Play music with video samples

AVGRANU

Play music with video samples. Realize live montages and generative installations. Choose sounds and vidéos and build interactions between

• Two audio/video tracks
• Sound analyse modules,
• Time stresh modules
• Synthetizers
• Step Sequencers

Step sequencers

Two Step sequencers generating number sequence according to

• A number sequence of time
• A number sequence of itération
• A number sequence of progressivity
• A number sequence to be added or subtract

Apply the datas to:

• The position of the loop (4)
• The Pitch and the speed simultaneously (5)
• The speed only (5) to the pitch only (6)
• Synthetizers (7)

$ = value, each step got a value

[=IT]

• Play all $ of time (all $ of Step sequencerT) at each value of the general Step Sequencer (top line) ... allT $ / G $
• If it is not triggered = Play a $ of the Step sequencerT at every $ of the general sequencer Step ... T $ / G $

[≠IT]

• Change steps on the step sequencer (s) in accordance with a fixed $ of time (1000) by default).
• • Column still on the right: go to the value gradually (1000) by default)

[%T]

• Divides time by the $ from Step Sequencer IT ... T $% IT

[/Tb/]

Receive the time of Step sequencer B

[A]

On/off

[next]

Step forward

[ø]

Reverse steps off and steps on

[><]

Send a step on two opposite values

[>>]

Move linearly on the sequence.

• One step all 6.25$ (100%16 = 6.25)
• if the tempo = loop lenght of the sequence%10

[O]

Turn this step mute

Selectors and modulation

Choose position(s) to the starting point of the loop

• Add value to this position(s)
• Move the postion(s) along the whole sequence
• Apply enveloppe to sound track and opacity to video layer

Gate

Set the position of the playhead where to start the playback loop

[raw]

raw data A or B

[A@]

Make a loop on the fly and change position with Step sequencers

[@re]

Call back the loop made in [A@]*

*When released, read what is after the loop chronologically

or with the [@A] mode go back where you were
at your last [@re]

[>ø]

Press on, press off (midi mod)

[loc]

Lock selected source (midi mod)

If you choose to send files triggered by A or B or randomly with BB or BB1 the sample sent will be played at its beginning

[Trg] and [Bng]

Auto-receive On/off step and send enveloppe to the sound selected.

[Trg]

On/off step

[Bng]

send enveloppe to the sound selected

[<<<]

Send on/off step and set enveloppe from sources selected in s&p, speed, or pitch

[ø]

Trigger the Step sequencer [A] or [B] as selected in s&p, speed, or pitch

Audio modulations

• Speed and pitch (50 = 0= stop, 75= go forward , 25= go back)
• Speed only (50 = 0= stop, 75= go forward , 25= go back)
• Pitch only (0 = default)

Left ’s 2 columns

• select data source

[bck]

Back to default $ after selection released

[O]

Go back to default $

slider

set value

Choose data source

[A], [B], [‘’a] or [‘’b]

Right’s 2 columns

• Module data from the left ’s 2 columns

[44]

choose between 44100/88200 hz

[O]

Go back to default $ slider: set modulation value

Choose data source

[A], [B], [‘’a] or [‘’b]

Time stretching until drone

Advance your number sequence, pattern, over the entire sample

Make the pattern you are making with Stepseq A or B sliding along the loop lenght more a less rapidly.

• Select entry point in the sample
• Select exit point
• Select strecthing value

Analyse silences and attacks in the audio signal of sampler or synthetizer

• Send the values as

[‘’a] or [‘’b]

trop-simple

Un projet simple

• Alors tu fais le malin!?
• C'est dur? Tu veux dire duRE!?
• D'écrire
• Comme çà ?

Écrire un manuel en Markdown

• C'est pas
• Si compliqué

Tout le monde peut participer

• Parce que c'est trop simple

La syntaxe ?

• Elle est décrite dans les spécifications de Markdown (y'en a pour 25 minutes de lecture)

Comment participer ?

• Il faut cliquer sur le stylo là haut pour éditer la page
• Il ne faut pas hésiter à regarder le code source
• Il est possible décrire des livres entiers en utilisant ce principe
