I'm trying to set up a midi controller using pure data, which has worked so far, but for some reason its started crashing on a rather complex subpatch (the bangs freeze on 'on' position and the patch does not receive midi input) it also has the error message 'could not open midi input 0 (BCR2000 Port 1): PortMidi: `Bad pointer'

Any thoughts?

midi bandwidth limit?
