PPG | Wave 2.3
The PPG Wave Synthesizer, is no doubt considered one of the most respected high-end synthesizers of the 1980s. developed by Wolfgang Palm. Its featured on countless records, and it inspired a whole generation of producers, composers and listeners.
The 2.2 offered two oscillators per voice which opened up a whole new realm of sonic possibilities because two separate wavetable sounds could now be combined.
The next step was the 2.3, in which the hardware was changed, and there were two modes. One was the digital oscillator mode, and the other was the sampler mode where you could play through the entire memory in a linear fashion, like on a sampler. Of course, you could transfer waveforms from one mode to the other, which was very interesting. You could sample something and then take out periods, make Fourier analysis, and put that back into a wavetable.'" ...Not only did it allow linear playback of samples in memory, but the resolution of those samples was increased to 12-bit, which greatly improved the Wave's sound quality. The 2.3 was also multitimbral, sounding up to eight different wavetables at once. And it had MIDI, the implementation of which was a sore subject as far as Wolfgang Palm is concerned. 'PPG had an 8-bit parallel bus system before MIDI came out,' he says, 'because we had to transfer samples from the Waveterm to the Wave - a very thick amount of data. Our bus was much quicker, so we didn't like MIDI very much. It was okay for some things. The problem was, MIDI was a second interface that we had to use and support. It took much more effort to redesign our existing machines than it would have been to implement all the MIDI capabilities from the beginning.'"

|Velocity||As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key.||Aftertouch||Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.|
