Would you like to improve your drumming? ProJammer will have you jamming like a pro in no time! ProJammer represents a revolutionary way to learn new drum skills quickly. All you need is your drum kit, some headphones and ProJammer – it’s like having your own private drum instructor, plus a backing band! ProJammer is a play-along app like no other: - ProJammer contains multi-track original music (with real instruments, not fake MIDI imitations) that you play along to. - The original play-along music is specifically written to complement each associated drum lesson. - The play-along music is provided in loop form. The loops allow you to get in the groove and play until you feel comfortable, without ever needing to restart the song. - Each musical loop is accompanied by a drum transcription that corresponds to the drum part in the musical loop. - You can change the loop speed! Play along with the loop at a slow speed to learn the pattern, then accelerate the loop to build your chops! - You can selectively mute instruments and the built-in metronome to match your learning objectives. For each loop, you can start by listening to just the drum track to get familiar with it. Next, add the other instruments (guitar, bass, and keyboards) with a few clicks and play along! When you get more confident, you can remove the drum track (and also the metronome), and it’s like you are playing with a backing band! Play the pattern that is transcribed, or improvise your own part! ProJammer is a free app that contains five built-in musical loops plus transcriptions. The built-in loops cover Rock, Funk, World, Blues, and Latin beats. Additional packs of loops can optionally be purchased via in-app purchase. ## Key features - Multi-track original music - Drum transcriptions - Adjustable loop speed - Instrument muting - Built-in metronome - Looping practice ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Rock Loops 01 | $1.99 | one-time | | Funk Loops 01 | $1.99 | one-time | | Blues Loops 01 | $1.99 | one-time | | Latin Loops 01 | $1.99 | one-time | | World Loops 01 | $1.99 | one-time | | Strolling Bones | $0.99 | one-time | | U Funky | $0.99 | one-time | | Praise Rock | $0.99 | one-time | | Trappist EDM | $0.99 | one-time | | Covered Wagon | $0.99 | one-time | ## Recent user reviews (10 of 26) All indexed reviews: https://appshunter.io/ios/app/projammer/id1161961316/reviews.md ### 1/5 — Funzt nicht wie versprochen! *2024-11-25, version 1.2.3* Bezahlen funktioniert, Laden der Loops nicht. Mehrfach probiert, mehrfach erfolglos. Kann vorige Rezension nur unterschreiben. ### 1/5 — Loop *2024-10-15, version 1.2.3* Auch bei mir erhielt ich für meine Käufe keine Loops. ### 3/5 — Purchases won’t work. Otherwise good. *2023-09-12* Good for getting my drum students to play along with and do some improvised fills and variations. The extra loop packs I bought won’t load into the app however and the developer website is just a blank page. No support. Could be great. Actually quite frustrating. ### 1/5 — Achtung! Gekaufte Loop-Packs erhält man nicht *2023-07-18, version 1.2.3* Loop-Pack bezahlen funktioniert, das Geld wird eingezogen, aber geladen werden die bezahlten Loop-Packs nicht. ### 5/5 — Great for practicing *2022-12-27, version 1.2.3* My instructor recommended this app to improve my timing. Having fun so far. Nice easter egg too ### 1/5 — Gekaufte Inhalte erscheinen nicht in der App *2022-01-22, version 1.2.3* Gekaufte Loop-Packs werden nicht runtergeladen. 3,98€ für nichts ### 1/5 — App is cool but bug is limiting it *2019-10-01, version 1.1.0* This seems like a great app but... the menu blinks when I tap on it and goes away. The only song I can play is Boots and Cats and can’t change it. Will gladly change my rating and review once the BUG is fixed. Using iPad Pro with iOS 13.1 (Looks like it works fine on iOS 12.3 - installed on friends iPad to see if it works) ### 5/5 — High Quality *2018-09-13, version 1.1.0* This application seems to be very high quality and really helpful. It’s useful for a lot more than just practicing drums, you could practice bass/keyboard/guitar as well. Bonus points for much better rhythms than most applications of this type which mostly stick to basic 4/4 stuff. I’d love to see the notes for the loops list the # of measures in the loop and what key the loop is in for users who want to play along on something other than drums. ### 5/5 — Casual musician *2017-01-25, version 1.0.3* Fun & fresh loop tunes! Love that I can adjust the speed to my level for various instruments. ### 5/5 — music teacher *2017-01-25, version 1.0.3* Great new way for my students to practice improv with a variety of instruments, and at different levels! They love the cool new way to play along with this app. ## Frequently asked questions about ProJammer ### What does ProJammer do?
