Modulation path 2
Use this menu to set up the internal source for a second modulation path. Set it up the same way
as for the first modulation path.
The soft tab shows the modulation path that Int is associated with — in this example, AM2. It
could also be FM2 or ΦM2.
From this menu you can:
• Specify the source’s frequency and waveshape
• Define the phase relationship of one path to another
• Set the resolution of the rotary control when defining the phase relationship.
Int Freq AM2:INT:FREQ page 4-53
FM2:INT:FREQ page 4-85
