Paradiddle 1.1.0 (test build 8)

Test build for trying Paradiddle on a phone. It's signed with the same development key as test build 7, so it installs over it as an update and keeps your practice history and calibration.

How to install: see Install on your phone (English and Spanish).

New since test build 7

• Visual metronome: like the swinging ball on the Alesis Nitro module, a ball swings from end to end and touches an end on every beat, so you can see the next beat coming. It's there when practising a rudiment, playing or practising a style beat, and calibrating.
• Drum grid next to the kit: on a style, the grid sits right under the kit, so you can follow both while the beat plays. Practising a beat on your drums now shows the grid too.
• Calibration: the pad now pulses exactly with the click (before, it flashed slightly late).

Paradiddle 1.1.0 (test build 7)

Test build for trying Paradiddle on a phone.

⚠️ Uninstall test build 6 first. This build is signed with a different development key, so it can't install over test build 6. Uninstalling removes your practice history, calibration and settings. Later test builds are planned to keep this key and install over this one as updates.

How to install: see Install on your phone (English and Spanish).

New since test build 6

• Hear the hands apart: when a rudiment plays, the right hand sounds a little to the right and the left hand a little to the left (best with headphones). Settings → Separate hands in stereo.
• Timing difficulty: Settings → Timing difficulty. Easy (the default) counts hits within ±150 ms; Normal is the previous ±100 ms; Hard is ±70 ms.
• See where to hit: coloured bands around the hit line show where a hit counts, is good and is perfect. The notes land right on the pads, and you can also tap the lanes (left half = left hand).
• Calibration: practising without a calibration now asks you to calibrate first. Calibration itself is easier to follow: short steps, a 4-3-2-1 countdown, a click counter and the pad pulsing on every click.
• Clearer texts: "How to read the kit", the Alesis Nitro Mesh guide and each style's setup are now lists with one step per line.

After installing, calibrate once (the app will ask).

Paradiddle 1.1.0 (test build 6)

Test build for trying Paradiddle on a phone.

⚠️ Uninstall the previous test build first. This build is signed with a different development key than test builds 1–5, so it can't install over them as an update. Uninstalling removes your practice history, calibration and settings: after installing, redo Settings → Calibrate. The next test build will probably need another uninstall.

How to install: see Install on your phone (English and Spanish).

New since test build 5: new app icon

• Two crossed drumsticks in dark ink on a white background.
• With themed icons turned on (Android 13+), the icon follows your wallpaper colours with the same drawing.

Everything else is the same as test build 5, including playing on real drums (microphone or electronic kit over USB-MIDI).

Paradiddle 1.1.0 (test build 5)

Test build for trying Paradiddle on a phone. It's signed with the same development key as the earlier test builds, so it installs over them as an update and keeps your practice history. A future official release (GitHub or F-Droid) will need you to uninstall test builds first.

How to install: see Install on your phone (English and Spanish).

New since test build 4: play on real drums

• Settings → Play on: choose the phone screen, a microphone (practice pad or acoustic kit) or an electronic kit over USB-MIDI (the Alesis Nitro module's default notes are built in).
• What's scored: timing and accents; on the electronic kit also which pad you hit. Hands can't be told apart, so the sticking is a guide only.
• Style beats: a new "Practise on my drums" button plays 8 bars and gives you a score, with live "early / late / wrong pad" feedback.
• Calibration: each input has its own (Settings → Calibrate).
• Electronic kit: connect a USB cable from the module's USB port to the phone through a USB OTG adapter, and turn the module on.
• Microphone: use headphones, and stay silent during the count-in so the app can learn what the click sounds like. The app asks for the microphone only when you choose it.

This is the first build with real-drum input and it hasn't been tested on a phone yet, so feedback is very welcome.

Paradiddle 1.1.0 (test build 4)

Test build for trying Paradiddle on a phone. It's signed with the same development key as the earlier test builds, so it installs over them as an update and keeps your practice history. A future official release (GitHub or F-Droid) will need you to uninstall test builds first.

How to install: see Install on your phone (English and Spanish).

New since test build 3:

• Song lessons: 11 songs now have a "Learn this song" page: the song's tempo, a learning path, a map of every section with the beat it uses, and playback of the whole song (or from any section) with a count-in, a crash at each new section and the kit lighting up. Each lesson is written from published drum guides and song charts; bar counts may be off by a bar or two where charts disagree.
• Two new beats: "Open hi-hat chorus" (rock) and "Disco (closed hi-hat)" (pop).
• A drum sound for each style: tight and dry punk and metal, deep and roomy reggae, soft bossa nova, and so on.
• Fixed: in rudiment practice the falling notes showed the moment to hit 40–95 ms late. Notes are now centred on the hit line at their time and the screen no longer lags the sound. Running the calibration once (Settings) also helps.

New since test build 2:

• Songs that use each beat: 15 well-known songs on 9 beats, as listening examples. Tap ▶ to have your music app (or a web search) play the song. No service is hard-coded and the app still needs no permissions.
• How to learn a whole song: a step-by-step guide on every beat (find the parts, match the tempo, count bars, fills and crashes, play along).
• Kit legend: the explanation of R / L / RF, accents, cross-stick and open hi-hat moved into the ⓘ button on the kit drawing.
