Rudra 1.0 is on the App Store and Google Play, for iPhone, iPad and Android. It is the first app from Aeris Nova.
Where it comes from
Rudra started in drum lessons. The teacher used an app built on the rhythm circle: one ring per drum, with each note in its place on the loop. A circle makes a rhythm easy to see, and each drum can loop its own pattern. At home, on an e-drum kit, the practice app we used was in English only. Rudra puts the two together: the circle from the lesson, and feedback for practice at home, in the language the student learns in.
What 1.0 does
Pick a groove, from funk, jazz, rock or world styles, and set the tempo. Mute drums to work on one part, then bring the others back one at a time. Sticking drills train your hands on accents, drags, paradiddles and other rudiments, with the hand for each note next to standard notation.
Connect an e-drum kit over MIDI and Rudra shows every hit as you play it: early, late, miss, or on time. Rudra has mappings for common kits, you can build your own mapping for any other kit, and a latency calibration keeps the feedback tight. Without a kit, Rudra plays the pattern for you to follow.
With Rudra Pro, the pattern editor lets you write your own patterns and share them, from drummer to drummer or from teacher to student.
Rudra is in English, French, Portuguese and Spanish. It needs no account and works offline.
