The on the fly Erase feature is great! But the Yes/No is clunky during pattern record mode.
Borrowing a feature from many other drum machines could simplify this, if: In Pattern Record mode, a user could erase all of one instrument’s pattern by holding Erase while pressing the pad for the appropriate sound.
I like the idea of selecting which tracks to erase then committing. Undo would be cool. Or at least confirm you want to erase by a 2nd press on the Erase button, since your finger is already there. Then Back can still = No
You have (since the initial release) both options. Use the erase menu for safer mode with confirmation, or exactly as @mstrblstr described it, for fast and no confirmation.
@abstrktd undo is a totally new feature, coming eventually.
