FUNCTIONAL DESCRIPTION

OSCILLATOR CIRCUIT

The oscillator frequency is used as a time for tone and beat

music.

generators.Its accuracy affects the quality of the

TONE GENERATOR

Tone Frequencies are oscillator frequencies- M,where m is any even number from 64 to 256. Within a melody 14C

scales can be selected including Pause code and End code.The tone generator is a programmed divider,The Range

of Scales is from C4 to C6 and range of frequency varies from 258Hz to 23768Hz.

RHYTHM GENERATOR

The rhythm generator is also programmed dividers. It contain 15 available rhythms as follows :1/4,1/2,3/4,1,1-

1/4,1-1/2,1-/3/4,2,2-1/4,2-1/2,2-/3/4,3,3-1/4,3-1/2,3-/3/4.Four rhythms can be selected from these.

MELODY ROM

The Mask Rom can memorize 64 notes with 6 bit.4 bits are used for controlling the scale code and 2 bits are

used for controlling the rhythm code.

TEMPO GENERATOR

There are 15 available tempos in the Contek UM66T series.The 15 tempos are:128,137,148,160,175,192,213,

240 , 274, 320,480,640,960,1920 J/minute.
