This is a beautiful synthesizer made by the most respected name in electronic instrument design, Sequential. The Pro 3 is a work of art in hybrid synthesis, combining 2 classic Sequential analog oscillators with a third digital wavetable oscillator for an old school vibe with a futuristic flavor. Although the focus is on being a kick-ass monosynth, you can also push it to three notes for added versatility.
Along with the 3 oscillators, you get 3 filters, 3 LFOs, 4 loopable envelopes, a large 32-slot modulation matrix, and a sequencer. The filters are based on vintage designs and include a 4-pole low pass from the Prophet-6, a Moog-like ladder filter and a 2-pole OB-6 filter. That’s far too much character for one synthesizer and did I mention that you can add your own wavetables to the third oscillator? At the end of the chain is a dual-channel digital effects engine for delays, reverbs, and other time-based effects.
The modulation possibilities are immense, starting with the 4 loopable five-stage envelopes, 3 syncable LFOs with slew, and phase off-set. There are dozens of modulation sources and hundreds of potential destinations. It also plays well with modular synthesizers via 4 lots of CV input and output. The sequencer offers 16 tracks with 16 steps and 4 phrases with ratcheting, variable gates, and multiple playback modes. It also has an arpeggiator.
The Pro 3 is a wonderful example of a premium synthesizer that is a joy to play and will stay with you for a long, long time.
