Understanding Audio Routing in ppooll
Inputs and Outputs in ppooll and ll.blues
At the bottom of many of the ppooll acts, you will find the inputs and outputs of ppooll wherein you can link acts together and direct sound. This section is called ll.blues.
From here, you can interact with the individual volume levels of each act, including how much of the act’s output is sent to ho_st1 versus other acts designated in the output of the act. There is also a menu for changing the display of the ll.blue section, from which more options can be selected.
In default view, the first bar is simply the act's overall volume output.
The mixL and mixR designate how much of the audio is running to the the selected act, and how much is running to the ho_st, essentially creating a wet/dry mix; in this case, the dark blue portion of the bar would be the “wet” part of the mix, and the light blue would be the unaffected “dry” portion of the mix. The milL and mixR outputs are linked from the left output, thus setting the left one will adjust both simultaneously, and setting the right will effect only the right output.
In the outputs section there are four blue menus. From left to right, they generally allow you to do the following:
First output (act): Select another ppooll act source which you wish to direct the audio to from the current act.
Second output (channel): Select which audio channel you wish use to send to the act listed in the aforementioned first output.
Third output (act): Select another ppooll act source (which can be the same source as the first output) which you wish to direct the audio to from the current act.
Fourth output (channel): Select which audio channel you wish use to send to the act listed in the aforementioned third output (again, this can be the same as the second output, though typically these default to left and right speakers).
For instance, if you were to be using the granulator and running it into a filter, your setup may include having the granulator (such as the gg.rainer) run each “act output” into the filter (such as the wrapfilter). The mixL and mixR on the gg.rainer will then designate how much of the audio is running to the filter, and how much is running to the wrapfilter and how much is going directly to the host. The wrap filter should then have its two “act outputs” directed back to the ho_st, or to another portion of the audio chain which will essentially be returning to the ho_st.
Selecting Elements in an Act to be Modulated/Effected
Another important element in managing modular acts in ppooll is understanding how acts with modulating features interact with other acts. Certain acts will allow users to effect one of the values of another act in particular ways. These acts have single outputs that designate the act to be effected, and the value within the act to be modulated.
An example of this may be using the modul.ator act to change the parameters of another act at a designated rate in a specific pattern. If you wanted to use the modul.ator to change the frequency value of the first wrapfiler band, you would select wrapfiler in the modul.ator’s destination-act field, and then the desired parameter to effect in field to the right (in this instance, filt1_freq). Turning the modul_ator on would then have this field altered—likely in a tremolo-like pattern—as designated by the modul.ator values.
