Orca - Livecoding Tool

[neauoire]

Nice patch @Allieway_Audio, I’m thinking maybe this should be in the /examples folder.

I just pushed a bit of a massive update this week which contains 2 important new features.

• Case sensitive logic operators(R, M, A, etc.), so you can get a random major by simply doing R(A,H).
• I also added transpose values to the midi operator, so :03H is :04C, and so on. it allows to make really nice arpeggios like:

Let me know if you have any request

I’ve tried condensing your example a bit:

05O..05OS
aV...bV..
..2Kab...
...F.....
..F*.....
7L.......
........0

Really enjoying the midi transpose in the new update! It’s fun to be able to program notes based on both pitch and semantic value, finding surprising combinations/correspondences.

One thing that would really help me ramp up more quickly is documentation of the inputs and outputs for each operator. Does that exist already?

[neauoire]

Hi @jasonw22, yes in the application itself. You can see what each port does.

Operator’s name when hovering on the operator itself.

And individual port names when hovering on the operator’s parameters:

[jasonw22]

That is somewhat helpful!

Still really quite terse though.

Here’s one that is stumping me: V

Left input is V-write, right input is V-read, and there is a V-output.

But I can’t map any of these names to concepts I’m familiar with for reading and writing to and from named variables.

Do I use one of the inputs as a “key” and the other as a “value”, when writing to the variable? And just the “key” when I want to read it? What are valid identifiers for a key that can return the value?

Just an example of one operator that could use a bit more verbose description.

Having a lot of fun though! Definitely feels like an extremely useful sequencer, even after just a couple hours of play.

[neauoire]

That’s a tricky one, maybe someday the V operator will be divided into two different operators, one for assignment and one for read.

I’m open to better port names if you have suggestions, but here’s the idea:

If write is occupied, it writes, what it reads, otherwise it only reads. A bit strange I must admit but I couldn’t find better names. I try to better showcase how the operators work in the /examples.

[jasonw22]

Thank you! That helps. The example where I had seen the V was a fairly dense one, so it was difficult to sort out what was affecting what.

What characters are valid for placing in V-write? I tried using an uppercase A and got the A operator, which didn’t work as a variable name.

[neauoire]

If you do

AV.

You’re basically trying to do (add V<31> 0).

Here I added 2 to demonstrate, (add 31 2) = x<33>:

If you want to assign to a capital letter, just freeze it first with something like H.

If you hover a port, you’ll see who owns it. In the AV. example, you can see that A owns the V location.

[jasonw22]

Aha! H makes an operator not-an-operator. Nice! I didn’t really understand what “Stops southward operators from operating” meant before.

If you hover a port, you’ll see who owns it. In the AV. example, you can see that A owns the V location.

Hmm, now I’m in need of translation again. I assume you mean that if I put the cursor over A I can see that it is in the position of the V-write port? Or did you mean something else?

[neauoire]

In your situation of

I tried using an uppercase A and got the A operator, which didn’t work as a variable name.

If you hover over the V, which is no longer an operator but a parameter to A, it will say A-a which is the a of (add a b)

[jasonw22]

Ah, yes, I understand that. Thank you!

[neauoire]

Anytime Let me know if you have any other question. I’m sure this exchange will come handy to others too!

[mbn]

Yes! I was struggling to nail down V as well. This explains it!

[neauoire]

Pushed a massive update that breaks older patches using A, M, I, and F.

The two right-side ports have been moved to either side of the operator, following the C and D style, allowing for more complex structures like:

I’ve started writing tutorials for each operator:

just needed to let off some fangirl steam and say orca is amazing and it looks so cool on norns wow!!! (i dont have one yet just watching all the ig posts from its yr bedtime)

[neauoire]

wait, where did you see that?
I wanna see that!
