On Windows, the sound output level is set using the Sounds and AudioDevices setup (Start - Control Panels - Sounds and Audio Devices).If you are still are not hearing anything, choose DSP Status from the Options Menu andverify that Core Audio Built in Controller for Macintosh or MME driver for Windows isselected in the Driver pop-up menu. If it isn't, choose it.SummaryA signal network of connected MSP objects describes an audio instrument. The digital-toanalogconverter of the instrument is represented by the dac~ object; dac~ must bereceiving a signal of non-zero amplitude (in the range -1.0 to 1.0) in order for you to hearanything. The cycle~ object is a wavetable oscillator which reads cyclically through a list of512 amplitude values, at a rate determined by the supplied frequency value. Signalprocessing is turned on and off by sending a start or stop message to any dac~ or adc~object.• Close the Patcher window before proceeding to the next chapter.See Alsocycle~dac~Audio I/OTable lookup oscillatorAudio output and on/offAudio input and output with MSP61
