Yes indeed. You can imagine the following:
- 1 push on wave button: highlight wave selection (selection mode)
- another push on wave button: cancel selection mode
When in selection mode:
Turn rotary knob to go through waves without modifying the current one (wave plot having another colour to show selection mode active)
Confirm your choice by pushing the rotary knob..
Exactly. For the Wave.
For others, like frequency, a small variant:
- 1 push on freq button: highlight freq selection (selection-follow mode)
- another push on freq button: different color highlight (selection-confirm mode)
- yet another push on freq button: cancel selection mode, no more highlight.
When in selection-follow mode:
- Turn rotary knob to go through frequencies *with* modifying the frequency,
- As the frequency is set automatically, it stays the normal color
When in selection-confirm mode:
- Turn rotary knob to go through frequencies *without* modifying the current one
- As the frequency is not set, it stays the special UNSET color
- Confirm your choice by pushing the rotary knob, now color returns to the SET color, until you turn the rotary again.
- Canceling your choice (by pressing freq button again, while color is the UNSET color, displays the original frequency and non-highlighted color
So while we have 2 modes for frequency (follow and confirm) and analogue the wave has only one mode (confirm), I would argue for frequency the follow mode is the first one, whereas for wave the confirm mode is the first (and actually only) one.
Amplitude and Offset may also have similar follow and confirm modes, so you can either jump from one to the other, or walk to it.
