I also work a lot, have a newborn, wife and family that takes time. Also the time I started midiboxing I had a lot of gigs and practice with the band 10h a week.
Still, I wanted to have a midibox sid.
I took a trip to the forum and it had taken me half a day of wait to know what I needed to build what I wanted...
I ordered in about half of what I needed from smashtv and I solder when I had the time. I'm not finished yet, and I do it in a slow pace when I for time for it. Though it is not for free it is still pretty cheap, and that was what dragged me the most towards this - the freedom to do it whenever I have time, money and in my own pace.
It is way possible to build a sid without learning the details. Not all have time for all the details, but mb platform is for almost everyone. And the soldering stuff, it is really not hard at all. There is a few tricks need to knows, but there are plenty of vids on utube that show how it is done and how it should look like.
And then you have the sammichsid... It is so easy to build, and its the closest to a complete solution u get for now.
I believe if u are a musician and know how to wire ur instruments, you will probably be able to do this too without very much effort.
As for sids, from time to time they are sold in the midibox fleamarket, and also on ebay. Not very hard to get, you just need to do a search now and then. It has taken me approx. 10th searches to get my sids. Some bought on fleamarket and some on ebay. You only need one or two, but you can use up to 8 in the 6582. I now have 8 of them, and that took me about 6 months.
And that also in a country it is nearly impossible to dig up commodores.
Everything, I believe, can be done, but in right time and with the priorities right. If u want to do something, u go ahead and make time for it. There are very few people in the world with that little time. Many of us in here are active musicians, and have time.
Don't mean to flame you in any way here, just suggesting and encourageing you to get going.
You will meet people here more than willing to help out in any way they can, and it is no talk of they don't want to be bothered wit it, help needed, help u will get. This community is composed by a lot of different people with lots of different skills. And are very welcoming to newbies.
So if you really want a midibox sid, here is the absolutely best place to be. Some sell their midiboxes in the fleamarket, and it just cost time to check now and then if you really think u cannot build one yourself, wich I believe is a very real possibility that you can do...
Good luck, stick around and see what happens here and what u can do and you might find urself doing less gigs and building midiboxes instead.
Haz a nice day.
