Volume Control on a Live DnB Jam

By setting some global values for volume controls you can run a set of live loops and easily alter the mix.

What it sounds like:

Code:

# Settings
use_bpm 168
use_random_seed 1001


# Functions
# Get the correct pitch for a sample note.
define :get_pitch_from_note do |note, sample_root_note|
  return note - sample_root_note
end


# Mix
# Setting the values here which will apply them to the sounds in each live loop.
# Change them while running...
set :choir_mash_vol, 0.5
set :bass1_vol, 0.5
set :beat1_vol, 6.5
set :beat2_vol, 1.5
