The Beauty of Mathematics Part 1 // Math in VCV Rack

[@UltraTroninator]

Nice vid! After going through the spreadsheet you missed the big punch line on inputting math to VCV Rack. If you're inputting a voltage and, say, want to go up a semitone in a 1 volt/octave input you can use "+1/12" in the text entry box. Or pick how many steps you want to go up or down and just have it do the math.

[@yourpalrob]

Dude!! You're so right. That is the slickest way to use the math input along with calculating pitches. Thank you for pointing that out! I totally missed it lol 😁

I call that a "cicada method" cause some sort of cicadas have either a 13 or 17 years development cycle, so their hatching time is possibly not overlapping.

[@yourpalrob]

I like that! Cicada's are cool. I think I'll start calling it that too 😁

[@kp8923]

Stealing this for sure

[@JamesBannon-fz6qo]

I’m curious. What calculator are you using? It’s not one I’ve seen before.

[@yourpalrob]

Hey James! Thank you for the question. It is the stock calculator that comes with the Kubuntu flavor of Linux 😁

[@JamesBannon-fz6qo]

@@yourpalrob Thanks. It’s been a while since I checked out a GNU / Linux distribution. Looks good.

[@koma2000music]

I didn't know you could input expressions in the text fields.. pretty cool! 👍 Can you think of any use for that?

[@yourpalrob]

I haven't messed with it much, BUT! If it can take variables, then it could be powerful. You could put like (VCO1 + 300) or something to the tube of that and it would play 300Hz higher than your first VCO. That might be cool!

[@burningpaper]

This is insanely helpful and clear. Thank you!

[@yourpalrob]

Thank you for the comment, @burningpaper I'm glad it was useful to you 😁

[@WailingRaven]

I can barely understand this, because I'm not one of _those_ Asians that has a calculator built inside of their heads. 🤣 Solid video as always, dude. It's quite interesting, seeing people do stuffs with those crazy microtonal stuffs.

[@yourpalrob]

Lol! Microtonal music is insane. I really enjoy it, but I have such a hard time making it. I'm much better at the "no wrong notes" mentality but I'm locked into 12EDO.

[@WailingRaven]

@@yourpalrob Hmm, I wonder how Jazz would sound like with 31EDO. 🤔 31EDO Giant Steps, the Dark Souls of Dark Souls of Jazz.

[@yourpalrob]

Haha, you would need a special instrument or the entire band playing trombones.

Type in note letter into osc tuning dial. Thats worth the price of admission! 🤜🤛

[@yourpalrob]

It's a great feature! It doesn't work on every oscillator, but all the ones I tried worked fine. 😁

[@CatFish107]

As someone who only ever uses spreadsheets when required by employment, and hasn't had a class on them since the 90s, thank you for the little tips, ie filling in the first 2 cells, and dragging down!

[@CatFish107]

Oooh, I wonder how open the functionality of inputting math on the pitch knob is? Can you input functions? Thinking some backdoor fm, possibly? Will it execute arbitrary code? Lol.

[@yourpalrob]

Lol! I haven't messed with it much, but if I had to guess I bet it is pretty open.

[@CatFish107]

Regarding primes for rhythm, that's a neat method I've not used. How I've used primes is via a clock divider. I have a master clock running at some rate equivalent to the fastest burst or drum fill I want, then divide that down to run sequencers / rhythm generators. I'll take, for instance, a /5 to the drums, and a /7 to the melodic sequencer. The pattern lengths aren't something I've fiddled with, but I sure will now.

[@yourpalrob]

Oh! That's a great technique! I'm going to use that lol.

[@CrusaderGeneral]

Awesome work as always bro

[@yourpalrob]

Yo CrusaderGeneral! Thanks dude. I appreciate it! 😁

[@paulhermansen6196]

Ok, but how do I do meth in vcv rack?

[@yourpalrob]

Haha! With so many free modules, there has to be one for that right?
