I also enjoyed the video of you playing your FA. The pianos are definitely different that Yamaha.
I guess you mean DS, as I never had FA :-)
I have the Sweetwater pen that came it)
To tell the truth this is a very difficult sentence for a foreigner to get :-)
I'm thinking now that when there's an option to change one keyboard to another without too much fuss, each keyboard stays in constant competition against all of the others, in other words, there's a lot of room for second guessing; so it's not a trouble if the process is fun for you, but I imagine that there's still some fuss to deal with and that you actually plan to focus on playing it rather then changing it.
The thing is with the most of products that they are intentionally desinged with certain flaws so that there will be motivation to get a more expensive one. In my youth I had to buy certain models because of financial limitations... Well, this is still the case. But when you are young and it is all new to you, it is easy to compromise because you are focused on these new things; when I got PSR-3000 it sounded so different from my previous keyboard, that certainly was mesmerizing, and it was this way with each keyboard before, but not that much with each keyboard after. I think after that there are two options. On of them is to accept that excitement is no longer connected with getting new product, which we can consider as some sort of emancipation. Another option is going to the premium sector, if you can afford it. I currently can't. In case with home pianos, that would be some of TOTL home pianos from Yamaha or Roland... In the same time, we are talking about digital instruments, so they are more or less reasonably priced - it's not art or luxury.
Well, I would hate to influence your decisions when it comes to financial matters, in the same time this is what we do, we talk; and choosing not to say something is also sort of influence.
I'm biased right now for some personal reasons, but speaking my mind, I see two reasons why it's justified to buy some middle-of-the-line instrument: when you are not sure that you are going to play at all (not everyone actually plays), or if it's financially impossible to buy a TOTL, for example, Genos now costs in Russia about 500.000 rubles, while an average income is 25.000 per month, and half of it goes for food, and about 10.000 goes for paying the bills. A lot of people in the world live like that, and that's the reason why actually have decent instruments for $300. But we understand that this is still abnormal, people here understand that a proper paycheck starts at 150.000 rubles, not 25.000 rubles.
Well, you see, something bothers me... it's a night time here; see you later ! :-)
