When performing live, it will be nice to determine the output of the speakers independently from the output jacks that go to the PA. Some even disable the speakers, but it will be nice not to disable the speakers and simply determine its volume independently.

Of course Clif some samples of acoustic piano
are more realistic than others. And this is
an important point, how many octaves of the
samplepiano are realistic!

sk880user. I can't seem to understand what you mean cause you can adjust the levels through your PA MIXER. so I don't seem to understand why you should have a seperate output LEFT + RIGHT volum controler, becuae you simply don't need it.I always MUTE the keyboard speakers when I am playing LIVE I only use them at home when I am editing.

Here is the reason why:

1) Usually, the speakers are muted during live performance. That is the habit of professional musicians. But I disagree with the rest. I believe there is a value in the internal speakers of the keyboards during live performance.

2) Surely, the external volume can be controlled from a PA assuming that there is another person helping you with the PA. But what I do is I control subset of that volume from the keyboard. I believe it is very convenient and very important especially while I am performing like crazy and do not have time to worry about other instruments.

Once I performed in a Church that had a digital piano by Roland. Similar to Yamaha P200 (portable with speakers). There was separate volume slider just for the speakers. That was wonderful! It made life so much easy.

sk880 <> As I always say everyone has his own needs, but in my case I don't see that is an issue, Firstly I am a singer so if I have my keyboard speakers on I will surely get a feedback from it especially when I go upbeat. I don't have a second person to set my PA, I manage to do that myself, but then again I have a Spirit Folio Power Amped Mixer so all the sliders are very easy to handle. So every one adapt to his or her setup. But honestly I never had any problem with setting the left and right chanels while I am performing live.
