Hi Nicolas,
Thanks for your answer. The problem is when I turn on the solo instruments, a high frecuency note (E note) came out of the speaker (very soft, but anoying) without touching any key. I did try adjusting some trimers inside but no luck.
By the way, I do not now excetly the model number It says "The piper" Autochord.
Nano.
