App info is currently processing and/or the app is not yet fully available for sale on the US App Store. Wee this thing sounds amazing. Comes with 200 presets, good for a synth noob like me.
This is a video of an alpha version. http://www.youtube.com/watch?v=FaAeLEdwW3M I picked it up yesterday and was already thinking of using it for something I had tonight. It sounds terrific and is really easy to program. I have already created a handful of sounds. It has a very nice arpeggiator. I like being able to use the mod wheel for varying parameters. Most everything is easily accessible directly on the main screen. This is a really nice package and it amazes me that it is $5. Many of the sounds are a bit too effect heavy. They use a delay that lasts awhile. I couldn't get a slow enough LFO for doing really slowly rolling filters. Maybe I was not using the right knob. There also seems to be a bug. If I switch apps, when I come back to Horizon, the patch selector is messed up and selecting category filters does not work right. Removing the app from memory resolves it. The biggest drawback for me is I find this mainly as a standalone live performance synth. It has audio copy (I think), but there is no defined tempo. If you like old analog synths, this is easily worth the $5 intro price.
