9 two-way switches and 21 1/8" jacks have been added to this roland tr727! Switches toggle between 9 preset bends and 9 of the jacks. These jacks can be patched between themselves or in any combination with the other set of 9 jacks. There are also 3 bonus patch points. Makes every thing from metallic rings to squelching noise to synthy tones.. quite often all at the same time.. have you ever heard bass from a 727? thanks to benders egroup for bendpoint info on this..
