I have an A-190 which does all the basics very nicely. However, there 
are a few weirdies with it which I don't entirely understand.

1) Gate is NOT automatically patched into my A-143-2 quad ADSR. Is this 
because my A-190 is on the top rail and my A-143-2 is on the lower rail?

2) The LFO function seems to alter the amplitude of vibrato my mod 
wheel has on the note, and NOT the frequency as specified in the manual.

3) The clock-out seems to do nothing despite receiving clock signals 
from my sequencer (AFAIK). I was under the impression that it converted 
clock ticks from my sequencer's clock into gates, but the the 'clock' 
LED stays firmly unlit at all times regardless how much other sequenced 
information is sent. Is this normal? Have I misunderstood something? 
The only time I've had it light is when I patch a gate signal from 
another module (say, the A-143-2) IN to it!

4) There seems to be no way of enabling portamento without sending midi 
signals to the unit first - something my master keyboard does not do.

Overall, so far I'm tempted to 'downgrade' to the new midi unit when 
it's released!

Many thanks for any help. I've read all the manuals, and battled away 
with this for a month, but have - as yet - to gain any insight into 
what's going on.
