[PD] A growing idea

Ho probs, glad to be of help.

Anyway, forgot to mention that the randomized array method I not implemented
in an obvious way in my  "error" patch and it has two drum sets. As a
result, it might be a bit confusing to look at. However, the new automated
RRADical drum machine patch I mentioned is much more clearer, but it might
take me a few days to clear it up and make sure its ok for release.

Anyway, my suggestion is that do play around with "error" but don't use that
as an example/template of any sort. It will be much easier and clearer if
you implement the randomized array method yourself. Otherwise wait for a few
days and I will be back with the RRADical drum machine patch;)
