Grandmother - calibration, patches and the don‘ts

Postby BLFTJ » Fri Mar 22, 2019 12:31 pm

Hi everybody,

I‘m new here so forgive me if the followin may seem stupid. I already own a subphatty, big fan, few other synths, toys... everything fine... I‘m about to buy a grandmother but i dont know much about the modular world. Plus i read a lot and found a few things that made me think...

First question:
I heard about issues with calibration of the mod wheel, tuning oscillators etc. A „need to calibrate“ grandmother. How would i find out if i need to calibrate something, will i hear it?

Second question:
For a modular-beginner... can i harm the circuits by patching somethin wrong? I mean is there any mistake that i should definitly avoid while doing patches?
Thanks in advance!
Greetings from germany!

Hello,
1- Yes it's better to calibrate. It's very easy to do. Have a look here : https://www.sweetwater.com/sweetcare/articles/moog-grandmother-calibrate-and-update/
2- There's no risk to damage the GM with a wrong patch, don't be afraid.

Example of calibration need, when I got mine, with the mod wheel all the way down, if the pitch or filter knobs were turned up, it would modulate the signal anyway- It takes 5 minutes, so you should just go ahead and do it regardless, in case it's just a wee bit off...

When I got mine brand new, osc 2 was in tune with osc 1 with the tuning knob turned a quarter turn to the left, and I had a weird keyboard issue where the notes would be fine and then get to a certain point and it was all a semi-tone out.

The calibration fixed it, but I had to install the latest firmware and go through everything a couple of times, it wasn't a process for the feint of heart.

It has been rock solid ever since, 4 or 5 months now.

Your biggest danger with patching the GM is that you will be pulled into Eurorack before you even realise it. That's what happened to me, all of a sudden I have MI Plaits running into the GM, and it is... incredible...

Sounds like i really should go with calibrating directly after buying but i‘m gonna try to find out if there is something wrong by listening close...

Damn i heard that a lot.. that warning about getting pulled into eurorack stuff. :roll:

But i will take that risk.
