Kurzweil innovates with 76-key versions of PC4 performance controller and SP6 piano
Just when you thought Kurzweil was running out of ideas someone suggested removing an octave and we have the entirely new and yet the same PC4-7 and SP6-7.
76 keys
I’m just teasing really. It’s funny because when I wrote about the PC4 last year I said “Although knowing Kurzweil there will be a 76 note and 61 note version with a synth-action keyboard along before too long.” and here we are!
Both of the machines are scaled down slightly to 76 keys of semi-weighted action with velocity and pressure sensitivity. This makes them lighter and more gigable that the larger hammer action and weighted keys of the originals.
Mega synths
The PC4-7 is the same uber controller keyboard with 16 zones and 36 controllers. Oh, and a huge sound engine featuring VAST, FM, KB3 and VA1 forms of synthesis and emulations with up to 256 voice polyphony and 2GB of sample space. Add in the 16-track sequencer and this is one heck of a workstation keyboard.
The SP6-7 is marketed more as a piano but still has 4 zones, 20 controllers and the same sound engine just with 128 voice polyphony.
VAST (Variable Architecture Synthesis Technology) is a powerful DSP synthesis engine which incorporates waveforms and samples through multiple forms of synthesis processing. The FM engine is a full-on 6 Operator digital synthesizer. KB3 is about Kurzweil’s emulated organ technology and VA1 refers to their acoustic modelling and emulation engine. These are meaty and frequently under-appreciated machine – especially by me!
So there’s nothing special going on but Kurzweil has got around to expanding their range of keyboards and broadening the appeal – nice one.

Just to be specific, PC4 and PC4-7 are the SAME except for the 88 to 76 key keyboards. That is with all the same features – no loss and no gain?
That’s my understanding, as far as I could make out from the specs on the website.
