Hello everyone - I am trying to create a picture to midi patch, which will read the Y columns of a black and white jitter matrix as velocity values for all 128 midi pitches. I have built the patch, and it works as expected when I manually click the bang which is connected to the uzi that sends out values for rows 0-127. But when I connect a metro to the same bang, with or without overdrive on, it sends much less note information. I have included the patch below., complete with comments and labeling. Thanks!
