1. Fruity Loops has come a long way over the years, and I have to admit I haven't used it in about 6 years (when it was just an audio step sequencer), but as it seems to be a fully featured DAW now, so, you are aiming to write notes on, say MIDI channel 1, in FL, and then with your Virus Multi-Single mode, channel 1 will pick up those notes. FL ch2 to Virus Ch2 etc..
2. The FL Manual?
3. you've had your virus for a year, and now want to know where to start?!! Well, as they often rudely say in music production forums RTFM!! =D , but seriously, the Virus has a very excellent Programming Analog Synths guide (in adition to the manual), full of step by step tutorials on how to reach a sound from scratch, (if you didn't get this, I'm sure it's available from Access). That would be a great start.
Beyond that, lets firstly say it's a beast of a synth (I have an Indigo II - same as Virus C), and you should be able to pretty much get any sound you want from it, with practice. Sure, it won't do some sounds, but it is its own species, and therefore has its own, unique character, and should be respected for that. And the more you know it, the more you get out of it... I'm still finding new things, and expect to for as long as I live!! (God forbid I would ever have to sell it!!)
4. Yes. Midi channel 1 - lead 1, MIDI 2 - lead 2, MIDI 3 - lead 3... etc... up to 16!! .oh yeah, well there is the voices thing. The amount of channels that will correctly play is limited by the polyphonic capabilty of the synth. Luckily the virus allows you to set the priority (high or low) for each channel. You won't realistically run into problems there till you're using around 5 - 7 channels.. be aware that having chorus, or phaser, or all Oscillators on uses more voices. Only use what you need on each channel
ShortBus - the word 'Combinator' only makes any sense to someone who uses Reason! which not everyone does. Well I don't anyway.
