Thanks for your feedback. Unlike your 5-piece band, entire premise of my show is that it's completely automated since it's a one man show. I simply can't do everything at once and therefore rely upon the sequencer to enact the changes I've told it to make at the appropriate times. Bringing an extra person along to run lights and/or sound would be great but isn't an option at this point.
For those considering my path: I think as a solution I'm going to purchase the Elation DMX Operator 192 Controller. A 3U rack mount, I can program a large number of scenes & banks which can be triggered via midi and even tweak the pan/tilt of the scanners depending on the setup at each venue. Also, a midi control signal sent to the lights during the sequence will allow them to switch triggering to an audio feed from the mixer thus giving me even more lighting options and less programming work to do. Plus the entire show can be backed up on either a USB stick or into my PC.
