The first two have already been mentioned in other posts.
The third one I haven’t seen mentioned but it would definitely be helpful.
BTW, for non Spanish speakers and those without access to Google Translate, the third request is for a tone generator that can output sine wave tones, white noise, and pink noise.
The first two are the ability to route Aux outputs to different outputs like Matrix, Main, etc. and being able solo channels to the headphone outputs (I think).
