[. . . ] If the adjustment times are unknown, simply go into the Change Points mode from the Edit Contours menu and use the Cursor Readout or Point Readout functions to find the times of the breakpoints of interest. For example, if you wish to adjust the amplitude of all even-order partials over the interval from 1. 0 second to 1. 7 seconds including any breakpoints at exactly 1. 0 or 1. 7 seconds, you should first select the even numbered partials and highlight SEL PAR. Then select the type of adjustment desired (explained below) and enter 999 for the beginning time and 1701 for the ending time. If 1000 and 1700 were entered instead, then breakpoints at exactly 1000 and 1700 would not be affected. The third parameter is the amount of adjustment in decibels. A positive adjustment means that breakpoints in the interval will be moved to higher amplitudes while a negative adjustment means that they will be moved to lower amplitudes. The adjustment range is restricted to 40 decibels either way, but you could simply adjust the same interval twice to get more range. The three adjustment options are STEP, RAMP UP, and RAMP DOWN. Step simply means that the specified adjustment amount is added to every breakpoint inside the interval. Ramp Up means that breakpoints near the beginning of the interval are adjusted very little while those near the end are adjusted nearly as much as the adjust amount. Those halfway into the interval are adjusted half the adjustment amount. Ramp Down simply reverses this, giving full adjustment at the beginning and less adjustment near the end of the interval. To get a "bump" in the middle of the interval with little adjustment at both beginning and end, just split the interval in half and ramp up in the first half and ramp down in the second half. A "dip" is the same except the adjust amount would be negative. Before the adjustment is actually made, . S. M. P. will determine if any breakpoint will try to go beyond 0dB. If it will, you will be asked if clipping the offending breakpoints at 0dB (and thus loosing some of the contour's shape) is acceptable. If N is entered then the adjustment is canceled and no breakpoints are changed. Note that there is no explicit "unadjust" for the amplitudes. However you can restore the original amplitudes by simply performing the same adjustment using the opposite adjust amount provided no clipping was performed. Of course you should always save your model on disk before using any global function that has the potential to radically alter the model. 11. 0 TIME ADJUST FUNCTIONS Time Adjust is similar to Amplitude adjust except that it alters the time of breakpoints while leaving the amplitudes alone. It can be used to slow down or speed up portions or all of a sound or delay or advance certain "events" in the evolution of a sound's contours. [. . . ] For example, the Macintosh keyboard has fewer keys than an Apple IIe and recognition of held keys is somewhat different. Also since the emulation speed is substantially less than a real Apple IIe, delay loops and beep routines act differently and the capacity for the emulated program to keep up with input data (for example, a MIDI stream) is less. Accordingly, the II-In-A-Mac version of the Sound Modeling Program is somewhat different in operation from that described in the . S. M. P. Since there are no cursor or Apple keys on the Macintosh keyboard, movement of the block cursor is accomplished with the following keys (CAPS LOCK must be on): U = cursor up D = cursor down L = cursor left R = cursor right N = next screen (open-apple/down) P = previous screen (open-apple up) 2.
