Of course I'd like you to care about dparams, but I'm all for passing
control data through pads and using midi to store control data. dparams
can use any work that you do at a later date.

You might care more about dparams if:
- you wanted your control parameters to change at a higher rate than
your buffer rate (think zipper noise and
- you wanted a better way to store and represent control data than midi
- I got off my arse and wrote a linear interpolation time-aware dparam
so that i could really demonstrate what they're good for. (not likely in
the short term)
