Two Voice Pro Analog Synthesizer (Black)


The Tom Oberheim ‘Two Voice Pro’ is a two-voice analog synthesizer with a keyboard, several patch-points and a mini-analog sequencer with memory features. Each voice has a separate set of parameters, that way each of the SEM voices can produce a totally different individual sounds. An update to the Classic Two Voice Synthesizer.

In 1975 Tom Oberheim took his first synthesizer the monophonic SEM and created his the first compact, programmable and polyphonic synthesizer for Oberheim by coupling two SEM modules to a 37-note keyboard and a simple analog sequencer. This became the original vintage Two Voice that has now been reproduced with some added features and enhancements. The all new and still familiar Two Voice Pro now understands MIDI with a sequencer that can be synchronized to MIDI as well.

Each SEM voice has two sync-able VCOs with pulse and sawtooth waveforms, a multimode filter, two envelopes per voice, and an LFO each. 


  • Two-Voice Analog Synthesizer based on the Original Oberheim Two Voice Synthesizer designed by Tom Oberheim
  • Mini-Sequencer is enhanced - you still generate a sequence with the knobs ( up to 16 positions ) but you can store sequences from the knobs into flash memory (up to 99 sequences stored)
  • Two sequences can be played simultaneously (or play one sequence while also playing on the keyboard, like the old one)
  • After sequences are stored in flash memory, you can edit them to add 2-way, 3-way or 4-way ratcheting and you can program the gate length from zero (like a rest) up to almost the complete step length
  • Sequences can be chained into songs, and each step in a song can be programmed for sequence number, transpose amount and number of repeats
  • Sequencer syncs to Midi Clock
  • Keyboard outputs velocity and pressure
  • Each module (both SEMs, Mini-Sequencer, Keyboard Control) has mini-jack patch points (56 patch-points)
  • Pitch and Modulation wheels
  • Pan pots
  • Headphone output
  • Separate Vibrato LFO
