Fundamentals

12 Function Generator Applications

50 EMU Systems, Inc.

 Two-Speed Sequence - This sequence

changes rate every other time it plays

through. The flip-flop sets and resets

every other time it is pulsed with the

function generator gate. The Cord

amount from the flip-flop controls the

amount of speed variation.

(Note: The -DC Cord is necessary because

the flip-flop input needs to go positive from a

negative value.)

 Multi-Speed Sequence - If you want

to control the timing for each step in

a sequence, two function generators

can be used. Function Generator 1

controls the pitch and Function

Generator 2 controls the length of

each note.

Two function generators will remain

in sync if their initial rate, length and

direction are the same, and if the

modulation is identical for both.

 Sample Re-triggering - The Trigger Out of the

Function Generator is ideal for re-triggering

samples. In fact, the trigger out can be used just

for sample re-triggering without using any pitch

control. Use Sample Retrigger (-) to trigger on the

note.

(Remember, samples to be retriggered MUST

have a loop.)
