I have an ESQ-1, which `seems` to have a flaw. I am trying to figure out how the AM function for Osc 1 and 2 actually works. I know what AM is, but it doesn`t appear to function as the manual says it does, The manual states that when the AM function is turned on DCA2 is switched off and is controlled by DCA1. According to the block diagram on the keyboard OSC1 goes thru DCA2 in this mode, confusing or what!. No playing about with DCA1 or DCA2 does anything. The only thing that affects OSC2 is a pitch envelope on OSC1. Not quite the way things should be.
Am I having a complete brain freeze on this and misunderstanding the way this function operates, or, is it possible there is a flaw in V3 of the operating system software.
Any keyboard/synth not covered by a dedicated section.
