Cyrus MonoX300 MC-Bus Issues and Accessory Testing

Whilst working on my trigger accessory it became clear that the Cyrus MonoX300 amplifiers MC Bus operation is decidedly flaky.
Here I make some changes to my accessory code to try and overcome the Cyrus shortcomings. A simple automated test is then developed to run some repeatability tests and spit out the results.

I do not use the MC Bus on my multi-box Cyrus set up. I simply let a music signal to wake the Power Amps from switch on from Pre-amp.

That works for some models of power amp and certainly the newer ones including the MonoX300's. However, the aPA and MonoX amps don't have the music sense feature.
