Today, I just sold a Simmons SD5K module. The buyer is now telling me that the hi-hat is not working on the module (will not close.) I have had major issues with the hi-hat pedal, and it will not work on my Alesis DM Pro or on the Simmons SD5K before I sold it. I assumed the pedal was defective, and had it in the scrap pile. Has anyone ever had this issue before, or know how to resolve it? Maybe even know how to re-initialize the Simmons SD5K? Your help is greatly appreciated, and I thank you all in advance.
