some setups I use;
FL as multi vsti ( asio ) through SX + VST/i's
FL as multi vsti ( asio ) through Logic + VST/i's
FL rewiring Reason + VST/i's
FL + VST/i's
FL + VST/i's + MIDI
FL + VST/i's + MPC2KXL
FL + VSTi/'s + MPC2KXL + MIDI
Or simply just FL
Reason rewired to FL
Reason rewired to SX
Reason rewired to Logic
Simply just Reason
Logic + VST/i's rewiring reason and FL as multi vsti.
Logic + VST/i's rewiring reason and FL as multi vsti + MIDI

Logic + VST/i's rewiring reason and FL as multi vsti + MPC2KXL + MIDI
Logic + VST/i's rewiring reason and FL as multi vsti + 2xMPC2KXL + MIDI
Logic + Hardware/Instruments
Or simply just Logic
Fasttracker or Renoise
Fasttracker or Renoise + MIDI
Akai os 1.14
Anything with MIDI means no internal routing, both software and hardware is been sent to the console via patchbays. In this setup I'll exclude the use of vst fx to prevent blending emulated algorhytmns with analogue dynamics. It's a personal preference but those prefer plugins can send this to the auxileries on the console when having the proper protocol/farmcard. Also, the smaller the setup involving midi, the smaller the console ( A 01v is very practical thing and easyly intergrates with Cubase or Logic and comes with some good dynamics ).
What does this all mean ? Programs kids buy are crap, look at what major studio's use and you should have the sense to understand that what they use is something you can build and rely on, giving you the features to your ideas to work. What you'll find is ( AND I MEAN SOFTWARE, NOT THE RIGGS THAT GO ALONG ) PT and Logic to be in most major studios. This is due their adaptive capabilities and mostly rock solid pc's required to runn on. Anything besides these programs arent less capable or unprofessional, they are not allround dedicated or lack "someting" that would make a studio/setup less flexible to work with. I wont say which program would be "inadequate" because that really not the issue untill you runn a 300K studio and have a diversity on clientel demanding huge flexibility.
Reason is like a plugin, this due the fact it only receives midi input. I cant rely or really build on this, just pre-production and rewiring it to a platform can be fun/give it some more ptoential, but there plenty of other methods being more intuitive and delivering somewhat better quality, which is naturaly far more appealing. If you're starting out it's a great/cheap thing to learn the basics of simple patchwork of hardware, score editing and the rules of synthesis. The learningcurve is longer since hands on handling of real hardware is for more obvious handling for a noob then staring flabbergasted at a screen with tonns of buttons, knobs, sliders, displays and all the numerous function together in one program. I also find it's soundengine a little thin, making it sound a little plastic. Best feature is the Redrum, no doubt.
FL encorperates all functions, has an extended instrument/voice editor, Midi I/O + sync, very good rendering engine, warm characteristics , export to flp,zip,wav,mp3 up to 320K. LC options, multitrack recording, rewire host&client, multi vsti, vsti/dx support, a dope speech engine, slicer, sample editor, pianoroll and stepeditor ( 786 ppq ). Any oldskool bedroom techie loves this if worked with trackers in the past and it fits in any environment except mac ( at least not that I know of ). It's a different approach then the logic/cubase environemt which are basicly the " same ", but I use to fix a track with a tracker in 15 minutes ez, fl with the right experience is exactly the same gameplay.
Logic is the ideal platform for a hardware/software environment which is less biased at use for VST ( although that's not really a problem except that Logic 6.0 is mac only meaning no vst support ). Logic lets you taylor your use of midi gear and audio signals to the appearance that suits your ideal environment. And I mean softwarematicly, to program how the environment should work your handling. It takes sometime to get the insights together on Logic, but when you do it's really ...logic.
It looks ugly, not as nice as sx, but then again this saves my a lot of cosmetic cpu draining. The rendering engine is to be doubted since lots people compare with PT. I can only say it's relative, hardware mostly decides in situations where you can draw a conclusion on what is better, however, most people wont relate to these conditions. PT relies on Digidesign hardware, Logic depends on nothing but the program itself ( not talking cpu's ).
SX/Nuendo I find nice with vstI only producing, I consider it the vst biased versions of the o-so succesfull cubasis platform but now simply interfaces with anything emulated. I do find the interface tiresome to work with at times, the fx giving a lot of latency but if you keep the approach to producing with sx simple it very efficient. I've been using 1.0 though, since I dont work with it that much.
I have no comment on PT, not into it, same for Cakewalk Sonar, but I bet i can walk away with it in 30 minutes. It's all basics eventualy.
