Dan, I'm sorry for the wall of text but I hope this answers you questions:
The oscillating preset is, and I don't mean this in a patronizing way, a preset. A mistake I did initially was to think that the preset was a different feature of the Neurocyte but in reality all it does is make the outputs, functions and settings of the Neurocity certain calculated values to produce a oscillation of outputs. But once you put the oscillation, the channel outputs and other stuff will be in a certain way and the mechanism is delicate; so the most easy policy is don't touch anything in the channel outputs of that if you plan to have the oscillation working.
The oscillation always is between two types of signals, you mentioned that you want to know how the preset manages the signals meaning how it produces oscillation (that what I understood of you question) and honesly I never went and look try to figure that out. This is one of those things where you won't need the why it works as long as you know how to use it. Petter (at least I think it was him) already figure it out for us
If the preset isn't producing the intented results, more often than you'd think the guilty past is the "Number of adhesin connections" option. Always remember to put that correctly for it will change the ouput values to match the signal diffusion that happens when more cells are present.
An explanation of each option in the preset can be found in the Neurocyte Wiki Page
so if you don't get the Channel Oscillation or Period options, there are some general explanations. If you need specifics, please ask more
If you're going to use straight channel settings then there's no much secret to it. Output Channel choses which signal will be, S1 S2 S3 or S4. This means that if the Neurocyte is producing S2 and a Flagellocyte connected to it uses a Channel Dependence of S3, it won't be affected by the neurocyte.
The Output slider sets a fixed value of output. This is used very rarely.
And of course, the hard part:
There's another Wiki Article
dedicated to this, so maybe that will help. If the explanation there is confusing at some point please say it so I can answer you and then go to the wiki and fix it so the next person doesn't get confused. For now I'll stick to the examples you asked; translate signals
By translate signals I understand two things. Either make a signal stronger (because the origin is far) or to fuse diferent signals (actually, translate means change SX to SY but when you fuse you do that twice to the explanation covers both). I'm going to assume that you talk about fuse signals, if not then ask again
Fuse Signals is quite straightforward. I'm going with the example to fuse S2 and S3 into S4. In the first channel put S4 as output. Touch the [...]
(signal substance signal button) in the first channel and touch "Use Signal Substance". In Input put S2, then put the a
between 2 and maybe 10. That alone is using a Neurocyte to convert S3 to S4.
Same thing in the second channel but instead of using S2 as input, put S3.
That's it. Now the S2 and S3 that enters the Neurocyte comes out as S4.
