This Q is fully functional and in great condition. With 16 voices and 16 multitimbral parts, the Q is well adapted for reliable live use. Waldorf's excellent analog sound emulation is complemented by sophisticated yet familiar analog-type controls and parameters. There are 3 oscillators per voice, 3 LFOs with ramp, sine, square, etc. and 2 12/24dB Filters (Low pass, band pass, hi pass, notch, comb, ring mod and more). A powerful arpeggiator and sequencer are also on-board for creating complex accompaniment or arpeggios. There are 58 knobs to aid you in tweaking away at creating amazing sounds! All knobs and edit parameters are MIDI controllable. The Waldorf Q is topped off with 8 effects processors (2 per sound that include Chorus, Flanger, Phaser, Overdrive, AM, Delay, Reverb, etc.), 2 analog audio inputs, 6 outputs and 1 S/PDIF output (44.1kHz / 48kHz switchable) and vocoding capability. The Q is a professional-grade virtual analog synth that combines the raw power of analog synthesis with modern technology, stability and creativity.
