Matrix Modulation AUX connection not reflecting in knob's lastModValue

[ustk]

@Christoph-Hart When using an AUX connection, like in this case LFO 2 over LFO 1, both the target and the plotter are behaving fine, but this is not reflected back in the knob's lastModValue, which continues moving as per LFO 1 value.

Might be intentional though...
