[seqfan] Re: Question: best format for playing sequences as "music"?

[Hugo Pfoertner]

Please leave the MIDI output of the OEIS music function unchanged. MIDI is
still a standard format for encoding music in a space-saving manner without
using time signals. The Midi files generated by the current version can
easily be imported and further processed using, for example, Mathematica or
the widely used program Audacity. For example, you can change the
instrument, which would no longer be possible with a waveform time signal.
The problem seems to be that the now somewhat ancient Quicktime player no
longer supports Midi, nor does VLC for Windows. However, the standard media
player works in Windows, and I was told that "GarageBand" produces perfect
playback on Mac. So it appears to be more of a local setup issue on Neil's
MAC.
