2015-10-31/2020-04-09 - From the Robert L. Sipe Inc. website, accessed Oct 31, 2015 — Robert Sipe builds organs "advocating a return to 17th and 18th-century design concepts. Among these principles are low wind pressure, slider wind chests, mechanical key action, the integrity of each separate division housed in the main organ case, and the case itself 'standing high and free...' Following this classical design appropriate to the traditional polyphonic literature for the organ, Sipe organs also incorporate certain modifications to meet requirements of many 19th and 20th-century compositions"
