Oooo...so, it's less like a Doepfer A-160-2 and more like a 4ms RCD _with_ some of the expander functions thrown in. I like it!!!

Do you know a way to hard reset the module??
Are all inputs protected from more than 5v or neg voltage??
I fed a MODULATORS lfo to CLK input and sometime in a patch making it freezed...
I contacted support to see if I can get a schematic for debugging the module.
Any idea on how to defreeze MM welcome. tnx.
PS: There is the possibility, that one of Kastle Drum, and or Kastle input (Feed, pattern, etc) could Have inadvertly mismatche Input with outputs and sent a feedback signal back to the MM divider outputs...

Are all inputs protected from more than 5v or neg voltage?? Only question I can definitely answer and it is most definitely NO! Do not out more than 5V or neg voltages into any AE module except the 4I/O, and also the I/Os on the master/power modules..... |

I do not know the Kastle output specification, 4I/O was not used, as power module... the only module that could have is Kastle... Im scoping Kastle output, they are about 0 to 5v. Kastle BIT IN and Kastle Drum FEED have an output of about 0 -3 volts, stepped Lfo... I thought they were input, not output... Label BIT IN is misleading... I'm pretty sure i tried those connections with the MM DIV outs... MM DIVIDER disassembled. Probing U1. It receives 5v rail, and input clock. Clock shifts outputs when the shift knob is rotated and it is read by probe BUT no led activity and signal on the output. it's like the pull up function * output drive, has gone off... I guess that function is in U2... I have an arduino Uno if this could make any difference for debugging... PS. Accidentally coupling U1 rail pin 15 and pin 14 that should be output 1 and 2?, the Led lights up at the clock rate... output probing also gives a positive clock out reading... idk... PPS: I havent touched (probed) U2 in any way... PPPS: I switched the scope to AC mode.... now the FEED PIN of KASTLE DRUM gives a reading of +4/-4 peak to peak... so most likely, MM DIV has received neg -4 voltage as well... perhaps a 1N4148 to protect the output would be enough to protect outputs...  Possible upgrade??  Attachments:

I got the Spreadsheet of the Bit Shifter 74H595D at hand.
I have a spare 74H595N available also on a BB.
It's out can not sustain more than -0.5 for long without damaging the IC it seems...
Don't know schematic if input clock passes be4 at the Atmega88, and what are the conditions for it...
output should not in my view have damaged the Atmega as those are connected to the BitShifter only (hopefully)
there is no path back to the Atmega from the output perspective...
So, I was bridging Direct Serial DS pin 15 to Q0 output... thats why the led lightn up yesterday...
Master Reset is in HIGH, as it should be, but pressing the Reset button, doesn't send it LOW...
I'm unable to specify Clock register and Storage register situation. I know it's provided by the Atmega88, but
don't know the specs... So can't say it's normal or not... pins 9 LOW, 10 HIGH 5v, pins 11, 12, 13 seems to be all LOW, 14 mirrors LFO clock input, 15 LOW, 16 VCC 5v. Qns 1 to 7 all LOW.
IF the 74H595D is damaged, I can try desolder and implant the big cousin N version, impedance would change a bit
so consumption but it can be done (sigh)
I'm stuck here atm, waitn for help, I hope I havent break warranty by probing the dye...
Bye.

Done a little bit of reading; the Bastl instruments are both 0-5V so should be fine with the AE, which your scoping suggests also.
No modules with in the AE give out negative or more than 5Vs so your modulators module shouldn't be a problem.
The other stuff you need someone much more tech savvy than I am....
I would email Tangible Waves, usually slow to reply but they will get abck to you.

Also having issues with the MM-DIV. Talking with tangible support about that now after having two of them break in the same way.
Might be related to the KÆSTLE for me as well? I do have one in my case, patched it with the MM-DIV etc.
Has anyone else had a MM-DIV just... stop responding? Or is it just us?
---
I'm pretty sure there shouldn't be any negative voltages or >5V anywhere in the system, so long as you use an official power supply / power module, then patch entirely within the AE system.

It's not just you, but also me.  Two days ago I received my Synth Explorer Ultimate, and one of the first things I did with it, was to connected its LFO square wave output to the MM-DIV module CLK input. It ran its 1...8 LED's through once or twice, and then turned them all on. After switching power off and on again, the LED's are all off and it haven't been reacting to CLK signal anymore at all. The Mode selector and its LED's work though. Also something is wrong with my METER module. Sometimes, usually after the synth has off for hours and powered on, METER module displays upper half is blank and the display brightness fades in and out constantly in few second cycles. It does the same in every mode. But after a while when I power it off and on again, the display works normally. And the next day same occurs. I don't have proper statistics about that yet, as I have had the unit this far only for couple days. All the other modules work, although I haven't yet tested the Braedboard, but I don't know what even could be broken in it. Otherwise I'm loving my Synth Explorer Ultimate and I'm already wanting more modules! |

Not sure about the divider but i know the thing with METER has been brought up before, and it was suggested to be something to do with the power-up timing of the screen vs the rest of the module - try turning the power supply on at the wall *before* connecting to the master module. I think that worked for others?

Possible upgrade?? View AttachmentThe kæstle won’t output voltages out of the range of 0-5v, I would suggest that the apparent +/- swing is just an artefact of the ac-coupling on the meter. for both Kæstles the feed and bit inputs are indeed inputs, however there are some resistor biasing things going on, so I hope that explains the apparent output. There is also some weird stuff happening in the bastl firmware (which I copied directly of course as it’s a clone) where inputs are written to before reading. It might be worth me reviewing the code to see if an update is possible. |

The scope's ac mode is IMO a bit misleading in a sense that it does not display negative values (AE modular does not do negative voltages) but instead shows voltage in the 0-5v range around a 2.5v center AFAIK.

You should talk to tangible support -- mine are on their way back to Germany for free repair.

Hello all, I've just received today my MM DIV module with a full 20U row  everything works great but I have the exact same problem that you describe :
Feeding a Square LFO from 2LFO or Modulator ( can't remember, but could be modulator) , all 8 leds started blinking very fast, then just shut off.. Now there is now way to make it work, i've tryed any clock source available, also audio from oscillators, and also a attenuated 5V output from the Master I/O , that was able to trig any other module except MM DIV.. Looks like the input stage could be dead ? after less than 1 mn of use  Will contact Robert and team by mail, but if anyone succeed to unblock it.. As pazigamer the mode selector and it's Led works good, but no way to clock the module... Thanks for any hints. Bye It's not just you, but also me. Two days ago I received my Synth Explorer Ultimate, and one of the first things I did with it, was to connected its LFO square wave output to the MM-DIV module CLK input. It ran its 1...8 LED's through once or twice, and then turned them all on. After switching power off and on again, the LED's are all off and it haven't been reacting to CLK signal anymore at all.

Hello just a second message because I received my MMDIV replacment module ( thank you Tangible team) .... But t fryed again ... One minute of dividing, then all LED blocked, then no more outputs, and LED's configuration different at each startup ( can be all 8 LED fixed or LED 1-3 then 7-8 , whatever.... ) Can't get clock division working in my system I've just patched it with the output of a square wave LFO in the CLock input, and trigger outputs to some enveloppes modules.... ) If you have any hint.
thanks

yes this is horrible to hear as it's such a cool module. not had any probs but always gone through a Beat divider first. won't ever be going direct from LFO just in case.

I only got my MM-DIV to freeze on rare occassions when putting audio-rate pulse wave to the input (using it as a subharmonics oscillator) at high pitches. But it was always able to recover by unpatching and coming at it again with lower frequencies. So maybe there is a maximum frequency that it supports...

I have another question about usage for polyrhythms, in my case a 4 vs 5:
My patch takes a high frequency clock into a MM-DIV in "DECIMAL" mode. Then I use the 4 and 5 outputs as clock inputs for two step sequencers, respectively.
in my case the 5 divider clocks a TRIG164, yielding 16th notes, while the 4 divider clocks a Euclid Grid, running a 20-step pattern of quintuplets. So far so good, and this kind of works as expected.
A complication arises when dealing with RESET: I use a single trigger signal to reset all these 3 modules simultaneously, to bring them in sync. But, doing a reset this way means that the two sequencers don't receive their first clock step at the same time, meaning that there is a phase offset in their patterns. This is because the MM-DIV in DECIMAL mode does not trigger all outputs on the first clock trigger after reset.
Is there some trick I should know about resetting "follower" sequencers that are both clocked by the same clock divider? Or a way to make reset in MM-DIV start not from start (count 0) but just before 4*5=20, ie, count 19?

To illustrate my point, I want to visualize the output of MM-DIV in different modes, to highlight how the behavior is different beyond the choice of clock dividers:
To start, in "BEAT" mode, we have clock dividers with factors 2, 4, 8 on the first outputs, all triggered on the first clock after reset:
Step | 1 2 3 4 5 6 7 8 9
Clock input | x x x x x x x x x
Output 1 | x x x x x x x x x )
Output 2 | x . x . x . x . x
Output 3 | x . . . x . . . x
Output 4 | x . . . . . . . x
This is easy to use musically, eg to trigger percussion.
Compare this to "DECIMAL" mode, where the first clock only triggers the first output, while the other dividers "start counting from 0":
Step | 1 2 3 4 5 6 7 8 9
Clock input | x x x x x x x x x
Output 1 | x x x x x x x x x
Output 2 | . x . x . x . x .
Output 3 | . . x . . x . . x
Output 4 | . . . x . . . x .
Here, we would need 12 clock signals to trigger the 4 first outputs simultaneously.
Similarly, the "BINARY" output, where the outputs produce a binary representation of the count, meaning that we have clock dividers in powers of 2, albeit phase shifted:
Step | 1 2 3 4 5 6 7 8 9
Clock input | x x x x x x x x x
Output 1 | x . x . x . x . x
Output 2 | . x x . . x x . .
Output 3 | . . . x x x x . .
Output 4 | . . . . . . . x x
To rephrase my question above: Is there some way to make MM-DIV behave like in "BEAT" mode (all outputs in phase, starting after reset), but using the dividers of "DECIMAL" or similar?
