Recommend an app that can randomly change AUV3 parameters
Hi,
I want to be able to randomly (but with some control) various AUV3 app parameters in AUM. For example I want to be able to change the octave knob in DRC randomly every say 3-10 seconds. What apps can do this and is it easy to wire up?
Thanks
Comments
You could use Rozeta LFO or MIDI LFOs with Sample & Hold waveforms running at a slow speed. It's just a matter of mapping the right CC's from each LFO to the AUv3 parameters for each app in AUM.
Ape Matrix has that functionality built-in.
In Drambo you can turn any modulation signal into a CC. There is a random number generator module that sends a new number (value) every time it receives a gate. You can enter the scale amount in the RNG too, so you can limit the range of its output. You can either place a trig on the sequencer to generate a new random value (every 2 bars for example). Or you could trigger the new value with an unsynced square or s&h lfo, if you want the randomization to be off the grid.
Module Routing: gate>RNG>CC Generator> Midi output
But like Wim said, a slow s&h lfo would also do the trick.
Thanks.
Want to use AUM not another host. And have Rozeta and it works, cool. Is there anything else that would give me more control over the randomness? I know that sounds odd. ;-)
If you want more control over randomness, you could take my RNG example, but put a Bernoulli gate before the RNG. The Bernoulli gate is just controlling probability. So you could have a probability of 10% that a new value will be generated (for every x triggers). Or you could set the probability that a new value is generated for every trigger.
A simpler method for controlled randomness would be to take the probability of the gate sequencer, and then draw in the precise values you want. Sample the velocity (the vertical bars) from the sequencer at the same time as a gate is let through the Bernoulli gate. Now you have control over all potential levels for your controlled parameter, and the probability of them triggering.
Don’t use drambo (at least not yet !). ;-)
If you ever decide to use it, feel free to ask and I can make the patches for you
I'd use miRack: incredible amount of modules for controlling your randomness, and you just need to wire them to the MIDI CC Out module and voilà, you'll get random CC values.
Looks very complicated! But interesting, nevertheless
Hmm. Seems like I might need to take the plunge on Drambo or mirack at some point
Depends on how wild you want to go. Check out the threads on holon.ist that generates CCs which can be piped through mirack to give you an amazing array of siganls, taken from anything from the Sun’s elavation, your GPS or even your heartbeat. Just type in Audiobus forum sear h box or Youtube’s search box for Holon.ist.
It can look overwhelming but it’s quite simple: I use one module to produce random values controlled by rate, offset and scale and then connect them, for instance here to modulate the x value of pure piano.
Yeah, apeMatrix is all about this.
MidiLFO can do it quick and easy
Interesting, a nice simple solution might be best for me here. Does that change randomly over time? Could you post a video?
Also could midiLFO be passed into midiGATEs?
Is there an app that shows cc numbers when you touch a parameter? Make it easier to assign cc numbers to Lfo’s etc
I thought MIDISpy would do it but can only seem to get note data
Most apps don't output CC, only receive them. Furthermore, most apps don't have default midi assignments. Which makes it problematic to make and share controller setups for specific apps.
Mozaic has a midi cc randomizer script.
A lot of roads seem to lead to Mozaic😜
@Poppadocrock this one ?
https://patchstorage.com/midi-cc-randomizer-and-scenes/
Is there one that changes over time
Dead simple script in Mozaic. Could also use StreamByter.
Check out this Wiki page: https://wiki.audiob.us/doku.php?id=mozaic_scripts_list starting with the section 'CC Scripts'.
There are many different functionalities available. It's possible you might find something that solves what you are after.
Mozaic always saves the day
Great info here! Thanks all!
No. midiGATES only works on notes, note CC's.
I see no reason why Mozaic is needed here.
An S&H (Sample and Hold) LFO in Rozeta or midiLFOs outputs randomly changing midi CC's over time. This is exactly what you need. You just need to map the CC that it outputs to the parameter you want to automate and it will change to random values over time. Simple.
This doesn't need to be complicated.
It’s iOS; it’ll be complicated one way or another.
This.
If you want more random in your random, you can assign additional LFOs to control the parameters is this one. MIDILFOS has some of that jazz built-in (no additional AUM routing needed). Check the sliders to the right of the waveform. You can go deeper if you do the routing manually.
@lukesleepwalker I don't see this as any more complicated on iOS than it would be on desktop. Either way a random source such as an S&H LFO would have to be midi mapped to a synth parameter. It's not any easier to do this on any desktop DAW I've used than it is on iOS, but admittedly the range of desktop DAWs I've used is limited.
Another vote for miRack. Lots of options. Triggered envelopes, LFO, s&h, go nuts.
