MT48DD 4 x 12 FloorPad Array
In this manual the individual Pads are referred to both as "Pads" and generically
as "Sensors". "Sensors" also includes the Joystick, Pedals and other hardware
that may be mentioned but may not be installed on your instrument.
The SENSOR controllers on-board the ZTAR encompass all of the performance
devices other than the fingerboard. Included are six Triggers for strumming and
picking and which have special setup software to tailor their operation. The
Triggers may be installed either as String Triggers, real strings that capture a
guitarist's picking techniques, or KeyTriggers, pressure- and velocity-sensing
bars that may be used to create new, expression techniques for controlling
synthesizers and other MIDI controlled devices. There is a wealth of controllable
features in modern synths that lies untapped and the various new touch-surfaces
of the Ztar attempt to open that door for you. There may also be installed on
your Ztar a bank of Expression Pads, usually 6 or 12 on most instruments. Two
pedal inputs, Sustain and Volume, are fully programmable. Any of the SENSOR
controllers may be assigned to control any two MIDI effects or Continuous
Controller assignments to four channels each. They may also be used to capture
and play back up to eight MIDI notes across one or more channels, control
external sequences and looped-samples, and other special functions.
The term "NOTE" is often used to refer to any MIDI event.
User Interface
We hope you enjoy this new user-interface and that you find the menu system
easy to navigate, considering the size of the display and the amount of
information that is available to be viewed and programmed.
The ZTAR is supported by a Programming/Display system with a 2 line by 40-
character backlit LCD and a 'softkey' based User Interface. What this means is
that the eight keys that surround the display are used in varying ways to select
different items depending on the particular menu screen showing. Where
necessary numeric values are scrolled up and down using the Up and Down
arrow (^ v) keys or the joystick. Most menus are entered with the softkeys.
The menu-system is a tree-like structure. The Ztar has quite a few programmable
parameters but every effort has been made to keep the nesting of menus to a
minimum and the navigation of the system as simple as possible.
The EDIT key is used both to enter an edit-screen in some menus and more often
to exit from a menu-screen when you're finished programming. In general, pressing

  • Page 2 EDIT several times will back you out of a series of menus and bring you back to the top-level LIVE-mode screen. The Ztar Operating System has a LIVE mode and an EDIT mode. Pressing the EDIT key from the LIVE-MENU enters the top-level SONG-EDIT screen to alter the various setup parameters of the fingerboard, pads, triggers, joystick and pedals.
  • Page 3 design new hardware. The WRITE and PANIC keys are still useful and the PAT+ and PAT- keys can be used to change patches for the selected channel. OCT Up/Down: These buttons allow you to change the Octave for any Zone on the fingerboard giving you access to the full MIDI note range.

(See the TIMING menu for this.) You’ll still need to set the fingerboard’s active zones’ Trigger-mode to TRIGGERS-ON to set up the Ztar as a guitar.

  • Page 16 The velocity-source may be set to follow the touch, position, or pressure of the Sensor by setting the screen-value to “PAD” or you may assign a Fixed velocity- or data-value for this Note by assigning a number.
  • Page 17 Gate: This sets the programmed note-duration. Press softkey#8 to toggle time between “absolute” (milliseconds) and “scaled” (MIDI clocks). MIDI clocks are displayed as nnn#, range 0-999. These events will play out according to the Tsig and BPM (if INT clock is selected), or the external MIDI clock (if A or B is selected).

By setting the velocity-ranges for the various events assigned to a pad, several unique effects or pad-modes can be created.
  • Page 20 hit will play event #1, a slightly harder hit will add Event#2, a somewhat harder hit event#3, and so on. This is an interesting way to build up chords with velocity. Vel=PAD This is a handy shortcut that sets all of a Pad’s events to track the Pad’s hit- velocity rather than output a fixed value.

NtsShft: [Shift Notes] When a single note is assigned to a Sensor, it’s pitch, or MIDI note-number, may be changed by varying the velocity, or force of your touch.
  • Page 22 ALTERNATING MODES The pad’s programmed events are played back one by one on each successive hit. These modes will operate on either the fixed 8-event buffer or the variable- length MIDISequence buffer. The order of event–list playback is different depending on the AltMode selected. AltUp: (Alternating Up) Events are played starting with Event#1 stepping up to the highest numbered event.
  • Page 23 6) Strike the pad once to start recording. Strike it again to stop recording. The sequence is automatically stored. RecNxt – first press starts Record and increments the sequence number ‘n’. Second press stops the record & stores it. Undo - decrements the sequence number on the last pad that did a RecNxt. ReTrig: When a Sensor is set to ReTrig, striking it will re-trigger any notes that are fretted on the assigned String-number on the fingerboard.

  • Page 25 THE SEQUENCERS In discussing the sequencers we use the word “NOTE” to refer to any MIDI event whether it’s a note, Control Change, ProgramChange, any outgoing message. A Sensor or Pad must be set with its Sensor-Mode to “EVENTS” (Sensors menu) and its HIT-mode (Sensors>TIMING menu) set to TIMED in order for it to fire a sequence.

NOTE: The variable-length ‘live’ sequencer records everything that goes to the MIDI Out port. This means that if you’re recording while listening to an existing track, the original track will be recorded with your live performance onto the new track, an implicit overdub.
