This module is made to generate CVs which are accurate enough to keep pitch/transposes etc. completely in tune. This could be for 1V/Octave synthesisers, (doesn't have to be the AE modular). This accuracy applies to Oscillators and Sequence modules so could be useful for many purposes.
If the transposition buttons are not necessary and you could use two precision adders, take a look at the 2CVADD-HQ module
