QUADRO 1.0

QUADRO 1.0

A four-section performance synthesizer for the M-VAVE FM-1, after the ARP Quadra. First release.

What's in it

• Four sections at once: bass (electric and string), string ensemble with three-phase chorus, poly synth (or paraphonic, like the original) and a two-oscillator lead, across a split keyboard
• Phaser, reverb and delay: a 14-stage phase shifter on any section, plus a reverb and a ping-pong delay that follows MIDI clock
• One-finger chords: nine chord shapes from a single key, with the root on the bass (CH BASS)
• Sequencer: up, up/down, down or random over held keys, 1–3 octaves; syncs to MIDI clock (1/4 to 1/32, with triplets) and can send clock
• Pressure: the FM-1's pressure-sensitive keys bend the lead or open its filter, with adjustable sensitivity
• 68 programs: classics, paraphonic, sequences, chords, one-finger band sounds and tricks from the original
• MIDI in and out over USB, Bluetooth and TRS: notes, bend, mod wheel, sustain, CC 74, pressure, program change, clock
• Tuned for the FM-1: the bass sits an octave up for the built-in speaker (BASS OCTAVE −1 for the original register on headphones), and runs on both cores
