thank you, Chas. Actually, as Zuki entitled the topic "Full Circle", I feel that my message lies upon the subject, because what I'm experiencing now is distancing from my usual routine while questioning it myself. I hoped that buying SX900 would give me inspiration as it happened when I got previous keyboards, but it didn't happen, although now being away I miss something of my SX900. Certainly it didn't help that after 1 month of playing the keys started to produce noise, I had to get it to a service, and the service was incompetent, so the grease they used gave only a temporary fix, and then I decided to leave Russia (temporary, I hope), thus so far my story about SX900 isn't a happy one :-)
And the music you hear in my video is something I'm learning myself, I don't have any formal training, and I used to think that this kind of work wasn't my cup of tea, that everything shoud be created on the fly, and this approach reminds a lot of an office job. But now I'm thinking maybe it's not a bad thing - an office job. Well, this is me getting older :-)
I think people with really powerful computers don't experience problems with latency, otherwise we wouldn't have so many piano libraries; but I'm yet to check it myself. Some time ago I would've replied to your question with certainty saying that hardware instruments were definately my way to deal with music. Maybe now I feel more like to create music step-by-step, so what felt wrong before now feels okay, and what was exciting in the past, today isn't so much...
But I have to consider that due to the economics I never had a chance to get an instrument of a higher scale, like Tyros, or Genos, or PA4X; maybe if I had all the up-to-date upgrades I would've felt differently by now, but it's not a perfect world; I'm sure that with today's prices for TOTL keyboards people all over the world feel that they are being extorted.
