|
### Orca |
||||
|
|
||||
|
There are many implementations of Orca. |
||||
|
The ones that work for this workshop are: |
||||
|
|
||||
|
* JS/electron: https://github.com/hundredrabbits/Orca |
||||
|
* ANSI-C: https://github.com/hundredrabbits/Orca-c |
||||
|
|
||||
|
#### Easy setup |
||||
|
|
||||
|
The quickest way to get started on any platform is to just use the 'fancy' electron framework version. I recommend doing that for the workshop, to avoid the "install-party" effect. |
||||
|
|
||||
|
* Binary release: https://hundredrabbits.itch.io/orca |
||||
|
|
||||
|
#### Advanced Setup |
||||
|
|
||||
|
My favourite setup though, is running the ANSI-C version in [Cool-Retro-Term](https://github.com/Swordfish90/cool-retro-term) |
||||
|
Orca AND Cool-Retro-Term are available in many package manager, have a look in yours. Maybe you are lucky... |
||||
|
|
||||
|
### Pilot |
||||
|
|
||||
|
Orca cant make any sounds, it can only generate MIDI, OSC or UDP output. |
||||
|
Pilot is a 'companion' program (from hundredrabbits as well) that is a fun little synthesizer and is very easy to use with orca over UDP. |
||||

|
## Language Quick Overview |
||||
|
|
||||
|
* Esoteric Programming Language |
||||
|
* 'Frame-Oriented' language |
||||
|
* 26 operators `A`-`Z` |
||||
|
* Uppercase operators execute on every frame |
||||
|
* Lowercase operators execute on a 'Bang' |
||||
|
* Data is just Base36 numbers '0-9' and 'a-z' |
||||
|
* I/O: no I just O. MIDI/OSC/UDP |
||||

# Tutorials |
||||
|
|
||||
|
## Tutorial: Bangs and Sounds |
||||
|
|
||||
|
### 1. Bangs |
||||
|
|
||||
|
Operators you learn in this chapter: |
||||
|
|
||||
|
* 'D' - Delay, bang periodically |
||||
|
* |
||||
|
|
||||
|
|
||||
|
### 2. Sounds |
||||
|
Operators you learn in this chapter: |
||||
|
* `;` - UDP |
||||
|
|
||||
|
for synthesizing the actual waves we are using 'Pilot', a soft-synth which we control with UDP packets. |
||||
|
So, the commands we send using the UDP output operator are actually Pilot commands, not orca. |
||||
|
|
||||
|
Pilot commands are 3-5 'bytes' long, where the first 3 are required. |
||||
|
The format is: `CH` `OCT` `NOTE` [`VOL`] [`DECAY`] |
||||
|
|
||||
|
Where: |
||||
|
* `CH` - Channels 1-f exist, they all sound different (and they are monophonic) |
||||
|
* `OCT` - Around 8 octaves should definitely exist |
||||
|
* `NOTE` - Note names where Upper-case are white keys and Lower-case are Black-keys |
||||
|
* `VOL` - The Volume 0-z (even though the doc says 0-f, but hey we love clipping dont we?) |
||||
|
* `DECAY` - The 'length' of the note, 0-f (?) |
||||
|
|
||||
|
Example: |
||||
|
`;13C` - Pilot plays note 'C' of octave 3 (default volume and length) |
||||
|
|
||||

### Putting It All Together |
||||
|
|
||||
|
|
||||
|
## Tutorial: Flying East Scope |
||||
|
|
||||
|
### 1. Arithmetic |
||||
|
|
||||
|
Operators you learn in this chapter: |
||||
|
|
||||
|
* `C` - Count (speed / modulo) |
||||
|
* `I` - Increment (increment / max) |
||||
|
* `R` - Random (min / max) |
||||
|
* `A` - Add (operand/operand) |
||||
|
* `B` - Subtract (operand/operand) |
||||
|
* `M` - Multiply (operand/operand) |
||||
|
|
||||
|
### 2. Variables |
||||
|
|
||||
|
Operators you learn in this chapter: |
||||
|
|
||||
|
* `V` - Variable r/w single (Write: name / val | Read: - / name) |
||||
|
* `K` - Kontakt read multiple (Read: count / names) |
||||
|
|
||||
|
### 3. Flying East |
||||
|
|
||||
|
Operators you learn in this chapter: |
||||
|
|
||||
|
* `X` - Write |
||||
|
* `E` - East |
||||
|
|
||||
