filtergraph~/biquad~ and tapin~ tapout~ are quick and easy. Use pattr/mtr/line on the filtergraph~ for automated wah and other effects; feed the tapout~ back into tapin~ for delay feedback.

You said you worked with pitch, so gizmo~ ? Great possibilities there. If you take your float value to sig~ and run it through [!/ 1.] (i.e., take the reciprocal) and then to gizmo~, you can change the overall speed and the pitch will adjust to stay the same (eliminating chipmunks or the opposite). Of course, there’s a limit to how far this can go before you start to notice artifacts, but I’ve found a good range there.

I’m assuming you’re using groove~ and the waveform~ object. Note that you can pattr/mtr/etc. the looppoint values as well as the display values. So you could select various parts of a specific wave, then save what you did (mtr) and play it back. Even the "zoom" can be played back, which looks really cool…
