I'm home. I turned on the AN1x. Here's what I found out:


With the synth set at fm only.


1. I can use VCO 2 to modulate the frequency of VCO 1 for 2 op fm synthesis.


Yes. The manual says this is not two op fm but it is.


2. Normally with fm synthesis there is a carrier and a modulator and the volume of the modulator will change the tone.


Changing the volume of the modulator will change the tone, but it's subtle.


3. So is the fm amount knob more for vibrato, and the fm source 2 more for fm synthesis?


With the fm amount knob set to 0 you get no fm.

Using VCO 2 as the fm modulato and changing the tuning of VCO2 gets wild results. Changing the edge of VCO 1 and 2 gets interesting results. Pitch envelope also. Won't be in tune, but sounds awesome.

I still like to use the sync +fm slave. The master provides the tuning--the synth will be in tune. The fm will cause wild and weird harmonics on the slave wave. A nice digital sound I can only get on the AN1X.
