My brother ordered a Trio+ plus from Amazon for me, arrived 3 days ago. First 2 days have no problem, till I followed the quick start guide 10 to erase the loop today, the LED armed with flashing red light, but the light won't stop blinking to learn when I teach it a chord progression. How do I get the Trio+ to learn a chord progression after erasing a loop? How do I properly reset to factory setting, would it solve the problem? How you turn the Trio+ on/off? Thank you very much for your assistance. User's recommendation: Fun toy to write songs on.
