Fractional Voltage Controlled Multi TAP Delay ADAU1466

I'm quite new to AD DSP and have recently acquired a 1701 evaluation board and a 1466 Evaluation board. I'm trying to use the Fractual Voltage Controlled Multi Tap Delay, but I can't get my head around the control input (samples, percentage?) and  the data format to be used? I can't find anythig in the documentation.

I'm using the SIGMA Studio 3.16 Beta Version of the program.

I'm trying to control the delay time of six taps with one ADC.

Ant help is much appreciated

    Thanks for the details how the delays work and the tip to use the debounce. Really helpful.

    I'm trying to emulate a certain 'old' effect unit (ADA STD-01) and getting pretty close. I want the delay time to be modulated by a slow sin wave (0.1 -10Hz) in which case the debounce doesn't work .  Caused by the modulation I get some distortion, so I guess I have to play around a bit more with the available modules. I chose the fractual tap delay module instead of the 'normal' tap delay as I thought it would do some sort of interpolation when changing the delay time and therefore does not produce the same amount of distortion? Anyway having fun playing with the ADAU1466 (and the 1701).

    Thanks
