[PD] Active/deactive gemheads

Sat Jan 12 20:46:48 CET 2008

Hi Donal,

in cases like this, it helps to learn a bit about dataflow in PD. All 
that you are really asking for is a logic check. Is it greater than 
this? Is it between this and this? Is it greater than that? Check the 
attached patch and make sure to read the help patch for the Relational 
Operators ([>], [<], [==], [!=], etc).

best,
d.
