* midi: Recalculate (and rename) the note frequency table.Frank Gevaerts2017-01-06
| | | | | | | | | | | | gustable[] contained plain note frequencies in milliHertz, but was named and documented to appear like a table of magic numbers. The values also seemed to be slightly inaccurate (up to about 0.01Hz, so probably irrelevant). This changes the name to freqtable to make the purpose clearer, and uses slightly better values.

* plugin_midi: expand gustable[] to 128 entriesFrank Gevaerts2013-06-16
| | | | | | | | | | The code assumes that gustable[] has 128 entries, while it only had 120. Since the entries follow a simple pattern (they seem to be note frequencies, so each entry is the previous one multiplied by the 2^(1/12)), expanding the table is the simple fix.

* ----------------------------------------------------------------------Stepan Moskovchenko2006-05-01
| | | | | | | | | | | | Added Karl Kurbjun's sound output patch, cleaned up some output. Main file is now midiplay.c, midi2wav is still in there for anyone who wants it. Set sampling rate to 22k, and increased note decay time. Reduced number of concurrent active voices and made new notes replace used voices if none are available. This makes lag less apparent. I really hope this wont go red. (turns around and runs) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9858 a1c6a512-1295-4272-9138-f99709370657
