i have tried the Genesys pro. The PA1X , Tyros, G70 but have yet to try the SD1. ?They are hard to find in the uk. I have also tried the PSR3000.The most impressive was the Korg. Yamaha let themselves down with the lack of sampler and non existent sequencer. I have already commented on the Genesys and the G70 and hurt some peoples feelings so i will not say any more on thse boards) . I need an all in one keyboard as i am not a full time musician. I have a demanding job, a gorgeous 5 year old daughter that is into everything and not a whole lot of space so i need an instrument that is portable , and an all in one solution.

The best i have heard so far is the Korg PA1X. I was a Technics player before and then a Yammie fan for years but that keyboard is outstanding in terms of sound quality but the price at least last year was also outstanding !I write and arrange music for various Gospel choirs in the UK using my Yamaha PSR8000 and i needed an instrument that could be used as both an arranger for live work and a studio board but also with the facility to sample. Its much easier to experiment with an arranger and work out grooves or try a vibe (style ) that the choir can get into then and there . Once i know how they react to the grooves its then easy to record that and give it to live musicians to work out their own part. It also makes remixing a song instantly possible as i can change the groove of a song at the touch of a button. I'm not a pro musician but i demand quality from my instrument.Especially for the prices they are sold for .
