| The Keyboard Window
The Keyboard window enables the entry of musical information via the
use of its virtual keyboard or by typing directly on the computer
keyboard. It also allows pitch bend and modulation (MIDI controller
number 1) to be entered. Modulation can alternatively be entered via
the mouse wheel.
is a limit on most computer keyboards as to the number of detectable
keys at one time so you may be limited to certain combinations of keys
when trying to play chords.
The keys on the
computer keyboard are arranged for a more than 2 octave range. The
lower octave, corresponding to a standard piano keyboard, contains the
Note: the white keys occur all in a row.
The upper octave contains the keys:
Z,S,X,D,C,V,G,B,H,N,J,M, and the comma key. Some
extra notes occur past the end of the higher octave.
The '[' and ']' keys on the computer keyboard are
used to change the current octave.
keyboard window also houses the Real-Time Arpeggiator. The Real-Time
Arpeggiator features multiple arpeggiation patterns; multiple
arpeggiation methods; octaves control; sync control; swing control;
steps control; pattern UI area with 16 X 3 steps, each with quick
independent control over transpose, velocity and duration via popup;
latching; retriggering; initialize pattern; randomize pattern; shuffle
pattern; load and save presets; copy and paste; transpose up and down;
remote control of arp parameters; spread slider for guitar like
strumming; left and right arrow keys can be used to rotate the current
pattern; and more.
The Real-Time Arpeggiator works with
all soft synth plugs and external MIDI and is now available for Metro
SE and Metro LX users.

explanation of particular functions.
the 'real time arpeggiator on' switch to toggle the arppeggiator on and
options menu provides functionality for controlling the powerful
arpeggiator functions. Use 'Open Preset...' to load a preset from the
file system. Presets include all parameters and patterns. Use 'Save
Preset As..' to save a copy of the current arpeggiator settings.
'Initialize' sets all arpeggiator settings to
is a powerful function that creates a random pattern. It makes
intelligient decisions to try to produce more useful results.
'Randomize Rhythm' is the same as Randomize
accept that it does not affect pitch information.
'Shuffle' rearranges the current pattern by
shuffling the steps.
'Copy' copies the current pattern for use by the
pastes the current contents of the arpeggiator clipboard over the
current pattern. This function is only available if an arpeggiation
pattern had previously been copied and it is not undoable.
'Rotate Left' and 'Rotate Right' rotates the
current pattern in the direction specified.
'Transpose Up' and 'Transpose Down' transposes the
current pattern up or down one half step respectively.
Latch allows the arpeggiator to continue after the
keys come up.
keys pressed in the middle of pattern are synced based on the position
in the pattern and start in the middle. If Retrigger is checked, the
pattern will restart from the beginning regardless of the current
The method popup determines how the arpeggiation
Notes are sorted and processed from lowest to highest pitch and then
highest to lowest. The highest and lowest notes are only processed
UpDownEdges: Same as UpDown but the highest and
lowest notes are processed twice.
Up: Notes are processed from lowest to highest.
Down: Notes are processed from highes to lowest.
Chords: Notes are played at each step as they are
chords: Same as Chords except that transposed notes are tranposed in
the current scale based on the time signature of the section.
This setting determines the duration of each step
in the currently selected pattern.
Octaves setting within the arpeggiator section determines the number of
extra octaves added to the arpeggiator function. Octaves are always
added higher in pitch.
The Octaves setting outside of the
arpeggiator section determines what the first note of the onscreen
keyboard will be. You may also use the '[' and ']' keys on the computer
keyboard to change the current octaves setting.
This setting determines the number of steps in the
currently selected pattern.
setting determines the swing of the current pattern. Swing of 50% is no
swing. Otherwise swing affects the position of every other note in the
This setting causes notes in the pattern to be
spread out or flammed by the percent specified.

|'L' or '1' or lowest
||Plays the lowest pitch note.
|'H' or highest
||Plays the highest pitch note.
||Play the current position determined by the

the randomness setting applied. If mouse velocity is selected the
velocity will be based on the current horizontal position of the mouse
in the velocity region of the keyboard window.

the designated pitch and with the velocity specified.
