An update on Reason, Jez -- I just got it, and I must say I absolutely
love the interface. The way they've laid it out is very clever -- just like a hardware setup, with mixers and things being plugged into each other and the sounds laid out very logically. Well done to the people at Propellerhead!
However, that said, I'm afraid I cannot give up FL for Reason, as much as I would be interested in pursuing it, for one fundamental reason. Reason does not support VST synths, and VST synths are essential for the work I do. For example, Peter Howell made his Doctor Who theme bassline on the Yamaha CS-80. To recreate it, I use Arturia's CS-80V VST soft synth, which is based on the CS-80. That synth is essential to getting the sound so close, and denying myself the use of VST synths takes away too much control from me and therefore I can't use it.
Hopefully Reason 4 will support VSTs...
