Hi all, just wondering if anyone would know if those midi foot controllers, such as Yamaha and Behringer, would be able to send chord change messages to a keyboard which is playing one of the inbuilt styles? A mate is a one man band, and would like to do this while he plays guitar. His keyboards are a Yamaha PSRE463, and a Korg EK50. I know neither have 5 pin midi out, but he has one of those host to midi converters which does away with the need to go via a computer. any help would be appreciated. Cheers.
