  • My computer was still having an issue this morning.  I think I found the problem.  Asus has an auto driver update which seems to run whenever windows updates and mess up the processor by running too many threads at the same time.  I disabled this and a couple other things and restarted the computer.  Seems to be running good as new again.
  • Set up the Arduino mega for testing.installed the drivers found in the IDEs root directory.
  • Had to select the firmware type from the list in the IDE.  Selected the old mega first and was getting a sync error whenever i tried to upload a sketch.  I eventually realized there were two versions of the mega
  • The mega uses com port 5 instead of 3.
  • The mega has its own port for i2c instead of using analog ports 0 and 1 like the uno does.  Still am not sure if you can have multiple i2c channels.  I know the way the Wire.h library works, it is actually hard wired to these ports and cannot be changed or expanded.  I don’t think we will need more then 4 rheostats and we might not need any at all if the midi volume control is sufficient.
  • Tried upping the voltage on the 30Watt amp to its upper range as opposed to the lowest functional which is what I usually do.  There was no change in the amplification but the heat sink got hotter.  Decided to just stick with 12 volts.
  • Continued incorporating the midi into the simulation.
