MOTM

>>>>
i have one question though... what do the yellow leds indicate? or 
are they not leds? :)
<<<<

They indicate the current stage. Look at any step sequencer and they 
will have an LED indicator per stage, one of which is lit when a 
stage is selected. Most sequencers have a single row of pots, but 
when designing in a narrow MOTM format, the rows have to be broken in 
half and run vertically instead of the more conventional horizontal 
direction. So you need 4 LEDs to indicate the row, and 2 to indicate 
the column. Once you get out to an 8U panel though, you can run the 
rows the correct way.

one thing that confuses me about these sequencers is the function of 
the individual set and position outputs... are these gate and cv outs 
for each individual step? personally, i don't have near enough stuff 
to utilize such a feature. i think these outputs would make a great 
expander module for those who do, though.
<<<<

That's two questions <g>. A position output is just a gate associated 
with a certain stage, which is at logic high whenever that stage is 
selected. The Set jacks are inputs to each stage, not outputs. A 
logic high pulse on a Set input sets that stage to be active 
immediately. So by patching various POS outputs to SET inputs, you 
can make the sequencer run between an arbitrary set of stages. The 
position gate outputs can also be used to trigger envelope generators 
or random other chains of events once a particular stage is reached.
