for some explanation and mods for the WSG.

well there is definately a big difference between using an HCF40106 and a 74C14N, which is the stated equivalent to the CD40106 on the MFOS website. The 74C14N is a lot more 'gritty' sounding and runs a bit slower.

I think i prefer the sound of the HCF40106 but i'm not 100% sure

I've made some demos of my WSG using the HCF40106 and the 74C14N with the controls in exactly the same place. Each demo has the HCF40106 first and the 74C14N second.

Jeez, that is a pretty dramatic difference.

HCF is much nicer... but the other one is cool too.

Hiya all, tis my first post so first off.. great forum here, good attitude and all!
had to post because I love the WSG, I have built two of them from the vero layout by Unkle Krunkus (anyone used that?) it sounds great to me (I used a cd40106). The LM 741 is a single op amp, has anyone tried any others in its place? I haven't yet but will do when I get hold of some  . I just checked this new PCB from the MFOS site and it has extra switches!!  Is there much difference to the original WSG? I'm hoping I can add these extra switches to my vero build

fegg.

yeah, got my MFOS pcb, got to get parts ...
I think I have to build it twice one with HCF4106 and one with the 74C14
... a must have

I can't remember, does the original WSG have two voices?  Cause that'd be a big difference.

[catweazle]

Yop, has two voices mixed together

[fegg]

the original has mostly the same pots (only coarse "oddness" cutoff and no resonance) but minus all switches apart from "Wackiness"  ...I'll try and drop them in.

p.s. just realised my 2nd vero build had two resistors misplaced, but still made Noise
