Pro 3 Mono/Paraphonic Synthesizer

Sequential Pro 3 Mono/Paraphonic Hybrid Synthesizer

The Sequential Pro 3 Mono/Paraphonic Synthesizer is a 37-key Synthesizer with a Hybrid structure. As the successor of the popular Pro 2 Synthesizer, the Sequential Pro 3 is located in the flexible range of a medium Modular System. The Pro 3 can be played as either as a single voice Monophonic Instrument or as a Paraphonic, for 3x voices.

The features of the pro 3 are many; 2x Analogue Oscillators (known from the Prophet 6 and OB-6), a Wavetable Oscillator (containing 32x Wavetables with 16x Waveforms each, including Wave Morphing) and a Noise Generator form the basis of a rich and flexible sound. The Sequential Pro 3 shines with 3x selectable, Analogue Filter classics (Prophet 6, OB-6 and Moog) to alter the rich basic sound. The 2x Prophet 6 and Moog Filters are resonant and can be distinguished from each other by character. The OB-6 Filter is a real State-Variable Filter and can be faded over continuously from Low-Pass to Notch to High-Pass, or alternatively the Band-Pass can be activated. The selected Filter is further enhanced with its own Drive parameter. The signal path also includes a dual effect block that generates Delay, Reverb, Chorus and Phaser. In addition, the Sequential Pro 3 offers a more powerful Analogue Distortion and a tuneable Feedback line.

No fewer than 3x synchronizable LFOs, each with 5x Waveforms and 4x loopable Envelopes, give the sounds in the Sequential Pro 3 an undeniable movement. Thanks to the extensive modulation matrix with 32x entries, LFOs, Envelopes, Touch-Strip, Sequencer and various Controllers can be assigned to almost any parameter. This allows the Pro 3 to have a fixed Signal Path, but still provide the kind of modulation flexibility that you would otherwise only find in a Modular System. Of course there is also a Sequencer with 16x tracks on-board, which can automate not only notes but also all parameters. You can also save 4x patterns per sound, or create a longer one with up to 64x steps. Various playback directions and trigger modes complete the tool-kit of Sequential Pro 3.
