# Lesson 6

# In this lesson, you will learn about some special
# features of Sonic Pi that let you play around with
# and change sounds.

# General Instructions:
#
# This lesson contains three examples and three
# exercises (A, B, C).
#
# To listen to an example, change "comment"
# to "uncomment" on the "comment do" line,
# then click the "Run" menu command at the
# top of the Sonic Pi editor window.
# When you are done with the example, turn
# it off by changing "uncomment" back to
# "comment," and move on to the next section
# of the lesson.
#

# Synthesizers
# Effects
# Samples

# Synthesizers: Sonic Pi has about twenty different
# synthesizers (synths) built in. You can easily change
# from one synth to another with the use_synth command.
# Here are some examples of synth names: Beep, Blade,
# Chipnoise, Piano, Pluck, Saw, Sine. You can find a
# complete list of synths in Sonic Pi by clicking on the
# "Synths" tab on the help menu bar (between the "Examples"
# and "Fx" tabs). When you type the "use_synth" command,
# Sonic Pi provides an auto-complete menu giving a list
# of synths to choose.

#  Example 1 - Changing the synthesizer

comment do
  use_bpm 100
  use_synth :prophet
  myNote = 60
  myTime = 1
  13.times do
    play myNote
    sleep myTime
    myNote = myNote + 1
  end
end
#

# Exercise A
#   Change the synth in Example 1 to the following synths:
#     Chipbass
#     Dark
#     Ambience
#     Fm
#     Growl
#     Hoover
#     Prophet



# Effects. Effects are processors that change the
# characteristics of a sound. Effects can be added
# to sounds created within a do...end block of code using
# the with_fx command. You can find a list of effects
# available in Sonic Pi by clicking the "Fx" tab on the
# help menu (between "Synths" and "Samples").
#

# Example 2 - Effects:

comment do
  use_bpm 100
  myNote =  60
  myTime = 1
  13.times do
    with_fx :echo do
      play myNote
      sleep myTime
      if myNote < 67
        myNote = myNote + 1
      else
        myNote = myNote - 2
      end
    end
  end
end

#

# Exercise B - modify Example 2 to use the following
#   effects:
#     Distortion
#     Flanger
#     Octaver
#     Reverb
#     Vowel



# Samples. Sonic Pi provides a number of recorded samples.
# You can trigger them using the sample command followed
# by the name of the sample. The samples are organized by
# type, with a prefix for each type. For example, drum sounds
# use the prefix drum_, looping sounds have the prefix loop_.
# You can find the a list of samples using the "Samples" tab
# on the help menu (between "fx" and "Lang").

# Example 3 - Samples:

comment do
  use_bpm 100
  myNote = 60
  myTime = 1
  13.times do
    play myNote
    sleep myTime
    myNote = myNote + 1
    sample :ambi_swoosh
  end
end



# Exercise C
#   1) modify Example 3:
#       a) set myTime = 3;
#       b) delete "myNote = 60" line
#       c) delete "myNote = myNote + 1" line
#       d) move "sample :ambi_swoosh" line
#          above "sleep myTime" line
#   2) Change the code to use the following samples:
#       a) ambi_drone
#       b) ambi_piano
#       c) ambi_choir
#       d) drum_heavy_kick
#       e) drum_snare_hard
#       f) drum_cymbal_open
#       g) glitch_robot1
#       h) misc_burp
#       i) guit_harmonics
#       j) vinyl_scratch
