Hi all;


I need some sort of audio controller that has at least 10 and ideally 20-30 buttons on it that can be pushed to start playback of an individually specified audio file. If I push the button again the file should pause playing. The device should be able to plug into a speaker port (it can also output into a microphone port--both will work). That's all that's needed. I'm sure the audiophiles in the room know what I need but I haven't a clue.


What devices can do this? I am also open to software programs that can work on a tablet computer for this task.


Thanks
