Swamped

The vague outline of an idea comes to you. If you just had a metronome... well, you may have an idea for how to get one. If the Host has one on board, that is.

Ran a test. Volume seems fine, but playing multiple sounds in sequence causes them to run together in the amplifier. I think I can correct this by using a metronome timer to introduce a delay until each sound plays in full.

You send the note off, and before long a metronome arrives, with a response note.

I'm curious as to how that problem came about. Regardless, I look forward to seeing the final product.

You're fairly sure he's gotten suspicious of you by now, but while your request was unusual, it probably seemed harmless enough. He probably couldn't think of anything you could do with a metronome to help you escape.

In fairness, you're not entirely sure this is a viable plan. But it's the best option you can see.

You take a few moments to think about the details of how this device is going to work.
