Orca reads from left to right, top to bottom. In your example, in the upper right section you have labeled ’not working’, you’ll notice Va is working. In that instance and all instances in the area below labeled ‘working’ the write variable precedes the read variable.
You can rearrange it so that everything on the left ‘column’ where you are writing variables is placed above where you are reading them. Shift the axis by 90 degrees so to speak.

Hope that helps.

Ugh, yeah…that makes perfect sense. Thanks a lot! I’ll try to rearrange it
EDIT:
I’ve updated the patch here, all suggestions are welcome, it’s probably not the most elegant solution for this technique.

You can already do that :slight_smile: Have you messed with OSC/UDP much?

Also, L4COUR, can I just say how much I appreciate the way you help/encourage/support the others members of this thread. You’re amazing. So, thank you.

Thank you for the kind words @neauoire I am happy to help where I can :slight_smile:

I am still not sure how I would send from Max to ORCA. How would you go about sending OSC from an external source into ORCA?

I imagined that it would just be as easy as this

but this doesn’t work, because the “=”-operator is only for sending OSC, but what if it was more like an I/O port, where it could also receive data on an OSC port, would that be possible to do?

#949

It’s even easier than that.

Send the message write:H;12;34 to write the glyph H , at position 12,34. You don’t need to do anything special in orca, it’ll just write the glyph. So the idea is to draw the glyph at a place that is meaningful in your patch, like a sequencer.

I’m using Max Jitter to receive OSC from Orca. Works with UDP and OSC simultaneously too!

@neauoire, I am truly grateful for the tools you built, especially Orca. I have to say, I look forward to doing more with this and hope to eventually be able to contribute more to the community. Thank you @L4COUR for your posts, good to know there are other Max users who love Orca!

@magfoto yea nice not to be the only Max user hehe. Yea, receiving OSC data sent from ORCA makes total sense, and I really think you can make some quite elegant systems going from Orca to Max. However, going the other way around I believe to be less elegant.

I have tried using the ORCA “write”-function in a patch I developed a couple of months back.

-----------end_max5_patcher-----------

In this patch you have both ORCA and Max/MSP open. in order to control ORCA, you activate the max window and then you can move around inside orca and place all operators, besides from “:”,";" and “=”. While this works, and weirdly enables diagonal movement within ORCA, it also does this weird thing where, as you can see on the screenshot, highlights 3 cells on the X-axis with the middle one being the one that is in the correct coordinate for the, in this case, “J”-operator to be placed within. In this case, I just want the cell where the “J”-operator is located in to be highlighted. Otherwise, writing the parameters for operators like “A” becomes impossible because in placing the parameter you will also delete the “A”-operator.

I don’t know if this makes sense, please write to me if this doesn’t make any sense.

@neauoire if this makes any sense to you, I think that changing this console command so that write would just write an operator where the cursor is placed instead of at a specified coordinate would make a lot more sense, be easier to work with, and result in more elegant systems. I don’t know how one would do it. I do however believe that my issue with the highlights can be avoided if I did not have to specify the coordinates for the write command.

In short: I think the write command should be changed so that you would online have to write

write:H;

and that would result in an operator “H” being written at the current cursor position in ORCA.

Sorry for the long explanation, and I hope it makes sense. :slight_smile:

Why do you use select? would could simply write?

I’ve also pushed a little update(v175) that makes it so wr:H writes at the cursor position.

@neauoire thank you so much, looking forward to try out the new update!

well the reason that I am using “select” is that I tried to create a full on controller for ORCA within Max. I don’t know how useful it will ever be, that said I find it to be an interesting way to explore what ORCA can do. :slight_smile:

#954

Might be useful for disabled people.

yea maybe I haven’t thought of that actually, but yea sure. connecting it with max makes it very easy to develop prototype controllers for it as well with Arduino or raspberry pi. Could be fun to do a project like that!

I figured it out why the placement was weird. As you showed in the video when writing “wr:A;” there are no spaces between the letters. but in the Max patch I had spaces so the message was actually “wr: A;” this meant that it was impossible to place a parameter in the right parameter of the A-operator. But I found out that I needed to use the Max-object called “sprintf” which removes spaces by turning my messages in max into symbols. Everything works flawlessly now hehe :slight_smile:

I will post something with it working soon :wink:

How would Orca go about doing a Program Change via USB to MIDI hardware synth (say, a Volca FM)? Would that be the “!” glyph?

Also, what’s the new “%” glyph all about? How does it differ from the normal “:” MIDI glyph?

Hope Allieway does an updated tutorial! :slight_smile:

#957

i want to pass a midi (or other) operator via a variable. so

.C2
22T:.
aV

Va
(midi channel)

not sure how to do the formatting here but hopefully it’s clear. currently this doesn’t work on Norns or desktop, is there a reason you can’t do it? i find myself muting channels most often if i’m “playing” a patch by just deleting the operator, i’d love to just be able to switch it off and on.

#958

@sisyphus69 Program change in Orca is a bit tricky, you can read the docs here. If you want to animate control change, write use the $ self glyph, like $pg:channel;msb;lsb;program, whenever the $ glyph receives a bang, it will trigger a program change.

@sisyphus69 It’s for monophonic synths, it will cut of any previously playing note before playing the next one. It’s also a good way to limit the cacophony with drums.

you need to send a command to change programs ala: $pg:channel;msb;lsb;program.

for example: " $pg:0;;;63 will set the synth to patch number 64 (without changing the bank)"

more detailed instructions on the Orca GitHub page.

Hi! very new to Orca and had a question re: sending midi to an Octatrack. sorry if this is the wrong place to post this…

Is anyone using Orca + OT? specifically sending Midi from Orca to OT? I have a simple Midi bang in Orca going to OT and it is firing the 1st channel of OT. cool. awesome, really!

My problem is when trying to copy/paste this to trigger channel 2 of OT. No matter what Midi channel I set the “:” in Orca, it only fires the 1st channel of OT. I’ve gone through all of the Midi settings and it looks as though all of the 8 tracks are set to fire on their respective Midi channels (1st track on Midi channel 1, 2nd track on Midi channel 2, and so forth). Messing around with the Auto Channel doesn’t seem to make a difference.

Any idea where I’m going wrong?
I’m using a Focusrite Scarlet 2i4 out of my MBP to send Midi to OT.

edit: I should mention that I first tried Orca with Ableton and had success sending Midi on different channels to trigger different tracks within Ableton.

Somehow I hadn’t thought of sequencing an OT using Orca. woah. I should try that sometime.

As you probably know, the OT MIDI implementation is pretty odd – incoming notes don’t always just trigger “notes” but can start/stop recording, change the active track, and so on. If you’re only sending the same note on various channels, you may actually be sending the note that triggers track 1 regardless of channel (looking at the manual I think that’s MIDI note 24) – could that be what’s happening?

Thanks!!! you’re correct. Once I changed the Midi note being sent from Orca it triggers different tracks. I had a feeling it was some weirdness on OT’s side… I should have looked through the manual more! I’ll do some reading to get a feel for what OT wants for triggers but I’m sequencing 4 tracks in OT right now and that’s enough!

Thanks so much, again!

Awesome! Orca’s algorithmic brain and the OT’s hands-on control seem like they could pair really well, enjoy!
