What Is Tempo Sync; To Turn Tempo Sync Off - Alesis ModFX Metavox Reference Manual

What is Tempo Sync?

In the Metavox, Tempo Sync affects only the frequency
modulation (e.g., vibrato) of the internal waveform oscillator.
Sometimes, you'll want the rate of the vibrato or pitch change to
match the beat of your music instead of being random. For
example, you can set the rate so that the pitch of the SAW wave
changes once per measure, or once per quarter note. The
TEMPO SYNC feature of the Alesis ModFX series not only lets
you set a tempo naturally by tapping on the TAP TEMPO button,
it can automatically adjust its speed slightly relative to a "tapped"
audio input, after setting the basic speed using the TAP button.
To use Tempo Sync:
Set the Metavox's MODULATION section to TEMPO SYNC
mode, as follows:
1. Press the down side of the [MODULATION] rocker switch to
select the next modulation type.
You can see the type of effect by the LED lit next to the name—for
example, TRIANGLE, SAMPLE/HOLD, TRIGGERED and
so on.
2. Keep pressing the rocker switch through all the normal modes
until you enter TEMPO SYNC mode, and then advance to the
type of modulation you want.
Both the Mod Type and TEMPO SYNC LEDs will be lit. For
example, if you press the down side of the rocker switch when you're in
PATTERN mode, the Metavox will go to TRIANGLE/TEMPO
SYNC mode. At this point, the TAP TEMPO LED will start
flashing at the last speed it was set to (or at the default tempo of 120
bpm).
3. Tap the [TAP TEMPO] button several times to set the desired
tempo.
The TAP TEMPO LED will flash in time to the hits. As long as
the [RATE] control is in the center position, the modulation speed will
match the tempo.
4. If the tempo isn't quite right, "tap" a steady, discrete beat on
any instrument connected to the input. The internal processor
will then synchronize the tapped tempo with the audio input.
The processor will make slight alterations to the tempo such
that it stays synchronized with the beat of the audio input.

To turn Tempo Sync off:

Simply press the UP side of the [MODULATION] switch
repeatedly until the Tempo Sync LED goes off, then select the
modulation waveform you want.
