Interesting Effect App

Grafik wurde überarbeitet und eine Random Funktion hinzugefügt. Spitze.
Wenn es machbar wäre noch ein Button um den Input bei der Ausgabe zu Mute’n, damit nur das Granulierte Ergebnis zu hören ist, dann wäre ich happy.
Und wie wäre es noch mit einem Shimmer FX in GRFX?

Response from developer

Vielen Dank für dein Feedback! Wir werden deine Anregungen auf jeden Fall berücksichtigen. Die Verbesserung der Sichtbarkeit von Schaltflächen ist etwas, an dem wir ständig arbeiten, und eine Randomizer-Funktion für die Tonleiter in GRFX ist eine interessante Idee – wir werden sie für zukünftige Updates in Betracht ziehen.

Very good

It's really good, even extremely well-made as a plugin, even if it consumes a lot of CPU. Thank you, it's a good product!

Response from developer

Thanks so much for this! Really glad GRFX is delivering for you sound-wise. The CPU usage is fair feedback, definitely something we keep an eye on for future updates. Appreciate you taking the time to write this 🙏

Doesn’t Work On iPhone 12

Update: No support response. More wasted money on an Apple app. No more.

No sound. Control labels are too small and this is another developer that doesn’t know how to make ‘white’ labels, only using half the pixels so they’re dingy gray adding more difficulty reading them. No ‘in app’ documentation. No PDF manual. App doesn’t follow online documentation. Et cetera, et cetera, et cetera. Wasted $8. I haven’t bought an Apple app in a very long time for too many negative experiences during these Tim Cook years. I chance it here and get burned again. You folks forgot the sound. Dahh

Response from developer

Thank you for your review. Please bear in mind that GRFX is an effects app, so it doesn’t produce sound on its own. If you’re using the standalone version, the app starts muted to avoid feedback. To enable it, you’ll need to toggle the button in the top-right corner of the Mixer panel (this may be why you weren’t hearing any sound). Could you please clarify what you mean by “the app doesn’t follow the online documentation”? Did you find any information missing or unclear in the manual? The label colors were a design decision, but if you’d like to suggest improvements, feel free to reach out through our website. We’re always happy to listen and take note. Many features and fixes in our apps come directly from user feedback. Lastly, could you please check whether enabling the Mixer panel resolves the sound issue you were experiencing? Best regards
