ED_SC55 The program ED_SC55 (under MS-DOS) is an editor designed mainly for the Roland Sound Canvas SC-55. Realized with a graphic mode of 640x480 pixels it looks like a Windows program (windows, buttons, etc). The software allows users to change easily all sound parameters of each voice and to store them up to in a maximum of 20 settings that can be recalled, while playing, by pushing only one key (0 to 9, A to Z). Particularly useful to those players that use the SC-55 as sound generator and need to change instruments in real time. The present version V1.0 is freeware. Hardware/software requirements: - microprocessor from 80386; - minimum conventional memory amount of 400 kBytes; - VGA (S-VGA); - MIDI interface MPU-401 or compatible (used as UART); - mouse with two buttons; - MS-DOS from 6.0.
