K5synth

Hi, my name is paul, i'm from argentina. I've recently baught a K5 
synth so i'm iniciating inthis new world. I've downloaded the PDF 
manual you posted and i'm reading it. But i have a really big problem 
and i'm desperate. It turns out that the sounds that came preset with 
the synth are awfull. I've been trying to send patches with many 
different programs but must have been doing something wrong. The 
synth seems to be working properly. When i connect it MIDI and play 
it with cakewal it doesn't seem to have any problems. But apart from 
using it MIDI i would like to have some good sounds indepedently from 
the computer. I just want the synth to have a good piano, some 
strngs, maybe a hammond, the standard sounds so i can take it to play 
with my band without bringin the whole computer. I've tried with 
patchers like the SySex of cakewalk and i couldn do much. Then i 
tried with the kfeunf editor and it seemed to have a connection 
problem (i could recieve from the synth but i couldn't send). And 
finally i been triyn to execute the Doctor T's atari editor with the 
steem emulator and it just doesn't want to work.
So please i need someone to tell me what to do. I need to be rescued 
or i will freak out. The only thing i want is to have some standard 
sounds saved on my synth, that's it. If someone can explain me how to 
do it, i will be thankfull.

Thanks

Paul.
