Touch control for your Ableton devices. Skym is a MIDI controller app that allows you to control 4 parameters of your Ableton devices at once. Simply download the app, and install our Ableton script on Mac, and you can connect over USB or Bluetooth to perform expressive sound design. Our free starter Ableton project has some sounds to get you up and running. Skym sends 4 parameters at once. X, Y, Speed (how fast your touch is moving), and Gate (flips on and off with touch). These parameters automatically map to macros 1, 2, 3, and 4 respectively. Combining these layers of control on synths, samplers, effects, gives you access to instant variability and interest in your sounds. Note Skym is a controller and not a sound generator, so the app does not make sound on its own. We only support connection and integration with Ableton on Mac. Mac OS must be 10.11 or later Ableton must be 11.0.0 or later

You sit down at the kit — and play the same three beats you always play. GrooveSmith solves the hardest part of practising alone: deciding what to play. Tap once and you get a fresh practice sheet — a groove flowing into a fill — written out properly, with the audio to match. Not a random note generator: every combination is checked so it sounds like real drumming. YOU DON'T HAVE TO READ MUSIC If you read charts, this is a chart. If you don't, turn on labels and the notes tell you which drum to hit — so you're learning real notation from day one, not a simplified version you'd have to unlearn later. IT GROWS WITH YOU Ten levels, from your very first beat to material you'll have to work at. Each one adds a single new idea instead of a wall, so the next level always feels like the next step — not a cliff. BUILT FOR PLAYING ALONG, NOT WATCHING Hit play and the drums, the click and a moving cursor stay locked together. Change tempo without stopping. Count yourself in. Mute the kit and keep the click, or the other way round. FILLS, AND THE RUDIMENTS YOU KEEP MEANING TO WORK ON Short pickups or a full bar, with the sticking written in so you're never guessing which hand leads. Paradiddles, flams, rolls — properly notated. FITS THE WAY YOU ALREADY PRACTISE Play something once or twenty times. Slow it right down, stop halfway, come back tomorrow. There's no course to work through and no streak to keep — you decide what counts as progress. Rock and pop, straight, half-time or shuffle — and 6/8 and 12/8 when you want them. Works offline. No account, no ads, nothing to sign up for. Made by a drummer who got bored of his own practice routine.
