How to add a Trigger to Audrey II Synth


video upload by Wirehead Instruments

"Simple hardware mod to add a trigger to the Synthux Academy Audrey II feedback synthesizer.

The trigger shorts the feedback control to maximum voltage (VCC), so the control is set to max while the button is pressed.

Enables a different expressive performance vs playing the feedback control itself.

Parts: 1 x normally open switch

Caveats: Modifier-beware! I am not responsible if you blow up your Audrey!! ☹️ in particular, the mod is crude and merely shorts the wiper to VCC.

If the feedback control is set to the minimum, this effextively shorts GROUND to VCC through the wiper resistance only (usually less than 50ohms).

in testing this makes a slight glitch in the sound, but is likely to be doing som damage to the Daisyseed, so olease be careful!!!"
