Hey Ryk, Issue wasn't during the soldering process.
What happened to me was that I'd soldered everything in, and was turning the PCB over to go onto install the LED's and one of the slider switches was all wonky, as I say it was already soldered in place, and flush with the PCB.
The thing is, the tops of the slide switches are only held onto the base with a few tiny folds of metal.
I have a soldering mat on my desk to protect it, it's a bit grippy, so a bit of sideways motion was enough to easily unseat the top from the base.
I put it back straight and it works fine, just a heart jumping out of mouth moment.
Phew !

Glad I everything is ok.

Hi Ryk,

Are you planning to offer the euro kit for the foreseeable future, or is this a "limited edition" affair? It's an exciting project, but I'm not sure whether to pull the trigger when kits are available tomorrow, or whenever the next batch is released.

Thanks!
Lukas

Hello

Hopefully I will be able to offer the kits for a while, don’t worry it’s not going to be a limited run.

Only if and when I can go back to work there might be some delays in the kits being available, ( M185 is not my day job )

Its alive and kickin! Building it was fairly easy and the build manual is excellent.

I'm not quite sure i fully understand all of the functions and combination of modes, will have to experiment some more . Thanks RYK! :sb:

Was super excited when the postman dropped of my kit this morning, only to find one of the PCBs was missing! Oh well, have emailed and hopefully will be able to get one sent soon. In the mean time I'll just be eying the components and build guide forlornly – the panel is beautiful!

Is there any documentation available for this version of the M-185? I already have an Intellijel Metropolis, which I love to bits, and I would like to see what the differences are between them.

Hey Jose, good to see you here! Its a nice combo, the M-185 clock output works nicely with the polarons trigger input. Let me know how the Polaron build goes for you!

Ok, here we go:
- Are any of the Menu Settings persisted when the module is powered off/on?
- I'm a bit confused about the Fixed Sequence Length function: Does it work when in AB mode? I guess not, since in AB mode the stages control button defines the last step of B and not the overall length of the sequence. But if so, does the fixed sequence length setting make any difference to 'forward' when AB mode is used? I'd love to be able to use it, eg. play A 3 times, B 3 times but still reset to stage 0 after e.g 32 clock pulses
- In the manual it says about the A+B CV offset function: "is is useful when creating a looped pattern in Sequence A,
and using a slower pattern in Sequence B to change the key of Sequence A.": Is it possible to use different clock divisions for A and B ? Or how would i have a slower pattern B?
- I have some other behavior i cant quite explain: Power module on. All stages set to 1, all Gates to multiple Gates, Mode set to Fixed Sequence Length, and Split Mode to A. Stage Control is at 4. Now when i start, the sequence plays until step 6 then jumps to the first step and rests there until it starts again after 16 clocks. Why does it only play until step 6 and not until step 8 before it jumps back to 1?

Thanks!

Very sorry about that.
A few packages seem to have gone out without the smaller PCB.

The packaging dept [me] has been repremanded ! :doh:

Ok, here we go:
Hello

Here are some answers to your questions:

- Are any of the Menu Settings persisted when the module is powered off/on?

Yes all menu settings, AB settings, glide settings etc, are saved to eeprom. [ even the CH2 alt CVs ]


- I'm a bit confused about the Fixed Sequence Length function: Does it work when in AB mode? I guess not, since in AB mode the stages control button defines the last step of B and not the overall length of the sequence.

Yes & No.
Depends which split AB mode you are using.
If serial AB mode then no the fixed-length does not work, as the loop points are defined by the split point, and the MAX stages.
If in parralel AB mode, then sequence A can be fixed length.


But if so, does the fixed sequence length setting make any difference to 'forward' when AB mode is used? I'd love to be able to use it, eg. play A 3 times, B 3 times but still reset to stage 0 after e.g 32 clock pulses

It could do. New software implementation is certainly possible.
You mean 32 clock pulses for the total sequence [ A-loops + B-loops ] or 32 clock pulses for each loop ?


- In the manual it says about the A+B CV offset function: "is is useful when creating a looped pattern in Sequence A,
and using a slower pattern in Sequence B to change the key of Sequence A.": Is it possible to use different clock divisions for A and B ? Or how would i have a slower pattern B?


Yes. Although it's implementation is actually stage length multiplication. So the stages can last 2,3,4,5,6,7,8 times longer than the stage length setting.
The multiplication is set by the B loops value [ on switch setting ### for the AB split points ] Sorry it is not very intuitive.


- I have some other behavior i cant quite explain: Power module on. All stages set to 1, all Gates to multiple Gates, Mode set to Fixed Sequence Length, and Split Mode to A. Stage Control is at 4. Now when i start, the sequence plays until step 6 then jumps to the first step and rests there until it starts again after 16 clocks. Why does it only play until step 6 and not until step 8 before it jumps back to 1?

Oh dear !
That would be a bug ! :doh:
We rather rushed out a new version of the software with quite a few new tweaks, but forgot to check the Fixed Length mode.
Sorry I'll look into that, and send out a firmware update.

Thanks

Hello

The big difference to the Metro [ in core functions ] is the M185 has 8 gate modes, instead of 4.

This allows for beat subdiv per stage for the repeat note gate mode.
So one stage could play 16ths, another stage could play 1/4notes etc.
There is also a programmable beat pattern gate mode, useful if you don’t want the note to play on the first beat of a stage.

The other major difference is the M185 sequence can be split into two [ A/B split mode]
This can be either serial split [ 5 repeats A seq, 3 repeats B seq etc ]
Or it can be parallel split [ two separate simultanious sequences ]

There is also a 2nd channel of CV & Gate, which is used for the parallel split mode, and also as an alt CV for normal mode.
Finally the M185 has MIDI ! So you can sequence your DX7, Juno106 etc or sync easily to modern drum machines or DAW.

[ plus there is a two player video game, but no-ones seems interested in that ]

The user manual is available to download from the webshop
https://rykmodular.bigcartel.com/

Sorry I haven’t posted many videos yet, I will try and get round to that.

Built mine today, fairly straight forward, my kit gained a resistor but was missing an led! luckily the bi-colour leds from mutable builds are the same. One question, how accurate is the calibration procedure and the cv output? With the calibration procedure I managed to get within a couple decimal points of the required values across the full range. Is this normal or should it be more accurate?

They are on dropbox but I don't need to sign in to download them. There's a download button next to the sign in button that works. Swapping out

Code: Select all

?dl=1
in the URL (e.g. https://www.dropbox.com/s/o0rfr1f72z5u6 ... 4.pdf?dl=1) also works.

Hello

Sorry about the LED !
It seems not a good week for me.
I can send a replacement to replace your replacement.

For the calibration it should be possible to get acurate to 2 decimal places, which should be good enough for most analogue VCOs.

No problem Ryk just double checking, I have plenty of leds! Great work, I was testing it last night and is really fun, the split and cv add functions really give this plenty more flavour to my metropolis :)

The packaging dept [me] has been repremanded ! :doh:
Already got the replacement, cheers for that!

I've got everything built and it (i thought) calibrated correctly – however I've got an issue where if I have the Gate Mode set to Off on voice 5 the sequence stops, the LED turns green and stays stuck on step one. I feel like this is probably caused by a short somewhere but after scouring all morning I can't see any dodgy soldering. I don't suppose you'd have a suggestion on where to look? From what i can tell the switch itself is soldered well and no jumps

thanks for such an awesome module!

Hello

When it locks up with green LED at stage 1, can you move the LED with the NEXT and PREV buttons ?

If so, it sounds like there might be a short between SW-B3 [ Gate mode for stage 5 ] and the Split_Mode select switch line [ highlighted ]. This would cause the Seq to jump into SPLIT programming mode [ ### ].
Please check carefully around the area circled in the picture. [ Which is the underside of board, bottom row of 8way switches, 5th in from RHS when viewd underneath ]

Hello

Yes R15 left leg goes into D1 right leg
Thanks for pointing that out. I have now corrected the BOM document.

PS The next batch of kits has an updated PCB whith this fixed.

Based on PCB photo just shared, and since you're doing a PCB re-spin.
Ryk, might want to move the RefDes from under the installed components? Not going to be much use in a future inspection-repair if they can't be seen.
