The BlueScalesTrainer was created by good motivation targets for 2019. Not loosing weight this year, but finally know where notes are on which fretboard position on my guitar to play solos. Like everywhere, this require a lot of practice and I started direct in the AppStore looking for suitable apps. Although there is a lot dealing with Scales, it is either too much, visually too small and often not helpful for practicing. The features I missed are now available in the BlueScalesTrainer: * The scales should be displayed while playing, so it needs a music audio player * New songs should be analyzed because I'm not able hear the key of a song * The scales should then be displayed individually in large size and as an overview, matching the selected song * Overview and single view of scale patterns should be switched by foot pedal * A fretboard view provides a complete overview and should also be able to hide notes. Thanks to my app BlueJamPlayer, I already had the basis for the audio player, song analysis and control via foot pedal. I also took over the effect section, so that you can use the 7 audio effects in the BlueScalesTrainer as well. Here are the extensive functions that I have integrated in the BlueScalesTrainer and everything without subscription, InApp Purchase or advertising: - The main Scales are included: Major, Minor, Pentatonic Major, Pentatonic Minor, Blues Major and Blues Minor - In total 360 scales for your training target to master your guitar solos - Per scale type each of the 12 keys and their 5 patterns according to the CAGED system could be selected - Scale view in 3 modes: Pattern single, Summary and Zoom view - New added large fretboard view, where either root notes, chord notes or all notes of the scale are displayed - Switchable display of the notes or note position in the scale - The player can also be controlled via Bluetooth from PagerTurner foot pedals - Alternative scale views can be switched via foot pedal - The pitch can be adjusted without changing the speed - Also the speed is adjustable without changing the pitch - Free configurable effects (reverb, delay, flanger, equalizer, filter) to improve the sound - All songs in your iTunes library can be used - Songs are analyzed for the key, so that the matching scale will be selected automatically - The BPM will also be analyzed and effects Delay/Flanger will be set to this BPM - In order to sort your session better, there is a playlist management with 16 playlists - Especially for practicing difficult passages, the A->B Play mode is optimal - For the direct start 14 loop songs of different styles already available Hope you enjoy learning Scales with BlueScalesTrainer!
