"Sugar" : Expresseur improvisation, with Pianoteq & Kore

Improvise

First steps

  1. Connect a MIDI keyboard ( cf user's guide )
  2. Open the Expresseur
  3. Load a text( or image) file describing a list of chords (eg  fairy_chords.png)
  4. Select the improvisation MIDI-setting (menu Setting/MIDI-preset )
  5. Next chord on the computer keyboard with the ALT+O
  6. Improvise on the MIDI keyboard ( white keys = pitches in tune, black keys = additional pitches )

Create grid-chords

  1. Search any song with standard list of chords ( Internet, real-book, ... )
  2. Copy these chords in the text-editor of the Expresseur
  3. Add a dash at the beginning of each lyric line
  4. Add some information about the structure ( part-A, part-B, structure parts AABB )
  5. Save the text file

Follow the grid-chord in a traditional paper-score

  1. Save any traditional one-page score under PNG image-format, with the same name than the text file of the grid-chord.
  2. In Expresseur, open the PNG image file. The score-image and the text file with the chords are opened automatically.
  3. To link the chords and the picture : click on a text-chord, and highlight the position on the image with a click&drag, (repeat for each chord ).

The tool returns the pithches to play for each chord/scale ( chord itelf, pentatonic, diatonic, alteration, walking-bass, .. )

Advanced usage

In the menu Settings/Midi-keyboard config, it is possible to select the keys ( MIDI or computer keyboard ) which are used to play ( or move within ) the chords.

Basic functionalities are provided to play the chords. To extend or change the behavior ( other scales, legato, .. ), it it possible to edit the LUA scripts, or to add controlers in the menu edit/LUA settings

Change the sound rendering

Use the mixer to balance the tracks and set the instruments

Inside the mixer, you can tune  :

  • volume with the cursors
  • device to play the tracks ( a MIDI piano, an SF2 soundfont, ... )
  • the instruments selectd in the device ( list can be set in specificil files )
  • the tuning of teh instruments ( pan, ... ) 

Connect a piano, or use a specific device

Any MIDI keyboard can be used.

When a numeric-MIDI-piano is connected, it is possible to play the piano-sound of this piano ( select the right device in the mixer ).

For intensive use ( or specific issue linked to handicap ), it is possible to adapt MIDI devices ( pads, .. ), or to build ad-hoc MIDI devices
