An unexpected visitor from 1999; The Waldorf Q in the "Halloween" colour scheme. The Q is a DSP-based virtual analogue synthesizer from the era when knobs, sliders and analogue sounds came back in fashion, but when digital engines were able to handle the reproduction, provide comprehensive control over them and add newer features. The Roland JP-8000 and Korg MS-2000 are two other examples of this era of instrument. The Q has three oscillators (plus two sub) per voice with your usual pulse, saw, sine and triangle, but the first two oscillators also have two "alt" settings that are wavetable generators somewhat in the territory of synths like the PPG wave. Not overly surprising as Waldorf founder Wolfgang Düren had been a distributor for PPG in the 80s. In fact, the dual multimode filters even have a dedicated "PPG" setting along with 24db/12db low pass, high pass, band pass, notch and comb.
