Ni-Ga is correct, Ni-Di is correct, Ni-Ke is correct. And there is Ni-Zo. Maybe you should use tempered clavier intervals (B flat and B sharp), to get more correct intervals. Or, make intervals adaptable. ### 4/5 — George D. *2024-11-09* Nice, full natural voices. I have a problem with the right-side note buttons not appearing on my iPhone screen. What’s the solution? No fix available yet. **Developer response:** thanks you for feedback, it will be fixed in the next release. ### 2/5 — Adjust Only Vou… How? *2024-01-13* Is it actually possible to adjust pitches independently? Because I don’t see how. ### 5/5 — ✨thank you!✨✨ *2024-01-12* this app is holy. ### 5/5 — Great app; one issue *2023-12-09* Thank you so much for providing this ison app. It is quite excellent. The "Natural vocals with bass" is my preferred setting. I love that I can use the Pitch slider while the pitch is still playing. Some ison apps can't do that. I need that to match the pitch that another chanter has started. I also love that you have the lower Dhi, Ke, Zw flat, and Zw. available. Again other apps don't provide that and your setup and the best one in this regard, One issue I noticed though isthat, when going from 0 to -12 on the pitch slider, it doesn't get me "down" a whole (western) step, as I expected; rather, to accomplish that with this app, I have to go to about -20. Have you noticed this (or done this on purpose) and would you consider applying a fix to make 12 units equal to a whole step? Thanks for your consideration. **Developer response:** thanks for feedback, this will be addressed in the next release. ### 4/5 — George D. *2023-11-18* Nice, full natural voices. I have a problem with the right-side note buttons not appearing on my iPhone screen. What’s the solution? **Developer response:** thanks you for feedback, it will be fixed in the next release. ### 5/5 — Good start, more functionality needed *2022-09-17* I love the quality so far and it’s sorely needed. I would hope the developer could add Split View support and other such features that make ease of use and functionality more widespread. For example, being able to turn it in landscape view, close the window without eliminating the app from working, etc. I’d gladly pay a few bucks to help support these features. Keep up the good work! **Developer response:** Thank you for feedback, will definitely add them in future versions. ### 5/5 — Good app for free *2022-09-16* The quality of the ison sound is good, the layout is straightforward and easy to use, and it’s not bogged down in unnecessary design features. For a free app, it’s excellent for what it is. ## Frequently asked questions about Byzantine Ison ### What is Byzantine Ison?
