aubio is actually a C library with python bindings.

aubio by itself works fine on norns. the dependencies for the python tools are a little heavier than i would recommend for the limited disk space on the norns system.

i guess a case could be made for linking aubio into matron and providing lua bindings. i’d be happy to review a PR for that.

or, simpler (in a way): aubiocut is standalone, it can be executed from a norns script.

Just a note, this sounds really awesome, I can’t wait to play with it if you get it going!

Ah yeah didn’t think about the disk space it would need. Guess there maybe isn’t the need for it as its a pretty fast process from the command line! I also sometimes use the cuts with the tool Sox to randomly shuffle them back into concatenated files which is fun. All of that from one script could be cool. However I have no idea how to do that! thanks.

I posted a link to a recent supercollider tutorial on pulsar synthesis over in the granular theory thread, which got me thinking about how cool it would be to have something in the vein of Roads’ PulsarGenerator or the recent NuPG on Norns.

I am working on something like this. I was going to just add it to mangl, but decided it would be it’s own thing.

Can’t wait for this. I’m sure it will be stellar.

I have to say that was before i tried timber, wich i know by now is massive and super fluid in the sample edits. It could be build on for such ideas, i think its one of the finest fundaments for sample playing with a grid. Has a small mod matrix similar to parts of the blofeld.

Someone should make a little typing game with the HID library! It’s on my list or whatever but that list already looks too big to comprehend so I wanted to throw it out there :slight_smile:

Hey guys I just thought about shortcuts. It could be nice for example to lower the volume by holding 3 buttons? Or something like this. To avoid menu diving. What you think?

Hey all.

I’m looking for a more traditional sequencer on the Norns + Grid platform, and am struggling to find one. It’s not a big deal for me, I’m just curious if I’m missing some gem here in my explorations.

To be clear, this is what I mean:
Like Awake, but polyphonic and with options for more than one pattern (without loading a new preset), and potentially also to be able to scroll up and down for more elaborate harmonics (like the Animations script).

An open-ended step length per pattern would be cool, Deluge style, but I’d settle for a set length between X to Y, if there was pattern switching going on.

I’m finding a few that do something or variations on these, but not a sequencer that’s just a no nonsense polyphonic sequencer.

If anyone’s been on the Deluge here, I guess what I’m after, is a one track Deluge sequencer, where I wouldn’t find defined pattern lengths and just one track a limitation.

Kria MIDI might scratch your itch but it’s probably not as straightforward as you want… until you learn it!

Thank you :slight_smile: you know, I think I missed that one. I’ll give it a go. Much appreciated. I don’t mind the hassle, as long as it makes sense in the long run.

@tehn is finishing up a release package for norns 2.4. this includes @artfwo’s new clocking system which makes it much cleaner to write things like a sequencer with variable step length, clocked by arbitrary source.

so while i’m not familiar with how exactly the deluge works, given a detailed functional spec for your dream sequencer, i’m confident that someone here can code it up pretty quick. what i’m reading here isn’t quite enough to go on. (in other words, i think the design spec is the bulk of the work, and the coding should be quite simple.)

nice - I’ll get this and Crow support (arrives Monday!!!) in to Kria MIDI soon - probably over the next week depending on other work

Very interesting. My daytime job is just that, to produce functional designs for the purpose of development and scheduling. I’m in the borderland between creative and producer, speaking the language of concept and design and translate it into technical and development terms.

I wonder if such a skill would be of use in this forum? I could spec out exactly what I mean regarding this sequencer, for example, not just as an idea but as a specification that would make sense for a developer.

I tend to think in terms of minimum viable product, but always build on platform, so that in terms of features, a first release wouldn’t have to contain much but the idea around it would be for such a platform so that adding ideas would be more about if it’s right or not for the application, not so much “Oh, it can’t be done because we only used very specific solutions to solve very specific problems.”

I also find that new ideas emerge in interesting ways when you approach product development this way, since once the platform has enough general solutions in place, the ways you can combine them into things you never thought of, leads to features you’d never thought of before but are awesome in their own way.

yeah, super interesting!

i’d say: absolutely. norns is a fun platform to program, it’s pretty easy to learn, and i think for many coders, it’s very satisfying to “solve” the puzzle of implementing a spec. (that satisfaction being amplified many-fold if the result is useful for creative purposes and immediately serving a need in one’s extended social circle.)

there’s definitely room in this forum for some kind of matchup between spec-writers and implementers. (the “Norns: ideas” thread is a good start, but as you are aware, there can be a great gulf between an idea and a workable idea.)

so yeah, give us that MVP scope! we’re ready

Oh man, I got that vibe like when I got my first job in the video game industry. Love it :slight_smile:

So I’ll cook something up, won’t be expecting anyone to execute on it, I’ll do it because it’s fun, and then we’ll see where it goes.

I’m certainly interested in this. As well as my things for Norns (primarily Islands right now but there will be more) and the stuff I make for my own use I also make commercial music software a Pagefall limited - currently just on iOS but the next app will be Mac and Windows (and will be out in the next month hopefully). When I focus on enterprise software (which has tended to be my day job) I’m always interested in the “job to be done” rather than technology for technologies sake. I think the same principle largely applies for music software BUT there is an aspect of “is this algorithm/technology/artefact/whatever” interesting in a musical sense and can I parameterise it. One reason my music practice tends to involve a lot of coding is that I’m trying to capture that.

So yeah - can’t promise anything more than conversation but you never know…

Conceptually, Awake on Norns is the Deluge, where each push on the vertical row is a note that’s part of the scale.

As a concept, what’s missing is polyphony, access to notes above and below the default eight grid (which to some extent Animators solves in a fashion similar to Deluge, though it cycles rather than transports, and the octave triggers in Awake’s second track, of course), a step count beyond the sixteen and multiple patterns. Deluge allows for endless pattern length, which sounds like a shangri-la in theory but it’s in practice pretty cumbersome. If you look at patterns like bars in sheet music, and instead make it easy to move between patterns and potentially chain them together, not entirely unlike Novation’s approach with the Circuit and the Launchpad Pro MK3, it actually makes more sense to divide it like this and then instead allow for structuring them in creative ways.

I’m a classically trained pianist to begin with, before I got into this kind of music, and the pattern structure with looping and rephrasing makes total sense to me. A sonata works after the same principle. Play until this point, repeat once and after that, move to the next point. Repeat THAT section, then proceed. There’s even instructions in the note sheets on how to approach the same section in different ways, depending if you’re on the first or second loop.

So pattern structure in itself for many kinds of musicians, is a structure that just makes sense. It’s when you need to take all the pieces and make them into something bigger, where many sequencers fall short. The cry from the Elektron community after song mode into the newer devices show to some extent that structure beyond being creative within 64 steps is something almost everyone wants, even if your act is all improvisation or very defined.

So yeah, that’s what I’m aiming for. We’ll see what comes out of it.
