Reading the manual at this URL: https://www.elektron.se/wp-content/uploads/2018/01/Digitone-User-Manual_ENG.pdf
The three highlighted entries appear to be wrong by my empirical tests:
(all numbers decimal)
ALGO documented as 91
, actually responds to 90
Ratio C documented as 92
, actually responds to 91
Ratio A documented as 93
, actually responds to 92
Is that link the most up-to-date manual?
Thanks! Hope that helps.
