25. _M_I_D_I__K_e_y_b_o_a_r_d__T_o_o_l
The MIDI Keyboard application (invoked from the command line
as _m_i_d_i_k_e_y_s) is a graphical user interface which displays a
three-dimensional piano keyboard. Using the mouse or
computer keyboard key shortcuts, you may play notes on this
piano, which functions as a MIDI controller. Midikeys sends
MIDI Note-On, Note-Off, and controller events, over the MIDI
interface selected in its MIDI->Interface menu. This
allows you to play the internal Software MIDI Synthesizer
_m_i_d_i_s_y_n_t_h(_1) without need for an external MIDI keyboard.
Midikeys can also monitor MIDI activity on any single MIDI
channel. If the menu item Options->MIDI Input Animation is
toggled, midikeys will automatically press and release its
keys that correspond to Note-Ons and Note-Offs received on
the selected channel.
The MIDI synthesizer and its related applications, including
this tool, are installed from the optional subsystem
_d_m_e_d_i_a__e_o_e._s_w._s_y_n_t_h. To enable General MIDI synthesis, it
is also necessary to install the subsystem
_d_m_e_d_i_a__e_o_e._d_a_t_a._s_y_n_t_h, which contains a full set of General
MIDI presets for the synthesizer.
See the _m_i_d_i_k_e_y_s(_1) and _m_i_d_i_s_y_n_t_h(_1) man pages for
additional information.
25.1 _B_u_g__F_i_x_e_s
+o Key-downs triggered by the mouse button are now
released correctly even if the mouse leaves the
midikeys window.
25.1.1 _K_n_o_w_n__P_r_o_b_l_e_m_s__a_n_d__W_o_r_k_a_r_o_u_n_d_s
+o If the mouse is moved slowly over the keyboard with the
left button depressed, certain key transitions will
generate an oscillation of key-up and key-down events
between the keys. This is usually not a problem under
normal usage.
+o Not all combinations of computer keyboard key shortcuts
may be played simultaneously, i.e., the number of
chords playable via the computer keyboard shortcuts is
limited. This is a computer keyboard hardware
limitation, and there is no workaround other than to

use an external MIDI keyboard.
