If you want to increase the gain of a single connection, using [mtx_*~], is this more CPU friendly:

[0\
|
[element 1 1 $1(
|
|    [osc~]
|    |
[mtx_*~]

than this:

[element 1 1 1(
|
|    [osc~]
|    |
|    [*~]
|    |
[mtx_*~]

I mean, does [mtx_*~] calculates the gain for a given connection only, with [element(, or does it calculate the whole matrix?
Hope what I'm asking is clear?
