I could probably add a message to get it to play automatically. If you bang the [midifile] after opening the file, the right outlet will emit ticks_per_quarternote and microsec_per_quarternote messages. So the millisecond rate for the [metro] would be = (microsec_per_quarternote/ticks_per_quarternote)/1000 See attached patch.

Re: [PD] MIDIFILE read Tempo
That works great ! Even tempo changes within the file are updated. Thank you very much.

Hello, ist there any way to read the tempo information contained in a midi file? Or do I really have to set up a metro for mrpeach/midifile everytime ? Thanks for any advice, Maciej ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
