G8 Clock divider -- New from Circuit Abbey

[BrotherTheo]

Announcing the G8 clock divider. 8 divider modes, 8 outputs. Shipping this week.



Divider modes:
Clock: 1 of 8 sequencer output, like the A-161
Cv: Same as above but with a CV input on the clock jack
Int: Divide by 2-9
Bin: Binary counter, 0-255
Even: Divide by 2,4,6,8,10,12,14,16
Odd: Divide by 3,5,7,9,11,13,15,17
Prime: Divide by 2,3,5,7,11,13,17,19
Random: Output have a probability of 1/2 through 1/9

Also an expansion connector that brings out the outputs.

See the web page here and the manual here

very cool looking

[oootini]

nice.

So just to understand the Binary mode, the first output is a clock once every 2 cycles, the second is once every 4 cycles and so on up to once every 256 cycles?

I like the visual indication of triggers or gates mode.

Is this unit a "mathematical" or a "musical" clock divider? What I mean by that is, does it put out a clock on the divided outs on the downbeats (musical) or on the divisions (mathematical). For example does the /2 out go high on clock one and clock 3 or high on clock 2 and clock 4? Another way to determine this is on a "musical" divider, all outputs go high on a reset (back to the downbeat). The Doepfer divider is a mathematical one and the 4ms one is a musical one for instance.

This is a big difference and not an obvious one.

Yes.

Yup this questions comes up about every clock divider module, and it's confusing every time, but it's very important. I think the "musical" versus "mathematical" terms came from the thread discussing the Erthenvar Div modules, which ultimately went with a jumper to allow the user to choose which mode to use. I like those names, so hopefully they'll become somewhat universal and everyone will know what they mean.

[BrotherTheo]

Confusing? oh yeah. How can you tell which one is clock one? Are you saying that in binary mode all 8 output are to go high in "musical mode"?

These are almost out of the door - so be clear - what do you all want? I would think /2 would go high on 2 and 4?

[exeterdown]

I like how shallow this is.

[wbuttler]

I think I understand mode 1 "Clock": Outputs 1 to 8 cycle through On/Off, with only one at a time ever on.

How does mode 2 "CV" work? Does this mean the CV input controls which of the outputs is "On"? When is a trigger delivered - when the CV changes?

Also, where can we find the breakout expander?

[wbuttler]

Double post.

I would assume so, sort of like the Doepfer A-152 or SSL's excellent V-Gates, of which the non-divider modes of G8 seems to have been inspired by.

I am into it.

Yes that's exactly it

Yes that's exactly it

So like, upon reset all outputs should be high?

[flashheart]

Nice. The one thing I'd have liked is a set of typical musical divisions, ie. 2,3,4,6,8,12,16,24.
I like the 'sequencer' mode, but I too don't understand what controls the CV switching to the different outputs as it's using the clock in. Is it based on the CV changing, or is it CV addressable?

Well that's actually a different issue. Reset could work that way, which means it's effectively the first clock signal. Or reset could turn everything off, and then the first clock after the reset turns everything on.

The 4ms what one? The RCD?

[albiedamned]

Pretty sure he means the RCD. 4ms calls it count up vs count down on the RCD.

Well done Brother Theo, this looks good

I watched the video, I think I understand now. Changing the CV selects one of the 8 outputs. As a new one is selected it sends out a trigger or pulse. Could be interesting if you send in a LFO or EG.

One weakness of this unit is that you can't have (say) odd and even divisors at the same time. However, this is probably addressed by the expander. I seem to remember a picture of this being briefly posted somewhere?

Edit: No, I was thinking of AcidLab's new clock divider with what seems like a million outputs, including fractional dividers. Seems to be the time for new clock utilities - I don't think anyone has it 100% right yet. If the G8 expander has enough outputs then all Bro Theo has to do is add a shuffle feature and it could be The One.

PS the video taught me that the name is "Gate", not "Gee-ate" - reminds me of an old electronics magazine computer project called the "EDUC8".

[Umcorps]

How wide is the trigger when in trigger mode?
