A160-5 latency

2016-10-17 by jaccoville@yahoo.com

Hello Doepfer users,

When setting up a patch with my A160-5 clockdivider I noticed that when I send a CV to the multiplier input for creating ratcheting there is a latency of one sequencer step.

To be clear: I made the patch classic.

See example in the manual.

So one A155.

The point is that I have to set the CV step on sequencer step, let's say, 7 to get the ratcheting effect on step 8 in the sequence.

Is this normal?

Best regards

This is stated in the manual. And if you think about it, it makes sense doesn't it?

There are no electronics yet, that have psychic powers ;-)

Well for me this note in the manual is about the clock input which has to be stable and infact it is in this setup.

Only the CV input is getting a voltage which fluctuates to get the ratcheting    effect.

I just used the A-160-5 for a performance in Munic (DigitalAnalog Festival)
and cannot confirm this behaviour. You should use the pre output of the
A-155 to avoid any delay. If this does not help please contact Christian
Assall (software@doepfer.de). He programmed the A-160-5 firmware together
with the A-155.

Hello Dieter,

I made the patch exactly by the book. 
To be sure I made it once again. 

What I notice is that once the CV from the A155 sends a voltage the A160-5 does shows this by increasing the leds BUT the actual ratcheting of the notes to my A140 adsr follows AFTER the CV has passed, so the next note makes the ratcheting sequence. 
For me it seems not logical. 
There is always a steady masterclock to the "clock in" of the A160-5. 

Best regards

Hello Jacco,

just think twice:

The voltage which sets the division/multiplication factor, comes 
slightly after the clock-tick, that should be multiplied. So the 
multiplying/dividing will happen for the next clock tick. Why comes the 
Voltage after the clocktick? Because there is a minimal delay within the 
A-155. There are rise times in the 4051 and in the address dividers, 
which do the sequencing in the A-155. These are in the range of 
nanoseconds. But this is enugh to be "to late".

So yes: I think it is normal that the CV will set the multiplication 
factor for the NEXT step.

Hello Florian, 

Thank you for your clear explaination. 
I like the A160-5 to use but I have to have to attention to place the CV one step ahead which isn't a big deal. 
Now I know why 

Thanks again 

Jacco

Ah yes! Of course, sorry Jacco I did not read your message correctly.

And in the end it is a faulty microprocessor. 
I contacted Doepfer about this and they confirmed. 
Change of processor and go!

Hi there all,

After having mail contact with Chris from Doepfer who offerd excellent service to take care of a new processor I couldn't resist also order a new A160-5 at Thomann.

Once installed in my system it worked like a charm, no latency issues or whatsoever.

Thank you again Chris for your help with this and with sending me the long

awaited update software for my A157's.

Cheers

Doesvthat mean there are lots of faulty microprocessors? I just assumed the one step latency was expected as stabilisation time for the mutiplication routine. Is mine faulty too?

Hello Jonathan,

There should be no latency....
So I recommand to contact Chris about this. 
No worries, very correct and friendly service. 
Just swapping the processor and your good to go. 

Best regards

Jonathan, you are like me before in this thread, mistaking the bit about the steady clock with the problem that Jacco was experiencing.

Hi Jonathan,

If that is the matter what Ernst said.
Your (masterclock) has to be steady, at a sudden tempo change the A160-5 will need a few pulses to adapt.
However, this shouldn't be the point with the multiplier/ratcheting function. When sending different CV to the CV input it has to spit out the multiplied pulses direct and with no delay, so spot on. 
The last thing didn't happen with my A160-5 so that was where the faulty processor showed up. 
Make the basic patch like described in the manual and you'll notice right away. 

Best regards

Jacco Ville
