Doepfer

Dear All I am interest to buy a alnalogue 
sequencer. Is Doepfer 's sequencer Good? Any body had use the A. 
sys's 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 Doepfer and RS 
2000. At least it had 16 steps 
and MIDI. It it Good? Any had use it? Is it necessary for use the 
analogue sequencer or I can use the software midi sequencer to 
control the System?
