Ring (and/or Balanced) Modulation for the modulator masses

[Strange Tales]

I'd build one of those but they're huge and that second PCB is soooooo cramped.

Maybe if I could throw one in it's own little box, not sure though. I just abhor any sort of wiring because I'm so bad at guestimating length and then having to make it clean.

Try the cfm thing and two passive ring mods. Perfect circuit sells the cfm boards for 5 and passive ring mod is not big deal (but modular addict sells cgs boards and synthrotek has PCBs too). Seriously, probably $30 or less if you don't use a panel and just test it on the breadboard or pizza box.

I really think it will get you close (and if not, you have two cheap ring mods and a wave rectifier...sounds good to me).

Four ring mods with folding...

Freaking nice. CG stuff is pretty cool too.

That eurorack in the video has at least 15 ring mods haha. I think all quadrant multipliers...seems eurorack likes that style.

[Chankgeez]

ha ha. nice.

… and all I was gonna post in this thread was this passive ring mod module I found for sale on Reverb for $50:

(Your post is way better. Too much talkin', not enough ring modulatin' though. )

I'm subscribed to DivKid's channel too. Must've missed that one.

(That video almost has 666 views as well. )

Still a lot of talking, but at least they keep the camera on the oscilloscope haha.

No real talk of ring mod in this one though....but 600 euro...dang...I guess instead it works as a folder x4, ring mod x4, vca x4 plus a mixer...eh, yea, I suppose.

Those xr22 fts have a ring mod and two frequency settings for the oscillator that can be clocked by its internal squarewave or any other signal +2v or higher...so it kinda makes a wave have two different sets of fundamentals with a blendable ring mod and two vcas (each can be controlled in amplitude by cv). Kind of a lot in there....envelope frequency keying?

That cg vca next to the cfm thing is a ring mod too with expontential or linear amplification of the waves as they go through the quadrant multipliers...little bit different.

Forgot to mention that watch! Yup, and rings.

That passive looks nice for the price. With the parts he used, that's slightly above what it cost in parts I assume. Not much to em.

Good one!

Planetoid II too! LFO and switchable square/triangle with hi/low footswitch.

[Chankgeez]

Yeah, that some of that eurorack stuff is still a little too pricey for me. Maybe someday.

whipped up this guy using a xor gate for multiplier and a gated vco for the carrier. will post clips tmrw. works pretty well. basically you square the input signal and feed it to the xor, but also have an envelope of the original source and use that to gate the carrier. the V into the vco is a voltage that changes the frequency of the carrier. then there is a clean/wet mixer at the end (boring)

NIce game soundtrack! Love those vector games.

Seems like the M.A.S.F. Swan Song has a square-ish carrier that ranges from about 200 hz to 1200 hz.

[Chankgeez]

Is there a tiny little bit of ring mod at the beginning of this?
