MFOS Noise Toaster

Post by zackH » Thu Jun 01, 2017 1:44 pm

Hey all,

I've been messing with a friend's NT and I breadboarded the interface and have had good results with everything but the filter cutoff... It seems as though the cutoff only goes from about 500 Hz up to about 7k or so, and only changes during the last half of the knob turn... Is this normal? I was expecting a wider filter sweep. Everything else seems to be ok. I also have already checked the component values around the filter section of the schematic and the component values seem correct.

Thanks in advance for the feedback!

It might be fine (or at least the way it's supposed to be).

First, mine has very little filter cutoff "action" below about 10 oclock, and none below 9 oclock. Things start taking off by 11 oclock.

But if you add a modulator, it gets useful to be able to dial down most of the way. Works fine on mine; give it a try on yours.

I'd double check the pot. Perhaps you used a logarithmic one where it should be a linear one?

From my personal experience (not with the Noise Toaster, but with the Sound Lab Mini and Sound Lab Ultimate & Expander synths, that's three VCFs in total), the cutoff works nicely and smoothly as you'd expect.
... why buy it for $100 when you can build it yourself for $150?
