Couldn't configure half open hi-hat at DTX 720


New member
Hi everyone,
It was good to hear "half open" hihat in default hi-hat instrument sound in Yamaha DTX 720. This felt so realistic when I wasn't fully stepping on hi-hat pedal. The problem was coming when I changed hi-hat instrument in to WAV (Hi-hat sound that I imported from usb flashdisk), everything was running good until i couldn't hear half open hi-hat again as well as default hi-hat instrument sound in DTX 720. Can somebody help me to solve this, please ?
