[1] Early on Vötterle published contemporary composers like Hugo Distler, Ernst Pepping and Willy Burkhard.
[2] In September 1944 Vötterle was denounced by Herbert Gerigk at the Hauptamt Schrifttum in Amt Rosenberg for anthroposophical and denominational ties.
On 21 November 1947 a Spruchkammerverfahren [de] declared him exonerated and gave the following reasons in summary: "From all this it follows that the person concerned at the latest since 1935 has actively resisted National Socialism according to his strength out of his anti-National Socialist convictions.
He saw the "Stunde der Gesamtausgabe" coming at this time and, in cooperation with publicly funded institutes, gradually began publishing scholarly critical collected works of Christoph Willibald Gluck.
Vötterle was also active beyond the field of music, for example as one of the founders of the Berneuchen Movement and the Brüder Grimm-Museum Kassel [de].
He received numerous honours, including honorary doctorates from the universities of Kiel (musicology, 1953) and Leipzig (theology, also 1953).
