Keyboard control

hi all,
is it possible to control 3 or more patches via keyboard. Like press a and starts patch 1 press b and starts patch 2 fadino on 1.
Is there any example where to learn from. I don’t find so much documentation on how to use vvvv.

depends on you definition of ‘starting’.
if you just want to enable/disable a patch, no problemo, Keyboard (System Global) is your node.
if you really want to add/remove patches on the run, you’ll want to get deep with CreateNode (VVVV) or even SetPatch (VVVV) .
