that can be used as waveshapers by the Waveshaper Sound. For example, if you typed in the coefficients 5, 4, and -2.5 you would be specifying the polynomial 4 + 4x − 2.5x 2 If the interval you enter is -1 to 1, then the editor will evaluate this polynomial for x values ranging from - 1 to 1. Random This generates a random waveform whose amplitude ranges from -1 to 1. Specify a seed so that you can get repeatable results. Change the seed when you want to generate a different random waveform. To generate different kinds of noise, modify the Random Program template. Window Selection This template applies a fade-in and fade-out curve to the selection in the graphic editor. The Transition Duration is the duration of the fade in and fade out. Viewing the Template Code The hierarchical list of templates also contains the subheading Programs, which contains Smalltalk code for each of the template types. If you like a particular template but want to make a minor change in the algorithm, you can modify (but not save) its Smalltalk implementation. If you are not sure you understand one of the templates, you can read its Smalltalk code to see what it does. If you want to write your own Smalltalk code for generating a wavetable, you can use the existing Smalltalk programs as models or starting points for your own code. To save your modified wavetable generator, copy the text and paste it into a newly created text file. Wavetables Provided with Kyma Compress Control When used in a MultiplyingWaveshaper, this waveform can be used to do computationally inexpensive compression and expansion. Think of the curves as output-attenuation-as-a-function-of-input-amplitude. To create new curves, use the InputOutputCharacteristic Program template in the sample editor. C5_01_1 These are typically used in FunctionGenerators to generate envelopes or “control signals” for hot parameters. If you want a periodically repeating control signal, use one of these samples in a low frequency oscillator. To generate your own, use any of the templates in the sample editor or modify template code to compute an arbitrary mathematical function and store it as a sample. Exponential ExponRev FourExpons 504
EX GA FullRamp Gaussian Ramp Random The RE analysis tool separates a sample into two parts: a time-varying filter (the resonator) and the signal (the excitation) to feed through this filter to recreate the original sample. These files are the excitations from various samples, and can be used as an input to the REResonator Sound. The GA (group additive) analysis tool reduces a spectral analysis file (consisting of potentially hundreds of sine waves with different frequency and amplitude envelopes) into a smaller set of more complex waveforms with corresponding amplitude envelopes. These files are derived from various musical instrument samples, and can be used in the Analysis0 or Analysis1 parameter in the GAOscillators Sound. This is a display of a GA file for a harp pluck. The GA analysis tool reduced a spectral analysis file with 128 partials into three complex waveforms (shown above in the left two-thirds of the display), three corresponding amplitude envelopes, and a frequency deviation envelope (all shown in the right one-third of the display above). Impulse Responses These files contain the responses of various filters to an impulsive input. They are typically used in FunctionGenerators, Samples, or Oscillators. ah ahhhhhhh FilteredPulse 505
