Midi manufacturers can’t seem to agree on mappings of note numbers, pretty daft considering Midi is supposed to be a standard, middle C (note #60) is C4 on Roland gear, but C3 on Yamaha gear for example, I think Elektron consider C5 to be note #60 IIRC. Some manufacturers use the Roland (IMHO correct*) mapping, whilst others use either C3 or C5.
*Given that Roland along with Sequential Circuits conceived midi.
Could the issue be related to this?
Edit - Seems that OT considers C4 to be note #60, but Digitone and Digitakt consider C5 to be note #60
Edit - @Open_Mike already mentioned Roland/Yamaha above, but left my post to document the Elektron disparity.
