Why is there no sound from my Yamaha PSR-270 or connected MIDI device?
If there is no sound on either the PortaTone or the connected MIDI device, If Local Control (Function #84, page 97) is set to “off,” the PortaTone voices will not sound even when playing the keyboard. If Keyboard Out (Function #82, page 97) is set to “off,” the connected MIDI device will not sound when playing the PortaTone keyboard.
Why does my Yamaha PSR-270 Electronic Keyboard make noise when I use my mobile phone?
If you hear noise when using a mobile phone near your Yamaha Electronic Keyboard, it's likely due to interference. To fix this, either turn off your mobile phone or move it further away from the keyboard.
Why is my Yamaha PSR-270 Electronic Keyboard making a strange sound with a sequencer?
If you're using a sequencer with your Yamaha Electronic Keyboard and hear a strange “flanging” or “doubling” sound, and you are routing the MIDI OUT on sequencer and back to the MIDI IN, you may want to set Local Control to “off” to avoid MIDI “feedback.” When using the PortaTone with a sequencer, set MIDI Echo (or the relevant control) to “off.”
How to adjust voice volume on Yamaha PSR-270 Electronic Keyboard?
If the selected voice on your Yamaha Electronic Keyboard doesn't sound right or the volume is too low, ensure that the Main Voice Volume (#01, page 31), Dual Voice Volume (#11, page 35), and Split Voice Volume (#21, page 37) settings are properly adjusted.
How to fix accompaniment sound on Yamaha Electronic Keyboard?
If the accompaniment in your Yamaha Electronic Keyboard doesn't sound properly, make sure that the Accompaniment Volume (page 55) and Accompaniment Split Point (#51, page 59) are set to appropriate levels.
Why is the footswitch working in reverse on my Yamaha PSR-270?
If the footswitch on your Yamaha Electronic Keyboard seems to produce the opposite effect, it means the polarity of the footswitch is reversed. Ensure that the footswitch plug is properly connected to the FOOT SWITCH jack before turning on the power.
How to troubleshoot Reverb/Chorus/DSP/Harmony effects on Yamaha Electronic Keyboard?
If the Reverb/Chorus/DSP/Harmony effects can't be heard properly on your Yamaha Electronic Keyboard, make sure the Send Level parameter for the effect (and the intended voice: Main, Dual, or Split) is set correctly. Also, ensure the corresponding effect is turned on, and for Harmony, check that Harmony Volume (#39, page 44) is appropriately set.
Why can't I hear the rhythm when playing Pianist styles on my Yamaha Electronic Keyboard?
This is normal. The Pianist styles have no drums or bass — only piano accompaniment. The accompaniment of the style can only be heard when accompaniment is set to ON and keys are played in the auto accompaniment section of the keyboard.
Why are some voices cut off on my Yamaha PSR-270?
If not all voices seem to sound or the sound is cut off on your Yamaha Electronic Keyboard, it could be due to polyphony limits. The PortaTone has a maximum of 32 notes. If using Dual or Split voice mode with a style or song playing, some notes might be omitted.
