Currently there are too many "clicks" to get rid of an unwanted loop just recorded and record a new one:
Maybe add a RE-RECORD button next to the red OVERDUB button ? Also the red circle to me indicates just a "record" function - so maybe a different icon for overdub would be better.
As before - think theres a lot of scope for improvement in reducing the number of "clicks" required to do the following on a selected loop:
* adjust volume pan
* switch to overdub
Unless i'm missing some shortcut somewhere.
