Block-level use new MIDI defaults

with_midi_defaults

Specify new default values to be used by all calls to midi_* fns within the do/end block. After the do/end block has completed the previous MIDI defaults (if any) are restored.

Introduced in v3.0

Example

# Example 1

midi_note_on :e1
with_midi_defaults channel: 3, port: "foo" do
  midi_note_on :e3
end
use_midi_defaults channel: 1  
with_midi_defaults channel: 5 do
  midi_note_on :e2
                  
end
  midi_note_on :e4

# Sends MIDI :e1 note on with default opts
 
# Sends MIDI :e3 note on to channel 3 on port "foo"
 
# this will be overridden by the following
 
# Sends MIDI :e2 note on to channel 5.
# Note that the port is back to the default
 
# Sends MIDI :e4 note on to channel 1
# Note that the call to use_midi_defaults is now honoured.
