Tom Oberheim, a legendary figure in the world of synthesizers, has left an indelible mark on the music industry, even if his name isn't always in the spotlight. While he's best known for his work under his own name, Oberheim, he also released some of his most innovative and influential synthesizers under lesser-known brands: Marion Systems and SeaSound. These synthesizers, released during a period of legal and financial struggles, showcase Oberheim's enduring creativity and his commitment to pushing the boundaries of electronic music.
Marion Systems MSR-2
The MSR-2, released in 1994, was a groundbreaking rack-mount synthesizer that captured the essence of Oberheim's iconic sound within a 1U format. With 16-part multitimbral capabilities and complex routing options, it was a significant step forward in the world of modular synthesis. Its unassuming appearance belies its power, and its rarity only adds to its allure. The MSR-2 represented a shift towards rack-mount modules, a trend that would dominate the industry in the coming decades.
Marion Systems ProSynth
The ProSynth, released in 1995, was another rack-mount synthesizer that aimed to capture the warmth and feel of analog synthesis in a digital package. Despite its basic features, including a stereo output, no headphone port, and no sampled waveforms, it offered a unique blend of old and new. With 8-voice polyphony and the ability to trigger each sound via a separate MIDI channel, it provided a level of control and creativity that was still relatively new at the time. Its bass and lead sounds were particularly praised, though it may not be considered a classic in the same vein as some of Oberheim's other work.
tomoberheim.com SEM Pro
In 2010, Tom Oberheim released an updated version of his iconic SEM synthesizer expansion module under the 'tomoberheim.com' banner. This new iteration retained the original's multimode VCF and voice architecture while adding new features such as 21 patch points, a preamp, transposition, and a MIDI-to-CV interface. The patch panel version, in particular, introduced innovative internal modulation techniques and deep interfacing capabilities with Eurorack modular synths, making it a versatile and powerful tool for modern electronic music production.
Marion Systems TVS Pro
The TVS Pro, released in 2016, was a reimagining of Oberheim's beloved Two Voice synthesizer. By chaining two SEMs together, Oberheim created a powerful instrument with a new sequencer module, a two-channel design with 16 steps, and a ratchet mode. The hardware boasted 56 patch points, MIDI in, out, and thru, and six discrete audio output jacks. With performance options enhanced to include unison, duophonic playing, and pitch and mod wheels, the TVS Pro was a testament to Oberheim's ability to blend the past and present seamlessly.
Sequential OB-6
The OB-6, a collaboration between Tom Oberheim and Dave Smith, was a modern take on the classic Oberheim sound. Inspired by the SEM, it featured true voltage-controlled oscillators, a 2-pole filter, and amplifiers, all enhanced with studio-quality effects, a polyphonic step sequencer, and an arpeggiator. The OB-6's hands-on approach, with all its features easily accessible, made it a favorite among musicians and producers. Its 500 factory and 500 user presets, Manual mode for real-time sound shaping, and a four-octave, semi-weighted keyboard with velocity and channel aftertouch further solidified its place in the history of synthesizers.
Tom Oberheim's work under these lesser-known brands showcases his enduring creativity and his commitment to pushing the boundaries of electronic music. These synthesizers, released during a challenging period in his career, have become highly sought-after by collectors and musicians alike, proving that Oberheim's influence extends far beyond his most famous creations.
