Yes. Imagine the Osc Shape knob as a mixer. That's all it does. It blends between PCM <> Sawtooth <> Pulse waveshapes.

At an Osc Shape value of 0, you have 100% PCM waveform, and nothing else. You can choose the PCM waveform with the "WaveSel/PW" knob.

With an Osc Shape of 0 > 63 you are fading the PCM waveform out, and the sawtooth in. An Osc Shape value of 64 (middle) would be 100% sawtooth and nothing else.

From 64 > 127 you are fading the sawtooth out and the pulse waveform in. At 127 you will have 100% pulse and nothing else.

So an Osc Shape value of 32 (a quarter) for example would be blending 50% PCM wave with 50% sawtooth.

Or, an Osc Shape value of 95 (three quarters) you would be blending 50% sawtooth with 50% pulse.

[Incidently, you can never blend PCM with Pulse unless you bring a second oscillator into play.]

And, from 64 to 127, I'm dealing with a pulse wave and then the Wav Sel/PW knob now controls the pulse width?

Yes. In these instances, the "WaveSel/PW" knob determines the pulse width of the pulse waveform itself (before it's blended with the sawtooth).

So, getting back to the Oscillator Wave menu option, it "should" reflect whatever PCM wave I dialed in using the Wave Sel/PW knob "before" exceeding the value of 64, correct?

So, I'm guessing when they say that "the wave menu option is always available regardless of the shape setting", they're saying that I can change the oscillator using this menu option, thus overriding whatever setting I previously set using the shape knob?

If the Osc Shape knob is between 0 and 63, the WaveSel/PW will state the PCM waveform used for blending with the sawtooth.

You can change the PCM waveform using the WaveSel/PW knob at any time while the Osc Shape knob remains between 0-63.

However when the Osc Shape knob exceeds 64, the PCM waveform is no longer needed as it becomes inaudible... The Osc Shape knob starts to blend the pulse waveform with the sawtooth instead, so the WaveSel/PW knob switches to "pulse-width" mode to control the pulse element.

Let's start afresh. Ignore the sawtooth by setting Osc Shape to a value of 127. You will hear 100% pulse waveform and nothing else. Use the WaveSel/PW knob to directly control the pulse width of this pulse waveform...

... Now simply use the Osc Shape value to blend the sawtooth back in (if desired). If you don't want any sawtooth, keep Osc Shape at 127.

The WaveSel/PW knob will never affect the sawtooth waveform. The sawtooth is always static. The WaveSel/PW knob only affects the PCM wave, OR the pulse width of the pulse, depending on which range the Osc Shape value lies (0-63, or 64-127).

And the Osc Shape knob is nothing more than a mixer.
