I understand and I am, for the most part, ok with the design limitations. In practice though, I find myself switching among IRs more than my 11r presets to get a particular feel within a song. To put it another way, I would rather my FCB1010 control the EPSi than the 11r (for most situations), though I know how unrealistic it would be to swap cabs in the real world (but otoh how realistic is it to swap amps in the real world, yet that's what we expect). I still think from a cost-per-unit standpoint this thing is way overpriced. I know adding 2 more buttons (for up,down and not necessarily midi) would be an added design and implementation cost and may require a larger enclosure but what is the $200 really paying for? I don't use the IR they send so that might be a hidden charge of $20 (to put on par with Ownhammer). Don't get me wrong, I would rather have the product in its current state than not at all but it is far from ideal..
