Almost all Rockman Modules were developed for use by BoSToN on the concert stage. Teams of Electrical Engineers designed and developed these units, not just one person. Certainly Scholz was the creative force wanting various Modules to do specific tasks for the studio and concert stage. But the design and development was primarily done by the Electrical Engineers.
The Modules were internally driven products. Scholz had a direct need for them. In contrast, many other Rockman products were market driven products. Market driven products are designed to compete and achieve sales in the market place. One example of a Rockman market driven product would be the XPR. It was developed to capture some of the early 90's MIDI programmable craze competing with units like the ADA MP-1. Two modules were an exception to the rule. The Distortion Generator which was developed to capture a lower market segment and compete with cheaper distortion footpedals, and later the Dual Loop. These were both market driven products.
Every analog effect unit is sonically different, and Rockman units are no exception. Modules sound quality vary greatly. Some units are stellar, while others can be pretty weak. The highest quality of sound can be derived from a set of Modules by doing direct A / B comparisons. And this is easily done using the Rockman Octopus with 2, 3 or 4 Rockman Remote Loops. It is impossible to get an accurate comparison of modules by pulling jacks to re-route the signal.
Below are the best pictures available of the modules in Scholz's and Pihl's lead setups. One can gleen how each module is set. It should be noted that Scholz plays in the EDGE Mode with Auto Clean® on, and in Clean 1 with the Semi Clean® on. Phil on the other hand has all four (4) Modes available to him.
