Hi Larry;
That is one of the drawbacks of the expansion boards. If the person you send the song to does not have the board in their unit , the sound is distorted.
I have 3 boards some which have excellent sounds. I love the "Solo Soprano" in the last board but if I want the songs I recorded
using it to send to my friends . I make a CD of the songs and send it to them.
No problem for I enjoy making CDs.
Alex
