The Garritan manages this at a 16 sample buffer without any sign of overload whereas I'd need to up this to 64 for the RC and even then it's touch and go, in particular when the sustain is released which can cause a nasty audible glitch as it tries to release all notes 'simultaneously'. I've just checked this again for both the RC 275 and Garritan CFX using an Audient id14 with its recently improved drivers.

My favourite if unsubtle efficiency test is to hold sustain while glissing up and down the keyboard. Guess it's more demanding than I realised.Īppraised on its own merits I'd agree, the Ravenscroft 275 will perform perfectly well on even quite modest (post 2010?) PCs but depending on polyphony, other performance traffic and other PC duties it can be bettered.

I've never had a problem with it at all on my creaking five-year old system (Core i7, but from the Haswell generation).
