My Yamaha DXR12 came today. I haven't played through it yet because I'm having trouble loading IR's. I have 40 IR's imported into the editor. They show up when I click Impulses. But I can't seem to get them to load into a patch. When I select an empty block and then select Impulse Response, there are only two sample IR's available to put into the patch block. I tried to copy from my Impulses list but I can't paste into the patch block. I tried dragging them from my Impulses list, but they don't latch to the block. A bunch of the IR's that are in my Impulses list, were loaded into my Helix when I bought it and have OH at the beginning of the name. I assume they are OwnHammer IR's. I'm also trying to place my 3 Sigma Audio IR's I bought. Neither work. What's the dumb trick I'm missing?
