Sampler Oscillator

Name

Sampler Oscillator:

2135 1133
sampler oscillator

Description

The Sampler Oscillator is the built-in EigenD sampler plug-in which uses the 'SoundFont' file format. In its most common configuration it is combined with the Cycler Agent for polyphony and damping management and also the AHDSR Agent for envelope generation.

Ports

Velocity sample

  • Name:

1417 1275
velocity sample

  • Input, Set
  • Type: Number
  • Range: 1 to 1000; default = 4

The velocity sample is a value set by the user to determine the number of samples taken to calculate velocity.

Velocity Curve

velocity curve

  • Input, Set
  • Type: Number
  • Range: 0.1 to 10; default = 4

The velocity curve detremines the prevalence of samples in a multi-layered sound. 1 is linear, values below 1 produce a concave curve (attenuating the velocity) and values above 1 produce a convex curve (boosting the velocity). The default value is 4.

Pressure input

  • Name:

128 116
pressure input

  • Input
  • Type: Number

Nouns

Sample:

A Sample refers to the internal representation of a SoundFont within the Sampler Oscillator (as opposed to a reference to a particular SoundFont), as something you could 'browse' for example.

Verbs

First:

7567
first

The 'first' verb is used to choose the first SoundFont in the SoundFont database as the 'sample' within the Sampler Oscillator.

172
next

The 'next' verb is used to choose the next SoundFont in the SoundFont database as the 'sample' within the Sampler Oscillator.

where X is the number of your desired Sampler Oscillator.

Setting the velocity sample

To set the velocity sample, use

1417 1275 23 ? 67
velocity sample to X set

where X is the number of your desired velocity sample.

Setting the velocity curve

To set the velocity curve, use

1417 1512 23 ? 67
velocity curve to X set

where X is the number of your desired velocity curve.

Setting the detune input value

To set the detune input, use

2312 116 23 ? 67
detune input to X set

where X is the desired detune.

Setting the transpose

To set the amount of transpose, use

1238 23 ? 67

8822 5584 67
fade enable set

To use the first verb within the Sampler Oscillator, simply use

7567
first

Browsing SoundFonts using the EigenBrowser

To browse SoundFonts, make sure you have the EigenBrowser open, then use

8777 5
eigenbrowser hey

2135 1133 ? 1275 413
sampler oscillator X sample browse

Naming a SoundFont

To give a SoundFont a Belcanto name, make sure you have the EigenBrowser open, then use

8777 1131
eigenbrowser listen

2135 1133 ? 1131
sampler oscillator X listen

where X is the number of your desired Sampler Oscillator. This brings the EigenBrowser and the Sampler Oscillator into the conversation. You then need to select the SoundFont you wish to name in the EigenBrowser and use

414 23 ? 123 74
selection to X name ify

where X is the desired Belcanto name. The Belcanto name can incorporate any words from the Belcanto dictionary, you can also make up your own belcanto word. If you are using the Interpreter Keygroup simply play in your new word, if you are using the EigenCommander type ! followed by your new sequence, for example - 'selection to !1234 name ify', or 'selection to !8888 name ify'.

Choosing a SoundFont

To choose a SoundFont from the EigenBrowser, making sure you have the EigenBrowser open, use

8777 8716 2135 1133 ? 5
eigenbrowser , sampler oscillator X hey

414 122
selection choose

where X is the name of your desired Sampler Oscillator. To choose a SoundFont with a predefined Belcanto name, use

8777 8716 2135 1133 ? 5
eigenbrowser , sampler oscillator X hey

? 122
Y choose

where X is the number of the desired Sampler Oscillator, and Y is the desired Belcanto name.
