MIDI pedals made in China, perfectly matched with HX pedals, have a total of 10 pedals, lower than ABCD, higher than 1234, and the rightmost up and down voice group. ABC is just three sounds, 123 is three snapshots, 4 is FS4, you can customize various functions, D set tuning table. From then on, you can use the three stepping nails of the foot. Thanks for Dr. Zuo's special firmware package. Everything is perfect.
