[. . . ] 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. [. . . ] 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. This is useful for models of sustained sounds such as an organ or wind instrument. 6 RELEASE OPTION (S) calls up another options menu: 1 FINISH (F), 2 TERMINATE (F), and 0 EXIT are the options. FINISH causes the entire model to play through to its end regardless of when the key is released. It is used with models of sounds such as undamped chimes. Selecting TERMINATE causes all of the contours in a model to begin their decay to silence as soon as the key is released. 7 LOUDNESS (F) highlights the Loudness field and calls up a dialog box: ENTER LOUDNESS IN dB, 95. 6 IS LOUDEST Type in a value and press RETURN to set the maximum loudness that the model can reach. 8 SLOW XOVER (F) (SLOW CROSSOVER) affects the conversion of data from internal Sound Modeling Program format to the 150FS format. Selecting a large value for this option causes the conversion to be very precise, but can lead to a soft "buzzing" noise in some cases when very low notes are played. Smaller values reduce this noise, but at the expense of some accuracy in playing the contours you have drawn. It is best to leave this option at its default value of 4 unless the noise is objectionable or you have completed the editing of your model. Pressing 8 at this level brings up the following dialog box: ENTER CROSSOVER FROM SMALL AMPLITUDE STEPS. (1 - 99) LARGER IS ACCURATE, SMALLER IS QUIET Type in a value and press RETURN to adjust crossover. 9 AUDIT (S) as described above, allows you to hear the effects of your editing. 3 PARTIAL PARMS(S) generates a display with the following features: PARTIAL PARMS 1 2 3 4 5 6 7 8 9 0 ADD OR DELETE TYPE INDIVIDUAL FREQUENCY P# F T HERTZ OCT MULT P# F T HERTZ OCT MULT RELEASE 1 R 261. 6 4. 00 1. 00 2 R 523. 2 5. 00 2. 00 AUDIT EXIT 1 ADD OR DELETE (S) highlights a partial and calls up a menu with the following options: 1 ADD (F), 2 DELETE (F), 9 AUDIT (S), and 0 EXIT (S). The up and down cursor keys may be used to select partials. Holding the up or down key will scroll rapidly through the partials after a delay of approximately a second. One page of the parameter list displays 32 partials in two columns of 16. The left and right cursor keys may be used to hop between columns. If your model contains more than 32 partials, you will not be able to display them all on one page. To flip between the pages of the parameter list, use the up and down cursor keys while holding the open apple key. [. . . ] This is a very large and complex model (the models which compose the 150FS's resident voices range in memory requirements from 200 to 500 bytes - 0. 5K). This limit is not checked by the program. Exceeding it is likely to cause the program to hang. When working with a very large model, occasionally check its size, which is displayed under the highlighted word "GLOBAL, " in the MODEL ATTRIBUTES display, which initially is called up by selecting the GLOBAL PARMS option.
