Unstable Pitch
Performance/Part Settings
•Is an aftertouch control source (CAT or PAT) assigned to a pitch-related control destination?
•Is an Fseq set to control pitch (EDIT [PERFORM]-COMMON-FSeq-Pitch=fseq)?
•Is the Note Shift parameter set to an appropriate value?
Voice Settings
•Are the pitch envelope generator parameters set properly?
•Are the frequency envelope parameters set properly?
•Are all pitch-related operator parameters set properly?
•Are you using LFO1 to apply pitch modulation?
•Are the operator frequency parameters (F.Coarse and Freq Fine) set to appropriate values?
Can't Select or Control Voices via MIDI
Program Change Reception
•Are the performance channel, part channel, and program mode parameters all set properly?
•Is there a problem with the bank select setting?
•Is there a problem with the program change reception setting?
•Are you attempting to receive program change data while in a mode other than the PLAY mode? Bank select and
program change data are only received in the PLAY mode.
Voice Control
•Is there a problem with the control change receive settings?
•Are your control source and destination settings made properly?
•Is there a problem with a velocity sensitivity setting?
•If using an Fseq to produce timbral variation, is the Fseq Switch parameter "on" and the Form parameter set to
"frmt" for the voiced operators used in the voice?
System Exclusive
•Is the FS1R device number set properly?
•Is there a problem with the system exclusive reception setting?
Voice Changes Too Drastically
Voice Control
•Is your source controller directly controlling the destination parameter?
•Is your source controller assigned to multiple destinations?
•Is an insertion effect assigned as a control destination (EDIT [PERFORM] mode COMMON/CtrlDst/VC1 ... VC8)?
Voice Settings
•Is an unvoiced operator bandwidth (EDIT [VOICE]-OPERATOR-Band Width) parameter set to "0"? This can cause
the unvoiced operator output level to become unstable (regardless of the EDIT [VOICE]-OPERATOR-Output Level
setting), with the effect that the sound changes drastically.
•When the Form parameter of a voiced operator is set to a value other than "sine", the settings of other parameters
can result in DC components and/or aliasing which can appear as noise. This is not a problem with the FS1R.
Can't Save a Voice
System Settings
•Is the Memory Allocation set properly?
