I don't know my problem with Roland G-800 or the way Roland write manual book and even I bought the video manual too. Everytime I come back to G-800 and have problem with manual step into the drum part and the bass part. Anyone, please give me a tip to work on my G-800 with manual drum and bass part. I have a litle express from my personal to Roland product now. The way they program their software of G-800 is so hard. Frankly, I don't have any problem of my Korg and Yamaha from the start out of the box. It's frustrated with Roland. Thanks
