MIXING & EFFECTS
Audio Input/Output Routing
This section covers internal Mixer audio routing functions. Internal audio sources (instruments loaded in the Channel Window) are sent to the Mixer insert track set
by Channel settings FX selector, as shown below:
NOTE: In the example above Mixer Track 2 is selected and so the Track Send switches (18), Soundcard Input / Output options (6 & 7) and Mixer Track Properties
(Green) change to show unique settings for Mixer track 2. Usually the only Mixer track with a Soundcard Output (7) selected is the Master Mixer track.
Some points about internal and external audio routing:
- Loading and routing instruments to Mixer tracks - Open the Plugin picker (Ctrl+F8 or
middle-mouse click on the FL Desktop) then drag the instrument from the Plugin picker & drop it on the desired Mixer track. The track will be renamed after the plugin and routing automatically made. You can also
double-click instruments in the picker and they will be sent to the selected Mixer track.
- Routing from existing Channels to Mixer tracks - An efficient way to route one or more Channels to Mixer tracks is as follows:
- 1. Right-click the Channel Selector LED's for each Instrument Channel to be routed to the Mixer (Right-clicking allows multiple selections).
- 2. Right-click the target Mixer track and select 'Link selected channels > to this track' from the pop-up menu. OR use 'Link selected channels > starting from this track' to assign
multiple Channels to multiple Mixer tracks.
- Internal routing - The Mixer 'Send switches'  (18) allow audio to be re-routed internally between Mixer tracks. When a send switch is activated
two parallel and independent audio paths are created between the Mixer tracks:
- External routing - Audio sent to and received from your soundcards input and output jacks is set by the Input / Output selectors (6 & 7).
NOTE: that each Mixer track has its own input and output options. For example, if you have an audio interface with 16 microphone inputs, then you have the option of setting 16 unique Mixer channels to receive each of these soundcard inputs. It is even possible to set
two or more Mixer tracks to receive the same input or send to the same output. When '(none)' is shown, this means no external soundcard input or output is selected for the selected track. By default, the Master Mixer track 'Output' is the routed to the soundcards
main outputs (usually the main/front Left/Right channels). However, by routing another Mixer track (other than the master) to other soundcards outputs (e.g. the rear channels of 5.1 surround-sound card), you can create
a separate sub-mix for band headphone monitoring or studio monitoring.
- Parallel internal / external routing - It is worth noting that the Mixer track Input / Output (6 & 7) can function in parallel with the internal routing
functions so that any track can receive external and internal audio sources simultaneously OR output to the Master Mixer track and any other available soundcard output. Mixer routing is described in more detail below:
How to Route Audio
- Mixer tracks - can take an input audio signal from one or more internal Instrument Channels by setting the Mixer Track Selector to a given track OR one external source (6). After processing the input they can pass the audio to another
location, usually the Master track (1) but it can be another Mixer track (18) or directly to a soundcard output (7).
- To send audio from one insert track to another - Select the source track you wish to send FROM and then Left-click the send control switch (18) on the destination track you want to send TO. A send-level knob will appear on the destination track that can be used to change
the level of signal passed to the destination. By default the SOURCE track will maintain routing to the Master track - If you don't want to create a parallel path to the Master Mixer track, select the source track and disable the send switch on the master by Left-clicking it.
- External Inputs - Most ASIO drivers provide inputs (6) for microphone, line-in, etc. You can route these inputs to any or all Mixer tracks. Note that the ASIO inputs will not replace but mix together with any input audio
the track receives from other sources (instruments, other tracks, etc).
- External Outputs - Most ASIO drivers provide outputs (7). You can route any Mixer track to any
- Surround sound 5.1 or 7.1 - You can set a group of Mixer tracks to output (7) to the individual channels of a 5.1 surround system for surround-sound mixing.
A Surround sound template is available in the File menu > New from template > Utility > Surround panner. After opening this template, select soundcard outputs using the
Output menu (7) to match the pre-named Mixer tracks.
- FL Studio as VST - Additional outputs also appear when using the FL Studio multi output VSTi connection.
Limitations of routing:
1. If you are using the 'Primary Sound Driver' audio driver only one track at a time can output to the primary output (usually this is the Master Track). This limitation does not apply if you use an ASIO driver, then any Mixer track
may be routed to any available output (7).
2. FL Studio will disable certain routing choices if this would create a circular dependency (for example trying to route a track to itself).
3. Send tracks (4) can not be routed to insert tracks (3).
4. Use the Send Levels (15) knobs to adjust the amount of signal sent from an
insert track to the send tracks.
5. The specially named 'Selected' track (4) can only receive audio from the currently selected track. Its main purpose is to hold an Edison
plugin, ready to record any selected tracks audio OR visualization plugins, such as WaveCandy.
Prepare for Recording
The disk icon (17) prepares a track for audio recording (to a *.wav file). The
input selected at (6) and/or any internal audio routed to that track will be recorded.
