Doepfer

Hi. I noticed that Bakis, in a recent post, mentioned syncing an A155 
to the A190 using the reset output.  Since I recently put together a 
small Doepfer system, I could really use some good advice on how this 
is done.  
I have been unable to get any kind of meaningful midi sync: yes the 
tempo is right, but the sequencer won't start on 1. The notes are 
more likely to occur on, say, 1 and 73/960, etc.  So, I have been 
recording midi notes at the desired rate to trigger the A-155 off of 
the gate output of the A-190. 

I would very much appreciate some tips on midi sync.  Thanks.

I notice from the 'Database' section that this same problem is 
mentioned there, so I'm wondering whether it's one of those things 
one has to live with. I've just got hold of a 155 myself, and will be 
looking at it over the next few days. I don't know whether I shall be 
able to help out on the MIDI front (unless I can work out how to get 
my PC to output some sort of MIDI clock, but I'm no musician), but if 
I come up with anything I'll let you know.

Again, I'm wondering if lack of response from other group members who 
would have more idea than me, reinforces the above (?)

Actually, I have no problem with the A190-A155 combination.  I mean, 
there is a slight lag (which I assume is down to the MIDI digital to 
analog CV conversion), but the sequencer parks at step one, and 
starts at step two.

The lag doesn't bother me much, and seeing as how I multitrack 
things, I can offset the lag.

What is supplying the MIDI clock, and how is the clock being routed?  
I'm certain you know this, but try never to supply timing critical 
MIDI data via a THRU port.

The A155 as mentioned always resets to step 1 and starts at step 2.

Not sure what's causing the lag, but if you're using a software 
sequencer its possible that a lot of active sensing messages or other 
spurious midi messages are clogging the A190 processor a bit.

same here, resets at 1, starts at 2.  i've never had a problem syncing midi 
clock from any source to the a100.  i do this regularly using either software 
(logic, reaktor, or max) or an mpc.   

patching my a190 clock directly to the a155 usually results in the a155 
running at light speed which is too fast for my taste. 

i nearly always patch midi clock from the a190 into an a160 clock divider first, 
then to a155.  more useful divisions of tempos that way.  also, if you have an 
older a155 which steps randomly and sways a bit (nice!) when fed a 
sawtooth, the 160 will straighten this out too so the stepping is no longer 
random.

fun to send clock from the a190 to the a113 as well.  this provides 'even' as 
well as 'uneven' divisions of clock which can be mixed and fed to your a155's 
clock input.  can be downright funky, though often hit or miss (literally).  one 
cool possibility of doing this is switching 'mixturs' on the a113 for rhythmic 
shifts while flipping the switches around on the a156 cv quantizer to change 
note groups.

speaking of funky clock, i'm curious about blacet's new 'binary zone' clock 
tool.  looks interesting though i can't really figure out what it does just by 
looking at it.

Hi Joe 

> The A-155 as mentioned always resets to step 1 and starts at step 2.
I don't own the A-155, but I think this is normal for counter like also the
A-161. A clock-transient at the counters clock-input causes the counter to
advance for one step. If the counter was resetted before, it stands now at
step 1 and the first advance will go to step 2.

I think the sequencer should start fine at the step 1, if you send the
start stop signal also to the reset input. If reset does not go for the
transient, but for the level, then send the Start/Stop-signal through a
A-162 set to minimum.

This is precisely it - don't know why I didn't see it sooner. Thanks 
for the replies: as I mused in my reply to the original poster, 
basically it's something you have to live with. I still have a lot of 
experimentation to do, especially seeing if I can get a MIDI clock 
out of the PC.

Incidentally I have drafted out a circuit which will allow voltage-
controlled division of a clock signal (as the 163 if you put the zap 
on the coupling capacitor), but which is 'resettable' at the start of 
the cycle (which seemingly the 163 won't allow). This should allow 
the bottom row of the 155 to be used to define the current note 
length as an exact no. of multiples of the clock cycle (say from 1 up 
to 16) - thus taking the hit-and-miss approach out of using a VC LFO. 
Presumably when using MIDI clock signals one can set the clock cycles 
to be some multiple of the desired note lengths, so if 16 cycles was 
a 'standard' note length, then divide by 1 to 16 gives sixteenth 
notes up to 'standard' notes (?). Anyhow, I hope to order the bits in 
a day or two so that I can give it go.

Tim

all analogue sequencers synced to midi clock start
from step two!(because they reset to step one and not
to step 8.)

nope...the a155 starts from step 2 even when i send it
the a190 reset signal to the a155 reset input.

To the best of my recollection, the Analogue Solutions sequencers reset to
the last step, so that they will start on step 1.

Hi PS

I remember making a similar comment early on in the group, and bakis 
had to embarrass me by telling me to read the A190 User Guide to find 
out how to set it's internal clock divisor.

thanks joe, was not aware of an internal clock divisor in the 190, will read up 
on it.  

will still keep my 160 right next to 155 for now.. : )

> will still keep my 160 right next to 155 for now.. : )

Good plan. It's convenient to use the A160 with the A150 VC Switch for 
16-step A155 sequences. You can also tap off two or more of the 
divided A160 outputs to vary the sequence with some logic processing. 
(I don't have the A166 logic module unfortunately, but it isn't 
difficult to accomplish the same things with an A138a, A132, and 
A165).

Joe

hi brandon,
nope,i think they reset to step 8!(that is valid for
the GT8,SQ8 modules).they only reset to step 1 if they
are internally connected to the MC01 master clock
module that is now discontinuied...
well,i'm not sure about the oberkorn,but this is an
analogue/midi sequencer,so it doesn't really count ;-)

i like doing this too.  been thinking more about the 166 myself.. 

hard to get my head around it w/o trying it, but was thinking about attempting  
to add gated clocks, via a177 double foot switch gates or keyboard.
