migrating from original SamplerBox hardware

Hi Hayesey,
Thanks for your kind words and contribution - I will merge it soon.

Regarding your observations and assumptions:

• Using a 2B may work OK; used it myself before the features started to develop. It all depends: producing many notes and/or using the sound effects may cause CPU strain (the "hiccups, clicks & plops" mentioned in the FAQ).
  
• The USB DAC should have been auto detected. If you're OK, I'll send you a PM to try some debugging (no hurry, your solution is a perfect bypass).
  
• Good to hear the serial midi works as expected; I've recently updated it to adhere to midi standards. Perhaps your device sends realtime messages (like a clock signal), which the original code misinterprets.
