After a longer break, I put some time back into the iPianoChords app. On the one hand, now a little clearer without completely changing the look, so there is still not much similar about piano chords in the APP Store. Now optimized for all iPads and landscape mode, I added a few adjustments: In addition to the variants to choose a chord with swipe as chord selection by name, via filter function, as chord reverse search and the scale library, we now have the note view active in all modes. The quiz mode has been revised and now includes chord inversions, this also applies to reverse search. The levels are classified differently as before and designed for beginners. Only the last levels are for the chord masters. And after multiple requests now with midi input. A connected midi keyboard via cable or Bluetooth is recognized directly and you can use it in quiz mode and for reverse search. Some Bluetooth keyboards needs to be connected via GarageBand and can then be used. If there are several midi sources, a dialog is displayed for selection. We also kept the export function for chord diagrams as an image, but I can recommend the ChordPainter in the AppStore. It will create a piano songbook with chord diagrams instead of a notes in minutes. The rest is the same and iPianoChords HD has a Chord Library engine with over 2300 chords. You could select the chord with direct selection by using buttons or the new enhanced filter mode. The Reverse Chord Finder could help you finding the chords for given Piano keys. Also chord inversion are added to the search process, which will offer a very good search result. We added a new Scale Library with 46 Scales in all 12 root notes. There is now a Note System Display available and the display position could be switched in 3 positions. Please note that I'm using a simplified display which may not always 100% musically correct. For all musician are not very familiar with notes, we have added a function to export Chord images. Simply tab your chord notes with red keys, additional solo notes with yellow keys and the left hand chord with blue circle markers. Add a name for your chord image and the chord snapshot function will copy this image to the photo library. --------------------------------------------------- Midi input via cable or Bluetooth Huge chord library Chord with inversions Scale library Chord play mode within 3 octave positions Piano sample sounds Chord selection with chord buttons Limit chord selection buttons Chord selection with filter options Chord search function Simple root note selection Root note display Note name display Alternate chord names Chord formula display Half-tone search pattern Three color chordpainter function Chord snapshot option Note system display Select note system root with 7#/b Language select DE/EN 10 Quiz levels with 1..6 for beginners Quiz with chord names Quiz mode with chord image Quiztimer could be activated Six possible Quiztimer values Plus/Minus quiz answer counter Levels from Powerchords to jazz chords Inversionen im Quiz aktivieren Chord inversion display Landscape and portrait mode Integrated on-screen help Mode select input slide mode Menu selection for input modes

Be rude. Be rough. Be bold. Be tough! Arctic Pro Synthesizer / Vocoder is a modern subtractive synthesizer. It does not aim to accurately model or re-create vintage synths of yesteryear. Instead Arctic Pro offers the contemporary synthesist a rude, rough, bold and tough palette of sound to get stuck into. Including two massively fat HyperOscillators, dual filters, and easy to re-order master effects. While the Vocoder, used in conjunction with a suitable microphone, adds an extra dimension to your musical performance. HyperOscillators =========== Combine two HyperOscillators and one Sub Oscillator for some seriously fat sounds. Layer up to 8 oscillators in unison to create very thick and powerful tones. Spread detune and Mix these separate oscillators in real-time. More than just a "SuperSaw" - it's also a Super-square and Super-triangle. Powerful Presets =========== Legendary sound designer John ‘Skippy’ Lehmkuhl has exclusively designed the factory presets. John has worked as a professional sound designer since 1988 for Korg - making patches, combinations, drum kits as well as creating the sample data for almost every synth Korg has released since the M1. If you have owned one of these historic synthesizers you have heard John's presets. Sharing ===== Arctic Pro includes everything you need to record and share your audio and MIDI with others. Live record to WAV and MIDI files. Use AudioCopy, open audio directly in apps, or share with Kymatica AudioShare. Presets and Banks can be emailed and transferred via Wi-Fi and iTunes Files Sharing.
