I am new to the forum but need desperate help regarding this and other digital keyboard pianos in general. I have a Steinway Grand but decided to purchased the ROLAND as a second instrument. I've viewed many keyboard videos on youtube.com and all seem to have a problem as I: specifically, the keys that are pressed are not the sounding notes they should be. For example: when I accompany the melodic line with the right hand, the left hand playing the underlying harmonics gets out of tune. Keys that should sound like a C or D or E, etc., start sounding like a D, E or F...etc.
I thought I was going crazy with this in that I have perfect pitch but when I went back to the Steinway, all the notes sounded as they should.
I hope this makes some sense.
I checked the Roland site and for the RP701 there is an update called version 1.03. It is a bug fix. It isn't a bug fix for your specific issue however since this is version 1.03 perhaps updates 1.01 and 1.02 might actually address your issue. I would contact Roland and see if version 1.03 also includes version 1.01 and 1.02 updates contained within it; if not you may want to have Roland point you to where versions 1.01 and 1.02 are stored; these version might address your issue. It also might be that no one has reported this issue yet; so I would definitely contact Roland and bring the issue up and see if they can look into it. Also, since the keyboard is only a few months old then it is still under warranty. If dissatisfied I would return the instrument for a refund and pick a model that doesn't have the issue. A piano should not be out of tune in the left hand when the right hand is playing notes. It is definitely a software issue; if they are not going to address the issue then return the unit for a refund.
One final thought: I checked page 25 of the manual and it speaks to stretch tuning:
Single Note Tuning (*) -50–0–+50 Adjusts the tuning of each individual key. For example, you can adjust the width of stretched tuning, which tunes the higher register slightly higher and the lower register slightly lower.
There is also a factory reset:
Reset Setting Resets the “Piano Tone Edit” settings of the selected tone to their factory settings.
I would do a factory reset, I'm thinking that the keyboard is not set to equal temperament, somehow stretch tuning or some other temperament has been activated. After doing the factory reset, check to see that the keyboard is set to Equal. If not, set it to equal. I'm thinking that this is your issue.
