4 - MIDI IN PCB ERROR

We have noticed a small problem on the midi board, pin 2 from the midi

in port is connected to ground and under certain circumstances this can

lead to a buzz/hum when midi in is connected. Paul is going to update

the build docs, here are photos of two possible ways how to ﬁx it (not

soldering pin 2 might be suﬃcient if it doesn't touch the pad):

1. Use a dremel or round ﬁle to remove the pad/increase the diameter of

the hole to make sure pin 2 isn't connected to gnd or clip/remove

pin 2 from the midi socket before soldering it

2. if you have already built the midi board and don't want to desolder

the socket, cut a trace at 2 points and use a jumper to connect ground

to pin 17 of the connector

SUGGESTED:

desolder the midi socket, lift (or cut) and isolate pin 2

and solder again.

RE-909 service advisory 15-12-20

We found a minor error in the snare drum that didn't come up in testing. Its a simple ﬁx with a single patch wire, please

download v.1.7 build documentation for details.
