Have we posted this Ringtone'd thingee here yet?

Was just listening to his live album w/ Thos. Morgan.... Kinda sad how few fx are on dat jawn

Lurve quadrature, and that is a great sounding implementation I'm in the have-it-all ringmod voting bloc. Some things are more actualizable in digi, and that's ok with me.

Later: this is making a great workdrone on "infinite" repeat

After thinking about it for a couple days, I might try an analog implementation over the weekend. I previously thought that I'd need four parallel analog ringmod circuits controlled digitally to do what I want it to do, because currently I digitally branch-out and ringmod four times the signal and sum it before turning it analog again. But maybe I can get away with summing the four carrier oscillators and doing the ringmod only once instead, via analog multiplication.

I have an ad633 and tc1044 lying around so maybe I'll try it. That charge pump isn't the greatest but it's only a proof of concept. If it works I'll order some lt1054s.

Yeah 1044s just need a regulator to make sure they don't get over 9v supply from my limited experience. I'm excited to hear it dude, love some analog circuits.

Win win Excited to hear what transpires

There's a few Ringworms on reverb.. always wanted one of those pedals

Well the analog implementation is working fine and dandy! Different sound characteristic, but equally fine. And importantly massive headroom. Running it on +15/-15.

Also added quadrature phase shift control. By default quadrature works by modulating each osc from the value every 90 degrees of the LFO, but I added a control that lets me shift it between 0 and 180 degrees for the 4 oscs. With 90 being the center position for the knob. Less than 90 and I get bursty sounds. More than 90 and the last osc starts overlapping the first's 'timing', which is really cool. Got some neat 3/4 gong beat going, with the first gong being a double frequency.

I normally hate working with 'high' voltage. I inadvertently shielded my eyes and backed away a little when plugged in the breadboarded 30v range charge pump for the first time.

That's pretty frickin' awesome....

All praises be to Lord Analog!

Are you getting your 30 volt swing from a transformer? Or the 1044 ?

lt1054, which just arrived yesterday.

the headroom on the ad633 is nicer than I thought! I thought I'd have to add a noise gate but it's pretty quiet when I let the ringmod trail off and palm the strings. no carrier bleed even. I imagine it'll be even better when its off the breadboard and onto a properly ground-fill'ed pcb and in a box. I bought this chip probably 12 years ago and never did anything with it. glad to see it works and isn't a fake.

it's darker than the digital implementation I had earlier (in the video), but thats not a bad thing.

[Chankgeez]

That is not a bad thing.
