Hello John

> keyboardist, it lacks two very common controls: modulation and pitch

The A100CGK is built for very small dimensions. Thats the reason why it 
does not contain it. In the A-100 range there are already moduls like 
the joysticks or the theremins, which can replace this.

The elektronik itself supports wheels:
Quote from http://www.doepfer.de/MKE.htm:

"These units can be connected to MKE:
     * Standard keyboard manufactured by FATAR/Italy with 2, 3, 4 or 5 
octaves (keyboard types TP/7, TP/8 or TP/9, with velocity)
     * Pitch bend wheel (special spring-loaded rotary potentiometer)
     * Modulation wheel (special rotary potentiometer)
Remark: Because of technical reasons only the single modulation wheels 
of our accessories list can be used in combination with MKE but not the 
modulation wheel set !
     * Rotary or fader potentiometer for loudness/volume control (Midi CC#7)
     * After touch sensor or socket for sustain switch or another 
potentiometer for any Midi controller"

Either you connect the announced A-174-2 to it or you add some diy 
stuff: http://www.doepfer.de/zubeh_e.htm#modulation%20wheels
