Welcome to Impro-Visor (Improvisation Advisor) Version 5.15, from Prof. Bob Keller at Harvey Mudd College, 2 May 2012. Release notes for this version may be found at the end. If you need help, please post to the Yahoo! impro-visor user group: http://launch.groups.yahoo.com/group/impro-visor/ From the group, you may also obtain The Imaginary Book which contains a large number of chords-only leadsheets, as well as other useful resources. Impro-Visor is free and runs on any platform that supports Java 1.6 or later, including: Windows (XP, 2000, Vista, 7) MacOSX (Snow Leopard 10.6 or later needed for Java 1.6) Linux The official information site for Impro-Visor is: http://www.cs.hmc.edu/~keller/jazz/improvisor which is the same as http://www.impro-visor.com The official download site for Impro-Visor is sourceForge: http://sourceforge.net/projects/impro-visor/ Download the installer that is provided for your platform, then launch the installer. Once the program is installed, there should be a launcher Impro-Visor that will run the program itself. The first time the program is run it will set up a folder in your user home for your personal version of various files. On Windows, you will need to adjust MIDI settings to get sound on your particular system. The Impro-Visor MIDI control panel is identified by a black circular icon (representing a MIDI connector) on the right side of the upper icon bar. Set it to one of: Microsoft GS Wavetable SW Synth Microsoft MIDI Mapper or some external synth. Alternatively, you may run by double-clicking the file: improvisor.jar which is a Java archive. You cannot start the application by clicking on individual leadsheet files. They must be opened from within. You can download the latest version of Java free from: http://www.java.com/download/ What you want is the JRE (Java Runtime Environment). I am pleased to acknowledge contributions from the following developers: Stephen Jones, Aaron Wolin David Morrison, Martin Hunt, Steven Gomez Jim Herold, Brandy McMenamy, Sayuri Soejima Emma Carlson, Jon Gillick, Kevin Tang, Stephen Lee Chad Waters, John Goodman, Lasconic, Ryan Wieghard, Amos Byon, Zack Merritt, Xanda Schofield, August Toman-Yih We hope you enjoy using the program. Sincerely, Bob Keller, Impro-Visor Project Director Professor of Computer Science Harvey Mudd College Claremont, CA 91711 keller@cs.hmc.edu =============================================================================== Release notes for Impro-Visor 5.15 Improves handling of MIDI track importing. Improves style extraction from MIDI capabilities. =============================================================================== Release notes for Impro-Visor 5.14 (pre-release) Bug fix: Fixes MusicXML export that was broken in 5.12, 5.13. Adds preliminary MIDI file import. Now a MIDI file can be loaded and played as such. Single tracks can be imported as Impro-Visor melodies. (We do not import an entire leadsheet with chord symbols, etc.) Sysex events in the MIDI file are ignored. Improves Style Extraction editor and repairs some long standing problems in that area. Replaces Generate button with Improvise toggle button. Now improvisation will continue until the button is toggled a second time. Playback stop is still through the stop button or the K key. =============================================================================== Release notes for Impro-Visor 5.13 Bug fix: Selecting New Leadsheet (control-N) caused the program to hang. =============================================================================== Release notes for Impro-Visor 5.12 Added volume specification options to style specifications. (Use Vnnn where nnn is an integer between 0 and 127 to control volume in notes following this term, up to the next V setting.) Changed Style Editor and Piano Roll Editor to accommodate volumes. Changed the layout of the Piano Roll Editor so that controls are at the top. Now the percussion instrument names can be names rather than numbers as before. Numbers are still accepted, but when style files are written, names will be used. Now MIDI channels can be assigned (in the Mixer panel), rather than be confined to fixed settings (melody = 1, chords = 4, bass = 7, drums = 10). Now there is an option to send MIDI Bank 0 Select before notes. This is set in the MIDI Preferences panel. Now each percussion instrument is assigned a separate MIDI track. This can be useful if the MIDI output is used as input to a Digital Audio Workstation, for example. Updated style files to use names for percussion instruments, added some volume settings, and removed some redundant or unwanted patterns. Fixed a problem in rendering bass lines, which was causing the bass instrument to move out of range. Fixed a problem with saving styles containing weights with decimal points which would cause them to fail to load. =============================================================================== Release notes for Impro-Visor 5.11 Fixes a bug that prevented roadmaps from opening. =============================================================================== Release notes for Impro-Visor 5.10 ------------------------------------------------------------------------------- The Style Editor workings have been greatly improved. Looping now works without having to set an inter-loop delay. Copying and pasting of large groups of cells is silent, as is creation of a pianoroll. ------------------------------------------------------------------------------- The shortcut for creating a pianoroll for a column is now control-shift-click, rather than shift-click as before. (Shift-click is used to extend a multi-cell selection.) ------------------------------------------------------------------------------- A bug was fixed in style rendering for playback. It only arose in certain styles, such as una-mas and senor-blues. ------------------------------------------------------------------------------- A bug was fixed wherein MIDI input entered during count-in would cause the program to lock up. ------------------------------------------------------------------------------- There is a remaining problem with MIDI input. If used for a long time, memory will fill up and the program will start slowing down and eventually need to be restarted. Usually this won't happen until after a couple of choruses have been entered. The problem is being worked. =============================================================================== Release notes for Impro-Visor 5.09 (pre-release for 5.10) ------------------------------------------------------------------------------- Windows users: You may need to set your MIDI settings (identified by the black circular icon) in Impro-Visor the first time you use this release. Use Microsoft GS Wavetable SW Synth if not using other MIDI devices. Use Microsoft MIDI Mapper if using other MIDI devices. The setting Java Sound Synthesizer might not work. Impro-Visor should remember your setting the next time you launch. ------------------------------------------------------------------------------- Added a new "push" element to style specifications, so that a chord can be struck before it appears in the leadsheet. The swing style is the only one currently using this feature. The former swing style has been renamed swing-square-comp. ------------------------------------------------------------------------------- The Section and Style Settings have been reworked. Now a style for any section other than the first can be specified as "Use style of previous section". It will appear as an asterisk in the style position. The point of this feature is that the style of an entire leadsheet can be changed without changing the styles of each section individually. This is important for roadmaps, since they will tend to use more sections to indicate harmonic phrasing. ------------------------------------------------------------------------------- Some problems with MIDI selection have been worked out. It is believed that changing MIDI instruments will no longer wedge the program. NOTE: Any MIDI instruments used must be in place and running before launching Impro-Visor. This includes software and hardware instruments. ------------------------------------------------------------------------------- Preference settings have been changed to 1-click. Icons for the various preferences are found at the right end of the icon tool bar. They are, left to right: Global settings (a picture of the Earth globe) Leadsheet settings (a leadsheet image) Chorus settings(a treble clef and time signature) Style and section settings (stylized note symbols) MIDI settings (a MIDI connector cross-section) Contour drawing settings (a pencil) Except for MIDI, these are the same icons as in previous versions. Once the preference window is opened, the icons inside can be used to select the various types of preference, as before. ------------------------------------------------------------------------------- In the Roadmap window, the option of selecting play-on-click. This means that clicking a brick will immediately play that brick. ------------------------------------------------------------------------------- The number of measures per line for roadmaps is now saved with the leadsheet. The default is 8. Currently this number can only be set by starting with a roadmap and creating a leadsheet, or by editing the text of the leadsheet using the textual editor (or an external editor). ------------------------------------------------------------------------------- The small status indicator in the tool bar has been replaced with text having green background in the uppermost menu-bar. Some improvements have been made in the information conveyed by the status indicator. ------------------------------------------------------------------------------- The button for toggling note beaming has been replaced with a checkbox in the View Menu. ------------------------------------------------------------------------------- A Recur button and Lead Beats spinner have been added next the Generate button. We are gradually moving toward the ability to have Impro-Visor generate choruses indefinitely. Currently this works by generating the next chorus just before the current chorus ends. The default setting is 1.05 beats before. This setting is touchy, in that if it is not just right, the next chorus will start too early or too late. The amount of beats required will depend on the tempo and the complexity of the generating grammar. ------------------------------------------------------------------------------- When a selection or chorus is being played, the slot construction lines are temporarily removed. The chord symbols are still shown in red. ------------------------------------------------------------------------------- A few new grammars have been added, including some for trading twos and eights, with either the computer first ("My") or the player first ("Your"). I also added a "Woody Shaw" grammar and a "Wes Montgomery" grammar derived from one each of their respective solos. Also, there is a Chord+Approach grammar that yields more "inside" melodies, as it does not introduce color tones intentionally. ------------------------------------------------------------------------------- Impro-Visor will now remember the last grammar used, and re-open with that grammar. ------------------------------------------------------------------------------- Impro-Visor will now remember the last style edited, and re-open the style editor with that style. ------------------------------------------------------------------------------- Fixed a bug in interpreting the textual leadsheet notation, wherein multiple dots on a note were wrongly interpreted. For example c2.. is now equivalent to c2+4+8 ------------------------------------------------------------------------------- Fixed a bug in the style editor wherein the checkboxes were being ignored. (The checkboxes are an indication not to save the instruments of those rows.) ------------------------------------------------------------------------------- Fixed a bug in the lick generator wherein parameters of the grammar, such as pitch range, were not being set unless the lick generator control panel is opened. ------------------------------------------------------------------------------- The recovery from a bad leadsheet file is somewhat improved. It is possible to escape the endless cycle caused by restarting with a bad leadsheet. ------------------------------------------------------------------------------- The number of bars per line was increased from 15 to 64. ------------------------------------------------------------------------------- The keyboard display, if used, now continues to update after the first chorus. ------------------------------------------------------------------------------- End of release notes for Impro-Visor 5.09 -------------------------------------------------------------------------------
