Clear machine problem

Hi, I recently got the MD.
Unfortunately I deleted in the edit page the GND BD machine, I made the operation once more, the new message says “Undo Machine” but the slot is always empty and I do not have the BD GND. What can I do?
thx

If you deleted it from your kit, then you can add it back in.
But I think you are a little confused, there is not ‘GND-BD’ machine.
There’s GND-SN (sine), GND-NS (noise), and GND-IM (impulse)

You probably are looking for TRX, EFM, E12, or PI-BD

Yes, you are right there isn’t GND BD. Problem solved, I messed up with the slots…
thx again
