I've been putting some songs together using mrpeach [midifile] and I calculate the metro playback speed using the tempo & time signature (as per an example by Martin on the last ~6 months ago). I noticed that on Pd-Extended 0.43 the playback is off, around 10-20 bpm too slow. The same patch & midifile on Pd-Vanilla 0.45-4 plays back at the correct speed. This on the same system with the same audio settings, using the same compiled [midifile] external from the Pd-extended app bundle.

Just letting y'all know in case you've run into a similar situation. Out of curiosity, what changed in PD 0.45-4 that fixes this? Soemthing with the metro timing? I must admit I went through the diffs when I updated the libpd core but I don't remember where that might have been ...

in any case, I'm glad to see my workflow is saved as playback now works correctly again, with the target being a libpd app using 0.45-4.
