First Implementation / Priority

  • main screen
  • midi in/out config
  • edit lines and cells
  • show events
  • track config
  • beats -> tempo mode

Idea

  • a CLI gui tool to inspect and edit smf files
  • if smf type 0: columns are MIDI channels
  • if smf type 1: columns are track/channel combinations
  • time is running top to bottom, may scroll while playing
  • menu on top
  • view switch / special F1-F9 keys on bottom (like midnight explorer)
  • also a player: configurable MIDI-out connectors
  • also a recorder: configurable MIDI-in connectors (that also let the MIDI pass through to outs)
  • also a metronome (for recording)
  • also a graphical MIDI keyboards
  • ability to show/hide tracks
  • can have "attached", non-editable and watched MIDI files that are not merged into the current MIDI file but played together and that can be merged and exported per command
  • position: beat.decimal part of beat
  • Comments column indicates, if there is a comment. that could be shown/edited via command shortcut or displayed while playing, comments are numbered by appearance, so they can by shown by number, they will be saved as text in a separate track
  • ENTER creates a new line, shift+ENTER removes a line
  • CTRL+left/right next/previous column
  • CTRL+up/down next/previous marker
  • CTRL+T new track-column
  • CTRL+P play from current position
  • tab/shift+tab push current cell and following cells down/up a bar while keeping the cursor in the cell
  • CTRL-tab/CTRL+shift+tab push current cell and following cells down/up to the next marker while keeping the cursor in the cell
  • ALT-tab/shift+alt+tab push current cell and following cells down/up a beat while keeping the cursor in the cell
  • CTRL-ALT-tab/shift+ctrl+alt+tab push current cell and following cells down/up half a beat while keeping the cursor in the cell
  • CTRL+shift+up/down move the line up or down while keeping the cursor in the line
  • CTRL+shift+left/right move the position of the line one beat forward/back
  • CTRL+Alt+left/right move the position of the line one half beat forward/back
  • CTRL+N create a new line on the next bar
  • CTRL+B create a new line on the next beat
  • CTRL+H create a new line on the next half beat
  • export of the selected column to muskel file
  • have swing and delay settings for a column
  • impossible actions (like pushing post the end) will be indicated by a short screen flash
  • simultaneous events in empty line below
  • allow sending sysex and other initialization MIDI to external gear on start
  • general configs for shortcuts per instruments (like drumnotes, program changes etc.)
  • ESC always gets you to the main screen
  • main screen can have 5 different views that show/hide different tracks and keep their cursor position independant from each other
  • CTRL+ESC hide current track from current view
  • ALT+right scroll one column to the right
  • ALT+left scroll one column to the left
  • ALT+down scroll one column-page (=all displayed columns) to the right
  • ALT+up scroll one column-page (=all displayed columns) to the left
  • when doing horizontal/column scrolling the columns Comment Mark Bar and Beat stay visible
  • a track may not have more than 10 characters and may only have ascii characters
  • comments and text are UTF-8
  • there can be one config per directory that is valid for all midi files within the directory
  • editing is only possible while not playing/recording, however keyboard play and midi through is always possible while editing
  • the currently selected line is highlighted while in editing mode
  • while playing / recording the current position line(s) are highlighted
  • ALT+S Solo current track (toggle)
  • ALT+M mute current track (toggle)
  • ALT+R record arm current track (toggle)
  • ALT+O edit options for current track
  • there is also a play line that is separate from the cursor; F1 plays/stops the play line. when stopping with F1 the play line is set to the beginning of the bar of the stopping position
  • SPACE plays/stops from the cursor line. when stopping, the play line is not affected. one could start playing with F1 and stopping with SPACE or vice versa
  • CTRL+SPACE sets the play line to the start of the bar of the cursor line
  • CTRL+F1 jumps the screen to the playline without moving the cursor.
  • ALT+F1 jumps the screen to the playline and sets the cursor to the playline while keeping it in the same column
  • import of a track from another midi file at the current cursor position inside the current track
  • Transpose selected notes
  • shift+arrow-keys select: grow-shrink per column (left/right) and line/position (up/down)
  • CTRL+ENTER: edit cell value (dialog) or simply write to override all
  • CTRL++/CTRL+- change value / velocity (notes) one step at a time
  • CTRL+ALT+/CTRL+ALT- change value / velocity (notes) ten steps at a time
  • CTRL+#/CTRL+b change note by halftone up/down and play the result via midi ouput port
  • CTRL+ALT+#/CTRL+ALT+b change note by octave up/down and play the result via midi ouput port
  • allow to show / edit notes/cc/program names via descriptive textshortcuts that are resoved on a per track basis; the syntax is 'shortcut/value' e.g. 'kick/106' (note) or 'chorus/90' (cc) or 'rockorgan' (program)
  • when importing midi have intelligence to detect track delay
  • allow beat-track to help retrofit tempo changes
