phevosSo "warning: prev-imag: multiply defined
warning: prev-real: multiply defined"
I think there might be a wrong use of tables in the patch , but i have already try it in my PC and it works fine.
This happens also when running the patch on my laptop, so it's a problem with the patch.
phevosSo "Underrun detected: 12 blocks dropped"
How often do you get this? Like once at the beginning or continuously? You are performing 2048-points FFTs, but Pd does not spread the load across multiple audio callbacks, which is a problem with small block sizes. Try increasing the blocksize on Bela to 128 an see if that helps.
