I'm kinda new to creating music so I'm not sure if I need a sequencer like a QY70. Right now I have a Roland VS1680, Roland MC303, Korg EA-1, and an Akai S3000XL in my setup. I also have access to a pc. I'm into creating dance music such as techno, R & B, and Rap. I'm not a keyboardist, but I've heard a sequencer will play chords you program into it and sound like someone playing one. Can I midi all my equipment to this sequencer then set each one to play when I want them to? Can I program it to play different sounds from my sampler? If anyone can help me I would truly appreciate it.
