Isotope MIDI Keyboard vs FrequencyCat

Isotope is an isomorphic MIDI keyboard app for iOS. Isotope makes playing music fun and intuitive, while also making music theory more accessible. Unlike traditional keyboard, Isotope's isomorphic grid layout is based on mathematical and geometrical properties of sound itself. When you play it, it's much more intuitive. When you want to learn about music, it shows how notes relate to one another. # Isomorphic Keyboard - If the interval stays the same, the form of your hand stays the same. For instance, when you put your first finger on the C, third finger on the E and the second finger on the G, it's the C major chord. Now that your fingers are in a triangle, if you just go up by one row, now it becomes the F major chord. - Square-based isomorphic keyboards like Isotope resembles stringed instruments tuned in perfect 4th apart from one string to the next. Therefore, if you have an experience in playing stringed instruments like the guitar, the bass, the violin, or the cello, you will get learn to play Isotope quickly. # Element - Built-in Sound Engine for Isotope - Available as an Audio Unit v3 plugin - Element has a versatile sound characteristics resembles double bass and bass guitars in the lower range, electric piano in the mid range and woodwind in the higher frequency range. # Connectivity - Supports MIDI (Garageband, Drambo, FL Studio Mobile etcs.) - MIDI over Bluetooth (For connecting Isotope to your computers / or any other devices that support MIDI over Bluetooth) # Usability - Multi-window and Slide Over support on iPadOS - Velocity based on touch area and accelerometer - 3rd party Audio Unit instrument plugins # Customizability - Row Interval adjustment - Fully customizable themes - Resizable buttons / app windows

Hide an image inside sound. FrequencyCat is a playful tool for exploring the connection between images, sound, and spectrograms. Choose an image, and FrequencyCat transforms it into a unique audio signal. Play the sound and view its spectrogram, and you’ll see the original image emerge again from the frequencies. With FrequencyCat, you can: - Turn images into sound - View audio spectrograms in real time - Play sounds and reveal the images hidden inside them - Explore how different images create different sounds - Discover the relationship between sound, frequency, and Fourier transforms in an intuitive way There’s no magic behind it. Just frequencies, phases, an inverse Fourier transform, and a little curiosity about sound. Whether you’re interested in acoustics, music, signal processing, or simply wondering what an image might sound like, FrequencyCat gives you a new way to explore. Pick an image. Hear what it sounds like.
