Actually, the entire let-block is unnecessary, since neither of the variables is used in your adaptation. If you delete it, you also must get rid of the invocation of stop-translation-timestep, whose only purpose here is to reset the unnecessary variable time-signature to the empty-list. This variable is presumably in your source to serve as a collector of time signature grobs as they are encountered. We start with the empty-list to which the grobs are consed. The list is then cleared to make way for a new one. (This list would be have been populated through an acknowledger of the time-signature-interface, which apparently has been stripped here.) Hope this helps, David
