USING CLOCKWORKS FOR MAC OS X WITH THE MIDI TIMEPIECE AV 16
exactly the same except for the value of the variable byte. It
changes in correspondence with the current position of the knob
on a scale between zero and 127.
This feature is ideal for creating smooth, real-time changes to
parameters on synthesizers and other MIDI devices.
The reason for the 27-byte limit is that a message larger than 27
bytes cannot be transmitted efficiently enough to be generated in
real time.
To p ro g r a m t h e sysex message:
1 Set up the knob as described in “Setting up a knob” on page 13.
Once you have selected system exclusive as the type of data, you’ll
see the sysex data entry text box at the bottom of the pane.
2 Click inside the sysex data entry box and type in the bytes
necessary.
The message can be up to 27 bytes long, including the F0 and F7
at the beginning and end of the message.
3 For the variable byte, type “xx”.
4 Choose the output cable from the menu.
Sending sysex data with a footswitch
A footswitch can be used to send sysex data, as shown below in
Figure 25:
Figure 25: Sending sysex with a footswitch.
To t y p e i n the sysex message, click inside the sysex data entry box
and type in the bytes necessary, including the F0 and F7 at the
beginning and end of the message. There is no variable byte (as
there is with knobs). The entire sysex message is transmitted
when the footswitch is pressed.
Custom Pedal Curves
Custom pedal curves can be created and saved within Modifiers
to allow the MTP AV’s Pedal inputs to react in a non-linear
manner to control voltage foot pedals. When Pedal A or B input is
assigned to be controlled by a KORG or Roland Expression-type
foot pedal, you can make a custom pedal curve for that pedal in
the Pedal Curves window.
To m a ke a c u s t om pedal curve:
1 From the MTP AV USB front panel LCD, select or create a
Modifier in which you wish to store the pedal curve.
To s ave a p edal curve, it must be part of a Modifier. Pedal curves
cannot be saved as part of Base Setup.
2 Click the Use Custom Curve Table check box (Figure 21 on
page 14) and click the Edit button.
The Pedal Curve window appears.
Figure 26: Pedal Curve Window.
3 Use the mouse to draw a new curve.
Shift-drag to draw a straight line. If you shift-drag past the upper
right-hand corner, the line will snap to a perfect diagonal
(default) position.
4 Save the Modifier.
The custom pedal curve is saved as part of the modifier.
