1. A digital tone synthesizer having stored digitally sampled note data, the note data having been sampled at a sampling frequency F, with a sample period of 1F, the digital tone synthesizer comprising:

  • a DSP clock operating at a DSP clock frequency;

    a slot count incrementer for incrementing in a slot counter a slot count of a selectable number of slots n, each slot having a slot duration defined by a selectable number of DSP clock ticks T;

    a system clock operating at a system clock frequency equal to a whole number P multiple of the sampling frequency, the system clock producing system clock ticks;

    a reset counter for counting P system clock ticks and thereupon effecting a reset signal to the slot counter.
