Wizardry and Things I found out the hard way:
To keep multiple oscillators tracking accurately, use the same length patch cord from the source to each oscillator. The small voltage drop difference in different length patch cords can throw tracking off.
I experienced a
strange oscillator bleed through that I thought was something I just
had to live with, but turned out to be fixable. With 1/4" cables
going from my UAP to my mixer and NOTHING patched, I would hear
the oscillators going very faintly, especially at the higher end of
the audio range. So any unpatched oscillators would be making
an unwelcome contribution unless I tuned them to sub-audio A call
to Rex fixed the trouble. Cutting, relocating, and resoldering
the ground wire on the 1/4" jacks changed the ground path. Apparently,
this wire was acting as an antenna and picking up the radiated audio
frequency energy from the oscillators. If you're ordering a system,
tell Rex about any grounding considerations; that way he can take care
of this before shipping. If you have this problem, call Rex before
cutting any wires!
Blue, and Gold
Sound Transform Systems has a couple of prepackaged systems called the Red Fun Station and the Blue Fun Station (as opposed to 'work station'). These are three-panel synthesizer systems with a configuration that's as close to being 'stock' as Serges ever get. In many cases Sound Transform Systems will work with you on designing panels laid out with modules that you choose, but since each panel is custom made, this process takes several weeks. If the module complement in a Red or Blue fun station will do the trick for you, Rex Probe keeps a stock of those handy, speeding up the process.
The Fun Station configurations include a few oscillators, the UAP, a sequencer or two, filter, DTG's and USG's, Random Source, and a few other modules to make things interesting
The Gold Book
The stage select trigger outputs of the TKB stays high for as long as the stage is selected. Note that the TKB has stage trigger outputs, while the sequencer/programmers have stage select inputs. This means that as a stage goes active on the TKB, its stage select output goes high (it's an output). And on a sequencer/programmer, making a stage select trigger input go high will cause that stage to be selected (it's an input).
The trigger inputs
of the DSG and DTG initiate a full rise/fall cycle. Retriggering
before the cycle is done will not result in a new attack slope.
The module ignores the next trigger until the cycle is completely done.
There is a way to mimic attack retriggering on DSG, that is to feed
the pulse into the INPUT jack instead of the TRIG jack. So the
DSG is behaving as a slew generator, but the result is the same.
You have to be careful of the incoming voltage though, since any voltages
at the INPUT jack will also end up at the output (the DSG/DTG is a voltage
follower with variable slew rate). Also, if the pulse goes to
zero before the attack is complete, you won't get a full attack, just
that initial portion of it.
The Trigger output of the Random Source is a random on-off voltage that swings from 0 to 4.5v. Since the Random Source is basically a noise source connected to an SSG, the trigger output of the RS corresponds to the coupler on the SSG. Note that on the RS, the trigger voltage swing is only 4.5 v.
Eventually you want to have some way of combining triggers together. That's what the Boolean Logic module is for, (mostly). It would be nice if you could simply pile a set of trigger outputs on one input (I think the Buchlas could do this), but the electronics don't work that way; you can drive any number of inputs from one output, but don't drive one input from multiple outputs.
