yeah, with a DC coupled interface you can set up an lfo in your daw and send it to your modular for example

You can also use AC coupled with modular but only for clock/triggers.

I learnt the difference between the two after watching one of the Native Sessions Reaktot vids on YouTube- I think it might have been Chris Hetrick, the Euroreakt guy, linking Reaktor to a physical rig.
I'm not sure DC outs on interfaces are that common (though the NI one he was using had one)

I'm pretty sure all MOTU interfaces are DC coupled, even the cheaper ones like the Ultralite series.

So anyone have any experience with the iridium?

I'm in the process of selling off a lot of things that I've either grown out of or just didn't enjoy as much as I thought I would and that looks like it would be a "do literally everything" synth to get instead of picking up like 3-4 things both hardware and software wise to cover what it can do.

Mostly into it because it's a wavetable synth as well as a sampler since those are the two things I seem to gravitate towards.

Ok so I was able to hook up my new keyboard to my computer and I "legally downloaded" a copy of FL Studio. Now I understand how Blade Runner soundtrack is formed. I am become Vangelis.

This "synth" stuff is pretty cool!

I actually ordered this thing from amazon (it should arrive in a few days) because turning virtual knobs with a mouse is getting tedious. The organ draw bars on my Casio will not map to knobs in any midi interface :( But once I get this thing I should have lots of physical knobs and sliders to fiddle with!

That was a bit of hyperbole lol. Of course I have not explored 99.95% of the functionality of any of FL studio synths yet, I mostly just fiddled around and hit the "randomize" button on all of them a few times each. But I figured if I am going to do a deep dive into a synth I may as well learn the best most complex one, so I settled on euro rack simulator.

Also I really really like generative music. I stumbled onto a few videos of people making randomized music with synth patches and it feels like a more pure version of Fractmus.

Does anyone have any special techniques they use for harvesting randomness? It seems the main weakness of digital modular synths is the fact they are simulations and therefor deterministic. Where an analogue system can pick up randomness from the environment. I was thinking about using a radio maybe? Tuned between stations you can hear the static of the universe and that would make a good random input. I saw this video of a synth module that uses a Geiger Counter to make sounds from atomic decay and I was wondering if there was other sources I could be considering?

Cryptography requirements have motivated modern OS' to put a ton of effort into building entropy, feeding in values from a dozen different subsystems (time, free memory, user keyboard timings, mouse movements, and so on). This means any random number produced by calling that function is going to be relatively high quality. There's no guarantee your vsts are using that function call, but the option is certainly there. It's a big waste to try to come up with your own source of randomness because people much smarter than any of us have put years of effort in to it.

I guess if you enjoy the process of rigging Geiger counter to your computer go for it, hacking on computers is fun. But you're not gonna a perceptibly superior randomness.

Wouldn't some form of noise source (white, pink, etc) into an S+H do the trick? Or combining any two slow, complex sources?
I use the random lfo shape on my Microfreak, a decidedly digital synth, a lot and I can't say I have ever noticed any obvious 'repeats', especially once I have the speed on that modulated by another source such as the cycling envelope.

Same with Reaktor Blocks, the various chaos generators with the Euroreakt set especially are very unpredictable, despite being 100% software

Was it anything specific you wanted this randomisation for, notes or filter cutoff for example?

No not anything in particular. I guess what I meant was the popping of a geiger counter has a different "rhythm" than pure static if that makes any sense. So I was just curious if anyone knows about anything exotic like the gieger counter. Like for example I saw a few reverb modules that use a physical spring? Things that are physically impossible to simulate in a computer.

this is fair I'm sure the random number generator the computer spits out is random enough I would never notice the difference.

For those geiger type pops play with a burst and/or a ratchet module. And a euclidean generator to trigger them.

lunetta cmos noise makers were originally conceived around using environmental inputs to control them. a breadboard, a couple of basic oscillators and some photoresitors would be a good start. converting wind power/direction into control voltage could also be done. if you can code it's possible to turn all manner of data into sound data

So I've got a few guitar pedals that accept CV inputs to control parameters, and I was thinking it would be cool to hook up some kind of external LFO source to them. I started looking around for something guitar pedal-y but didn't find anything I liked. I did find a lot of really cool modular gear though, which sent me down a rabbit hole figuring out how to set up a small case whose sole purpose in life would be to produce an LFO for my pedals.

I haven't messed with modular gear before so I don't really know what I'm doing, and I'm a little confused about how to reconcile different input and output voltage ranges. Some of my pedals accept 0-5v, and some accept 0-3.3v. Some of the modules I'm looking at output 0-5, some do 0-8 or 0-10 and so on.

What's the best way to hook things together in this kind of situation? I feel like I'd need some kind of voltage mapper where you specify an input and output range, but I haven't found anything like that so maybe that's not a thing. Or maybe I don't know the right terminology.

Funny that this is the topic of discussion because I've just recently been playing around with a lot of randomization stuff in Bitwig, making long weird drones as a way to explore all of the automation options. Just a whole bunch of crap like this:



Each of the dice over to the left is a different RNG sending twitches to several different parameters of four different delay lines, so that they feed into each other and feed back on themselves to different amounts. It's really cool because it will go almost silent for a good twenty seconds and then come back with something that sounds like an ocean wave crashing or a symphony swell or somewhere in between. That bottom right automation module is a sidechain, which will slowly bring down the feedbacks if the whole schmear gets too loud for a long time.

Basically I just create a couple of channels like this, send random notes to them, and let it go crazy.

good news is that even with covid supply shortages the stuff in the video is maybe $30-40 in components. if you want to take all the fun out it, the circuits are also pretty easy to simulate in reaktor or probably cycling.

everyone should build one of these:
