Trapezoidal wavetable (multichannel) trapezoid~ is a trapezoidal wavetable with signal inputs to change ramp up/down phase position. The default lo/hi points are 0. and 1., but may be changed using the lo/hi messages. Cycling '74 MSP oscillator MSP Functions (signal) Input TEXT_HERE (signal/float) Point 1 TEXT_HERE (signal/float) Point 2 TEXT_HERE (signal) Output TEXT_HERE Ramp up value A floating-point value can be used to specify the ramp up value. The arguments 0. 0. produce a ramp waveform, and 0.5 0.5 produces a triangle waveform. Ramp down value A floating-point value can be used to specify the ramp down value. The arguments 0. 0. produce a ramp waveform, and 0.5 0.5 produces a triangle waveform. Function depends on inlet In left inlet: Any float or signal or an input signal progressing from 0 to 1 is used to scan the trapezoid~ object's wavetable. The output of a phasor~ or some other audio signal can be used to control trapezoid~ as an oscillator, treating the contents of the wavetable as a repeating waveform.

In middle inlet: The ramp up portion of the trapezoidal waveform, specified as a fraction of a cycle between 0 and 1.0. The default is .1.

In right inlet: The ramp up portion of the trapezoidal waveform, specified as a fraction of a cycle between 0 and 1.0. The default is 0.9.

In right inlet: The ramp up portion of the trapezoidal waveform, specified as a fraction of a cycle between 0 and 1.0. The default is 0.9. Maximum value for signal output Sets the maximum value of trapezoid~ for signal output. The default value is 1.0 Minimum Value Sets the minimum value of trapezoid~ for signal output. The default value is 0. A signal which corresponds to the value referenced by the trapezoid~ object's input signal. If the output of a phasor~ or some other audio signal is used to scan the trapezoid~ object, the output will be a periodic waveform.
