Ahhh, but since I insist on automatic convenience, the interior 'wiring' is designed so that you don't even need the extra switch. Just turn it on...and IT EXPLODES! Which, in a sense, is the answer to many synthesists' prayers: auto-programming in a modular. It's a technical innovation that is guaranteed to be groundbreaking...probably for your funeral if you're standing over it when you power it up, actually.
It's also auto-tuning and totally drift-free. I guarantee that whatever extremely momentary noise this emits will be perfectly cent-accurate compliant to some sort of scale in some way or another. Yet another horrible and long-vexing technical issue SOLVED!
