# =================
# Mapping MIDI Devices
# =================
# You can map MIDI devices to specific ports and channels using the mapping directive.
# This allows you to route MIDI input and output to different devices.
#
# Syntax:
# `mapping:`

# Mapping between devices and ports with aliases
mapping:
    out("MyDeviceA")
        -> port(1)
        -> alias("myDeviceA")

    in("MyDeviceB")
        -> port(2)
        -> alias("myDeviceB")

# Then, you can bind patterns or synths to the mapped devices
# For example we tell to send the kickPattern to Device A on port 1 and channel 10
bind myKickPattern -> mapping.out.myDeviceA with {
    port: 1,
    channel: 10
}

# And we tell to receive MIDI events from Device B on port 2 and channel 10 to play mySynth
bind mapping.in.myDeviceB with {
    port: 2,
    channel: 10
} -> mySynth

# You can also listen for MIDI events from the mapped devices
on mapping.out.myDeviceA.noteOn:
    print "Device A Note On"

on mapping.in.myDeviceB.noteOn:
    print "Device B Note On"
