Still no word on gop on and off via an object?
No GOP on/off sitch is available. If you hide your GOPs in a subpatch, they don't really affect performance anymore, so you might want to do that. However moving around lots of objects (GOP or not) will always be a critical operation in current Pd.
well, there is ...
|pd sandbox|
|;pd-sandbox donecanvasdialog 0 0 0( <- switches gop off
|;pd-sandbox donecanvasdialog 0 0 1( <- switches gop on
(it's a hack... don't expect that it's going to work if the subpatch is opened .... booom)
cheer ... tim
