Abstract
An electronic musical instrument has a plurality of oscillators. Each oscillator reads out segments of a waveform stored in memory using a random selection method. In one method the loop or start address is selected at random and the selection of a new address may be one cycle from the loop address or may be a repeat of the prior end address. In another method, both the loop and end addresses are randomly selected. Further, the end address is repeated a number of times determined randomly within a defined range of numbers.
