Hi,

The manual mentions:
“Expression signals can be defined with a custom mathematical expression. The expression may
also refer to other signals, which are defined with the Inputs parameter. Expression signals cannot
be used as inputs for other expressions.”
But other than that, no.

The links editor is a (JavaFX) table, which by default does not commit new values on defocus, instead you must press Enter to confirm new value (we should change this at some point as this is not very clear).

The “(random*100) mod 54” could be done by first making one Random signal, then adding that to a link variable e.g. “a”, and then entering “(a * 100) % 54” for the Experssion.

It is tested for simple uses, but the built-in functions of https://lallafa.objecthunter.net/exp4j/v0.3.11/ should work (Simulation Server uses that to calculate values at the moment) . In addition there is variables “Pi” for pi and “t” for simulation time in seconds.
