Former classical pianist seeks advice and opinions on getting started
as electronic music hobbyist. The only stipulation is that I want to
be able to create "new" sounds, not just play around with sounds I get
off a CD.

Questions that came up in previous discussions:

Computer with midi controller vs. keyboard with built-in sequencer?
If keyboard, relative merits of different brands. Features to look
for?
If computer, Mac vs. PC?
Relative merits of software by Sound Forge/Cakewalk/Propellerhead/NI?

Any advice is much appreciated!
