Increase polyphony and comment out debug logs

Browse Source 
Updated the polyphony level from 10 to 20 to enhance sound capability and commented out several debug logs for cleaner console output. Additionally, commented out a block of code related to sine wave modulation that appears unnecessary at this stage. The console log message for registering the processor was slightly modified for consistency.
