Re the buzzing, if it only happens on certain notes, that suggests some sort of volume resonance in the machine. Acoustically, resonances are caused by reflections of the waves inside the volume. The way to fix that is to change the conditions at the boundaries (to make them harder/softer, more rigid/less rigid, etc...) I had a similar problem with my Yamaha P250. Certain notes would cause this horrible ringing sound that just grated on my nerves. I found that simply loosening the screws holding the side that was ringing greatly reduced the problem (presumably it made the boundaries less rigid). Had that not worked I would have tried wedging some thin rubber dam in as shim to reduce the vibration. Now I'm quite happy with the sound. I don't know if this is something that might work with the casio or not, but I thought I'd mention it just in case. smile

It is not the wire or some other out of box things cause the vibration issue. I put my px 350 on the carpet, it still makes buzzing sound from the left speaker for the same notes.

It is quite related to temperature and humidy. In some rainy and cold weather, the buzzing note will shift downwards or disappear completely, but some higher key start to buzz the right speaker. But in sunny day, the left speaker start to buzz again.

I have returned my PX 350 two times and they finally admit the defect and don't bother any further return/

Does the key action on the p155 is better than Casio offerings? I am not using the internal sounds

Personally, I'd prefer the Casio action. But even if most of us here prefer one or the other, that doesn't tell you which you'll prefer. It's entirely a matter of personal opinion, you need to try both. That said, I can tell you that there are some technical advantages in using a Casio as a controller for an external piano sound... triple sensor, high resolution MIDI velocity sensing.

login: if you don't care about the internal sounds the best value choice is easily a casio px150, hands down. Otherwise the next logical choice price-wise would be a vpc1. I just don't see yamaha in the equation given those parameters.

Right, if it's *only*being used as a controller. the PX-150 is the Casio that gives you the best bang for buck. The PX-350 has the advantages of standard MIDI jacks (in case you want to directly control something that isn't a computer) and line input jacks (in case you want to hear the external sound playing through the board's own speakers). The PX-5S has the advantage of definable knobs and sliders which can come in handy depending on what you're controlling.

You also bring up a good point that the VPC1 is a great option as a controller, one that many people would choose over a Casio, despite it not having the technical advantages I mentioned, triple sensor or high resolution MIDI velocity. Which shows again that there's no substitute for just getting your hands on the things and playing them.

According to http://www.kawaius.com/main_links/digital/vpc-1/vpc-1.html the VPC1 has a triple sensor detection.

Whoops! Thanks for the correction! (I think I was thinking of the MP10.)

The problem is that the Casio is more expensive here than the Yamaha p105 by 100 Usd, so I was wondering if the next Yamaha model would offer better action.

Most people feel that the GH action of the P155 is better than the GHS action of the P105... but there are also some people who prefer the GHS. If you don't need internal speakers (and for use as a controller, you probably don't), you might be able to find the CP33 for less money than the P155, and it has the same action.
