Yes. But unfortunately it also has some influence to the frequency in LFO
mode (i.e. when you change the shapes also the frequency changes). In slew
or envelope mode that's not a real problem, but it's not possible to change
only the shape of the LFO without changing the frequency a bit.

Also the V/Oct input is not really V/Oct. We will change the label on the
front panel probably to "exp.CV".
