Hello, first of all i want to apologize for my english and for writing directly to you, but i log in in this page and i don't know why i can't commenton forums. I have a boss br 800, and i saw that you know about this multitrack. I've been using my boss for about 2 years and recently i had a problem. When i connect my boss to the pc via usb, to export the tracks using the wave converter, i don't know why but the songs that i record dissapear from the boss. And sometimes when i open the wave converter it says "no card". I thought it was the usb connection but then i inserted the sd card on my pc, and the wave converter says the same. When i put the sd card back on the boss, the song that i record disappear...could be the sd card damage? It is the first time thatthis happens to me. But i need to export the tracks to my pc. My boss is 1.12 version, and i have windows 7. It happens the same in windows 10. Thanks
