Analogue systems

Dear sir

  I am just order a RS 8000. And I also interest to buy a alnalogue 
sequencer  with the RS 8000. Of course RS2000 is the best 
combination. But the RS 2000 seems very difficult to use. And it is 
not cheap for me. Any body had use the RS 2000? Is it difficult to 
use. Is it useful. Actually I know nothing about the analogue 
sequencer. And then I know that analogue solution had a Oberkorn. It 
seems more feature than RS 2000. At least it had 16 steps and MIDI. 
It it Good? Any had use it? Actually I had put the RS140 midi/cv 
convector in my system. Is it necessary for use the analogue 
sequencer or I can use the software midi sequencer to control the 
System?
