ChordPainter
Read full descriptionHide full description
Chordpainter creates songbooks of piano songs as chord diagrams without any knowledge of music notes. What has always been standard for guitarists, Chordpainter now also creates this for piano players. Simply input chords via midi or enter them manually. The chords are automatically recognized and can be edited or renamed as desired. Then simply print or export as pictures, by email or into Dropbox. All features in an overview: ------------------------------------------------------------------------ - Creation of chord images with up to 10 notes per chord - Automatic recognition of chords separated for the left and right hand - Input chords manually or via MIDI keyboard - Automatic detection of Midi inputs and display of the Midi source - Bluetooth Midi adapters from Yamaha or QuiccoSound are also supported - Transfer a chord to the current song via button or MIDI trigger - Piano is fully playable with sound, either manually or via MIDI input - Clear button to remove all entered notes - Free definable Midi trigger (setting is stored) - Complete online manual available in the App - Notes, program changes or controller (pedal) are accepted as Midi trigger - Midi Analyzer in the main display for all incoming MIDI events - Intelligent mode to assign chords to the right and left hand - Display of the intervals, separated for chords of the right and left hand - All chords in the song can be sorted using Drag & Drop - Language in the APP can be switched between English and German - Chords can be edited, renamed or deleted also after creation - Optimized user interface for all iPad sizes - When naming the chords, there are buttons for common chord suffixes - Chord images optimized for high-resolution printing on laser printers in grayscale - Songbook view to display all the chords of a song large on one page with Midi scrolling - PDF Export for all songs and demo songs to printout or for use in other APPs - Sound output with real sampled piano sounds including velocity - Sound can be enabled or disabled (setting is saved) - Export der Akkordbilder in die Bilder Gallery oder Dropbox - Constantly expanded list of demo songs, partial with songbook PDFs - Song library with an unlimited number of songs - List view with all songs plus number of chords in the song - Songs can be created, copied, renamed or loaded for editing - Export of chord images to the Gallery or Dropbox - You can also export by email (default email address stored) - Automatic backup of the song library when export by mail or dropbox - Restore the song library with "Open in" function in iOS

Melthaven is a note-triggered phase shifter built to give guitarists and bassists organic, rhythmic movement that syncs to their playing, rather than a fixed LFO. It's also highly suited for a number of synth basses and sounds with sharp attacks and fast decays. Its analog-modeled OTA filters provide deep resonance and character, ranging from wah-like effects to complex, shifting formant textures or even experimental tones, like bubbling or hard, slappy effects. For bright, harmonically dense signals – such as saturated or overdriven tones and synthetic sounds – the effect range also includes growls and glistening sweeps. FOCUSED ON BASS & GUITARS The effect was specially developed to respond to the frequency response and transient peaks of electric guitars and basses. Every pluck, pop, or pick attack re-triggers the phase sweep, effectively turning your rhythmic timing into the "engine" of the effect. USING LOOPS? BREAK THEM OPEN Add various resonant effects like growls, or vintage bark / quacks "after the fact." This unlocks a level of control usually lost the moment a loop is bounced. Instead of being stuck with locked-in sound design, you can now reshape the envelope of any pre-recorded sample, breathing new life into your loop library. FOR SYNTHS & SOUND DESIGN: INPUT DEPENDENT Soft signals like pads or heavy/layered effects can produce wild, unpredictable responses. While such use is outside the plugin's core design, the smoothing feature can tame these re-triggers, yielding a flow that can feel organic and physical in its instability when operating beyond the plugin’s transient-focused comfort zone. MOVING BEYOND ENVELOPE FILTERS The plugin uses low-latency note detection paired with its own envelope generator and LFO, allowing sculpting and even reshaping each note’s modulation profile or filter envelope. It even detects notes that hide under a consistent signal amplitude when using a traditional envelope follower. BASE FEATURES: - Built around a versatile preset from the Pro version to suit a wide variety of applications - Controls: feedback & panoramic position, attack & hold timings, LFO Rate - Smoothing: from envelope shaping to creating a weighted, fluid response, giving note sequences a sense of physical momentum - Low-latency engine: preserves natural playing feel when used as a real-time effect PRO FEATURES - Requires Pro Edition Upgrade (In‑App Purchase): - Additional envelope parameters, several envelope flavors with pre-mapped control subsets - Pro presets encompassing both strong and milder effects, including the quintessential rubber bass - Enhanced stereo phaser modes & internal stereo re-imaging modulator (for formant-like effects and more) - Vintage-style phaser feedback that can optionally build or ramp with each note onset (non-rampable in the base version) - Instant visual feedback via an audio scope with dual-channel envelopes overlaid on the input waveform TECHNICAL NOTES: - Place before creative effects (unless experimenting). It can be used before or after harmonic processing (saturation, amp sims) depending on your preference - Response may vary on sustained notes with shifting harmonic content - Not optimized for upright bass due to its reliance on sharp signal transients - Note detection involves statistical signal processing and confidence intervals. Weak transients and phantom notes could lead to a loss of output determinism, i.e. sensitivity to changes in certain project settings - While it offers multiple layers of real-time control, Melthaven operates primarily as an automatic effect; for full manual filter manipulation, please refer to RealPhase, a separate app PLEASE NOTE: • The Pro Edition Upgrade is offered as a one‑time In‑App Purchase • An AUv3-compatible host is required to use this app • Suported sampling rates: 44.1, 48, 96 kHz

Verdict
The clearest difference is in-app purchases: ChordPainter at none against Melthaven's 1. ChordPainter also leads on iOS requirement (13.0 vs 17.0). Melthaven's advantage is update cadence (every 6 weeks vs every 22 months). On price, ads and device support there is nothing between them.
