Meet Aimée, your AI assistant composer, ready to help you create amazing music effortlessly. Aimée: Originality You Can Trust. In the evolving landscape of artificial intelligence and creativity, concerns about originality and copyright are paramount. Aimée, the AI-powered assistant in YouCompose, stands out by ensuring that the music she helps you create is entirely original and free from copyright issues. Aimée Doesn't Steal! Aimée's AI isn't trained on existing musical data. Instead, she generates her own unique musical content. This innovation is achieved through the clever use of an expert system that combines music theory with advanced genetic algorithms. As a result, Aimée produces truly original compositions that are not based on or derived from existing works. At the heart of Aimée's originality is an expert system grounded in comprehensive musical theoretical data. This system provides Aimée with a deep understanding of music, enabling her to compose with creativity and precision. Whether you're crafting a symphony or a simple melody, Aimée applies her theoretical knowledge to ensure your music is harmonically rich and structurally sound. Aimée also leverages genetic algorithms, which allow her to evolve and refine musical ideas through a process akin to natural selection. By iteratively improving upon initial ideas, Aimée can explore a vast space of musical possibilities, generating compositions that are both innovative and musically coherent. This approach is crucial in addressing potential copyright infringements. By not relying on pre-existing musical data, Aimée ensures that the music you create with her assistance is genuinely yours. Why Originality Matters? In the realm of music composition, originality is not just a matter of artistic integrity but also a legal necessity. Copyright infringement can lead to significant legal challenges and financial liabilities. Aimée's ability to create original music provides peace of mind, allowing you to focus on your creative process without worrying about potential legal repercussions.

Your voice. A different character. MORF is an ivlt.io Gadget for exploring live voice and sound transformation on iPhone and iPad. Choose a sound, set your input level and shape the result with controls made for playing. Two Audio Unit (AUv3) plugins bring MORF into your host app. SHAPE YOUR SOUND Adjust pitch and blend your original input with the transformed sound. Open the shaping controls for tone, body, drive, space, movement and formant. Map real-time controls to a MIDI controller with MIDI learn. CHOOSE YOUR TRADE-OFF Choose from the processing modes available for each model. Faster response and greater detail make different demands on your device. Estimated delay ranges help you decide; actual latency also depends on the model, device and audio connection. Not every model supports every mode. USE MORF IN YOUR HOST APP MORF includes two AUv3 effects, with no separate purchase or download. ivlT: MORF is for live use: monitoring and playing through it with headphones. It runs the Fast engine, plays the sounds that have a Fast version and reports about 41 ms of latency to the host. ivlT: MORF Studio is for recorded tracks and exports. It runs Standard or High Quality and plays every sound in your library. It reports about 0.81 s (Standard) or 1.01 s (High Quality), so it is not for live monitoring. The host's delay compensation lines up the converted track on playback and in exports, and exports render offline. Both plugins use the sounds in your MORF library; add new sounds in the app and they appear in the plugins automatically. Pitch, Mix, Input, Gate, Output and the shaping dials are host parameters, so hosts can automate them. An input-keyed gate mutes the converted voice while your input is quiet; some sounds would otherwise turn room noise into artifacts. The plugins process audio on your device and make no network requests. Use one MORF Studio per host session; live MORF instances can run alongside. Latency figures are what the plugins report to the host at 48 kHz with 256-frame buffers, not microphone-to-speaker measurements. The plugins are tested on iPad in AUM and GarageBand; other hosts and iPhone are not yet tested. BUILD YOUR LIBRARY Start offline with Clara, Cello, Violin, Bird, Whale and Storm, included in the app. Preview optional sound packs before downloading. Import compatible models saved in Files. Download external models separately in your browser and transfer them to your device before importing. Supported imports include RVC v2 pitch-conditioned models at 32, 40 and 48 kHz; arbitrary AI models are not compatible. Create personal sounds from recordings on your device. Organise your library with drag and drop, and remove downloaded models when you no longer need them. PROCESS ON YOUR DEVICE Audio transformation runs locally. Microphone audio is not uploaded for cloud processing. Internet access is needed for the ivlt catalogue and downloads; installed sounds can be used offline. Optional downloads require additional storage. PLAY RESPONSIBLY Use recordings and voice models only with the permissions and licences you need. Do not impersonate others or mislead listeners. A model being publicly downloadable does not mean it is cleared for commercial use. For live monitoring, use headphones or a suitable audio interface to avoid feedback. Wired audio is recommended; Bluetooth adds delay. Sound quality varies with the source, model and processing mode. MORF is a creative sound tool, not a guarantee of an indistinguishable voice replica.

Verdict
The clearest difference is update cadence: MORF at every 2 weeks against YouCompose's every 4 months. MORF also leads on price ($9.99 vs $12.99). YouCompose's advantage is device support (4 vs 2) and iOS requirement (14.0 vs 18.0). On ads and in-app purchases there is nothing between them.
