Here's one for the "Why don't I have this yet?" file! Knowing one's keyboard shortcuts are a huge part of being able to work with any degree of speed in a DAW, NLE (non-linear editor for video), or creative visual program. By way of a reminder, one popular solution has been custom keyboards or keyboard overlays, but I've always found these look cluttered for "regular" computer use.
Much ado has also been made of the "touch bar" on the latest MacBook Pros, a touch-sensitive OLED strip which replaces the row of hardware function keys and can display custom functions for various applications.
Metagrid seems to split the difference between these two concepts, turning an iPad into a custom quick-command button surface for your DAW of choice. It communicates with your computer by residing on the same WiFi network, and includes preset (but customizable) templates and icon sets for Steinberg Cubase, Digidesign Pro Tools, PreSonus Studio One, Apple Logic Pro X and Final Cut Pro X, Adobe Photoshop and Illustrator, and more.
Each command can use text only, an icon only, or both. Degrees of optimization are different from one program to another. With Logic Pro X, for example, button sets don't need to intermediate by way of key commands; they drill right through to the command structure of the software.
Notable features include both Mac and Windows support: Though you need an Apple iPad to run it on, it will communicate with a DAW or other supported program residing on either a Mac or Windows machine. Then, there's multi-iPad implementation as of version 1.4. You can connect up to four iPads at once, each specializing in a different function.
For $14.99 on the Apple App Store, I intend to grab a copy ASAP and answer some questions that I'm sure we both have: For example, nothing I saw in the several videos on the site (these are excellent at explaining functionality with different DAWs plus basic concepts and setup) indicates that Metagrid does anything more than buttons and hence the sorts of commands you'd issue from a computer keyboard. Can I create a fader or knob as I might in MainStage, only touch-sensitive? A horizontal strip for precisely scrubbing through a waveform? We'll find out.
For now, check out their teaser video, which is as decent a point of entry into the whole idea as anything. If you have one or more older iPads laying around unloved since you got that shiny new iPad Pro, turning them into an Enterprise D style control surface seems like a great idea.
