Composia vs InstaChord

Create compositions and practice music theory with Composia. Export your creations to MIDI or PDF. Composia is a project I started in order to apply music theory concepts - and help me learn them. There are a number components that I've had to build: theory, database, sheet music generation, menu system, and synth. - Theory So far I have programmed in Keys, Solfege, Scales, Chords, Phrases, Figures, Compositions and Part Writing. Getting the part-writing to work was very challenging. It doesn't follow the rules 100% in order to allow the user some more freedom to create. - Database I had to create a way to store compositions in such a way to retain context and allow AI to use for generation in future versions. - Sheet Music Generation The most difficult part so far has been the sheet music generation & exporting with realtime pinch zoom. At first I thought it wouldn't be SO complicated but turns out allowing for 4 voices and all the variations of notes and rests is very tricky. There is still a lot to do but it's at least stable now. - Menu System Since I had to keep creating different menus to test various aspects I decided to go with a "neuron" menu system. This was also a giant pain to build but has made things easy once it was put into place. - Synth This is currently the weakest part of the project, but it produces a basic sound for the notes. I decided to use overtones to make a note sound louder. The louder the note the more overtones are attached.

InstaChord-i is an easy-to-play musical instrument, a learning tool for chord progressions, and an auxiliary tool for composing. You can experience an innovative electronic musical instrument "InstaChord", which has raised about $770,000 by crowdfunding with this app. https://instachord.com (This app was developed under the supervision of Mr. Yuichi Nagata, the developer of "InstaChord".) ■ Features ◆ Can perform music instantly You can enjoy playing like a guitar or piano by tapping and swiping the pads while holding down the buttons with the chord symbols (C, Dm, etc.). There are fundamental chords based on music theory on the screen, so you can make a song just by choosing buttons loosely. ◆ Guitar or Piano You can choose from two types of interfaces, "guitar strings" and "piano keyboards". ◆ Play various chords If you press "~" (swap button) at the same time, the major and minor of the chord will be switched. (Ex: "F" + "~" → "Fm", "Em" + "~" → "E") You can also play various chords by pressing the chord buttons (7, M7, sus4, etc.) at the same time. * Some functions are paid options ◆ You can play any song When you set the Key setting to the key of a song, the fundamental chords (diatonic chords) used for that song are assigned to the buttons on the screen, so you can easily play songs with any key. Since numerals (scale degree) is written on the screen, it is ideal for learning chord progressions. ◆ MIDI Connection - Virtual MIDI: Control ohter Virtual MIDI compatible synth app on your device. * GarageBand doesn't support Virtual MIDI input. - Wi-Fi: Send MIDI notes to PC or Mac via Wi-Fi. * Windows PC requires connection software such as rtpMIDI. - BLE MIDI: Send MIDI notes to Mac or other iOS device via Bluetooth. ■ Playable chords major, minor, 7, M7, m7, mM7, add9, m9, sus4, dim, aug, m7-5 * Some chords are paid options ■ Built-in 28 Sounds * It is different from the built-in sound of the hardware version of InstaChord. * Some sound sources are paid options Ac.Guitar E-Gt.Jazz E-Gt.Clean E-Gt.Dist Sitar Koto Ac.Piano E.Piano Vibraphone Marimba Agogo Lead Synth Polysynth Brightness Rock Organ Church Organ Accordion Strings Synth Strings Voice Oohs Trumpet Synth Brass Flute Whistle Warm Pad Bowed Grass Metal Pad Rain FX ■ InstaChord-i website https://instachord.com/app
