7.2.8. Lin FM
Linear (Lin) FM will add harmonics to VCO 1 in a very different way than the exponential FM
provided by the FM knob in the VCO 1 section. One of the characteristics of Linear FM is that
it is less likely to disrupt the fundamental pitch than Exponential FM.
Here's an experiment that may help show the difference. First, reconstruct the basic
from the Quick Start chapter and then:
• Raise the level of Osc 2 in the OSC MIXER
• Set the VCO 2 Range to All and tune VCO 2 an octave higher than VCO 1
• Lower the level of Osc 2 to zero again so you will hear only VCO 1
• Hold a note and listen to the pitch of VCO 1
• Turn the VCO 1 FM knob gradually from zero to about the 4:00 position.
Result: After the FM knob passes the 12:00 point, the original pitch of VCO 1 becomes
increasingly difficult to detect. Try sweeping VCO 2 also and you will see that the
relationship between the two oscillators is frequently inharmonic. That is exponential FM.
Now let's set up a patch in the patch bay to illustrate the capabilities of Linear FM. Looking
only at the patch bay for a moment, make these connections:
• VCO 2 section: Pitch 2 Out to ATTENUATORS section: In 1
• ATTENUATORS section: Out 1 to VCO 1 section: Lin FM (In)
• FILTER section: Connect one end of a cable into the Cutoff input to break the pre-
wired Att 1 connection
The patch bay should look like this:
