Hello, Im singing in a piano bar in Hong Kong. We cannot do a sound check and try the best effect for voice. The equipment has a Yamaha spx2000 effects processor. Please, can you tell me what is the best Effect for female voice? It's a not so big place.My band is acoustic piano, drums and electric bass. Ill appreciate your help. Thank you so much! Kelly

try these?

Yes you may use it as stand alone piano. Usually everytime you will power ON any yamaha psr model piano will appear as default voice.

maybe this will help ...... I have a Korg M1 ..... it has a small button battery for maintaining memory and sounds .... mine lasted about 10 years ...... I looked up in Google how to change the battery .... I looked up in my M1 instructions how to reload the sounds .... I had lost all my synth sounds except the basic piano ...... I changed the battery and reloaded the sounds from a backup card I had bought years ago .... M1 works perfectly now .... you probably lost any saved songs .... contact Yamaha how to change the battery and reload the original songs .... any saved songs are gone .... next time, back them up ... good luck

• Performance assistance technology

I would check your fingering... You MAY be late in hitting a particular note and the using auto chord... this can cause the problem. Another thing is if notes are hit with different velocity that can affect the sound. Sometimes certain voices have VELOCITY switching which actually changes the voice depending on the velocity you hit a note.

All I can suggest is try a master reset. It could be a software bug or a dried out electrolytic capacitor in the power supply.

Some of the Yamaha pianos have several pianos emulated and selecting a "Grand" will sound different than if you select an "Electric" or "***** Tonk" setting.

There is NO internal adjustment for this. other than the voice selection. Choose either the Grand1 or Grand2. Do not use reverb as this can "ring".
