MCO seems pretty dirty - is this correct?

Put MCO from ALM busy circuits up for a quick tire kicking. I’m getting a lot of aliasing.

There’s no manual, but the page for the hardware original says " Expect an early 90s slightly crunchy digital type sound (ala Ensoniq, Kawai KX synths) rather than something striving for perfect analog emulation." So I’m guessing the aliasing is intentional and there isn’t a way to get rid of it?

Woop woop, that’s the sound of the beast Woop woop, that’s the sound of the ALIAS POLICE :rofl:

Seriously, I appreciate your work on this but haven’t got that collection so I can’t really comment.

In other news, I discovered that applying feedback to Booty Shifter makes a surprisingly good uni-vibe effect!


(not to hijack this, but why is MCO’s default frequency a B at 247.50hz and whatever I type in there gets multiplied by 1.5?)

You must set the little black Freq knob to zero. (but it still resets to E 165Hz after that and not C4)

But entering/typing C4 gives you a C4

Ah, thanks! that was easy :smiley:

I think it’s intentional and meant to be faithful to the hardware (both the devices it’s inspired by and the physical Eurorack module)

From the manual:

Expect aliasing at higher frequencies (top 3-4 octaves)

And from the Perfect Circuit marketing copy:

It specializes in gritty, aliasing oscillations which can easily be warped and manipulated
