Thanks! The "defects" of the Tyros are NOT present in the Roland G-70 or the Korg PA1. But there is a price to pay for this. As you all know the realism of the Yamaha Tyros sounds are quite good in comparison with other keyboards. This is much due to how the sounds were sampled and its DSP engine. A lot of the samples in the Tyros are pseudo stereo samples, that means they have been sampled in mono, copied the track and applied something like a pitch shifter/chorus/delay and then panned hard left and right. But they have also used the phase in combination with this to create the realism. This is very obvious when using a PAZ analyzer. This in turn creates the perception of an acoustic type of sound. While this might work good enough for live usage and sounds great when soloing instruments it is hard to get right on a recording, since layering these kinds of sounds easily create phasing issues or something called "big mono". Now, what you normally do with pseudo stereo samples on a recording is to throw away the wet channel and create your own stereo sound. This normally works great, that's however not the case with the Yamaha Tyros, because when you do there's little natural warmth and clearity left. Take for instance the kick drum or digital piano. While it blends in better in the mix it also dies. Actually it is quite flat sounding. When using keyboards on a recording the ideal sound is a stereo sample that in itself sounds natural.

If you are thinking about going for either a Yamaha Tyros or Roland G-70 and use it as the base foundation of your recorded material, the Roland G-70 WILL sound better! It is quiter and has a much much better low end. It is not as realistic sounding but it hasn't got the cheesyness of the Tyros and that's the key. This means you can use at least drums, bass, organ, accoustic piano with a much better result than with the Tyros! As you noticed I was giving examples of sounds that all are quite heavy rhythm element sounds. This is important to pay attention to since a good sounding rhythm element is much more important for a song than for instance the pad element. Going with the Roland G-70 will give you a clear low end which will give your sound a professional edge which is always nice to build something around. Compared to the Korg PA1 it is also better because the combination of rhythm and pad is better in the Roland, much better. The organ is better, the bass is better and the piano is better. The Roland G-70 probably has been the most professional sounding keyboard so far.
