It's a feature, not a bug. To get a full sawtooth from the SAW output, the SHAPE pot has to be at 0 or 10. Either of these positions results in a 10V p-p signal. At 5 on the SHAPE dial you get a 0 to +5V triangle from the SAW out. That is useful. No other MOTM LFO produces a 0 to +5V triangle wave. In between on the SHAPE pot gives you in-between shapes. I have found that I use the SINE, TRI, and PULSE outputs of LFO's much more than the SAW outputs, anyway. I suggest that if you want a constant 10V p-p SAW, you can use a MOTM-300 or 310 as an LFO.
