Hi there!

Is there any difference on multiplexer pins, so long u use inputs 1,2,4,5,12,13,14,15, and change physical jack inputs in corect order.

No difference, you only need to keep in mind that all odd/even inputs, except first two, can be treated as a dual zone input so they should go one after another.

Thanks guys. Yes it has to be synthex version with 4 4051 .And i have only 2 cheapo alesis pads, and did i mention i cant play drums? I just love the idea building things yourself. You choose if you wanna put 32 3,5mm inputs for 5$, or 32 neutrix xlr 20$ each. And if you wanna put it in shoe box . I put analog and digital board together and connected internaly. Great work guys. Dmitri and all of you.

If you don't play drums, you can do many other projects even more funny !

You right. I thought i could upgrade preamps on my Yamaha AW4416, but this is little easier, if you know what i mean. . I can play hi hat, overdub kick and snare and it still sounds better then programmed. I have song which need some megadrums, i will post it one day, you'll get your chance. I just hope it will be free
