Abacus

added a tutorial (up top) because the controls are a little funky. open to ideas on streamlining it.

@xmacex of course amen break lol the waveform visualization basically came from seeing the db-force vst for the amen break and thinking can norns do that??

@fourhoarder same, had a bunch of 2-4 minute tapes that i wanted to splice up.

Ohhhhhhhh nelly. Add crow support for triggering and sweeping the buffer and you’ve replicated 90% of my ER-301 usage. This is so good!

infinitedigits · 2020-11-07T17:37:46.165Z

introduced a small update (v0.1.2) to make things a little more responsive.

@mattymattmatt can you explain this a little more? i don’t do any modular and crow itself is still mysterious to me. do you mean to listen to the two crow inputs and set the play position based on one of the crow voltages (“sweeping the buffer”?) as well as starting/stopping playing based on the other crow voltage changes? i’m really happy to try implementing it just need more of an idea what i’m doing

That sample…is that you, Lubomyr Melnyk?

hghrlearning · 2020-11-07T21:00:44.878Z

i love this. quick idea to help with sample cutting… maybe holding k3 in sample mode could loop?

infinitedigits · 2020-11-07T23:31:59.479Z

@hghrlearning done. its in updated v0.1.3.

@Cloud i didn’t know Lubomyr Melnyk but I do now, thanks for sharing that. the sample is actually me playing around with philip glass etude 17.

I think if input one chose the position of the playback head, and input 2 engaged playback upon receiving a gate, it would be super cool!

But also it’s already super cool! Congrats!

cosmicsoundexplorer · 2020-11-08T07:11:25.441Z

I’d love to see this implemented too. Would be a whole heap of fun and also free up my 301 for some other duties.

Hi. This script looks awesome, but I’m getting an error init when trying to launch it, from both the norns and maiden. Is there something I’m missing ? Thanks

coreyr · 2020-11-09T14:17:28.937Z

Are you on the latest norns update? I believe this requires some changes that were made in the October release.

kriskeyser · 2020-11-09T17:47:07.307Z

Given that there’s 26 alphabetically named slots, are there plans to integrate keyboard control of sample playback?

PerVildman · 2020-11-09T18:20:08.500Z

Ohhh. Maybe that’s the thing. I’ll update then

Mad86 · 2020-11-09T18:27:31.858Z

@PerVildman I was had the same problem. New version of the firmware have to solve it

PerVildman · 2020-11-09T20:43:38.061Z

Now the script loads, but I can’t load a sample! I’m getting this in maiden:
lua: /home/we/norns/lua/core/screen.lua:215: bad argument #1 to ‘screen_text_extents’ (string expected, got nil)

Cementimental · 2020-11-09T20:49:15.452Z

This looks amazing but when I go in parameters and choose “save/load” it just hangs the whole parameters section. In Matron I see an endless stream of this sort of thing:

stack traceback:

I’m using a DIY norns shield and the latest update

@Cementimental @PerVildman i believe this error occurs when there are no files available to load so it has trouble being displayed. however, when you start abacus for the first time it automatically copies one file to a directory (~/dust/data/abacus) that can be loaded, so that should be able to prevent the error (i thought anyways).

if you can, try deleting and reinstalling this way:

rm -rf /home/we/dust/data/abacus && rm -rf /home/we/dust/code/abacus
git clone https://github.com/schollz/abacus /home/we/dust/code/abacus

and then run.

later today/thisweek i will fix my lazy initialization with something that is more robust. sorry about that!

@cosmicsoundexplorer @mattymattmatt i feel more confident about the crow support with that explanation! one clarification: which of the following two scenarios do you envision for crow?

input 1 sets position along entire sample. input 2 gates (gate on = starts playing at position and continue playing until end of entire sample)
input 1 sets id of spliced sample (e.g. of the currently spliced ones, labeled A-Z). input 2 gate turns on/off playback of that sample (gate on = continous looping of current sample).

Ukasz · 2020-11-09T22:27:50.168Z

Hell yeeeeah! Looks promising!

cosmicsoundexplorer · 2020-11-10T00:16:30.476Z

Both options have their benefits.

An option for entire sample OR splice id would be amazing.
Kinda like a free run or lock to splice but this would mean only one gate option so Im thinking gate on = starts playing at position and continue playing until end of entire sample.

If only one is possible then I may lean more towards splice id and loop.

@mattymattmatt What did you have in mind?

infinitedigits · 2020-11-10T00:51:20.167Z

i can easily do both options

infinitedigits · 2020-11-10T03:16:00.088Z

@cosmicsoundexplorer @mattymattmatt added crow support!

the parameters for modding it are in global parameters. lmk if it doesn’t make sense, or especially if it doesn’t work. i tested it out by running the functions through maiden because i don’t have crow, but i think it should work!
