Request: Detune knob in delays

In the delays, I am really missing a possibility to detune the wet signal by +/- 1 - 20 pct. Doing so creates such a lovely psychedelic vibe that I frequently I use in my sound.

I can partly work around the problem by splitting the signal, applying all-wet delay on one branch, and detuning the wet delay signal. However, I cannot route this signal back to the input of the delay and thus create the “sliding pitch” effect.

So yeah, pretty please, with sugar on top :-).
