User manual YAMAHA SPX900

[. . . ] Individual two-band parametric EQ and dynamic filter parameters are provided for each effect program for precise tonal tailoring. In addition to the basic effect and EQ parameters, the SPX900 offers a list of "internal parameters" which provide exacting control over the effect sound. The SPX900 is also MIDI compatible, with a MIDI IN terminal that allows MIDI selection of effect programs, and a switchable MIDI THRU/OUT terminal. When switched to OUT, edited programs stored in internal RAM can be dumped to a MIDI data recorder or other data storage device. [. . . ] CHORUS) Sets the amount of the width of amplitude variation. MODULATION PROGRAMS 13. SYMPHONIC 18 PARAMETERS ACCESSED BY THE INT PARAM KEY High-pass Filter Frequency (HPF FRQ): THRU, 32 Hz ­ 1. 0 kHz Hold Time (HOLD): 1 ­ 24000 milliseconds Determines how long the gate stays open, allowing the signal to pass at the DECAY LEVEL, after the first decay and prior to beginning of the RELEASE TIME. Release Time (RELEASE): 3 ­ 24000 milliseconds Permits rolling off the low-frequency content of the reverb signal above the set frequency. The HPF is OFF when set to THRU. Determines how long it takes for the gate to close fully after the HOLD TIME has ended. Low-pass Filter Frequency (LPF FRQ): 1 ­ 16 kHz, THRU Analog Trigger Level (A. TRG LVL): 0 ­ 100% Permits rolling off the high-frequency content of the reverb signal above the set frequency. The LPF is OFF when set to THRU. NOISE GATE 19. ADR-NOISE GATE This program uses a "gate" to pass or shut off the input signal in a number of ways. It can be used to pass just a short segment of a longer input signal, or it can be set up to pass only signals that exceed a specified level. In the latter case this program functions as a "noise gate. " It is also possible to create reverse gate type effects in which the gain increases gradually after the effect is triggered. PARAMETERS ACCESSED BY THE PARAM KEY Trigger Level (TRG. LEVEL): 0 ­ 100% When an analog signal applied to the rear-panel TRIGGER 2 ANALOG jack is used to trigger the gate, this parameter determines the level of the input signal required to trigger "opening" of the gate. At 100% only very high-level input signals will trigger the gate, while at 1% even the tiniest input signal will trigger the gate. If a key more than two octaves higher or lower than the BASE KEY is pressed, the resultant pitch change setting will still be within the -24 to +24 range, as shown in the illustration below. If the BASE KEY parameter is set OFF, pitch cannot be controlled via the MIDI IN terminal. FREEZE PROGRAMS Pitch Shift (PITCH): -24 ­ +24 Set the pitch of the pitch-shifted note between two octaves below (-24) and two octaves above (+24) the input note. Fine Tuning (PITCH FINE): -100 ­ +100 23. STEREO FREEZE The FREEZE programs allow sampling (digital recording) and playback of sounds received at the SPX900's inputs. The FREEZE 1 and FREEZE 2 programs permit sampling for a maximum of 5. 8 seconds, while the STEREO FREEZE program allows sampling for a maximum of 2. 9 seconds. The FREEZE 1 and FREEZE 2 programs differ only in the playback functions provided. Permit fine tuning of the pitch-shifted note in l-cent steps. Delay Time (DELAY): 0. 1 ­ 2300 milliseconds Determine the time delay between input of the original note and output of the pitch-shifted note. Feedback Gain (FB GAIN): -99 ­ +99 When this parameter is set to 0, only a single pitch-shifted sound is produced after the DELAY time has elapsed. As the value of this parameter is increased, however, more and more delayed repeats are produced, each pitch-shifted up or down from the previous repeat according to the setting of the PITCH parameter. PARAMETERS ACCESSED BY THE PARAM KEY 23. FREEZE 1 The FREEZE 1 program allows single playback of the sampled sound, with adjustable start and end points. Record Mode (REC. MODE): MANUAL, AUTO Determines how sampling is to be triggered. If MANUAL is selected, sampling is initiated either by pressing the parameter key, the TRIGGER key, or a footswitch connected to the rear-panel TRIGGER 1 SW jack. If AUTO is selected, sampling is automatically triggered by any input signal of sufficient level. DLY): -5800 ­ +1000 milliseconds Overdub Ready (OVERDUB): This parameter sets a delay between triggering and actual initiation of the sampling process.
