Subject	[Csnd] midifile output wrong tempo
	Hi When creating a midi file with Csound, the output file seems to have the wrong tempo. Also, I can play the file in windows media player (silly internal midi GM), but it seems the file is not readable by Cubase or Ableton Live. I can look at the file contents with midi2mtx and it looks fine to me, but obviously it is not as it can't be used properly by other software Do we need to touch up the midi output formatting? The example below produce a few notes, both in realtime to the midi out port and simultaneously writing to file. The midi file will play back in a faster tempo than csound generated the events, and the file can not be imported into Cubase or Live (even MidiOx won't play it, but windows media player will) -odac1 -Q0 -b2048 -B4096 --midioutfile=test.mid sr = 44100 ksmps = 256 nchnls = 2 0dbfs = 1 instr 1 noteondur2 1, p4, 90, 0.7 endin i1 0 1 60 i1 ^+1 . 62 i1 ^+1 . 64 i1 ^+1 . 65 i1 ^+1 . 67 e

	Ok; the first part of the bug was easy and it's fixed now. MIDI output files are now been written to play at the correct tempo. Second part will require a bit more research. I realised the MIDI file produced by csound is a mess when imported by Sibelius, so that confirms the trouble.
