Compose cadences on the go! Choose from snares, tenors, bass drums, cymbals, and even drumset if you want. In a league of its own, DrumToolz also lets you manually input exercises for drum set, marching snare, tenors, and bass drums while generating new creative ideas using what you input, all shown on an editable music score. You can also upload your beats to your social profile, play what other users are playing, save rhythms, practice snare drum rudiments, and learn from a full library of dynamic exercises for both snare drum and drumset! It's perfect for all skill levels, from beginner to extremely advanced, drum wizards. Works great for sharing drum cadences with your drumline. Isolate individual snare, tenors, etc. parts. Practice the simplest to the most complex of beats and rhythms. If you can think of it, you can input it and practice it! Anything from beginner rock beats, to the most complex of jazz beats and fills. Lastly, top off the notes with ornaments: stickings, accents, flams, diddles, and cheese. Input up to 50 measures. When practicing drum set beats, choose from a ride cymbal, hihat, hihat foot, kick drum, snare drum, and three toms. Input everything from whole notes to thirtysecond notes and tuplets. Also, for tenors, choose from four tenors and a spock. Bass drums - five bass drums. Marching snare - a realistic marching snare and a ping sound. Generate new ideas (modifications) using beats that you input into the score. Choose from several modification methods: Add, Shuffle, Substitute, Permutate, Repeat, and Random. Modify individual parts of the beat (ex: kick drum only) or the entire beat if desired. Custom snare exercises. Choose the time sig, subdivisons, tuplets, stickings, accents, flams, diddles, cheese, drags. Save the beat in the score for later practice, keeping the modifications if desired. If the modifications are kept, this turns the beat into an endless, dynamic exercise! Each time you generate an exercise, it uses the modifications to give you an entirely new beat. String together saved rhythms and practice them as one exercise, perfect for practicing beats followed by a drum fill. Upload your beats to your profile. Find and follow other drummers in the social network. Learn from them as you see and practice what they have uploaded to their profile. Share your beats through PDF links and files. Also, share your entire score with a link that pre-populates the score into the app. Learn from a full library of dynamic drum set and snare drum exercises, essential and hybrid rudiments included. For highlighted rhythms, shuffle around groups of notes, stickings, accents, flams, diddles, and cheese.
