PPG Wave 2.3
The German made PPG (Palm Products GmbH) Wave 2 series of synthesizers are incredibly great sounding analog/digital hybrid vintage synths. They use digital samples of wavetables and feature analog VCA envelope and VCF (filter) sections for a classic and warm sound. The Wave 2.2 has oscillators that can generate over 2,000 different single-cycle 8-bit digital waveforms! Covered by knobs, the Wave still looks analog and this comprises the "Analog Control Panel".
More complex and new-wave editing of the wavetables and samples is covered by the "Digital Control Panel" where there are several key-pad buttons and an LCD screen. Another familiar treat to analog junkies is the inclusion of an 8-track sequencer which features automation of pitch, loudness, filter cutoff, waveforms and more. A cool feature - its onboard sequencer will also record any filtering and wave changes, in real-time!!
The more commonly encountered Wave 2.3 (pictured) followed the 2.2 and had enhanced sample-playback capabilities. The sampler was pretty full-featured for its time and included upgraded 12-bit digital waveforms, Fourier analysis and linear playback of samples. The 2.3 model also featured 8-parts multitimbrality and MIDI implementation. The PPG Waves are know to create excellent pads, brass and bass sounds.
