New in version 4.5.7


1. The primary new feature is that use with macOS Sierra is now supported. 

2. The current version is released as Intel-only. Older versions that are universal binaries are still available on the website.

3. Minor adjustments were made to help texts and to the generator ADD-TO.


New in version 4.5.6


1. Some additions and changes were made regarding the use of spectra.

         a. The tool LIMIT-SPECTRUM was added. It can limit a spectrum read with READ-SPECTRUM-FILE to only include pitches within a given range. The result is a spectrum which can be used with various spectral tools and generators such as spectrum->pitch, spectrum->chord, etc.

         b. The SORT keyword for a number of spectral tools and generators was adjusted to allow sorting pitches in either ascending or descending order.  This effects SPECTRUM->PITCH, SPECTRUM->FREQ, SPECTRUM->CHORD, and SPECTRUM->WINDOW.

         c. Keyword NAME was added to SPECTRUM->RANGE. This allows the range to be returned as note names rather than note numbers.

         d. SPECTRUM->WINDOW was adjusted to also print peak numbers. This information could be useful when specifying chords with SPECTRUM->CHORD. Keyword RAW was also added. It limits the printed information to frequency and amplitude and does not print the Midi equivalents.


2. Popup-menus are available when the cursor is in a text edit box. 

         a. When the cursor is CTRL-clicked (or the right mouse button is pressed), a popup menu appears. If the text edit box is in a dialog for defining an object,  e.g. in a data section dialog, the selected input can be used to plot values, print values (in the style of For Example), and make a histogram.  This can be seen as a shortcut for using the Plot Other, Histogram Other, and For Example dialogs. Each time a menu item is selected, the selected input is evaluated again which could result in a different series of values. Possible options are defined in the dialogs for Plot Other, Histogram Other, and For Example.

         b. The popup menu also includes some editing commands (cut, copy, paste, etc.). 

         c. Help for the selected text can be found by choosing the appropriate item from the popup menu.

         d. The editing commands and help item may also be available with other dialogs.

         e. The operating system may add other menu items relating to Services selected in Keyboard System Preferences. These additional items are not related to the AC Toolbox.


3. A POPUP MENU was added for the 'Do It' button in the FOR EXAMPLE dialog. When the button is CTRL-clicked (or the right mouse button is pressed), a popup menu appears. The same values that were printed in an example window can be plotted or used to make a histogram. Some plotting options are available when the 'Options' button is selected.


4. The POPUP MENUs for the right buttons in the PLOT OTHER and HISTOGRAM OTHER dialogs were adjusted to use the same values that were plotted or used for a histogram when performing the actions selected from the popup menu. This is a departure from the behavior in 4.5.5 when just the input was used to make a histogram, etc. but not the actual calculated values.


5. POPUP MENUs are available for the titles RHYTHM, PITCH, and VELOCITY in a data section dialog and NOTES in a note section dialog. When one of those titles (on the left side of the dialog, not in the text box) are CTRL-clicked (or clicked with the right mouse button), the rhythm, pitch, or velocity values of the object are plotted or used for a histogram.  This can be seen as a shortcut for the Plot Section dialog or the Histogram Section dialog. The options selected in those dialogs effect what happens with the popup menus. This behavior is different than what is described in number 2 above which just uses the input to make new values to plot, etc. 


6. Generator JITTER was added. It provides a symmetrical, uniform random distribution around a given value. The range of deviation can change over time. In some cases, this generator may be more convenient to use than the SHAKE generator.


7. An optional multiplication factor was added to FROM-NUMBER. This makes it easier to do something for half the number of events and something else for the other half.


8. An option was added to print channel numbers as instrument numbers when printing a TEXT SCORE.



9. The shape of an exponential decay produced by LINE and LINE-SEGMENT was adjusted to have the same behavior as that produced by GENERATE-LINE and EXPONENTIAL-MOTION.


10. If an orchestra is chosen for CSOUND FILE OPTIONS using the 'Use Open Orc File' menu item, the file name is added to the list of recent orchestra files available in the popup menu via the 'Select' button.


11. If the AC Toolbox is opened by double-clicking an environment or example file, the file name is added to the list of recent environments or examples.


12. The number of values to be produced when making a histogram (Tool>Histogram>Other) is now stored in the preferences and set when the AC Toolbox is loaded.


13. A general information text was added about popup menus. It can be found in the Index dialog.


14. The behavior of the menu item Help>Lookup Selection was slightly expanded. If an entire expression has been chosen, the first item is used when searching for help.
