Hi folks,
Anyone else notice that the pure sawtooth wave offered by MPS is a little weird?
I compared it to the SAW in Serum, Massive and Zebra and those 3 all produce an identical SAW.
The SAW in MPS is a little different. If you check it on an oscilloscope is doesn't seem to be a pure saw. And more importantly it sounds different.
Anyone else notice this?
Not trying to be a nit-picker but a good, pure SAW is fundamental to synthesis!
Sawtooth in MPowerSynth?

Go to the advanced setting and turn off the DC filter. Saw waves will most likely sound different in some synths depending on how the are made. MPS generates its basic waveforms mathematically I believe. Turning off the DC filter will give it the typical saw tooth shape. Also keep in mind that analog synths don't even have perfect sawtooth shapes. Also some synths like massive might look perfect, but can sound off because of aliasing.

This actually came up before about a year or 2 ago, you can read about it in the thread below, but basically the fix is to just turn the DC filter off.

Thanks!
But what i don't understand is, why does the DC filter affect the tone of a saw so much?
Try playing a pure saw on C1. You'll hear that with the DC filter engaged, the saw gets a lot fatter sounding. At higher notes, like C3, the affect is also there, but less obvious.
Sorry for nit-picking but i'm a bit of a freak for these kind of details! And i wanna LEARN!
Strange thing is, the different isn't really visible on an analyzer. It's almost like the harmonic relations are being subtly altered to create that extra, perceived fatness.

I’m not 100% sure but I beleive the DC filter is cutting the low end which is subtly altering the phase. I imagine the difference in tone is due to the phase shift on the first harmonic/fundamental. That’s just my guess however.

The dc filter is (basically) a high pass minimal phase filter, you can test out how it effects the sound by using Mutility, it has the same DC filter but with several settings. Using it will change the sound a little, but notably if you use any kind of distortion or similar after.
