USING CLOCKWORKS FOR MAC OS X WITH THE MIDI TIMEPIECE AV 13
THE PEDALS TAB
This section explains how you can use the four knobs on the front
panel of the MIDI Timepiece AV and the two pedal inputs (A & B)
to:
■ Generate MIDI data, such as notes, controllers, patch changes,
pitch bend, and system exclusive
■ Route the data from the knob or pedal to any MIDI Timepiece
destination
■ Convert an audio tempo source such as an audio click into
MIDI data in order to slave MIDI hardware or software to the
audio tempo source
This document explains how to do these things with ClockWorks.
To l e a r n h ow to pro g ram the knobs and pedal from the front
panel LCD, see chapter 17, “Using the Front Panel LCD” in the
MOTU USB MIDI User’s Guide.
Choosing a pedal or knob to program
The first thing you need to do is select which knob or pedal you
are going to program.
1 Launch ClockWorks.
2 If you have more than one MIDI Timepiece, open the Device
List window from the File menu and select the unit you want to
program.
3 Click the Pedals & Knobs tab.
4 Choose the pedal or knob that you want to set up from the
menus at the top of the tab, as shown below in Figure 19:
Figure 19: The Pedals tab lets you program the MIDI Timepiece AV’s front-panel knobs
and its two pedal inputs.
Setting up a knob
To s e t up a knob:
1 Set the steps per click option.
This option determines the value change of the controller, sysex,
or patch change messages that are sent every time you turn the
knob one click. Normally, the value will change by one. Yo u c o uld,
however, get a more dramatic change with each click of the knob
by making this value five, for example. Then the knob will
generate values of 0, 5, 10, 15, 20, 25, etc. on each click.
2 Set the default value.
The value must be between zero and 127. When you first call up
the setup or modifier with this knob setting, the knobs will be set
to this initial value.
3 Enter a minimum and maximum value.
These values determine the lowest and highest value that the knob
can generate.
4 Select the type of data you wish to enter from the MIDI
Message menu.
A knob or pedal can generate MIDI notes, pitch bend, controller
data, sysex data, patch changes, and channel and polyphonic
aftertouch.
5 If you choose to send a controller, select the type of controller
you wish to generate.
6 If you chose system exclusive, see “Sending sysex data with a
knob” on page 15.
7 Choose the MIDI output cable and channel that you wish to
send the data to.
Setting up a pedal
To p ro g r a m t h e pedal inputs on the MIDI Timepiece AV:
1 Describe the type of pedal or input that is connected.
Yo u h a v e fi v e c h o i c e s s h o w n b e l o w in Figure 20. Roland and
KORG expression pedals are continuous control pedals, where the
MIDI Timepiece AV reads the position of the pedal and maps it to
a MIDI value between zero and 127. The foot switch setting
should be used for momentary foot pedals. If you choose the
click-to-MIDI option (which is only available on the Pedal A
input on the rear panel), skip the rest of the steps in this section
and see “Using an audio click as a tempo source” on page 15. For
Pedal B, you may also choose Alesis LRC for the pedal type.

2 follow the section below that applies to you.
