Start: 9:00
- Finished setting up the test to have the new midi controllers added
- Tried it there was still a tremendous amount of white noise. I turned off the power supply and noticed that the power led on the Midi shields was still on from the Arduinos power. I looked up the different Arduino pin modes and found that if its set to OUTPUT, it can put out as much as 70ma. INPUT mode, on the other hand, has high impedance so it produces much lower current. The reset pin has to be set HIGH or the chip is in off mode, so I tried switching it to INPUT mode so it didn’t output excess power. This resulted in the white noise being almost completely eliminated and the chip’s power led now turns off when the power supply is off. For some reason, both examples on the sparkfun page show this pin being set to OUTPUT. I posted this solution on their page so hopefully others will be helped.
- Setting multiple channels to play the same note on the same instrument gives it a fuller sound.
- There was a problem that I had with the end of the buffers data. Clearing the buffer after each import solved it.
- Changed the volume to accept doubles between 0-100 instead of decimal percentages.
- Added the an instance of the interface to the main. Was able to get the pressure sensors to show up.
- Changing things around so that the simulation runs through the computer instead of autonomously on the arduino.
