Analogue systems

Hey guys,

I recently acquired an RS-200 sequencer for my Analogue systems 
synth. 
With it came a sequential switch and Gated Delay. 

I dunno if any of you know these modules well, but it's worth a shot. 
I really can't figure out what to do with the Gate Delay. I've read 
the manual PDF, but it makes no sense in a musical meaning. It's one 
of those modules you'll never ever see on a non-modular synth, so 
it's new to me. 
It isn't a normal delay as you think of it, it's a delay that delays 
trigger and gate signals, not audio signals. 

What's the most useful application for this module? It has me kind of 
beat. 
I've heard the gate delay is nearly essential together with the step 
sequencer. I just don't see why. I'd like some examples of its use in 
a patch for instance.

Sequential switch is also a new concept to me, but I'm grasping it a 
little better at least. I can use it to extend the sequence to 24 
steps (all 3 rows), have it bounce back and forth between rows etc. I 
suppose I could use it to switch between different signal paths with 
a trigger clock pulse too. I've run audio rate frequency into it and 
swapped between 2 or 3 waveforms, creating interesting timbres.

What I'd like from this thread is some guidelines to how I can get 
the most out of these modules. I know they are common amongst many 
manufacturers as pure utility modules (not audio modules). Help me 
out, please  I feel like I have a solid grasp on the other modules 
(and subtractive synthesis), but these are new concepts to me. 
I've had keyboard synths for more than a decade, but modular is a new 
thing.

The rest of my system is currently: 

2 VCO's, EG, Multimode filter, Modulation controller (LFO, noise gen, 
S&H, small vca), VCA, frequency divider, step sequencer, gate delay, 
sequential switch. I think I'll swap the divider with a ringmod.
Had a standard System 3 system, but ripped out 50% of the modules to 
fit the huge sequencer until I can afford another RS15 case.

I've heard you can use a gate delay to creating arythmic changes in a 
sequence, create "swing" and groove. But I can't figure out how :P
