Ok, I've tried everything and searched the forum. No Luck.

When editing patterns, I am trying to change just the Bass line by going to Edit Pattern/Record.

Changing from Play to Record, I start the synth and play my new Bass line.

When playing back the pattern, I can hear my new bass line, but the original bass line is still there!

The manual says that recording a new track erases the original track, but on mine it refuses to be replaced.

Any ideas please?
