Ted,
Thanks so much for your response... and I should have just said “drums” in my original question. With my first Casio (I think it was the wk-6500?), I could record drums onto Track One (along with a piano tone that I wouldn‘t need later), then record other instruments on the other tracks. Next, I would mute that first track, and record the other tracks one by one into my computer (for editing with the Audacity audio-editing program), and the drums wouldn’t be there… because they were only on Track One. But with the wk-220, the drums are on all the tracks.
When you mentioned the Start/Stop button for the rhythm (or drums), I remembered I could start recording by just playing the song. I would have to use the Metronome now to play in tempo, but the Metronome won’t be on the recorded tracks, so… Problem Solved!!
In the past, it was more “enjoyable” for me to practice, and then record, those other tracks while playing along with one of the drum-rhythms. Now I’ll have to play along with the just the Metronome, but I can do that. I’m just glad that my problem is solved, and I thank you again for sharing your knowledge and time, and pointing me in the right direction!
Steve
