The OB-E is our take on the legendary 8-Voice. More than just an emulation, the OB-E offers a unique musical experience. Sounding HUGE, it takes the iconic Synthesizer Expander Module (SEM®) based 8-Voice (a.k.a the EVS) into new sonic territory via a raft of enhancements and additions.
The concept of the 8-Voice is actually very simple; based around a single SEM containing two VCOs with Pulse and Sawtooth waveforms, two ADS Envelope Generators, one LFO, and a magical Multi-Mode Filter. In isolation each SEM is monophonic, but in the 8-Voice, because there are eight SEMs triggered by a polyphonic keyboard, you have a superb eight note polyphonic synthesizer.
While simple at heart, the OB-E is, to our knowledge, the first virtual instrument with complete per-voice control. This unique Octaphonic architecture offers fresh and exciting creative possibilities to music producers, composers and sound designers for the first time in the digital realm.
Note OB-E is Mac only at this time.
600 factory Patches saved in various categories and with tags.
The MODULE - FRONT
The core building block of the OB-E is the SEM. Each SEM has 3 Oscillators, a Multimode Filter, 2 Envelopes and modulation controls.
The MODULE - REAR
Each SEM has both front and rear panels. The rear of each allows us to extend the range of functions programmable in each SEM.
The OB-E groups SEMs 1-4 into the LOWER MODULE mixer and SEMs 5-8 into the UPPER MODULE mixer. Individual volume and pan for each SEM can be set here along with a MASTER control for each group.
ZOOM a SEM to enlarge the interface for detailed editing. ZOOM places the front and rear of the selected SEM side by side within OB-E.
An Augmented yet Authentic Instrument
We’ve painstakingly emulated every section of the synth to ensure sonic authenticity while adding the convenience of software control over those eight SEMs. Mono, Mono Legato, Poly, Unison and Split keyboard modes are all available. Add to this the new VCO3, doubling as an audio rate LFO for each SEM, and a stack of additional performance controls via velocity, polyphonic after-touch and MPE control then you’ll begin to understand the depth of musical possibilities OB-E provides.
Zoom And Group Provide Faster Editing
Programming a polyphonic sound on an original 8-Voice was a daunting mission, the OB-E makes it a cinch. Unison Chords a forté. To overcome the arduous task of editing 8 individual SEMs, the OB-E provides a number of clearly thought out editing controls such as ZOOM which enlarges the selected SEM placing front and rear panels side by side, GROUP (shown above) which enables a SEM parameter change to be applied to all SEMs at once, and OFFSET which functions as GROUP but retains the relative values of each parameter. There’s also a fully resizable user interface. OB-E saves all settings within a Patch but also allows the settings of an individual SEM to be saved as a SEM Preset.
Via the little yellow triangle in the top left hand corner of the UI,
the OB-E allows you to scale the size of the user interface for both reduction and enlargement.
The OB-E offers a range of Global Controls including the all important GROUP edit mode. When GROUP is selected, the parameters knobs of OB-E glow green indicating that editing one parameter on any SEM is mirrored across all SEMs.
The OB-E plays in multiple keyboard modes including mono, polyphonic & unison. The keyboard can be ‘split’ with notes lower than the split playing SEMs 1-4 and above the split SEMs 5-8. Additionally, SEM 8 can be allocated to the SEQUENCER giving 3-way playback possibilities within a single Patch.
The OB-E SEQUENCER contains an extensive range of controls and functions. It triggers either monophonically or each SEM sequentially.
The OB-E analogue style delay that can be routed to the UPPER MODULE, LOWER MODULE or both.
Creative Sequencer & Stereo Delay
And that’s not all! With the original MS-1 sequencer as a starting reference point, we’ve added an extremely comprehensive and creative 8-step Sequencer providing a flexibility and fun-factor unavailable via the original hardware. In keyboard Split mode with the Sequencer routed to SEM 8, the OB-E provides the ability to create a complete three part soundscape within a single Patch. An all-new routable Stereo Delay provides sonically complimentary effects.
Finally, we’ve complemented our instrument with 600+ factory Patches designed by Dave Spiers and a roster of brilliant sound designers. Even better, each Patch has been tagged, categorised and is quickly accessible from the OB-E’s librarian (arrow navigation friendly).
