Making Notes (Basic)

Patch a sound source into the Audio In

jack, and patch the Audio Out jack to your

mixer or amp so you can hear it on

speakers or headphones. When choosing

the sound source, try to find something that

makes a continuous tone or drone, such as

a VCO like the Ensemble Oscillator.

When Cycle is on (button is shining

orange), you should hear notes being

played at a steady tempo. The notes should

have a sharp attack (quick fade-in) and

longer decay (slower fade-out).

Try moving the Rise slider up and listen to

how the sound fades in more slowly. Then

move the Fall slider down and hear how the

fade-out gets faster. Continue to experiment

with the slider positions, listening to how the

sound and tempo changes. Try flipping the

switches to Fast and hear how much faster

the envelope gets.

Next, patch the Env jack to a modulation

input on the sound source. For example, if

you're using the Ensemble Oscillator, try

patching it to the Warp jack. For other

VCOs, try a PWM or wave-shaper input.

Adjust the Env. Level slider to control the

amount of modulation. When the slider is all

the way down, you should have no

modulation.

Making Notes Using External Triggers

So far in this patch, the tempo of notes has

been linked to the rise and fall times of the

envelopes. It's not possible, for example, to

have short, quick notes at a slow tempo.

By turning Cycle off, we can use the

Trigger jack to control the tempo with an

external module.

See the patch on the left. Press Cycle to

turn it off. The sound should stop. Patch a

clock or trigger sequence into the Trigger

jack. You could use the output from a clock

module like the QCD, RCD or SCM, or

perhaps the gate output of a sequencer.

You could even use an LFO waveform such

as a sine wave, as long as the signal peaks

are greater than 2V.

When the Trigger jack receives a trigger,

the envelope will fire one time. Play with the

external module's tempo to hear how the

notes keep their shape at all tempos. You

can even make the notes "run together" by

setting the tempo faster than the note

duration.
