I will give studio to go a try sometime soon..The good news is, after 
much hullaballoo and numerous sessions of patch -p1, make menuconfigs.. 
with mistakes, endless sessions of booting to crippled kernel installs, 
liloconfig..liloconfig again (5 times in all) and interference from the 
much beloved artsd..I have managed to get a working slackware 
2.4.31kernel patched for lowlatency. I did discover that having the 
soundserver shut down completely in kde makes the war between jackd and 
artsd go away.  Now I only get the system timer warnings if the artsd is 
running when I start Rosegarden..so I guess the best setup for midi and 
audio recording in Rosegarden is to have that little twerp artsd turned off.
Having my kernel set to 1000hrz makes a big difference, the xruns have 
been cut to next to nothing.
I am finding Rosegarden 1.2.3 quite stable and am having good luck with 
everything except plug-ins...like reverb.
Considering the fact that gverb and all the other audio plugins sound 
like a tin can orchestra in Audacity I do not think I am missing very 
much :-)

Thank you Micheal for all your help!
