[PD] several again

Dear list

Is there an option to set a work folder for the open- and savepanel objects? With that it would not be always in pd/bin when it is open for the first time. ; what is the purpose of the in connection in noise~? ; is there any way of changing the block~ size dinamically? What are it's input commands? ; I'm making a synthesis unit, with several devices. Does anyone know if it is possible to have phase information (besides 1 and -1) in the individual harmonics of "sinesum" option of an array? (like csound's gen9, for those who know it)

(if someone feels the bulk of -small- subjects in the same message confusing, please tell me so, and I can send them in several individual messages - although this way saves bandwidth)
