Would love to see what you did.

Here’s the a combination of the two examples I made vids of. One axis controls the note and one controls the cutoff.

define :rMap do |rIn, rOut, v|
  dOut = rOut[1] - rOut[0]
  dIn = rIn[1] - rIn[0]
  dOut / dIn * (v - rIn[0]) + rOut[0]
end

live_loop :foo do
  use_real_time
  b, c = sync "/osc/wek/inputs"
  set :yaw, c
  set :roll, b
end

n = scale(:e3, :aeolian, num_octaves: 2)
live_loop :osctest, sync: :foo do
  use_real_time
  use_synth :tb303
  x = rMap([-3.5, 3.2], [1.0, 131.0], get[:yaw])
  y = rMap([-1.6, 1.6], [0.0, n.length], get[:roll])
  play n[y], cutoff: x
  sleep 0.25  
end
