“Unique sounds like syrup with dirt kicked into it. If Bootsy Collins, Roger Troutman and Daft Punk would have met up in Studio 54 to create a soft-synth, for sure something like Unique would have come out of it…” Sound & Recording Mag Unique was made for fun and vibes: Analogue sound, intense modulation and a killer set of features, delivering an amazing sonic spectrum that’s full of character: Classy sounds, powerful, warm… sometimes gritty. Each of the 2 oscillators offers a selection of 5 waveforms: sawtooth and pulse waves are here, along with noise, triple saw and triple FM waves. There's also an additional sub-oscillator strapped into the master section for added oomph. The internal controllers will bring in the dynamics: an LFO and an envelope, there's a recordable XY field & a sequencer. Use these to modulate any knob – a simple long tap will do. The sound springs to life when it hits the filter section. Needless to say, analogue high-pass, low-pass and band-pass varieties are in place, along with a comb filter. Standards aside, the actual intention behind this project, the Vowel Filter, also became its outstanding feature: string together two or four vowel formants and play them back in a multitude of ways. Once you’ve built your sound, there’s tons of sound polish in two chained multi-effect units. Features • Sawtooth, Triple Saw, Pulse, Triple FM, Noise with tonal Filter, Sub Sine • 5 Filters with 5 Modulators each • Duophone Arpeggiator • Vowel Filter • Two Effect Sections • Ableton Link Kit • MIDI Learn & Host Automation • 300 groovy presets by various artists
