[L2Ork-dev] Big patch takes forever to load

Fri Dec 6 20:35:01 UTC 2013

Hi there,

lately I've been in a kind of parking position with Pd but today I made
some experiments and it seems I got something. I tried to remake my "big
patch" from scratch, adding abstractions one by one, and the feeling I got
is that it's getting sluggish gradually. However, when I add [alpi_env]
that's the moment when CPU goes 100% and the whole thing gets stuck there.
alpi_env.pd is a slight modification of s-env.pd from an old version of
s-abstractions. Note that opening alpi_env.pd directly doesn't trigger the
problem, only embedding it in a parent patch. It used to work well until
the time tkpath was introduced, but of course I don't know if the problem
is related to tkpath or not.

Some other minor observations:
- when opening m32_mu100.pd, the vsliders update very slow when moved. This
is only with sliders that are routed to tabwrite (thru some other objects),
while an unconnected vslider updates lightning fast. And the symptom only
occurs when the m32_mu100.pd is opened, not when operated as GOP in the
parent patch.
- still in m32_mu100.pd, arrays are displayed as curves while they were
saved as "display as points" (and are displayed as points in pd-extended).

All the mentioned patches are still in the zip at

Thanks,

András
