Designed in collaboration with Dave Smith Instruments, the Pioneer Toraiz AS-1 is a monophonic analog synthesizer based on the discrete analog circuitry of the Prophet-6 synthesizer, bringing new creative possibilities to the studio and the stage. The intuitive controls include parameter knobs, which allow for subtle or dramatic changes to the tone of your music to create a personalized sound. Additionally, the on-board, touchpad-style keyboard and slider allow for sound manipulation on the fly during performances. The instrument features two voltage-controlled oscillators (VCO) with continuously variable waveforms including triangle, saw, and pulse wave shapes. There are two voltage-controlled filters (VCF), a 4-pole, resonant low-pass filter that can self-oscillate, and a 2-pole resonant high-pass filter. Additionally, there are two ADSR envelope generators, a VCA, and an LFO. For effects, the AS-1 inherits the Prophet-6's dual FX engine and includes a bucket-brigade delay, ring modulation, chorus, phaser, and digital distortion. There are 495 preset programs organized into 10 banks, with each program offering its own 64-step sequencer.
