2 patch cords = $4.99
Ableton Live Standard = $499
I'd think with all the interest in Eurorack modulars, hardcore synth folks wouldn't find the concept of using two patch cords so alien 
Or REAPER for $60, or if you are happy to be a little bereft of morals, you can download the demo which is the full product with no restrictions, which even after the 'demo period' expires will continue to function with no restrictions for ever and a day.
I just don't get the logic. The original question, in case it's been forgotten by now, is about (supposedly) not being able to do real-time recording of an instrument in SONAR. But unless you have only a 2x2 interface, which seems inadequate for most professional applications anyway, you can do it with two patch cords. Why would you need to spend $60, leave the SONAR environment (remember the original question), record a track, then bring it back into SONAR? Yeah, I was brought up with modular synths and patch bays so patch cords aren't an alien concept to me, but still...
