SoundBufBank

This example produces a rhythmic mess of drum sounds. The samples are part of the highly recommended LiCK Project and are subject to its license terms (GPL3). These and other drum kit samples are part of Fiddle's builtin resources.

In the following graph, you may observe that the Session Grid and Remapper nodes are merely icing on the cake. That's true. The example works fine without them, however some prefer icing on their cake and these notes serve to automate/animate the playback rate for the sound buffers.

SoundBufBank Node

Here's a portion of the SoundBufBank node that details a subset of the sound files in our bank. Additional parameters, Rate, Phase, MidiNote are discussed in the SoundBuf example.

You can Add and Delete files in the bank with the associated controls. You can also click on the preview button to audition a sound file in the Sound Player.

In this example our soundbuf bank is composed of 24 sound files, each associated with the 24 adjacent MIDI note to our MidiNote parameter, here C1 (aka note 36).

You can independently position each note in the stereo field with the variable length GainPan parameter. When empty, the output is monophonic and unity gain. When size is smaller than SoundFiles, unassociated channels will appear in the center.

Scale Node

Here is the Scale node that produces the notestream.

The key ingredients are:

Name is set to Chromatic which means that any of the semitones in an octave are legal.

Octaves 2 will produce 24 notes from Base through Base + 23.

Base is set to 36 corresponding to SoundBufBank's MidiNote value of C1 (above).

Beats causes notes to be produced at quarter-note time intervals.

SampleMode is to to Random to produce a random note from our 2 octave collection.

The icing

Here's an image from the Session Grid Node and the autoRate.fgrd file included in the example. This picture repesents the Rate parameter that is delivered to the SoundBufBank by the SessionGrid node. Note that we provide values over the range of bar 3 through 13. The Rate values (and all values in the SessionGrid) are normalized to be between 0 and 1. At measure 8 and 13 we see high values and 5 and 11 we see low values. These values are remapped by the Remapper Node to produce rates in the range of .75 and 1.25. To play with this range, just click on the node and modify its OutputMin and/or OutputMax parameters.
