An ultra-affordable homage to that iconic synthesizer with all the features of the original and then some, the PRO-1 lets you conjure up virtually any sound with incredible finesse and ease. With its pure analog signal path, dual authentic VCOs with 3 selectable waveforms, plus extremely flexible VCF and VCA filters, the PRO-1 is sure to become one of your favorite keyboards. Owning the PRO-1 is like having your own personal time machine, enabling you to embrace the past – or make your imprint on the future! 

Great care has been taken in engineering the PRO-1, including the true to the original analog circuitry, legendary VCO, VCF and VCA designs, all of which combine to make it easy to recreate the classic sound performance. This highly-focused attention to detail is what gives the PRO-1 its ultra-flexible sound shaping capability, which covers everything from super-fat bass and lead tones to stunning effects – and all the way out to the otherworldly sounds of your imagination. 

The inspired synthesizer tracks laid down in the 1980s and ’90s are etched in the annals of progressive rock, wave, EDM and synth-pop music forever, making them truly classic in every sense of the word. The PRO-1 lets you recreate all of that magic – or design incredibly fat and original sounds that will make you a legend in your own right!

PRO-1’s 3340 Voltage Controlled Oscillators (VCOs) provides your choice of up to 3 simultaneous waveforms (Oscillator A: Sawtooth and Pulse, Oscillator B: Sawtooth, Triangle and Pulse), with a selectable range of 4 octaves. The VCOs can be modulated via the envelope or the low frequency oscillator (LFO). Performance is further enhanced by the Mixer section, which balances the levels of the internal VCOs and noise generator. This amazing flexibility gives you the tools to be your creative best. 

The very heart of PRO-1’s sound is its classic 4-pole filter, which lets you freely experiment with the Cutoff Frequency, Resonance and Envelope and Keyboard amount, and full complement of ADSR (Attack, Decay, Sustain, Release) controls to dial in the perfect sound. PRO-1’s filter Mode switch can be set to either Lo- or Hi-pass for selecting the range of your choice.
