Using FL Studio. -

This section explains the various features of the Mixer, there is also a

Mixer video tutorial here. The Mixer contains 64 insert tracks (3), 4 send tracks (4) and a master track (10). Any number of insert mixer tracks can be displayed depending on the mixer state (left click on the edge of the mixer and stretch). To access tracks use the Track Scroll Bar (2).

Select a track by clicking the pan or fader controls, scrolling with the mouse wheel or left-clicking on the track label area. Once selected, the track will appear highlighted and it will have additional functions available in the Mixer Track Properties panel (9), input/output options (6, 7) and FX slots (8). Track 1 is highlighted in the picture below. For a detailed description of recording sounds from/in the mixer see the Audio Recording page.

Mixer Menu - Contains view, recording, Track linking, renaming and coloring options, click here to learn more about the options.
Mixer Track Scroll Bar - This will slide the visible range tracks within the mixer window.
Mixer Insert Tracks - The output of all audio instruments in FL Studio is routed to one of the 64 available insert tracks. In the default Mixer setup, once the audio signal is processed with the integrated filters (equalizer, volume and panning - 9) it is then sent to the master mixer track (10). It is also possible to route the audio of a mixer track to any ASIO output (7 - for users with ASIO enabled sound cards) or even another insert track (18). This internal re-routing is a very powerful feature allowing you to create advanced mixer setups with groups and subgroups of insert tracks.
The labels can be right-clicked (or press F2) to rename the track or recolor it. Quick linking of channel/s: From the Channel window use the Channel selector to select the channel/s you want to route to the mixer track, then select the desired destination mixer track and click Ctrl+L. There is also an option to sequentially link Channels to tracks starting from the selected track. Shift+Ctrl+L.
Send Tracks - there are 4 mixer tracks dedicated to send functions, although any track can serve as a send, (18). The send tracks do not receive a direct audio input from the instruments, but they can receive audio from one or more of the 64 insert tracks (you can adjust the amount of signal sent by each insert track with the Send Level knobs (15). The purpose of send tracks is the ability to setup common effects (for ex. reverb and delay) once in a send track and then being able to route multiple insert tracks audio to it, as opposed to adding the same effect in each insert track, wasting CPU power.
Big Peak Meter - Can be hidden using the Mixer menu (1) > View > Options. Output is in dB. See Levels and Mixing to learn more about using peak meters in FL Studio.
External mixer input - ASIO hardware inputs and some VSTi inputs can be selected here.
External mixer output - ASIO hardware outputs can be selected here. Typical uses include live-use where one channel is sent to headphones for monitoring previewed samples/mixes while the main mix goes to the PA OR to create a surround sound sub-mix by sending several mixer tracks to the relevant surround channels of your soundcard.
FX slots - Up to 8 independent FX may be added to each mixer track. To load an Effect: Left-click on pop-up menu arrow at the left end of the slot and use the 'select' option. If you need more than 8 Effects, use the 'Send' feature (18) to route the output of one mixer track to another. To open an Effect GUI interface: Left-click on the name of a loaded Effect, a loaded Effect is displayed in FX slot 7 above.
Mixer Track Properties - For more detail click here. Parametric EQ, Stereo Separation , Pan , Swap Stereo Channels, Invert Phase . The All these features are automatable. Panel (A) is the graph for the Parametric EQ, left-click to control center frequency (left-right)/amplitude(up/down) or right-click to control bandwidth (left-right)/amplitude(up/down). Panel (B) can be left or right clicked to gain simultaneous X/Y control over Pan and Volume. Panel (C) holds the controls for Plugin Delay Compensation.
Master Mixer Track - All audio output of FL Studio is routed through the master mixer track for final processing before the final output (unless an insert track is routed out of the mixer to an ASIO output - 7). In light of this, the Master track isn't a good place to record external ASIO inputs (6) as the external and internal audio will be mixed together and recorded to disk.
Small Peak Meter - See Levels and Mixing to learn more about using peak meters in FL Studio.
Mute Switch - left-click to mute/un-mute the individual track, right-click to solo/un-solo the individual track.
Pan Knob - this function is also duplicated in the Mixer Track Properties area.
Level Fader - Can be automated right-clicked and linked to controllers. This function is also duplicated in the Mixer Track Properties area.
Send Knobs - When the 'Send' switch is activated (18) this knob (on the destination track) controls the signal level received from the source track.
FX Enable/Disable Switch - When deselected this disables all the FX in the FX slots (8). This only becomes active once an FX is added to a FX slot.
Track Recording Switch - When selected (orange) the track is armed and any audio (internal or external (6)) will be recorded to disk.
Track Send Enable Switch - Left-click to enable audio to be passed from one track to another, turns orange. Right-click to route to a specific track, master routing disabled.

NOTE: Most controls are automatable (right-click and select 'Create automation clip').
