At last, the perfect companion to the Harmonáig, quantizer Saïch is the quad oscillator we’ve been waiting for and it’s completely lush.
It’s defined as a number of animate things massed together in motion. In this case it’s four analogue sawtooth waveforms that can individually and globally detuned for creating chords, unisons and other interesting intervals and transforms.
The main Coarse and Fine tuning knob controls all the oscillators and then oscillators 2, 3 and 4 have their own detune knob to offset them from oscillator 1. They can all follow the main 1V/Oct input or split off into their own pitches if their individual 1V/Oct socket is patched. There’s a sub-oscillator attached to Osc1 which can be a ramp, square wave or pulse with automatic modulation plus there’s a PWM input.
Each oscillator has it’s own digital controlled VCA. This allows for the use of a single slider, CV input and mode switch to control the way the four oscillators are blended together. This is a really interesting feature considering there’s only a mix output and gives you some nicely curated creative options that individual outputs wouldn’t provide. There are four LEDs at the top by the mix output that change depending on the position of that slider – nice!
That same slider can also be used to pull in some intervallic offsets which give us shifting octaves, 4ths and 5ths and it can do some global detuning and other bits of wizardry. And, if you don’t have a Harmonáig or other quantizer there’s an internal diatonic mode with Ionian and Aeolian chord scales.
It blends in beautifully to an Instruó based rack and offers an elegance and unusual range of features that are the hallmark of their modules. The video below spends nearly two hours going into the details. Saïch is available now for £469.
