splnkr

[jaseknighter]

splnkr is an amplitude and frequency tracking sampler/sequencer/effects processor with a set of 16 grid-controlled bandpass filters for monome norns.

v0.3.1 documentation ← click for a pdf!

twitch tv walkthrough #1 (sampling) ← on vimeo

twitch tv walkthrough #1 (sequencing) ← on vimeo

note: the two walkthroughs linked above were recorded with v0.1.0 and as of v0.2.0 the grid controls have changed slightly (i.e. there is a new live sampling selector added to the device type selectors (2nd row of the grid). the pdf document (linked above) has been updated with the new grid controls.

the script’s README on GitHub has additional documentation.

requirements

• norns
• 128 key grid (required for sequencing)
• midi-enabled synth (optional)
• crow (optional)
• just friends (optional)
• w/ (optional)

installation

in maiden:

refresh the community catalog, find splnkr and install it, or

run: ;install https://github.com/jaseknighter/splnkr

then restart to boot the new engine

latest version: v0.2.0 (live sampling)

roadmap

• fix bugs and usability issues
• enable sequencing for 64 key grids
• live sampling
• rotate sequences and sub-sequences
• new and improved features requested by the community (tbd)

credit and appreciation

• first and foremost, i’d like to thank SPIKE the Percussionist for the tremendous amount of testing, feedback, and encouragement he provided as i endeavored to get splnkr ready to publish
• this project was inspired by the lines discussion about Jan Jelinek’s album “Zwischen” initiated by Matt Lowery. it was out of my conversation with Matt and his encouragement that the basic conceptual framework for the script was formed.
• crossfading and audio routing code is based on the stonesoup script and excellent sampler tutorial by @infinitedigits
• additional heartfelt appreciation is due to:
  • @catfact
  • @markeats for Passerby
  • @tyleretters for Goldeneye, Dronecaster, and Arcologies
  • @dan_derks for Cheat Codes 2

Looks incredible. Can’t wait to dig into this, thanks for posting. Will make a great companion for the newest round of lockdowns.

[Justmat]

wowee, the demos are awesome! looking forward to jumping in

[moono]

brilliant! i’m blown away again - can’t wait to dig deeper …

[chorus7]

Can’t wait to try this out! Looks amazing

[mattlowery]

Hatts off to you @jaseknighter. This is really something else.

[SPIKE]

SO AWESOME!!
And so glad to see the release!

This script is so crazy…It’s been hard to keep the secret!

This one is a definite “read the manual” and lots of experimentation kind of noiz beast!

[Zeke_B]

This looks really awesome @jaseknighter and the videos look great! Really nice work!!

just noticed this in the docs:

audio routing

unlike most other norn’s scripts, the splnkr script changes how audio is internally routed. this was done so that softcut audio can be processed by SuperCollider which isn’t the case with the default routing configuration. three routing options are provided in the params menu:

• in+cut->eng: sends audio in and softcut audio to the supercollider engine
• in->eng: sends audio in to the supercollider engine
• cut->eng: sends audio in and softcut audio to the supercollider engine

that is INSANE
so i’m curious, first of all, is splnkr the only script to try this? (softcut into sc)

also
is there a typo in the description? otherwise what’s the difference between in+cut->eng and cut->eng??

[jaseknighter]

@glia, thanks for bringing this typo to my attention.

selecting cut->eng only reroutes softcut audio to the SuperCollider engine. with this setting selected, audio in audio isn’t rerouted. i’ll fix this in the docs.

the only other script i’m aware of that does this sort of rerouting is @infinitedigits stonesoup script mentioned above.

EDIT: the typo is now fixed in the GitHub readme and pdf instructions.

[glia]

pretty wild

thanks again for the script and all the documentation!
splnkr sounds so special

I can’t stop looking at the how the wood grain on the shield lines up with the table on the left side

[asymmetriccut]

Thanks for sharing! I’m trying to use my launchpad as grid with midigrid (I’ve placed the code on global.lua) but is not working, there is a way (or it will be) to use it, or for now it’s just for “real” grid?
Thank you!

[jaseknighter]

i’ll investigate and report back.

EDIT: @asymmetriccut, would you mind sharing the code you placed on global.lua? also, when you added the code and restarted the script, did you see any messages related to midigrid in the maiden message window?

[infinitedigits]

@jaseknighter this is so inventive, so clever and so beautiful sounding! I can’t wait to dig in with it and play. you’ve once again created a whole world of music design/manipulation to explore. (and those demo videos are so simultaneously enlightening and lovely sounding!)

[asymmetriccut]

Sure
Here the code that I’ve placed (lib/globals.lua):

local grid = include("midigrid/lib/mg_128")
local g = grid.connect()
--g = grid.connect()

Thanks for your help

I’ve got midigrid working with the standard edit, running two Launchpad mk1 minis.

I put the following line just before g = grid.connect() in the globals.lua file

local grid = util.file_exists(_path.code.."midigrid") and include "midigrid/lib/mg_128" or grid

The issue with your edit is that g needs to be a global value but you’ve made it a local value:

### SCRIPT ERROR: load fail

If you want to edit other scritps there is a list here of ones that work with midigrid midigrid | norns community

Thank u very much
No error and my launchpad mk2 is working, but I think I will need two of those!
I will try to figure out, how is is works.

Thanks again

[Ramlies]

This looks amazing. Can’t wait to try once I receive my Norns

[jaseknighter]

many, many thanks to everyone who has posted such kind words about the splnkr script. i hope you and everyone who plays with the script has a good experience with it. i’ll do my best to address any bugs and usability issues that appear.

@asymmetriccut

No error and my launchpad mk2 is working

i’m happy to hear you were able to get your launchpad working (thanks @edrapley for the assistance!), but i’m not sure how much use you will get out of it with just 64 keys. i will try to get the script working for 64 key grid devices sooner rather than later.

as a side note, if you edit your long post above, you’ll see an option to hide code under the settings icon in the top right corner of the edit menu. that way, folks won’t have to scroll through all the code when reading through this thread.
