I have Powertracks Pro and Cakewalk Home Studio. I have not got into either of them yet, you guys seem to have already used them already.

Which ones seems to be eaiser or worth to learn?

Frank,
I have Power Tracks and Sonar....while PT is a good sequencing program in it's own right, Sonar has far more to offer as far as options in the program and what can be done with it in depth.

I have home studio 2002. I would go with that,since if you upgrade to Sonar, the interface is the same.
Also, if you can afford it, get home studioXL
since it has the DR008 drum machine sampler
Dxi plug-in. Great program for the money.
Powertracks is good if you don't want to
spend as much. But it makes more sense to
me to invest our precious time to go with
cakewalk.
