[sdiy] SIP filter modules coming

[Roman Sowa]

I don't think that matters at all for repairability. First of all no big 
manufacturer will ever accept subassemblies, because they are more 
troublesome to mount, and they can do it better themselves and probably 
cheaper too, by placing bare components (like 3320 in this case) on 
their PCB directly.
This is rather destined for home DIYers and small boutique makers, to 
make their life easier. One reason for making this hybrid was "we heard 
some people have trouble soldering QFN". So there you go. Easy to use, 
instant gratification.

Also, it's not rocket science to re-make such a module, and anybody with 
access to basic technology and common services can make/order something 
like that or better. See how many Juno voice clones there are or other 
subassemblies. It's not a dead end for a synth to contain custom parts, 
but an oportunity for small businesses in 20 years to make replacements.

Yet another thing - be it custom potted module, or basic discrete 
design, none of that guarantees replacement parts in 20 or 40 years. I 
wouldn't be surprised to see 0201 to 0603 adapetrs sold in DIY stores in 
the future to save old synths, while noone will make those large 0603 
resistors any more.
