SSIA. I actually didn't even realize it didn't have one until yesterday when I needed one.

You can already do this pretty easily by:

1. Make an Audio Rack containing a single instance of EQ8
2. Make one of the EQ8 control points a hi-pass filter and another a lowpass (so together, they act as a bandpass).
3. Map the frequencies of both control points to a single Macro knob in the Audio Rack, so that the Macro knob sweeps both frequencies in tandem.

http://blog.loopmasters.com/tutorials/d ... y-ableton/ goes into more detail about setting up the rack macros.

^^^Sure, but I think it's a pretty standard function that would be easy to include, and less cumbersome than using a rack.
