Ploytec ONE.2 Instruction Manual

www.ploytec.com

We thank you for purchasing the ONE.2 and hope you are happy
with this innovative product. Please read the following instructions
carefully to learn how the device functions. ONE.2 is a musical
instrument, which requires practice. With this instrument, you will
be able to create incredible music.

Getting started

As soon as you tap the foot switch, ONE.2 is activated and awaits another
tap for 2 seconds. Right after the second “tap”, ONE.2 starts transmitting a
so called “MIDI Clock” signal. This information synchronizes your synthesiz­er, sequencer or computer software to the tempo.

The ONE.2 calculates the tempo with the
time between the two taps on the pedal
and bases the calculation on a quarter
note. Example: if there is 1 second be­tween the two taps, this would equal
60bpm: 60 beats per minute. Half a sec­ond means 120bpm, 2 seconds 30bpm,

etc.

In case the foot pedal has only been
tapped once, nothing will happen. The
device can be started again at any time.

MIDI Clock is a so called real­time message, which is sent 24
times per quarter note (MIDI
Time Code has to do with time
information and has nothing to
do with MIDI Clock). The in­structions of your keyboard or
sequencer will explain the use
of MIDI Clock for synchroniza­tion with your device.

INSTRUCTION MANUAL

Turning off

To turn ONE.2 off, double-click the pedal at more than 240bpm, or more
than twice the speed of its current tempo.

Turning on and starting

Tap the pedal on the “1” and the “2” (of course, you can also tap the “3”,
“4” (assuming 4/4 time) and the next “1” to get a more accurate result).
ONE.2 now transmits a continuous MIDI Clock signal and - if “phase correc­tion” is switched on - on the following “1”, a “MIDI Start” command is also
transmitted. This will start a connected sequencer. Accordingly, the ONE.2
will transmit a “MIDI Stop” when you turn it off.

While ONE.2 is running you can keep tapping at any time. This tapping inu­ences the tempo and, if “phase correction” is turned on, the phase. ONE.2
calculates the tempo with the average values of the last four time measure­ments. New values will only be accepted when they are at least half of the
actual tempo. Therefore, for larger tempo changes you should change the
tempo in small steps.

For arpeggiators, you may want to switch “phase
correction” off, because you typically start the
arpeggiator by pressing keyboard-keys.

If “phase correction” is on, each tap has an in-

uence on the phase and shifts the rhythm in

the direction of the next quarter note.

When the
music is completely off beat, the most exact
tempo is not useful.

For four new measure­ments you will have

to tap ve times: e.g.

“1” ­measurement - “2” ­measurement - “3” ­measurement - “4” ­measurement - “1”.

Tap-on function

This is why the ONE.2 uses a sophisticated algorithm, which will slightly
increase or decrease the tempo in a short time, to get constantly closer
to the time you are tapping.

phase correction „off“

(up)

To keep the inuence of inaccurate taps small,

the average values are constantly calculated. This
means that with an increasing amount of taps the

inuence on the phase is larger. When you stop

tapping, the phase shift ceases. However, single

taps still have a certain inuence.

Keep in mind that ONE.2
is an instrument and
exact tapping has to be
learned in the same way
that correct timing has to
be learned when play­ing other instruments.

Technical data:

• MIDI Clock from second tap on the foot switch

• If “phase correction” is on: MIDI Start on the rst “1”
(after 96 clocks), MIDI Stop when turning off

• Tempo range: 35 – 210 bpm

• Calculation exactness: 24bit, +/- 2 microseconds

• Powered via a USB power supply or USB device connector
(keyboard or computer)

• The USB plug is only for power supply, there’s no further
USB MIDI functionality
