[PD] fftease 3.0 compatibility with Linux. Was Re: fftease compatibility with Pd-0.46-7

[Samuel Burt]

Ivica,

I downloaded pd-l2ork-arm6l-20151102. Is this the latest?

First off, "WhAaA- curvy patch cords!" The esthetics of l2ork are great. I
hadn't gotten around to checking it out, yet. The windows are a bit slow to
load, but I guess it is a compromise based on what system you are using.
(I'm using pd-l2ork through ssh -X from my pi2.)

After one segmentation fault, I closed it and reopened it and tried just
the pvoc~ help file. After that worked, I added it into my patch. The good
news is it doesn't crash, now. However, the audio is stuttering a lot. So,
I changed the processing delay from 50ms to 100 and the clicks slowed down.
I have it at 200ms and it clicks about four times per second. Deleting some
of two out of three of the pvoc~s helps, too, but maybe [pvoc~] is too much
for the poor little pi.

Even the [pvoc~] help file clicks about 7 times per second.. At least I'm
at a point where the object loads. I'll work at optimizing
efficiency/quality with the analysis window size.

Thanks for your help.

Sam
