Hello,
I managed to deform some letters and to scale them reacting to a sound file using Geomerative and minim libraries, but how can I keep the letters deformed?! Why once the sound position is 100px away the points get back to their original positions?!
Thanks a lot in advance for your help.
Best,
L
