I am on a Raspberry Pi 3 and I have Pd .46 .2 . I admit the patch I am working on is sort of a monster patch with a few big abstractions. But in the Audio Settings I increased the block size to 2048 and I set the Delay to 100 msec. That eased things up and everything was working fine.
However a few objects weren't loading properly when I launched my patch including tanh~ so I added -lib zexy as a startup flag. After I did this the CPU load got really high, it fluctuates between 75 and 99, and the audio is really glitchy. A lot of the time my midi controller gets somehow disconnected and I can't even stop or turn down the volume.
How can I lower the CPU load for Pure Data? Or increase the processing power for Pure Data from the computer? Are there any settings I can try or settings I should do?
