Is it possible to modify the A-160 clock divider so that it starts with firing all the gates and goes from there? That it counts from the top instead of from the bottom. Now I have to wait say 32 clocks for it to fire the /32 gate for the first time. It would be easier to run multiple clocked devices in sync if they all started on the downbeat. Martin

you can achieve this behavior by combining multiple doepfer modules. invert the clock output that you want to use, then using VCAs and mults of signals like run/stop and a start pulse you can get the behavior you are looking for. others may be able to chime in with specific patches. I haven't had run/stop or a start pulse available yet to mess around with this stuff. DIN-sync has some of these signals which I may tap into to get more functionality in this area, if I cannot hold out for the STG stuff to come out slowly but surely. I think the 4ms RCD does this out of the box as well.

Maybe adding inverters do the job you are asking for . In this case all (inverted) outputs will turn high on each reset. Best wishes Dieter Doepfer

Hello That is something which annoys me too. I think the A160 should be dropped and a A160-2 should be introduced instead which uses a CD4029, which can be switched between counting up/down and also with a presettable reset position. Florian yahoo@doepfer.de schrieb:

Will this also be able to do the uneven divisions I have been bothering the list with earlier, Dieter?? If yes then this will be a very very nice new addition to the Doepfer range!! grtz Ernst On Tue, Nov 23, 2010 at 10:12 AM, <yahoo@doepfer.de> wrote: > > > > Hello > > > > That is something which annoys me too. > > > > I think the A160 should be dropped and a A160-2 should be introduced > > instead which uses a CD4029, which can be switched between counting > > up/down and also with a presettable reset position. > > > > Florian > > We are about to design a A-16?-? that will use a microcontroller instead of > a hard wired counter.

i´m wishing for cv in so that it can be used as a A/D converter i´m currently using a modified A-152 T&H module as a 3bit A/D (fun to use as color select on my spectra physics 168 argon/krypton ion-laser :) /martin

We are about to design a A-16?-? that will use a microcontroller instead of
a hard wired counter. That way different counting and reset types could be
programmed and selected by the user (e.g. counting up or down or up inverted
or down inverted or ... , immediate reset or reset at next clock pulse,
advance to next step at the falling or rising edge of the clock signal).

> Will this also be able to do the uneven divisions I have been > bothering the list with earlier, Dieter?? As the module is still in the design state I cannot give details. But as it's microcontroller based it should be no problem to include different counting/dividing types. The main problem is the operation (i.e. how to set the dividing type and how to tell the user which type is chosen). An LCD with menu buttons would be a bit over the top and increase the price unnecessarily. Jumpers inside only and looking to a table would be a bit laborious. So we will have to find a compromise between price and operability. Best wishes Dieter Doepfer

something like this http://www.alpha-products.com/cd_catalog/new_catalogs/switches/std/dip/rotary/dip%20rotary%20sw2.htm for selection would be great you both get many positions and feedback to the user. and it´s easy to interface to a mcu another way is to use a pot connected to an analog input on the mcu and give binary feedback with led:s or hexadecimal feedback with a 7 segment display my personal favorite is the one with the pot and four led:s for binary feedback (then it´s easy to modify it for function selection via cv ;) skip the lcd thing it´s only expensive /martin

is it possible to incorporate "gray code"? http://en.wikipedia.org/wiki/Gray_code /martin
