I've been testing it for a few days with the immediate hope of using it on my 8GB laptop. Keyscape is not easy to just install and play on a laptop. 8GB RAM is the minimum....and I have been having problems with that and a very fast PC. Macbook Pro users might fare better with 8GB, certainly 16GB RAM would be great, but that is hard to come by on a laptop.
BTW, I own every Spectrasonics product since the beginning with Stylus RMX, Trilogy, Trillian, Atmosphere, Omnisphere.....I use them all on my studio i7 desktop with 32GB Ram and RME interface. I haven't even started testing Keyscape on the desktop, I really wanted it working for upcoming live use.
With my Lenovo Yoga 2 Pro i7 and 8GB Ram, 512 SSD, Win 8.1 - using Cantabile 3 as a host. This system works great with Ravenscroft UVI, LOUNGE LIZARD and Kontakt live at 128 or 256 samples, but Omnisphere does put a demand on the system.
I'm having glitches in Keyscape at 128 samples no matter what I do.....even at 256 with "Thinning" on and voices set to 14 it will sometimes just choke. Obviously, that is too few voices to play most styles. I've tried 2 different interfaces: USB Motu Ultralite Hybrid and NI Traktor 2 MkII.....Then, ironically, I get best results with the built in headphone jack and ASIO4ALL driver at 256. I just don't know if I can trust this C7 in live performance. The Rhodes seems to be better.
This seems to be the deal with Spectrasonics, great sounds, but high demand on RAM and CPU.
Having said that, The C7 is beautiful, clear, resonant and not as bright as you would expect. Very inspiring to play. The Ravenscroft is a bit brighter....and still my overall favorite over all the other "working" VST pianos I own: Garritan CFX (2nd favorite), Galaxy Vintage D(NI Grandeur), Ivory Italian or American Steinway.
This reminds me a little of the unplayable Quantum Leap Pianos with PLAY interface I bought 6 years ago. Wasted $450. Also, Gospel Keys/Neo-Soul Keys (Rhodes) was a glitch prone, RAM and Processor demanding UVI based VST.
So, if Ravenscroft/UVI can make a very deep player that is very efficient, and includes a bunch of efx, why can't Spectrasonics do the same, since their Steam engine succeeded their using UVI for Atmosphere? Ravenscroft even scaled down the whole library to flac and it only takes up 5GB with 4 stereo mic positions to choose from and mix.
The C7 on Keyscape, even with Thinning feature - as it is now implemented- is not enough to scale it down to run glitch free on most systems, in my opinion. They should really rework some C7 patches to be "lite" versions, with more voices capability.
Any users who have better results, please chime in with your system and settings.
