MIDI playback: multiple songs & volume control
nerdrunner:
I love the MIDI playback capabilities on my C250's, but I can't figure out how to make it go on to the next song after it has finished with the previous song.
Also, MIDI playback doesn't seem to respond to the volume control.
Thanks for any help.
Chronon:
You have to manually play a new song. Since it's a viewer it can't take advantage of the core playback engine. Presumably, someone could write playlist handling into the plugin.
I just loaded a MIDI on my F40 and found that Up/Down adjust volume while the volume buttons do not have an effect. It seems like a problem with the MidiPlay key map.
nls:
Neither of these features are implemented in the midi plugin.
Chronon:
I merged two identical threads and deleted duplicate post.
nerdrunner: Please don't post identical threads in multiple forums.
nls: Regarding volume control, that isn't my understanding. The wiki page for PluginMidiPlay indicates that some players do have volume adjustment. My F40 seems to behave in a manner consistent with the key map provided in the wiki page (Up/Down adjust volume while the Volume Up/Volume Down keys have no effect).
nerdrunner:
I'm still very impressed with the Rockbox MIDI playback engine -- I've tried a number of relatively complex MIDI's, and only the very most complex caused the Rockbox MIDI to glitch (buffer overrun or some such message).
I did some more experiments, and the problem with the volume control is that it maxes out at too low a level -- i.e., I couldn't hear the MIDI playing on the airplane even at the highest volume level, while if I cranked my mp3's to nearly the highest level, I could hear them.
Perhaps the MIDI player volume control needs to be able to go beyond 100% -- I've noticed that a number of software MIDI players on PC's can crank up the volume beyond 100%. Of course, these MIDI players can also globally override the speed, so one can multiply the song beats-per-minute by a fudge factor.
The problem with MIDI files is that for classical pieces, the piece is broken up into different movements, which are typically separate MIDI files. So if a long piece is broken up into 5-10 movements, it would be nice to play them all together without having to restart each one separately.
