AutoArp vs C.ARP

AutoArp turns your iPhone (or iPod Touch) into a musical instrument that is halfway between a traditional auto-harp zither and an arpeggiated analogue-style synth. Select a chord and strum the "strings" with your fingers to create a retro-futuristic backing to your music. AutoArp is FREE, with a fixed set of songs. Full functionality, including creating, editing and sharing songs, MIDI support and transposing can be unlocked via an in-app purchase (at the lowest price tier). This means you can try it for free and hear the results for yourself! The synth engine features: • square, pulse and sawtooth waveforms, • attack and release envelope controls, • a resonant low pass filter with cutoff and resonance controls, • monophonic or polyphonic playback • tremolo effect with LFO frequency and depth • simple Echo effect Up to 16 chords (12 on iPhone 4s and below) can be selected per 'song' and configured onto the playing buttons, allowing you to switch quickly between songs to load a new set of chords. Alternative bass notes can also be set for each chord. There are 22 chord types, ranging from major and minor to jazz chords like minor 11th and major 7th with a sharp 11th! More Features: * Audiobus support for inter-app audio (even on iOS 6), so you can wire AutoArp up to loads of other great FX, mixing and recording apps * Improved audio engine, built using The Amazing Audio Engine (from A Tasty Pixel), with lower latency * MIDI support, including hardware CoreMIDI-compatible interfaces, inter-app MIDI and even network MIDI (paid version only) * Share songs with other AutoArp users via email (paid version only) * Transpose playback +/- 6 semitones to play in any key (paid version only)

C.ARP is a totally different keyboard. Inspired by old keyboards, omnichords and tape effects, it lets you play chords and melodies as well. Its design makes everything easier for a musician who just wants to play on mobile. Just hold on a button and then swipe or tap on the right section. But if you prefer, you can access chords and notes directly on the notes grid. Pitch them, harmonize, use mod wheel and apply real-time audio effects too. Rhythm section follows you every chord you choose: pick up the style you prefer, adjust BPMs, mute other instrument, change different midi settings, change drums and play them with drum pads. Do arpeggios with different sounds and rhythmic fractions, create different sound environments with delay, reverb and rotation. The design has also been updated for iPads, so you can enjoy the buttons and sections rearranged for the screen size. Record your voice or everything else as a sample, adjust its length, reverse or loop it, make chords and melodies with it and explore other cool features on this 4th version. There's also a tutorial inside! And finally: we added bluetooth out. It means you can connect your iPhone to your Mac and send midi notes right in your preferred DAW. Just follow the guide inside.
