Howdy! What are you using to control the D? If you're using the MIDI in I can't tell you what's wrong, but the main thing that comes to mind is that you need to gate both the filter contour and the loudness contour for it to sound. As far as tuning is concerned, the knobs for osc 2 and 3 go 5 full tones away in either direction, so you may need to change the octave if you're still not able to match pitch. If that still doesn't work it may need some calibration and that's past my ability haha
Happy bleeping!
