Abstract
The invention concerns a circuit for an electronic musical
instrument which comprises a clock generator whose clock
rate is variable in accordance with sound frequencies to be
generated. A wave form memory contains scanning values
of a wave form indigital format and may be addressed by the
clock generator output signals. Data retrieved from the
memory are processed by a digital to analogue converter by
means of which the read-out scanning values are converted
into analogue signals and processed in following circuits so
as to produce audio-signals to be sounded. The wave form
memory holds the scanning values of several periods of a
note including its release section, and under predetermined
memory element addresses of the wave form memory
command words are memorized and if these are read-out a
command signal is passed to the clock generator so to set it
onto an address under which in the wave form memory the
same scanning value as prior to said command, however, in
the release section of the envelope, is read while the digital
analogue converter is disabled for the command words.
