MiniMax Oscillator 3

[MFF]

I just noticed something strange. The saw+triangle waveform (second choice from the left) sounds completely different on oscillator 3 than it does on oscillators 1 and 2. On oscillator 3, saw+triangle sounds just like saw (third from the left).

I never noticed this before because I usually use oscillator 3 as an LFO.

Can anyone else confirm this? I have the latest OS installed.

I just re-read the Sound on Sound review. Apparently this is intentional. It would have been nice if Creamware changed the front panel graphics accordingly:

"Creamware have varied one of oscillator 3's waveforms, replacing the mixed triangle/sawtooth with a reverse sawtooth (although this isn't shown on the front panel). The reverse sawtooth doesn't sound any different from the forward version, but it offers another, distinctive modulation source."

Yep, instead of the 'sharktooth' waveform Creamware used a reverse sawtooth for Osc 3 as you'll discovered. A reverse sawtooth (sometimes also called a 'ramp' waveform) sounds just like a sawtooth wave since both have the same harmonic structure (the overtones are actually 180 degrees out of phase in the ramp wave, but our ears can't hear the difference).

Combining a normal saw wave and a reversed sawwave leads to a result that pretty much sounds like width modulation of a pulse wave.
