Here's a video of DroneStation in action. While I have a fairly good picture camera, my video camera is not so much, akshully. As a result, it's kind of hard to see what's on the screen. Can you trust me when I say it looks really nice?

Here's a screenshot of the main control screen. On the left is the four "keys." You can set the note each key will play. The X axis of the keys is volume, and the Y axis (after the initial hit) is pitch. So when you first touch the key, the pitch is selected by the note number, but dragging it up or down will change the pitch accordingly, as you can clearly see in the video.

Here's a second screenshot. As you can also make out in the video, the abstract shape in the center gets larger or smaller based upon the volume. The color changes from blueish (at an LFO depth of 0) to sea green (at an LFO depth of Full.) The shapes move based upon the speed of the LFO. In this way, not only do you have a fairly slick display, but you have good visual reference as to where you're at with the settings, should you need it.

Here's a shot of the settings screen. It's a 2-osc synth with a resonant 4PLP filter, basically, and does all the things that such a synth should do. It remembers the state you left it in when you start it again; I haven't quite hacked the preset portion of things yet, and I think the state memory is a fairly good substitute in the interim.

I'm going to submit this for approval this week at some point; it'll be $1.99.
