Sometimes we generate some flow of pitch and lengths that we assemble later into OMN material, It can be tiedous to add manually the articulations particularly the "leg" omn instruction, and it can sometimes be useful to have a technique for automated implementation of part of these task, who it will be always possible to edit more precisely thereafter. Below a possible technique based on the recognition and association of patterns of lengths values with articulation instructions. At first, we define a stream of lengths for our phrase: (setf len '(1/8 1/8 1/1 -
