Google not being too helpful on this, I need a voltage controlled filter circuit or ideas, nothing too complicated or fancy, it's my first analog synth project.
When a keyboard key is pressed, the control voltage needs to iniciate the bandpass filter to sweep upwards in frequency, slowly.
I got something working with a twin t filter and ldr but it's getting messy and it's not smooth.
