Effects Added:
12xx - Change Duty Cycle/Noise Mode:
This effect will change the duty cycle or the noise output mode.
If you are in a square channel (SQ1 or SQ2), you will change the Duty Cycle (possible values are 00, 01, 02 and 03), if you are in the Noise Channel (NOI) you could change the noise mode, possible values are 00 and 01. Keep in mind that you can change them too by using the Duty Cycle Macro of the instrument.
