[. . . ] KURZWEIL 150 FOURIER SYNTHESIZER SOUND MODELING PROGRAM For the Kurzweil 150 FS and the Apple IIe Version 1. 0 User's Guide KMSI P/N: 91010701 Section I -- OVERVIEW This manual for Version 1 of the 150FS Sound Modeling Program comprises seven sections. They are as follows: OVERVIEW DEFINITION OF TERMS SETUP 150 FS FUNCTIONS DESCRIPTION OF SMP FEATURES a Sound File Manipulation b Define or Edit a Single Sound Model c Construct or Edit a Complete Voice VI SOUND MODELING EXAMPLES VII CONSTRAINTS TO THE SYSTEM The logical structure of the Sound Modeling Program is a menu tree. There are three options plus an exit option at the top level of the program - the level which appears on the screen when you start the program. Options are selected by pressing the numeric key which corresponds to the number of the option as indicated in the option menus. [. . . ] If the 150FS is in Omni mode, communications will take place regardless of the Sound Modeling Program's transmission channel. If the 150FS is in Multi mode, the system will work as long as some program has been assigned to the MIDI channel on the 150FS that matches the Sound Modeling Program's transmission channel. If the 150FS is in Poly mode, its channel assignment must match that of the Sound Modeling Program. Once you see the MIDI MODE display, you may use INCR or DECR to find Omni. This will be the easiest mode selection, since the 150FS will continue to produce sound even if you inadvertently change MIDI channels in the Sound Modeling Program. ENTER MIDI CHANNEL 0 EXIT (S) as always, brings you up to the next higher level. 2 GLOBAL PARMS (S) highlights the global parameters, the set of conditions common to the entire model. Note that the values given in this example refer to the default model created from the LOAD/SAVE MODEL option: K150 FS . S. M. P.

This name will appear in the 150FS display when the layer editor is selected. Assign a new Audit Voice Number in the same fashion as with NAME above. The Audit Voice Number appears as the Test Prog # in the display of the 150FS when the model is audited. 3 BASE FREQUENCY (F) enables you to register the lowest frequency for which the model is intended to be used. It is used primarily to set the basic frequency from which the frequencies of the relative partials in a model are calculated. This option calls up a dialog box: ENTER FREQUENCY IN HERTZ (16. 3 - 9999) OR OCTAVES (0 - 9. 25) (MIDDLE C = 4. 00) Type in a value and press RETURN to change the value of the base frequency. 4 HIGHEST FREQUENCY (F) sets the highest frequency for which the model is intended to be used. The base and highest frequency options are bookkeeping aids which specify the low and high limits within which the model sounds realistic. These limits are important if several models are linked together into a voice which covers a wide range of the audio spectrum. 5 SUSTAIN OPTION (S) generates a menu with the following options: 1 DIEOUT (F), 2 HOLD (F), and 0 EXIT (S). Selecting DIEOUT causes the entire model to play through to its end when a key is held. This should be used for models whose contours eventually decay to silence, such as a piano or plucked string sound. HOLD causes the model to play to its end, then continue sounding at the endpoint of the contours until the key is released. [. . . ] - Press 3 2 You've selected the option for changing breakpoints in the contour, and inserted one of these breakpoints. Use the cursor keys to position the crosshairs, and move, insert, or delete breakpoints using keys 1, 2, and 3. - Press 0 4 1 2 This selects the option for editing the cross section of the model, allowing you to alter the amplitude of the model at various frequencies. By pressing 2 above, you changed the amplitude at the frequency indicated by the vertical crosshair. [. . . ]
