[sharing] random impulse response using multiconvolve~ (via Rodrigo)

I've been checking out the HISSTools Impulse Response Toolbox
and found Rodrigo Costanzo's IR tutorial on YouTube. At one point there's a demonstration using Max logic and multiconvolve~ to generate random impulse responses with an exponential decay characteristic.
As an exercise I made a version of Rodrigo's fun patch. This version allows the user to generate and compare two impulse responses, vary the exponent and number of points, and use live input or audio file playback.
My next step will be dynamically extending the IR buffer size...
