Sheriff,
Well, I can tell you I paid 2000 dollars + 175 for sales tax = 2175 dollars for my ES7. The mLAN16 expansion board is 300 dollars.
Plus your computer and sequencing software and studio monitors and God knows what else, I'm realizing I am very lucky I am a software developer because I would not be able to afford this stuff if I had a normal job!
MUSICMAN...thanks for your input about your mLAN16. Can you tell me, if I purchase one of these and install to my ES7, will I need any other pieces of hardware? What sequencing software are you using? I've got Sonar4 installed on my laptop, but I have hooked my synth up yet. I'm trying to determine the best road for me to travel down. Thanks!
