That’s something a number of folks in here have been working on in Max and PureData and something I’ve been meaning to get back to scripting, myself (in Python, for now, and hopefully in VCV Rack, at a later date). In short, it can be accomplished over UDP (and maybe OSC?) but is otherwise nontrivial.

Very late to the ORCA party but been blown away with how fun it is.

I just made a tutorial on how to use Orca with Pilot which is a synth engine built for use with Orca and Cassetter which is a sampler build for use with orca. Covers most of the basics and some intermediate functions of you’re returning or just stating off with it! Check it Out!

How is K being used?

#1122

I ended up writing a quick, crappy Python script for controlling Orca via the OP-1.

Awesome! This will be extremely helpful to look over.

I’m wondering… Is there a way to offset a note by a semitone via math (e.g. something like the A operator, which doesn’t appear to offer that functionality)? What am I not seeing here?

Another fun ORCA study, this time using the multi-map feature on the Digitone.

In my effort to make a mod tracker in ORCA I somehow managed to create a generative granular noise source

Is there a way to transpose midi notes by for example a fifth?

#1128

Did you find a way to do this?

#1129

You can do this with addition programmatically lots of different ways. Maybe I’ll post some examples later if someone else doesn’t beat me to it.

Cool. So the letter notes have numerical values that can be used? Looking forward to examples. Thank you.

#1131

yes, exactly. Adding 1 to b will give you c.

example

in this example variabl “x” is normal and variable “y” is pitched up by 3 steps.

.C5.............
.35Tcadgf.......
.xVg......Vx....
..........gA3...
.........yVj....
................
.........D1..Vx.

I’ve tested this now and it doesn’t work as expected. a “C” transposed 3 steps becomes an “F”. So the numerical values is added to the letter. C, D, E, F as opposed to semi tones C, c, D, d. Maybe I’m doing something wrong?

.D..3AC.
.*:02F5.
#1133

That’s why I asked here in the first place. Diatonic math is straightforward and I was wondering whether there was a way of working in the chromatic scale that I simply didn’t see.

#1134

Yep, I see the problem now. “a+1” is treated numerically. There is no way I know of to get smaller intervals of notes through math.

#1135

One way to use the addition operator to increase a note is to set out your scale in a table and then do math on the index. Here’s a quick example:

#Base#......
.4C8........
aV0.........
............
#Up.a.3rd#..
.Va.........
.0A3........
bV3.........
............
#Eb.Scale#..
#Notes#.....
.Vb.........
.38TdFfgaBcd
.0Vg........

In this example getting the “a” variable of the table gets you the unaltered scale, and the “b” variable gets you the third. You have to mess around with octaves a bit, but this mostly works.

what would be a good way to use the web browser version of Orca?

I want to be able to mess around making sequences on my work computer so when i get home I can export them (another thing i haven’t really figured out) and then open them on the norns once i get home and run the midi out to my synths. Even if i have to change midi ports, that’s not a big deal. Or, even just to get practice, I think it would be very convenient. I’m typically not able to install anything on the work computer. So even if I could figure out how to route Midi (Webmidi?) or UDP to Pilot via Chrome, I wouldn’t be able to run Pilot unless there was a browser version of that as well.

Is there maybe a browser synth worth using? and what would be the best way to make a connection between the browser Orca and a browser synth? There is no internal sound engine, correct?
