The app UI would be much clearer and easier to navigate with a horizontal iconic audio chain. Selecting audio chain elements could display a vertical list of settings. I would recommend doing some competitive research with the Valeton GP-5. Clean, simple UI that is easy to navigate. I would also add a feature from the Spark2 app UI of swipe up/down on audio chain elements to toggle on/off. A hardware feature that I also find missing on the NC is a minimal LED screen that shows the current preset name. Should be able to navigate presets without using the app, which requires confirming current preset. Also could include a drum machine and metronome.
Please use the feature request for one feature at a time. Thanks!
