Most bands ( pub bands )have intro music.. I also have a few song intros.
We play lots of different venues so getting the sound man to trigger is unpredictable.
At the moment I have to connect an mp3 player ( a phone) and trigger them myself, which works OK but I use up the effects loop ( doesn't bother me but seems like a bodge).
it would be great if I could store and play small MP3 files from my Kemper out through the main outs...if I could trigger from the remote...heaven!
Not a big issue, just a nice addition...
