Product Overview

True Analogue Subtractive Monosynth

Pioneer TORAIZ AS-1

A Formidable Collaboration
Pioneer and Dave Smith (DSI) have teamed up to bring you the TORAIZ AS-1, a fully programmable subtractive monosynth with a true analogue synthesis engine based on the DSI Prophet-6 (the modern reboot of the legendary Prophet-5). It also inherits the effects section from the Prophet-6 which includes Bucket Brigade Delay, Chorus, Maestro Phaser, Ring Mod and the addition of a brand new digital distortion.

Analogue Sound from The Prophet-6

Pioneer TORAIZ AS-1

Serious Power, Serious Heritage
Starting with 2 VCO oscillators with continuously variable triangle, sawtooth and pulse wave shapes, plenty of parameters to tweak and a formidable VCF filter section you can make subtle or savage changes to your patches, and all with the renowned quality known from DSI. They've thrown in a 4-pole resonant LP filter capable of self-oscillating and a 2-pole resonant HP filter along with a 64-step sequencer so its quite a capable little synth.

Huge Preset Library
Pioneer TORAIZ AS-1

Sounds to Inspire
You can save up to 495 presets in the 5 user banks which should be more than enough for the busiest synth heads. Pioneer have also added a feature to recall 13 Quick Programs so your favourite sounds are at your fingertips whenever you need them.

Flexibility for The Future

Pioneer TORAIZ AS-1
Creative Capabilities For Producers And DJs
To add even more flexibility the TORAIZ AS-1 can be connected to the TORAIZ SP-16 live sampler via MIDI, and both in-turn can be connected to a DJM mixer via Pro DJ Link. The scope of this is pretty massive - Imagine a setup where your CDJs are playing your music, the TORAIZ AS-1 is hammering out fat analogue bass and lead sounds while the TORAIZ SP-16 adds loops and other one shot drum samples...all in sync with the BPM of the music playing on the CDJs!

"When Pioneer DJ approached us about adapting our sound engine from the Prophet-6 in order to develop the AS-1, we were enthusiastic. With their expertise and deep knowledge of the live-performance market, we knew it would be exciting. The AS-1 has the awesome sound of a classic analog mono synth. When people play it and hear that sound, they're going to find lots of ways to put it to good use." - Dave Smith

Data Sheet
Features Collaboration With Dave Smith
Working closely with Dave Smith himself, we have created a synth that produces powerful analogue sound. The TORAIZ AS-1 is an ideal addition to the setups of professional and aspiring producers.

Prophet-6 Analogue Sound
The AS-1 is based on the same analogue filters as Dave Smith’s renowned Prophet-6 synthesiser. It has 2 voltage-controlled oscillators (VCO) with continuously-variable triangle, sawtooth, and pulse wave shapes. Sculpt your sound using the 2 voltage-controlled filters (VCF), a 4-pole, resonant low-pass filter that can self-oscillate, and a 2-pole, resonant high-pass filter.

Full Programmability
Use the TORAIZ AS-1 to create one-of-a-kind sounds using 2 VCOs, 2 VCFs, and VCA, 2 EGs and 1 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 programmes each have a different sound and 64-step sequence that can be edited separately. You can also save up to 495 of your own programmes in the 5 user banks.

Prophet-6 FX
Be creative with the Prophet-6-derived dual FX engine and use a single effect or pair 2 together to add extra texture to your sounds. FX includes Bucket Brigade Delay, Distortion, Ring Modulation, Chorus and Maestro Phaser.

Keyboard And Scale Mode
The 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 with Scale Mode.

Add dynamic changes to your performance by using the slider to manipulate 7 different parameters. Change the pitch of 2 oscillators, adjust the amount of FX and more.

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 recording of patterns, changing the musical key, editing the sound without editing the pattern – it’s all possible.

Creative DJ setup
Create even more complex patterns by connecting the TORAIZ AS-1 synth to the 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: The CDJs play the track, the TORAIZ SP-16 adds loops and one-shots, and the TORAIZ AS-1 generates unique analogue leads.
