Re: Gate randomizer circuit?

Wow, so many cool ideas! I really appreciate each and every contribution to this thread, thanks :tu:! Especially @kdjupdal: Yeah, I had briefly thought about noise into s&h as well. But didn't explore this further (thus not getting to the comparator part ;)) when I decided to order the MI Branches P...

Re: Populating and soldering pcbs

I'm not sure two small IC sockets will work the same as a large one. They have a small edge around them. Using two small ones could result in the edge obstructing full insertion of the IC. I would check that first. From personal experience (yes, I actually did do that once or twice - was out of DIL...

Also the Yusynth Random Gates is fun!
Thanks, that looks interesting, too :tu: . At first I thought it's probably similar to the MFOS one (which I already have as part of the Noise Cornucopia module), but the latter is truly random and doesn't have a clock in.

Re: Gate randomizer circuit?

there are a few ways this could be done with logic if you want. if the incoming gates clocked a shift register noise source, and then the output of the shift register was AND'd with the input, youd get a gate output with 50% probability. otherwise you could go with a clock generator with variable p...

Gate randomizer circuit?

Hi, I'm looking for a gate randomizer circuit. I don't mean 'random gates' here, as for instance included in the MFOS Noise Cornucopia, but rather a circuit that accepts a gate signal and randomly decides if it may pass or will be muted, preferably even with a "probability pot". Something like this:...

Re: Why is it fun to BUILD modular synthesizers?

Why is that? You learn a lot, the "I have built this myself!" feeling when it works is great, you have your own unique instrument that no one else has. I also built several guitars, btw ;).

instead of replacing the ones i put in, can i ADD another of the same value capacitor to it by just soldering it into the holes as well as the one that's already there.
Sure. Their capacities will simply add. So if you have 1 µF and want 2 µF, put in another 1 µF in parallel.

Re: Please tell me why lin/log response on VCAs is desirable!

Does it accept a gate/trigger and response differently to that? You usually wouldn't control it directly with a gate ot trigger but with a modulation source - for instance with an ADSR envelope, which is triggered by a gate signal, or by an LFO. There is an illustration (oscilloscope picture) on th...

Perhaps also check out this document:

I have translated the PCB layout into KiCad, and my first build of one is now ready for testing *fingers crossed*.
