There are two control sections: linear and exponential. The exponential section consists of the XTune control, the 1V/Oct input and the XFM input with attenuator XFM. The exponential CV is the sum of these three voltages. The linear section consists of the LFrq control and the LFM input with attenuator LFM. The linear CV is the sum of these two voltages. A bi-
Other waveforms like triangle, sawtooth, rectangle and sine are obtained from the TRASIN/TRACOS signals, all five waveforms are available as quadrature pairs (i.e. with 90 degrees phase shift).
