Carnatic Keys is a musical instrument catering to Indian Classical Music. It takes the familiar piano/keyboard interface and transforms it to play Carnatic Swaras and Ragas. Carnatic Keys helps enthusiasts of Indian Classical Music have fun playing and expressing themselves using Carnatic Swaras and notations. Additionally it acts as a Raga guide. It helps to bridge the divide between Carnatic and Western notations and concepts. Users now have a tool that lets them express themselves using Carnatic vocabulary. Hindustani Music lovers can also benefit from this app because there is a lot of commonality between the two systems! In Carnatic Music, an octave is divided into 7 notes or Swaras - Shadjam (Sa), Rishabam (Ri), Gāndāram (Ga), Madhyamam (Ma), Panchamam (Pa), Daivatam (Da) and Nishādam (Ni) . Sa and Pa are fixed in the scale, while the other Swaras can each have different variations or types for a total of 16 Swaras - Ri (3), Ga (3), Ma (2), Da (3) and Ni (3) - with overlaps to fit within the 12 notes of an octave. The songs we learn in Carnatic music are taught using Carnatic Swaras. Carnatic Keys, therefore, makes it easy for you to play these songs and musical exercises. If you know your Swaras, you can now play them easily! But Carnatic Keys takes it a step further by acting as a Raga guide as well! A Raga is a melodic framework unique to Indian Classical Music that evokes different moods and feelings. Each Raga consists of a set of Swaras of selected types or variations. For example, the Raga Hamsadvani has “Sa, Ri2, Ga3, Pa, Ni3, Sa” as its ārohanam (ascending scale) and “Sa, Ni3, Pa, Ga3, Ri2, Sa” as its avarohanam (descending scale). Using the Swara Selector, you can select Swara variations of the Raga you would like to play. The Keyboard Display selector toggles between various display modes - showing all Swaras, the selected Raga Swaras, or Western notes. This will help you focus on the Raga at hand by removing other Swaras from your focus. You can further disable all non-Raga keys by toggling the Raga Mode button. You can now avoid hitting the wrong keys and stay in tune! Carnatic Keys also supports the concept of Gamaka or ornamentation. Gamakas involve graceful and smooth variations in the pitch of a note, using oscillations or glides between notes to add emphasis and character to each Raga’s individuality. A smooth pitch wheel allows for seamless Gamakas, up or down 5 semitones or more! Getting good Gamaka takes a lot of practice, so feel free to skip Gamakas and any pitch-bending as you start out, and slowly start to experiment with them! Carnatic Keys come with 6 different instrument choices - 2 types of Piano, Harp, Guitar, Flute and Sitar. It also comes with 3 different Demo pieces of familiar Carnatic songs. You can enjoy listening to these while you are taking a break or just want some inspiration! Here are some more features of Carnatic Keys: ◆ Multi-touch keyboard ◆ Supported in both portrait and landscape mode. Landscape mode takes advantage of the increased width to show more keys. The keyboard is thoughtfully laid out to show about a half-octave below and above the main octave you can hit lower and higher notes with ease. ◆ Optimized separately for iPad and iPhone to take advantage of different screen sizes and formats ◆ Choose between Light and Dark Modes Practice (or play!) basic lessons like Swarali Varisaigal, Jantai Varisaigal, Dhattu Varisaigal, etc. or venture into Geethams, Swarajathis, Varnams, Keertanams and more! Have fun playing and experimenting, all the while thinking in Carnatic Swaras and Ragas!

Zodiak Taurus is not your grandparents' octavizer. Zodiak Taurus is a mammoth multi-voice beast that takes the puniest tone and turns it into full frontal sonic assault. Slap it on your guitars, drums, bass, vocals, or even your keyboards. Then let Taurus elevate your sound. Taurus generates five independent voices — or reconstructions — of your input signal in realtime. These voices together span a whopping five octaves. With a few tweaks, you can double track your guitar, add a bass, a sub bass, and even a high frequency overtone. The result is a big, spacious sound that covers the whole stereo field. But that’s only the beginning, because this is a Zodiak effect. To sweeten the pot, each Taurus voice features its very own saturation stage (tuned specifically for it); a detune control for obtaining non-octave intervals or even natural chorus or ADT effects; a regenerative delay stage that can be used for staggering the voices, changing their timbre, or even causing them to self oscillate; an attack envelope that can have each voice fade in at different rates; a tuned EQ submodule, as well as stereo panning and other parameters — all collected in a familiar mixer-like interface. Newly developed algorithms deliver crystal clear signal reconstruction, and operate so efficiently that Taurus is as responsive when playing live as it is well-behaved in the studio. A special post-FX module includes cabinet simulators, room emulation, variable EQ, and compression to produce an easy to use, all-in-one audio solution. Zodiak Taurus also works as an AUv3 effects plugin on your iPad, iPhone, and Silicon Mac computer. It comes with over 60 factory presets to start you off in your journey, as well as many other advanced features like patch save/share, MIDI learn, and more. The latest offering in Yonac’s new Zodiak series of effects, Taurus is jam packed with sonic easter eggs. Whether your goal is to emulate diverse instruments, create enormous walls of sound, or paint complexly layered psychedelic soundscapes, Taurus has a roadmap for you somewhere across its controls.
