Pioneer Toraiz AS-1 is a monophonic analog synthesizer that brings new creative possibilities to the studio and the stage. Its intuitive controls include parameter knobs that let you make both subtle and dramatic changes to the tone of your music to create your own personalized sound. Plus you can use the touchpad-style keyboard and slider to manipulate sounds during performances.
Toraiz AS-1 is driven by a fully programmable, true analog synthesis engine based on the discrete analog circuitry in Dave Smith Instruments' Sequential Prophet-6 synthesizer. It also inherits seven onboard effects from the Prophet-6 synth as well as a brand new digital distortion.
Collaboration with Dave Smith
Working closely with Dave Smith himself, Pioneer DJ has created a synth that produces powerful analog sound. Toraiz AS-1 is an ideal addition to the setups of professional and aspiring producers.
Sequential Prophet-6 analog sound
Toraiz AS-1 is based on the same analog filters as Dave Smith's renowned Sequential Prophet-6 synthesizer. It has two voltage-controlled oscillators (VCOs) with continuously-variable triangle, sawtooth and pulse wave shapes. Sculpt your sound using the two voltage-controlled filters (VCFs), a 4-pole resonant low-pass filter that can self-oscillate and a 2-pole resonant high-pass filter.
Full programmability
Use Toraiz AS-1 to create one-of-a-kind sounds using two VCOs, two VCFs and VCA, two EGs and an LFO, then save each sound and its parameter settings as a program so you can instantly access it later.
495 presets
The inspiring 495 preset programs each have a different sound and 64-step sequence that can be edited separately. You can also save up to 495 of your own programs in the five user banks.
Sequential Prophet-6 effects
Be creative with the Prophet-6-derived dual effects engine and use a single effect or pair two together to add extra texture to your sounds. Available effects include delay, distortion, ring modulation, chorus and phaser.
Keyboard and scale mode
Toraiz AS-1 will make sure your performance is in perfect harmony as you perform the sounds you create with the touchpad keyboard or change the notes assigned to the keys using Scale Mode.
Slider
Add dynamic changes to your performance by using the slider to manipulate seven different parameters. Change the pitch of two oscillators, adjust the amount of effects and more.
Arpeggiator
Be ready to experiment: perform a repeating chord pattern and change it in real time, try out different scales, match scales with a track during playback and more.
64-step sequencer
Give your performance the edge with the 64-step sequencer. Step record patterns, change musical key, edit the sound without editing the pattern — it's all possible.
Creative DJ setup
Create even more complex patterns by connecting Toraiz AS-1 synth to Toraiz SP-16 live sampler via MIDI. Or take it to the booth and connect the sampler to your DJ setup via Pro DJ Link: CDJs play the track, Toraiz SP-16 adds loops and one-shots, and Toraiz AS-1 generates unique analog leads.
