The sigv light module when loaded (ºn) has the following default parameters:

º a 1 - activation off (º a 1), to activate and turn is (º a 0)
º v 0 - geometric object of light source off (º v 0)
º r 0 - random colorizer on (0), to deactivate is (º r 1)

The ∞ chao commands sequence a set of preset instructions for the Lorenz attractor command and shader (lz). Original experiments can be found here: https://magfoto.any.org/live-coding-chaotic-oscillators.
Initializing an lz module has the following defaults: ∞ 0, and its engine starts with the following: ∞ s

The MAT operator processes textures loaded into containers tex0, tex1, tex2 and tex3. These textures can be loaded into sigv using the command fpic read for tex0, fpic 1 read for tex1, and so on. Once images are loaded as textures, the | d 0 command will load tex0 on the primitive of focus (… f 0, for instance places focus on a loaded geo primitive).

The TRANS operator commands are tested to work primarily with parametric geometries such as geo, proc, nurbs, and plato, but as well with 3D model primitives like model, and b0..b7. The ^s (shape) operator targets the 10 shapes of geo gs1 (^ s 1) or geo gs2 (^ s 2):
0 - sphere
1 - torus
2 - cylinder
3 - opencylinder
4 - cube
5 - opencube

8 - cone

The ß operator represents the sigv spk sampler module. Using the Max mc.play~ object, ß o 4 in Orca will trigger a dialog box to select an audio file and store it in buffer, and a ß 4 would trigger the sample to play. Being a sonic module, the spk requires the starting up of the aio engine, which in o-sigv can be triggered with a _ 1 1 command (see AUDIO below).
By default, when an spk is loaded it is automatically connected to the default MIDI. This means that form our example above, if a MIDI channel 4 message is received (i.e. a bang of : 3 1 C in Orca) will trigger the spk sample 4, just like sending a bang to ß 4 in o-sigv. To turn off this feature, a bang to ß m 0 does that, with the option to always send a bang to ß m 1 to turn it back on.

Using sonic command midi vst plug and a number for a buffer container (there are only four midi channels for a VST: 1, 2, 3, and 4), allows you to choose an VST instrument from your machine. After which, writing the Orca characters _ v 0 2, (notice channel number is 0) opens your instruments GUI (in this case the VST instrument in channel 2).
… n, z, and f, are SYSTEM operator commands that refer to primitives and modules listed as follows:
0 - geo
1 - proc
3 - model / b# (# can be integers 0 thru 7, like b1)
4 - nature
5 - wrld
6 - lz
7 - midi
8 - spk
