Yocto v2 test mode - R688

Hi,

in the manual there is the guide to only solder sequencer parts which are needed to trigger test pulses. In the manual there are the places highlighted. What is with R688 below the ATMEGA? How should it be soldered or what is the right approach? I am afraid to forget a piece which could harm my yocto.

Cheers Ingo

I just built the whole sequencer section. I literally went through the voices part list section by section. In each section just do resistors, then diodes, etc. Ended up working great. I did have to adjust TM2 to 200k and make the Cowbell mods mentioned in the Yocto1 "useful building tips" thread.

For R688 I just put it on the opposite side of the PCB. You can also cut the piece on the socket but didn't seem necessary to me. You can also get a milled socket which don't seem to have that middle bridge on the socket. But it seemed simplest to just put on the "button side" of the PCB.
