Bug in fluid_synth_sysex_midi_tuning

[derselbst]

Hi,

There is a bug in fluid_synth_sysex_midi_tuning (src/synth/fluid_synth.c). The message length check at line 1369 should be

len != data[6] * 4 + 7

(rather than len != data[5] * 4 + 7)

The code is probably copy-pasted from MIDI_SYSEX_TUNING_NOTE_TUNE at line 1361, but since the MIDI_SYSEX_TUNING_NOTE_TUNE_BANK has the bank number BEFORE the key count, the key count is stored in data[6] rather than data[5].

Regards,
Erik Ronström
