One thing you seem to overlook is that this is a portable studio which Gina stated was optimum for engineering a live performance. Using band players, vocalists and maybe some electronic musicians who are performing on stage and require a live mix to be done. What she has presented is a fantastic application of both hardware and software for this purpose. It's not designed to be a production suite. But everything she has put forward here replaces a 16 channel (or more) mixing desk, an FX control rack, a synthesiser rack, DAT or other tape recording device.
In response your argument about assigning a midi controller to change volume, I have to say that this is just stupid. Firstly, if I'm on a keyboard with only 16 assignable controllers, I am not going to waste one of them on a volume control. I'd use it for something more valuable (like cutoff or resonance or some synth control). I don't know any musician who would waste one on volume. In fact, I don't know any musician who would want to change the volume of their channels while they are playing. If they want to change the intensity of their notes, they will play them softer or harder on the keys... That's velocity mate... use it. Secondly, Gina made it pretty clear that this application was for engineering a live performance, either solo or with a band. If I was doing such a thing, I wouldn't use a fader to change the level of one of my parts. I'd just use the mouse because it saves my controllers (as stated) and also because it's not like I am going to be majorly changing the volume during performance. I would have set my levels during sound check and to do this, mouse would be sufficient anyway. After the sound check, I would only make minor changes throughout the performance as required.
It's a great article because it pretty much agrees with any producer or engineer I have discussed this with has recommended for a laptop system. Though there are some softwares and hardwares that she hasn't mentioned, I can still see how they would relate to and function in a setup like this. Gina made quite clear from the outset that this wasn't an article telling you what you should use. She was sharing her own application with us to give us an idea. The message I got from her article was "Take what you want from this setup and incorporate it with your own rig".
And you are a disgruntled PC user that obviously has a serious issue with Macs. You've provided no constructive feedback or arguments to support your opinion. All you've done is nitpick the author's comments and even down to her internet browsing methods.
Gina is not asking you to conform to her application. You're talking about something creative here. If you were really involved in this artform you wouldn't be debating her points so much. Artists collaborate and support each other. They give each other advice and guidance when required and they work together. Sorry mate, but no matter what arguments you present, you will not prove your point of view is right. The application this article discusses is brilliant for collaboration, both with technical and non-technical users...
Oh, and thanks for the article, it's been very helpful.
