Clock Divider and reset

Post by evs » Mon Feb 15, 2021 5:41 pm

Hi,
i have two clock dividers that are considered doing musical and not mathematical divisions.
That is the G8 and the Time Wizard.
But there's something i don't understand in their behavior.
I reset both on start. But they divide mathematical...
meaning if they divide by 2, than 2 and 4 is high. NOT 1 and 3...
(as i understand 1 and 3 would be considered musical..)

my set up here: a machinedrum gives out midi clock to a doepfer a-190-8.
There i patch a clock out to one of my clock divider and i patch the start to the reset in...
all the outputs go high on the second clock... and not on the first one...

what am i missing?

Edit: changed the title as it is misleading..

not really, they just say what a musical and what a mathematical divider is.. i saw it earlier and he is just saying what i´am saying. at least i believe so.
but question is, why do my musical dividers behave mathematical?

Maybe they really are mathematical, not musical?

It seems that they divide musical, but that the first trigger in does not count..
For instance if I divide by four, they all go up on the beginning at the Second Input.. neither a mathematical or a musical divider would do this.
So it seems that they ignore the first clock coming in.
Both the time wizard and the g8 are doing it.
So I guess there Must be something with the a-190-8...

Could this help ?

" I just got a G8. The different modes are great - the first mode is the same as the A-160, but "musical". Not remembering the last mode used is a PITA, just like the uscale. As I have 2 uscales and a G8, switching on the modular is a bit like booting up a computer - I have to set up 3 modules before it sounds right. Hopefully a new version of both modules will remember the last mode (one day!). "

And did you check the "Wait control input" in the Doepfer module ?

Perhaps your modules` reset inputs react to the falling edge of the reset gate. That could explain the "missing first clock". Un-check jumper JP9B and see if it helps.
I have an A-160-2 and had to do a bit jumper setting myself until it behaved the way I needed it to be.

We had to use this module to fix a similar problem with our clock system :

Perhaps it could be possible to find one on the used modules market.

I‘ve tried that, the g8 and the Time wizard seem to react on the rising edge..
I have set the start to trigger and not to gate on the Doepfer.

I tried a bit further and used a maths and a brain+pp as The clock and reset givers. Same thing there. A bit weirder even. I made a video to show this.. I will try to link it in a minute..

Please pay attention how the g8 reacts differently each time..




Explanation: maths into clock divider. Also into brains to clock it. Gate out of step 1 of pp into reset of dividers.

oh, and about the videos, have a look when the sequencer is on the one, and when there is a reset happening at the divider on the left..

Is this maybe what you need?

Ah, maybe! Guess I will try first patching something like that with maths (should be possible, or?) and if it works I’l buy that..!

The issues which are (hopefully) solved by the Ladik U-090 are discussed in depth in this thread: viewtopic.php?f=16&t=166898&hilit=du+seq&start=150
You might find some similarities to your problem there.

I tested a bit, and the Interesting thing is that when I delay the reset trigger nothing changes, but when I delay the main clock a bit (with a maths) than everything runs as expected!

Glad this worked out. I have to find a solution for this myself, as my DuSeq behaves exact the same way. Luckily I`m clocking and resetting my whole modular with Expert Sleepers and Reaktor, so I can to patch this up ITB. No need to buy more modules, hehe.

That makes complete sense. The reset has to occur before the clock advance.

It has to be synced with the clock pulse. That is the only way to get reliable resets.

Strange that it’s not at the same time from the Start..
Do you think it’s a Problem from the doepfer module or from the machinedrum?
