Are the audio files (Loops) streamed direct from disc, or do they need to be loaded into Ram first.
Is the CPU bespoke or standard computer
Also don’t forget that 95% of arrangers are bought by Home Players, where ease of operation is paramount.
From what I have heard so far most of it sounds great, so cant wait to hear what it really sounds like, when I get to try and hear it live. (Mp3s are great for starters, but unless you try and hear it live you haven’t got a cat in hells chance of really knowing what it sounds like)
