Left mouse down over a key starts a note, left up stops it. The notes are also mapped to the computer keyboard keys, assuming an American English PC keyboard (sorry everyone else, but I don't know if I can map to absolute key position instead of value.) The white keys are on the second row, TAB to BACKSLASH, starting with note F3. The black keys map to the top row, '1' to BACKSPACE, starting with F#3. 'r' is middle C. Close the window or press ESCAPE to quit the program. Key velocity (note amplitude) varies vertically on the keyboard image, with minimum velocity at the top of a key and maximum velocity at bottom. Default Midi output, no device_id given, is to the default output device for the computer. 5Nzusing output_id :rr)Fmake_key_mappingrZK_TABZK_1ZK_qZK_2ZK_wZK_3ZK_eZK_rZK_5ZK_tZK_6ZK_yZK_uZK_8ZK_iZK_9ZK_oZK_0ZK_pZ K_LEFTBRACKETZK_EQUALSZK_RIGHTBRACKETZ K_BACKSPACEZ K_BACKSLASHrr r rZget_default_output_idrOutputZset_instrumentKeyboardr r!rectsizefillBACKGROUNDCOLORflipSurfaceget_sizedrawupdate map_regionsr"Z set_blockedZ MOUSEMOTIONsetwaitr$ZMOUSEBUTTONDOWNZget_atposkey_downZnote_onaddZ MOUSEBUTTONUPZnote_offkey_upremover%r&keyZK_ESCAPEKeyErrorZKEYUPr)r)Z CHURCH_ORGANZ instrument start_noten_notesZ key_mappingportZmidi_outkeyboardscreen background dirty_rectsregionsZ mouse_noteZon_notesr,velocity__noterrr output_mainXs+                            rRcCs*i}t|D] \}}||df||<q|S)zEReturn a dictionary of (note, velocity) by computer keyboard key code) enumerate)keysrGmappingrrErrrr1sr1c@s0eZdZdZddZddZddZdd Zd S) NullKeyzA dummy key that ignores events passed to it by other keys A NullKey instance is the left key instance used by default for the left most keyboard key. cCdSr rselfrrr_right_white_down zNullKey._right_white_downcCrXr rrYrrr_right_white_up r\zNullKey._right_white_upcCrXr rrYrrr_right_black_downr\zNullKey._right_black_downcCrXr rrYrrr_right_black_upr\zNullKey._right_black_upN)__name__ __module__ __qualname____doc__r[r]r^r_rrrrrWs  rWc@seZdZUdZeed<eed<eed<eed<ejed<e ed<e ed<e e ed <e ee eejffed <e ee eejffed <ejed <e ee eeejd fffed<e ee eeejd fffed<e ee eeejd fffed<e ee eeejd fffed<d S)KeyDataz8Used for passing in data to subclasses of the Key class. is_white_keyc_widthc_heightc_down_state_initialc_down_state_rect_initialc_notify_down_methodc_notify_up_method c_updates c_event_down c_event_up c_image_stripNc_event_right_white_downc_event_right_white_upc_event_right_black_downc_event_right_black_up)r`rarbrcbool__annotations__intrRectstrrrrr r9r rrrrrds"    """&rdc@steZdZUdZeed<dddZddZdd Zd d Z d d Z ddZ ddZ ddZ ddZddZddZdS)KeyaA key widget, maintains key state and draws the key's image Constructor arguments: ident - A unique key identifier. Any immutable type suitable as a key. posn - The location of the key on the display surface. key_left - Optional, the adjacent white key to the left. Changes in up and down state are propagated to that key. A key has an associated position and state. Related to state is the image drawn. State changes are managed with method calls, one method per event type. The up and down event methods are public. Other internal methods are for passing on state changes to the key_left key instance. key_dataNcCs|durt}t|d|d|jj|jj}||_|jj|_|jj |_ ||_ t ||_ t||jj|_t||jj|_||_t|j|jd|jjd|_|jj||jj|_dS)zzReturn a new Key instance The initial state is up, with all adjacent keys to the right also up.

This function automates the creation of a key widget class for the three basic key types. A key has two basic states, up or down ( depressed). Corresponding up and down images are drawn for each of these two states. But to give the illusion of depth, a key may have shadows cast upon it by the adjacent keys to its right. These shadows change depending on the up/down state of the key and its neighbors. So a key may support multiple images and states depending on the shadows. A key type is determined by the length of image_rects and the value of is_white. rrwhiteblackZ_right_Z_downZ_upNcs0eZdZe   ZdS)zkey_class..OurKeyN)r`rarbrdrzrrhrirmrrrsrprqrnrgrorjrkrlrfrerrOurKeySs$r)r5copylenry)ZupdatesZ image_striprreZdown_state_noneZdown_state_selfZdown_state_whiteZdown_state_self_whiteZdown_state_blackZdown_state_self_blackZdown_state_white_blackZdown_state_allZ key_colorrrrr key_classs(             0rreturnc Cstjtjtd}tj|dd}d}d}d}d}tj|}gd}i}t d D]} t | |d||||| <q,t d t |D]} t | |d||||| <qD||fS) aReturn a keyboard keys image strip and a mapping of image locations The return tuple is a pygame.Surface and a dictionary keyed by key name and valued by a pygame.Rect. This function encapsulates the constants relevant to the keyboard image file. There are five key types. One is the black key. The other four white keys are determined by the proximity of the black keys. The plain white key has no black key adjacent to it. A white-left and white-right key has a black key to the left or right of it respectively. A white-center key has a black key on both sides. A key may have up to six related images depending on the state of adjacent keys to its right. rdataz midikeys.png*^) black none black self white none white selfwhite self-whitewhite-left nonewhite-left selfwhite-left blackwhite-left self-blackwhite-left self-whitewhite-left allwhite-center nonewhite-center selfwhite-center blackwhite-center self-blackwhite-center self-whitewhite-center allwhite-right nonewhite-right selfwhite-right self-whiter) ospathsplitabspath__file__joinrimageloadrrwr) Zmy_dirZ strip_filewhite_key_widthwhite_key_heightblack_key_widthblack_key_heightstripnamesZrectsrrrr key_imagesis$    rc @s<eZdZUdZe\ZZedj\ZZ edj\Z Z e Z eeed<ee eededgdZee eedededgZee eed ed ed ed ed edgZee eededededededgZee eedededgZdedefddZd(ddZd d!Zd"d#Zd$d%Zd&d'ZdS))r3agMusical keyboard widget Constructor arguments: start_note: midi note value of the starting note on the keyboard. n_notes: number of notes (keys) on the keyboard.
