[[ A STRANGE MUSIC TOOL FOR MANIAC MUSIC LOVERS! ]] MIDIWriter is a unique app that converts keyboard input into MIDI note messages. Each character you type instantly produces sound. You can also enter a phrase and play it back as a sequence with adjustable tempo and loop options. KEY FEATURES: Built-in Sound Engine: No external app required! MIDIWriter includes a built-in General MIDI sound engine with 128 instruments and 9 drum kits. Just type and hear the sound immediately. Phrase Playback: Enter any text and play it as a musical sequence. Adjust the tempo (1-480 BPM), enable loop mode, and let your words become music. Space characters can be used as rests. Drum Mode: Switch to drum mode to play percussion sounds. Choose from 9 GM drum kits including Standard, Room, Power, Electronic, 808/909, Jazz, Brush, and Orchestral. MIDI Output: Send MIDI to other apps or external devices. Configure MIDI channel (1-16), program change (0-127), and destination. Works with Virtual MIDI and MIDI Network Session. Can be used simultaneously with the built-in sound engine. Keyboard Support: Use the on-screen software keyboard, or connect a Bluetooth/USB hardware keyboard for a real typing experience. Supports Japanese input with proper IME handling. MIDI Network Session: Connect to Mac or other iOS devices over Wi-Fi to control CoreMIDI-compatible sound generators remotely. Dark Mode & Rotation: Full support for light and dark modes. Works in portrait and landscape orientations on both iPhone and iPad. Note: Playback stops when the app goes to background. Using the Built-in Sound: Simply launch MIDIWriter and start typing. Each key produces a unique sound based on its character code. Enable drum mode in Settings for percussion sounds. Using with External MIDI Apps (Virtual MIDI): 1. Open a CoreMIDI sound generator app. 2. In MIDIWriter Settings, turn on "MIDI Output" and select the destination. 3. Type any key to hear sound from the external app. Using with Mac (MIDI Network Session): 1. Connect iPhone and Mac to the same Wi-Fi network. 2. Open MIDIWriter on iPhone. 3. On Mac, open "Audio MIDI Setup" and configure Network MIDI. 4. Connect your iPhone to the session. 5. Open a CoreMIDI app on Mac and select the network session as MIDI input. 6. Type on MIDIWriter to play sounds on Mac. Credits: Built-in sound engine uses "GeneralUser GS" SoundFont by S. Christian Collins. https://schristiancollins.com/generaluser.php

Voxomat adds a unique human-meets-machine character to your tracks. It transforms simple basslines into talkative, morphing sequences, while offering endless possibilities for non-pitched sounds like drums. Higher-pitched inputs can trigger complex harmonic shaping effects – the resulting inharmonic textures and FM-style intermodulation deliver a grit typical of Lo-Fi aesthetics. Conversely, these frequency modulation effects can also be smoothed out by using harmonically dense inputs, such as overdriven tones or overtone-rich sawtooth-based sounds. Using the plugin's modulation options in parallel opens wider sonic possibilities – for example, adding powerful chiptune effects to any source or mimicking the aggressive, harmonically shifting "tearing" sound of hard-synced oscillators. Based on the Ringotron engine, Voxomat utilizes a hybrid modulation architecture combining audio-rate modulation with resonators. FEATURES: • Complex rhythmic movement driven by an array of synced LFOs for deep, malleable modulation • Integrated envelope follower for responsive modulation • Touchscreen-friendly modulation sequencer for pitch FX control • Powerful resonant vocalizer for synth basses and all overtone-rich bass timbres • On unpitched inputs like drums, effects range from whispers to glottal textures and stronger vocal glitches • For pitched inputs, higher registers can more easily uncover robotic qualities as complex frequency relationships yield unique, inharmonic textures • The user interface is designed to blend algorithmic automation with tactile control, turning the effect into a responsive performance tool • Each preset features a set of primary performance controls pre-mapped for automation and expressive live play PLEASE NOTE: • An AUv3-compatible host is required to use this app • The plugin is designed as an audio processor and is not a MIDI note event processor or sequencer in its current form • Suported sampling rates: 44.1, 48, 96 kHz
