Oberheim Four Voice - Rosen Sound Demo

Demo of our Oberheim Four Voice FVS Synthesizer

This in our opinion is one of the finest synthesizers ever made in terms of overall sound. The features are of course many and the synth as a whole is very flexible and powerful, but the sound it outputs is nothing short of mesmerizing.

The FVS features 4 Synthesizer Expander Modules (SEM) each representing a polyphonic voice. This means for one patch, each SEM must be setup identically. This may seem like too much, but it's actually a very enjoyable process that causes you to think different about the patch your making, the polarity of your modulation per voice, and subtle differences you can set.

The synth can also be used in a powerful unison mode, allowing each SEM to be adjusted separately for a crazy 4x dual oscillator synthesizer each with a multi mode filter to be fired at once.

Each SEM is as or more powerful than your standard mono synth, featuring 2 oscillators with saw and pulse each, PWM, FM, 1 LFO, two EG's, a bi-polar filter modulation control, and the sweetest Oberheim filter ever made featuring a bandpass filter and a sweepable LP-HP filter. These filters are special in the way that when the resonance is turned up, there is no loss of volume or low end.

Additionally, our FVS is an early model with no programmer (a feature loathed by many anyway). Instead, it features 2 dual mini sequencers with a common clock available. This means you can do 8-step 4 note poly sequencing between the four SEM's, or split the keyboard with one sequencer playing 1 SEM and 3 note chords on the other side of the keyboard.

Functionally, our FVS is very much in tune and has been stabilized to survive travel and tuning consistency. It is in tune as soon as it's turned on, and we provide a quick start guide for our rental customers to learn how to easily program and tune the machine.

Our FVS also features MIDI in via a modified YARN's module installed inside. This allows through basic midi and if desired (more complicated) midi scripts to play it polyphonically (default on boot), sequence each SEM assigned to a separate channel (enabling MPE), or played in Unison. All of these features can be harnessed by utilizing SYSEX or the Yarns editor, all which is provided on a thumb drive for rentals.
