Hmm, that is not the case on an up-to-date IDE: analog outs have "dac~ X" and digitals have "Pd digital: X". It seems indeed that it was the case in the past that analog outs would have the
adc~ label, but this issue got fixed on

adc~ in there. Do you have a very old Bela image? You should probably take advantage of the new functionalities of the new image , but you can also just decide to update the core code instead.
