After reading this thread and thinking about it for some days, I just decided to give my 2 cents...
I do not really have problems with money. Meanwhile I could easily go out and finally buy me a Prophet 5 and OB-X8 without having to think about it very much, because there would still be enough money left to have a good safety net below me. But if I ask myself why I just don't do it, most of the arguments here come to my mind:
1. The "What if?" thing. Even if you do not exactly have money problems, it seems to trouble some people. I'm married and have an eight month old daughter. What if she got serious medical problems and my wife can not handle it all alone. That said, my wife does not work at the moment. I'm producing all the income. What if I had to reduce working hours to support her? We are living in a big house, that needs a lot of money to get it warm in there. We need cars to get out of our very small village. We could survive with only half of my income... but is "surviving" what we want? We don't want to change our standards, to be honest. The more things you have, the more money you need to keep everything fine and running. So the safety buffer should be a lot bigger, than what I would need, if I were living alone in a tiny flat. Bets are good, that nothing bad will happen and I will not need so much money. But if you are an overly thoughtful person, you can not simply move aside the "What if" question. It will just pop out everytime you are planning to buy something. Another thing that troubles a lot of minds at the moment: We are living in Germany... and when I'm hearing in the news that our government just decided to send Leopard 2 tanks to Ukraine, which is not sooo far away, I must admit, that we are living in fear of war in our country, too. What if that happens? Better have a lot of money to take the next flight to some remote island with the whole family. Bets are good, that will not happen, too, if Putin does not want to have the whole NATO directly at war with him... but it's still possible.
2. Moving all the overly anxious things aside, there is still the "What for?" thing. At the moment I do not really have time to really use all my gear. Besides my Kronos and Rev2 that I use for gigging in a cover band, all my gear is standing here unused. I'm thinking on selling all these things, too. Selling stuff for not using it and buying an P5/OB-X8 is a big contradiction, so there will be no new toys for me, until I really got the time and interest of really "using" it, not just "having" it. When I come home from work, there is this super sweet little daughter waiting for me and I just cannot go to my synth without having bad conscience, knowing the little wants to play with her daddy, that she didn't see the whole day. Priorities. I will not get back the time with her, if I just let it go. So perhaps I let the synth go, until she is old enough to be happy about "not seeing her father" in (hopefully) 18 years ;-) I can buy some new synth then.
3. When I'm actually making music at home at the moment, I play the piano and electric "pipe" organ a lot. Preparing my pipe organ stuff for sundays and playing classical piano, just for myself and to not lose my skills. That's the minimum I have to do, and the maximum a I can do at the moment. I'm doing the piano stuff on my wife's epiano at the moment. It's a nice one, but even the best epiano can not replace the cheapest real piano. My real piano is still at my parents house. I never took it from there, so there is a piano there, when I'm visiting them. For the reasons above I think about buying a grand piano at the moment. Yes, that would be really a lot of money to spend. But that would be an instrument for life and a life-long dream come true. I could play it without electricity, if we really get problems with blackouts caused by this shitty war. And I would be actually using it, instead of just looking at it. Selling all my stuff would help a little bit in that direction. I cannot buy or house a Steinway D, but a brand new Yamaha CX2/3 baby grand could be actually be the way to go for me. My wife can play it, too, which is good for the wife-acceptance-factor and my baby seems to love when I play piano. Hopefully she will get interested in this versatile instrument, when she is some years old. A real family instrument. Yes, I could not take it with me, to the remote island in case of emergency, but since is the absolut worst case scenario I would take the risk ;-) There would still be a buffer left...
So my problems are not really comparable to yours, Lobo, but the thoughts they imply are similar. I would never sell everything I have. Sell a lot, but not all. Without music, without me. I can live with not being a creative musician writing my own music. I'm perfectly fine with playing things others wrote on a instrument where I can not program my own sounds, but live with the one and only default piano patch ;-). But I can not image that there will be a time where no music is played in this house at all... it's the most beatiful thing on earth and so important to everyone, even if they do not recognize it.
I wish you all the best and am really excited to see what direction you will choose. If we actually get to know it, since you surely would quit this forum, too. Which would be a bummer...
