Hi! While thinking about structure/organization for LDrum, I developed a concept for the gui of a modular system. http://wrstud.urz.uni-wuppertal.de/~ka0394/forum/04-06-15_splitsheet_01.png All happens in one window, with blocks that represent modules. These modules can be input filters (filtering channels, notes, velocity ranges), oscilators, sound filters, amp and everything else known from modular systems. The type of module for a block is determined by a dropdown menu. Other content are the type specific controls. Each block can be split up horizontaly or verticaly to create new blocks (see mockup for a horizontal split). Splitting could be offered in conetx menu or through dedicated buttons. Signal flow starts at the top and goes through top and bottom edges of blocks (no sideway signal flow). Splitting up and mixing happens automaticaly. Of course moduletypes could not be selected freely, because input filters would have to be chained directly, and could not be placed behind oscilators and the like. The system would make it easy to build rather simple chains of modules quite fast. noterange filters would allow to split things up using multiple samples or varying synthesis setups and join it back together at any stage. Alternatively to the block splitting, modules could be layed out on a canvas/grid. But that would require means to resize modules to form various relations. In short I think it would require more interaction for similar results. So this is a rough idea, free to be picked up. If there's real interest (a chance of implementation), it would be my pleasure to further develop it in cooperation. --- Thorsten Wilms
