Then I set up a new MIDI track with an output to "ARP2600 V Efx", which appears in the MIDI output list - so that I can trigger things through MIDI. Of course I also use VST automation quite a bit in these situations, and tend to use MIDI only to create a note that holds open gates and triggers envelopes and provide tracking information to the filters and oscillators.
I love seeing photos of studios back in the analog daze where the prevalence of microphones, tape units (both as track input and output as well as reel-to-reel based delay units) and a myriad other effects were plugged into and fed off of modular gear. Organ-styled keyboards were typically the *last* thing that anyone cared about. The really cool thing about using virtual analog synths as effects in today's world is that as soon as you need another Moog Modular or ARP2600 V to cram a drum, guitar, vocal or other keyboard through - you *don't* have to unplug everything and re-patch. You just call up another instance of the plug-in and run with it. It's like having a room full of modular gear sitting off to the side of your studio. How many folks that paid $1000s for their analog gear would like to have that option for a touch more than $300?
