As was mentioned, by default there's no attenuation on either of the sum outputs of the Sum/diff, you can set this with jumpers.
I'm not buying a maths though, not my idea of fun...

Okay, so the /2 that LRMSMSLR is doing on the second stage is just the 6db gain reduction. I guess I don't really understand how dB measurements work, since I expected the math there to be (C+D)-(whatever 6dB translates to in voltage), rather than (C+D)/2.

Exactly. -6dB is the same as dividing by 2 in voltage terms, +6dB is a doubling of voltage.

Hi, the -6dB stage is actually in the first section rather than the second, there was an error in the first version of the manual that made it look like it was the other way round but it's fixed now. :tu:

Sorry if this is a dumb question, but is a cv adder the same thing as a precision adder? If not, could it be used as one if you put a quantizer after it?

Is the adder precise enough for pitch CV?

Yes the sumdif uses 0,1% precision resistors to ensure the V/Oct tracking.

Modules are now ready / packaged we ll contact the retailers this week !

Too new to this to have a "usual"; Elevator Sound, London Modular and matttech have all been lovely so far.

Latest Mylar Melodies' podcast with Divkid reminded me about the HiPass; wonderful little module; packs a lot in 2hp ! Cleaning up the master stereo mix (can be put in the aux send loop of the Performance Mixer, perfect !) + 2 hi pass to clean samples or individual sounds or feedback paths, so my filters are free !

Ordered ;)

I've had the SumDif racked up for about a week now and it's great! I'm using it mainly for M/S processing but it's finding its way into other patches as a basic utility.

And interesting behavior as a logic gate, I don't think the A-B out fits any of the typical logic types. It only puts out a positive gate if A is high and B is low.

Was surprised how using a phase inversion on one component of mix can change the mix sound. For example the plus and minus outputs give quite different results while summing two kicks coming from a peaks.

Am I correct in assuming that mid side processing would remove any panning between the left and right, so the final signal would have identical left and right channels?

My understanding is that if the side is processed as 1 channel, when it is returned and split to the left and right again, it would be the same on both sides?
