With both PICs PORTA.1 pins set as outputs and making them again outputs after each SOUND command just to be sure I tried the PortA.1-1uF ceramic capacitor-piezo-PortA.1 and PortA.1-10uF electrolytic capacitor-piezo-capacitor PortA. schemes.

With both schemes I got the regular beep, a slightly louder regular beep and if both LED banks were completely in-sync the beeping sped up by a what sounded like a factor of four. That was it.

Many thanks again,

Rubicon.
