The Yamaha AN1x Synthesizer mailing list

I get stuck on this periodically. My apologies. I can use VCO 2 to modulate the frequency of VCO 1 for 2 op fm synthesis. Normally with fm synthesis there is a carrier and a modulator and the volume of the modulator will change the tone.

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

Thanks
