You write that you track signal to IC4. Do you mean that there is a voltage at pin 15 (D#5) as long as the key is pressed ? Normally, you should first measure the decreasing voltage corresponding to the velocity and soon after, the voltage of the aftertouch. Which means that if you press D#5 very slowly to produce a slow velocity and if you keep the key slightly pressed to hold the note on without producing aftertouch, the signal should go very fast to 0V. Is this what you get at pin 15? If so, also check pin 3 (out) under the same condition.
