Is it Overspill?

[EricSinger]

I soldered all the jacks inputs of the megadrum

I connect the connector 40 ways on the synthex board.

The vumeter is normal, there aren't something anormal.

But when i connect a pad the vumeters of the pad that I connect start to move up and down, the midi led is on and i don't touch any pad.

With these pads I can normally play with alesis DM5

I tryed with MAX and 74hc.

what happened to my megadrum??

Something the vumeter don't move and I touch a pad and the vumeter moves in 4 or 5 channels with both IC (Max and 74hc)

I'm desesperated and i'm going crazy hehe.

thanks

What sort of cable do you use ?
How did you connect the ground ?

[EricSinger]

thanks synthex I resolve my problem minutes ago.

I use to connect pads a bus of jack cables with colours from Millenium MPS300. I remplace this cables for many jack mono cables and the problem resolved.

Anyone use this bus of jack cables!!

Thanks

[Synthex]

Great !!

[EricSinger]

YES

synthex can you find an explication to this problem?? interferences between cables?

[Synthex]

It must be interferences between cables and poor ground.

[EricSinger]

why in my alesis dm5 this cable works perfect??

[Synthex]

Is there trigger Input attenuator on your alesis dm5 module ?

[EricSinger]

I don't know, I never open the rack of my alesis
