Pitch settings

Addivox is a monosynth — it plays one note at a time.
Transpose shifts every played note by a fixed number of semitones. The keyboard display still highlights the incoming MIDI note, but the sounded pitch is shifted by the transpose amount. This control is not patch-tied and keeps its value when you switch patches.
Tuning applies a global pitch offset in cents (hundredths of a semitone) to all harmonics. Like transpose, this is not patch-tied.
Portamento controls smooth pitch glides between notes. Min and Max set the glide time range. In Settings, Portamento CC selects CC 5 (continuous min–max) or CC 65 (binary min or max).
