Hello all. A few years ago i foud out that by cutting diode D1 on the synth board (upper left corner) you can mix the sawtooth and pulse signals. the diode cuts off the width of the pulse to zero when the vco is in sawtooth mode. Removing the diode leaves the width intact so the two signals are mixed. be careful! note that from then on, all previous memorized sounds sound different than before because the pulse width in memory is not supressed anymore.
