Left Feedback Gain (L.F.B.): -99 - +99% Right Feedback Gain (R.F.B.): -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. L DLY PITCH L F.B. R DLY PITCH R F.B. • 30. PITCH CHANGE 3 PITCH CHANGE 3 offers the "thickest" and most complex sound by allowing the creation of three pitch-shifted notes in addition to the direct sound. 1st Pitch Shift (1PITCH): -24 - +24 2nd Pitch Shift (2 PITCH): -24 - +24 3rd Pitch Shift (3 PITCH): -24 - +24 Set the pitch of the first, second or third pitch-shifted note between two octaves below (-24) and two octaves above (+24) the input note. 1st Fine Tuning (1FINE): -100- +100 2nd Fine.Tuning (2 FINE): -100 - +100 3rd Fine Tuning (3 FINE): -100 - +100 Permit fine tuning of the first, second or third pitch-shifted note in 1-cent steps. 1st Delay Time (1DLY): 0.1 - 1400.0 milliseconds 2nd Delay Time (2 DLV): 0.1 - 1400.0 milliseconds 3rd Delay Time (3 DLV): 0.1 - 1400.0 milliseconds Determines the time delay between input of the original note and output of the first, second or third pitch-shifted note. 1st Level (1LEVEL): 0 - 100% 2nd Level (2 LEVEL): 0 - 100% 3rd Level (3 LEVEL): 0 - 100% These parameters determine the levels of the first, second and third pitch-shifted notes. 1 DLY PITCH 2 DLY PITCH 3 DLY PITCH • 31. MONO PITCH The MONO PITCH program produces a single pitch-shifted note. The PITCH parameter can be varied while playing (using an external controller, for example) to provide smooth, real-time pitch variation. DELAY PITCH 1 O° RL 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 Permit fine tuning of the pitch-shifted note in 1-cent steps. Delay Time (DELAY): 0.1 - 1400.0 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 INT PARAM KEY Base Key (BASE KEY): OFF, C1 - C6 This parameter sets the "BASE KEY" for an external MIDI synthesizer used to control the PITCH parameter (the MIDI OUT terminal of the synthesizer must be connected to the SPX900 MIDI IN terminal, and the SPX900 must be set to receive on the MIDI channel on which the synthesizer is transmitting). If, for example, the BASE KEY parameter is set to C4, pressing the C3 key on the synthesizer (C3 is one octave lower than C4) will set the pitch change value to -12. Pressing D4 on the keyboard would produce a pitch increase of one whole-tone (+2). When two keys are pressed, the highest note determines the pitch of the 1 PITCH or L PITCH sound, and the lower note determines the pitch of the 2 PITCH or R PITCH sound. With the STEREO PITCH program the last note pressed takes priority. 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, 18
