthesizer Expander Modules) and a digital scanning keyboard, this instrument allowed the musician to play up to four keys at a time, where each key controlled a complete, true analog synthesizer. Each voice was completely independent and could be programmed to have the same setting or different settings, which allowed creation of massive, realistic orchestral sounds.
The assignment of key depressions to SEM voices was controlled by selecting different modes in the keyboard electronics section of the instrument. This allowed both polyphonic operation, as well as having all SEMs play together in unison. Another unique feature of the keyboard electronics was the ability to select true, polyphonic portamento. To enhance the musician's ability to change the overall sound of the instrument, the patented Polyphonic Synthesizer Programmer was also available. Additional features included the ability to control the output level and left-to-right panning of each SEM in order to create a powerful stereo sound field, and cassette interface for storing different settings."
Roland JD-800 | Soundpack "DAWN" - No talking 17:00 minutes
video upload by xu.sounddesign - dirk rohde
"This is soundpack 'DAWN' with 64 ambient patches designed for the Roland JD-800. There are more demos of this cool soundpack.
All in all there are 64 ambient sounds in the package with smoking pads, grainy strings, organic drones and deep textures.
No external effects were used in the demos. All effects are internal effects of the Roland JD-800. No other hardware was used. No compressor, no limiter, no equalizer, nothing, but the pure JD-800.
I designed all the sounds myself.
If you´re interested in these 64 sounds, please send me an email (xu.sounddesign@gmx.net). Please check your spam-folder."
