midi hangs on iaudio

[chaebi]

Hello

whenever I try to play a midi file with the midi viewer, it says that it has started with sequencing but I can't hear any sound.
I've tried many different midi files.
What do I have to do?

have you installed the midi patchset? I don't know how the plugin is supposed to behave if no patchset is found but you definitely need it to play midi files. See the wiki page for a download link.

yes, I installed it.
If there is no patchset in the .rockbox directory, the plugin says that it didn't found a patchset and returns an error.
