Brilliant script! I wonder how I can control those granular parameters using 16n faders? I’ve seen some videos, but it seems my faders are not affecting any parameters.

Thanks for the help!

xmacex · 2023-06-05T11:46:54.940Z

Did you map MIDI coming from the 16n to the norns parameters @adigold1? Norns parameter system is incredibly versatile for many, many configurations¹, and needs a bit of setup from the user, ie. you and me. You can set it up how you like, see control + clock | monome/docs

¹ norns love love love

Spent the morning before work streaming some graintopia and jamming about, really love this script. Its like a perfect compositional companion and being able to find different zones and recall them with favorites is really perfect.

Some more graintopia:

ITOH, another small request: Filtering for each island?
Also would be possible “scanning” thru grains in each lands?: imagine you select just one or two grains, those are always the “top” layer grains. I mean that, for example" you select only one grain and with a parameter you cal scroll thru the 6 grains selecting wich one is active, hope you can undestand my explanation!
-Also, there is an easy way that I can change code so the input is reaching graintopia for recording but not passing thru the output?
Thanks @infinitedigits you are a genious!

just as i suspected: graintopia+hurdy gurdy is an excellent combination!

Yes! You can just change this line to:

snd = sndDry + sndWet;

(i.e. remove the “in”)

JosueArias:

Filtering for each island?

cool idea!! yeah this is something that could be added in the future. added to the list.

sounds extraordinary, love it. thanks for sharing.

love this performance! grid+piano is my favorite combination.

really excellent work, loved listening to this. very cinematic.

appa:

Love graintopia. Thanks

whoa love your video - fantastic textures and all the sounds fit so well together.

Ya-L:

’m not sure to understand what value needs to be changed to remove the reverse

to remove the reverse change this line to this:

var lfoForward=1;

then no more reversing!

sixolet:

it does some kind of time-based loading of files

softcut is the renderer, so I want to only load one file at a time in case they overlap in the buffer. so when you load a pset that has multiple files, the files are put into a queue to be loaded, with the timing controlled by how fast the softcut can load+render each one. this can very likely be causing a race condition. I don’t mind putting another params:bang() after loading if that solution works. if it works it works

UMCorps:

. Been lost for hours in washes of sound.

ah your sounds are easy to get lost in, thanks for sharing.

I think it started happening after trying connecto script and made a change in line 79 to var lfoForward=1; in graintopia in hopes to remove reverse audio, but I have no idea if that’s related.

Apologies for formatting fail

jaseknighter · 2023-06-26T05:59:54.784Z

@vantablack, you might try to undo the changes in (or remove and reinstall ) the script(s) the you updated to see if that resolves things for ya.

vantablack · 2023-06-26T16:32:27.303Z

I reinstalled and so its all good, i’d still prefer no reverse audio tho

jaseknighter · 2023-06-26T18:42:03.738Z

@infinitedigits may have a better way to do this, but I think I removed the reverse audio by updating the value of Drand on line 79 from [0,1],inf to [1,1],inf, like:

var lfoForward=Demand.kr(Impulse.kr(timescale/Rand(5,15)),0,Drand([1,1],inf));

robbie · 2023-06-26T20:26:48.720Z

That’s the exact same alteration I made to lock the direction; works happily here.

(As a simplified explainer in case anyone is interested, in the original code, Drand randomly returns a value of either 0 – the grain plays in reverse – or 1 – the grain plays forward. In the modified code, Drand now returns either 1 or 1, so the grain only ever plays forward.)

vantablack · 2023-06-27T11:04:18.034Z

I’ll make those changes in that line. Thank you

infinitedigits · 2023-06-28T12:56:59.238Z

thanks @jaseknighter for beating to the punch!

yep that line should work great for removing the reverse.

I’ll make a PR soon to just have an argument change that between 0 and 1 so that it is toggleable from the menu. thats a really easy change.

PeterBark · 2023-07-11T17:34:41.553Z

had a lot of fun with this one. Thanks again @infinitedigits for taking the time to chat, and answer my questions!

infinitedigits · 2023-07-11T18:07:17.532Z

wow @PeterBark !! your explanation is SO fantastic. way better than anything I’ve tried to explain. also you have some amazing sounds as per usual. thank you so much for creating this amazing resource

dandante · 2023-07-11T21:21:28.978Z

Thanks! I didn’t really grok how favorites worked before watching this. Also, didn’t realize everything you could do with tuning each land in the params menu.

I second this, if we choose to have just one grain then it would also be nice to select which one of the grains it is. Maybe this is where the grid can come in to play as a grain selector??

thanks Z

PeterBark · 2023-07-12T14:53:05.044Z

The favorites are so cool. I haven’t tried this yet, but if you record/load a file with multiple chords you can pretty much play the script like a granular sampler!

Agree with @JosueArias and @0netwo0netwo thatt would be so sweet. Another grid feature that could be nice would be selecting favorites. As it is right now if you’re playing back the last favorite and want to go to your first one you’d have to scroll through all of the ones in between. Being able to select a favorite to jump to would be really helpful!

Gatrix · 2023-07-24T10:51:31.080Z

Hey there, I have the problem that as soon as I load two “complicated” samples into graintopia, my norns cpu hits 100% and everything starts to sound bitcrushed, but in a bad way. Complicated in this case means heavily reverberated guitar signal with some other stuff going on as well. Normal guitar signals still work without a problem, but the cpu still hits 74% when I load 3 of them. It may be one of those problems only I have for some reason, but if there’s any way to improve graintopias performance, I’d be happy to hear it. If not, that’s okay too, I want to put my norns at the start of my effects chain in the future anyway.
