Hi all,
I have a Question in general. When booting up, my Syntakt shows me os “c 1.20”
At the Electron support page, the latest os is “a 1.20”
Do I have the latest os already?
Whats the difference of the letters “a” and “c”?
Thank you.
Latest Syntakt firmware is 1.20A
The letter comes after the version number, and normally indicates some bug fixes without major change.
Do you see 1.20C or a C in the lower left corner, and 1.20 in the lower right corner?
Then you can upgrade to 1.20A 
Not sure what the lower left letter means exactly, but it doesn’t give an information such as the OS version.

Hello LD,
thank you for the quick and helpful response.
Ok understood. Means i can upgrade to 1.20A
This is what I have:
In the right corner, it says “1.20” no letter here.
In the left corner, it says the letter “c”
Still wondering what the letter “c” in the left corner means out of curiosity…

Yes indeed.
Here is what you’ll get.
Bug fixes
When copying a sound from an analog track to a digital track, FILTER WIDTH was incorrectly set to zero.
The wrong parameters were randomized when randomizing the SYN parameter page on the SY RAW machine.
In some cases, trigs could be added to the sequencer when toggling mutes in permanent mute mode.
The device could crash when a song row was added to a song that was cleared while it was playing.
A sound with the BD Silky machine sounded distorted if a sound with a rimshot machine had previously played on the same track.
When a trig with a sound lock with a different machine than the track sound was held, it could in some cases result in a graphical glitch.
The FX track was incorrectly called “MID.13” instead of “FX” in the SCALE menu.
It was impossible to toggle the FX track song row mute outside of song edit.
It was not possible to open the sequencer RETRIG menu on the FX track.
That’s everyone here I think ^^
@Patrik? @eangman? Or anyone that has the knowledge?
Would you care to explain us?

It’s only used and meaningful internally at 
HQ - no use to the end user and not important for OS decisions
This was explained to me years ago - I have replied often to such questions with an equally vague explanation, there was a similar query answered officially recently but i can’t locate it to link the exact wording
essentially - just ignore it (unless it’s asked for)
