PPG | 390 Drum Unit
The PPG PRK is a velocity sensitive 72 key master keyboard to be used only with the PPG synthesizers.
The PPG PRK was created for a number of reasons; firstly many PPG owners wanted to have velocity sensitivity when using their PPG synths - the PPG PRK offers this.
The PPG PRK also offered optional voice boards to be inserted into the unit.
The PPG PRK FD was the second and last master keyboard from PPG.
It still offered 72 keys (6 octaves), a nice velocity sensitive keyboard and resembled the original PPG PRK in many ways.
It also included MIDI - and had one MIDI in and four MIDI outs. So you could control not only PPG Components with the PPG PRK FD - but also other MIDI devices.
The PPG PRK FD has a 5.25 inch floppy drive (hence the name FD = Flopp Drive) and could - unlike the PPG PRK - be used to load samples, sequences, programs and wavetables to other PPG components.
So a musician could sit back home in the studio creating music using the PPG Waveterm / PPG Wave 2.2, PPG Wave 2.3 and/or PPG EVU system - and could leave the PPG Waveterm back home when going on the road.
The PPG PRK FD uses the much faster Motorola 68000 processor as opposed to the Motorola 6809 used in the PPG PRK.
