Working with Players : Overview

Overview
A Player is a special type of device that automatically processes, filters and generates MIDI Notes, based on input MIDI Notes to an Instrument device in the rack. Players can also play back MIDI on their own, without any MIDI input; this could for example be pattern sequencers.
The Player devices can be found in the Players palette below Utilities in the Reason Browser:

The basic idea behind Players is that you first create an Instrument device (or instrument track), then hook up one or more Player devices to the Instrument device. If the Player device is a chord generator, for example, you can have it generate chords in the desired key and scale by just playing single notes on your MIDI Control Keyboard. Absolutely great for inspiration!
Player devices are a little narrower than regular devices, and are always created directly above their corresponding Instrument device(s) - between the Instrument and the Mix Channel devices:

General recording methods
Apart from sequencer Players, recording Instrument tracks using Players can be done in two different ways:
This is the default mode and means you just record the notes straight onto the Instrument track from your MIDI Control Keyboard, just as you would a regular Instrument track (without any Player). During playback the recorded notes are then run through the Player, which generates the Player notes in real-time.
This is called Direct Recording and means that instead of recording the notes you play on your MIDI control keyboard, you record the notes that are generated by the Player(s). This way you automatically get the rendered notes onto your Instrument track (as chords, arpeggios etc. depending on the Player(s)). During playback the recorded notes bypass the Player(s), so the result is exactly what you heard when you recorded.
The pictures below illustrates the two different recording modes:
