Why is the volume uneven among the strings on my Roland GR-55 Synthesizer?
If you notice that the volume is uneven among the strings on your Roland Synthesizer, check if the 'GK SENS' setting was adjusted correctly for each string. Also, make sure the GK pickup is attached correctly by referring to its manual. The Roland website provides 'GK-3/3B Installation Tips' with explanations and photos on how to attach the GK pickup.
Why can't I control parameters set with Assign as expected on my Roland Synthesizer?
If you are unable to control parameters set with Assign as expected on your Roland Synthesizer, ensure that the effects incorporating the parameters being controlled are turned on. If using MIDI, verify that both devices are set to the same MIDI channel and that the controller numbers (CC#) match.
Why are MIDI messages not being transmitted/received on my Roland GR-55 Synthesizer?
If MIDI messages are not being transmitted or received by your Roland Synthesizer, first, try replacing the MIDI cable to eliminate any shorts. Then, check the connection between the GR-55 and the external MIDI device. Also, ensure that both devices are set to the same MIDI channel. If transmitting from the GR-55, verify that the Program Change message transmission is ON and the controller number settings are correct.
What to do if the external sound module connected to the MIDI OUT connector does not sound on my Roland Synthesizer?
If the external sound module connected to the MIDI OUT connector of your Roland Synthesizer does not produce sound, ensure that the MIDI channels of the transmitting and receiving devices match. Also, check if the volume has been turned down using the volume control of the GK pickup or the expression pedal; if so, raise the controller or volume.
How to stop unwanted synthesizer sound when playing softly on my Roland GR-55 Synthesizer?
To reduce unwanted triggering when playing softly on your Roland Synthesizer, adjust the 'VELOCITY' setting under 'GK SETTING.' Increasing the LOW VELOCITY CUT value will make softly played notes less likely to produce sound.
What causes oscillation on my Roland GR-55 Synthesizer and how to fix it?
If oscillation occurs with your Roland Synthesizer, check the effect settings. A gain value or volume-related parameter might be set too high; try decreasing the value.
Why is the synthesizer sound inconsistent in volume on my Roland GR-55 Synthesizer?
Adjust the 'PLAY FEEL' parameter on your Roland Synthesizer. Setting 'PLAY FEEL' to '5' provides a completely fixed velocity and consistent sound regardless of your playing strength.
Why does the pitch not change smoothly on my Roland GR-55?
If the pitch does not change smoothly on your Roland Synthesizer, check the master parameter GTR-MIDI-CHROMATIC. If it's turned 'ON,' pitch bend data will not be output, and the pitch will change in semitone steps. Turn it 'OFF.'
Why can't I change parameters with pedals or buttons on my Roland GR-55?
When INTERNAL PEDAL or WAVE PEDAL is used for the assign source on your Roland Synthesizer, the effect parameters set as the assign targets change automatically. To change parameters with the knobs or PATCH/VALUE dial, first switch off Control Assign and cancel the INTERNAL PEDAL setting.
