I just Googled Steinberg Groove Agent for the heck of it. I purchased this item back in 2007, and was so utterly disappointed with it. It didn’t integrate with ProTools as promised and it was basically a runtime drum machine with no midi pattern drag n’ drop nor editing.
I am surprised to see that you’re still pushing this product and not at all surprised to see the negative feedback on it. I wonder if you have ever made any attempt to reimburse customers for the initial “Beta sold as product” version or offered any free upgrades to those users?
I since threw my copy into the trash as it never offered anything of use nor did my laments on the message board. I am a thoroughly committed EZ Drummer user now, and have been so amply rewarded by switching.
