Ryk M185 Sequencer - per step repeat and gate mode

[forestcaver]

What sort of precision can one expect after calibration? Reading the manual, there is only one trimmer per channel, so how does offset and scaling work?
Looks like you only set the scaling over 5v but there’s no offset control....

Hello

The CV can be set to about +- 10mv with the original firmware.
But there is an offset across the whole voltage range, which you should include when calibrating the CV.

With the new V3.33 firmware beta we have managed to get it down to -+5mv with a much smaller overall offset.

There is no offset trimmer, mainly for simplicity for DIY builds. To calibrate with an offset trimmer requires a
lot of ‘dancing’ between the two adjustments.

It is a compromise, but as all good VCOs should have a fine
tune adjustment, the small offset can be easily be dialled out.

Hello

...

Regarding your Red Button problem, can I check that you have been holding it for 3 seconds
to enable the menu settings ?
You can also try pressing the Next and Prev blue buttons
and holding down for 3 seconds. This should allow you to enter the Menu Settings.

ryk

I tried it and forgot to write. They don't work, neither alone nor pressing both of them at once for 3 seconds.

I can't enter the menu settings at all.

Are you saying the blue buttons do not work at all ? [ for next and prev functions ]
I though you had said the were working . . .

If the blue buttons are working, you might want to try pushing both together but for longer than 3 seconds . . .

Whatever it was -- I made it work. It was an embarrassing mistake on my side. I inadvertently switched it to • mode and didn't realize.

I'm sorry to keep you from doing real support, instead having to deal with my moronic questions. Thanks a lot for your support!

Thanks a lot for the reply - I appreciate it!

Ps It’s an awesome sequencer!

Do you really want 16 step ?
The current version has upto 64 steps, if you dont mind only 8 individual notes

Otherwise there is another way, but you will need 2 x M185.

cheers

I am interested in this "other way". It might be worth building a second one.

Still waiting for the answer to the "other way"

Hi

Sorry forgot about that.

The other way means you need to give up using the MIDI sockets / Reset Input . . .
. . . and then wait for a new firmware !

Hey.

No problem.
Glad you got it all working.

Has anyone heard of any progress on a Reset input?.

Hello

Yes it is available in the latest firmware V3.33 !

Send us a PM or message the shop and we can send you
the firmware.

Hello!

I have recently ordered a kit, and had it built by a friend who is an electrician. After hardwaretesting I observe some weird behaviour:

- first of all, the potentiometers dont work in full range. Checked them in hardware test mode, and they all seem to only work in a range from 2nd to 5th LED (with exception of pots 1 and 2 which work in range 1-4 and 1-5th LED respectively)

- the stage count sliders and the gate mode sliders work in a full range, BUT with each "click" they make the LED jumps back to the beginning before going to the desired position (for example, when I switch from position 2 to 3, the led jumps back to one before going to 3 etc.)

- and apart from that the unit is operating in strange manner - one moment everything seems to work as expected (apart from the potentiometers covering only partial range), but after switching for example from 5V to 5VQ mode the playback starts to act chaotically , activating the stages in random order. Also, the light flickers green on some steps. Sometimes two lights appear instead of one (one green, one red). Other times, the lights completely shut off, and the sequence turns into some sort of drone with gates firing super fast and crazy pitch changes. I tested CH1 in A mode, and similar behaviour goes on when trying to control midi gear.

what could be the cause of this? My friend who built the unit for me checked the soldering and says that it looks ok (and I believe him, he builds electronics all the time in his day job). He told me he suspects a tiny short-circuits somewhere on the board, but he found it hard to check because the connections are covered with black solder-mask, so he couldn't trace how everything is connected. I don't know much about electronics so probably I am not explaining it very clearly.

RYK, could you help find the cause of all this? The sequencer looks amazing after the build and I would love to start using it

Hello

Thanks for purchasing the kit.
Sorry to hear you are having problems with it,

The LED jumps to “1” in hardware test mode for the switches are normal. The switches are ‘break-before-make’ type, and this shows up as LED “1” whilst moving the switch.
So long as the LED reading is stable whilst not moving the switch, it should be fine.

Regarding the seq behaviour issues you mention, they are quite numerous to be able to start to problem solve.
You will need to give more specific details of all the control settings, and the outcomes of each action.

To check for the problem with the Pots, you will need
a multimeter and a knowledge of using one with circuits.
If you are not confident with this, I would suggest you send the module back to us.

For a small fee we offer a ‘bring back to life’ service‘ where we can fault find and repair any issues with your build.
You can send me a PM or message via the web shop fo this.

Thanks Ryk, that's great news!
I will PM you at once

Built this a while back and always clocked it externally, tried to use this as the master click and the tempo is way slow, even when fully CW. CCW it’s practically stopped. What’d I do wrong?

Hello

Have you checked the MIDI Clock Div setting, this also affects the internal clock.
When set quite high you can slow the clock down a lot . . .

What firmware do you have installed ?

ryk

[MindStasis]

Oh wow, I must have set that and forgotten about it. Works great now thanks for the hint. RTFM.

[versipellis]

Does the sequencer need to be stopped to do mode switching from normal serial to, say, AB serial?

[Faustgeist]

Hello Ryk,

What a great product! Any time-frame for the 5U/MU version? I certainly one 1-2 of them

All my best,
~Robin

Thanks

It’s on the list ! At the moment currently getting the Roland version finished.

From my inital sketches for the panel 4MU seems like an ideal width, but any advance feedback would be useful, also kit or assembled ?

No, you can switch between the modes when playing.

Hello

I have finally put up the new V3.33 firmware on the webshop.

https://rykmodular.bigcartel.com/

It is available via the documents download page.

Please note, you will need to check/recalibrate the CV outputs after installation. [ especially if you
are upgrading from V3.21 ]

Let us know if you have any issues with it.
After installing Part A, the Sequencer might freeze, and you will need to restart to install Part B.



New features and fixes:

- RESET INPUT via menu option, using the MIDI INPUT jack [ TRS switch must be set to position 2 ]
- SEQ B ->RESET SEQ A via menu option, allows SeqB to reset SeqA when a gate high on SeqB occurs.
- MIDI 2 CV input channel selection via Rotary Switch, higher resolution Pitch Bend / Modulation CV output.
- Software of sequencer now runs x 4 faster, less latency etc.
- Various bug fixes.
- MIDI INPUT Channel and MIDI Clock DIV combined into one menu item

Please check the attached V1.5 manual, for the new menu settings structure to access the new features.

How do I check the current version of my firmware? Not sure if mine shipped with the latest one (a couple of weeks ago)

Hello

Modules and kits have been shipping with V3.33 for the last month or so, so you should have the latest version installed.
If it is bought new [ ie not 2nd hand ] then the label on the chip indicates the installed firmware.

Currently there is no option to display the installed firmware version.

Hi! A question about the portamento range... it seems like the portamento on mine is pretty conservative, even at full values. Can someone please post an example of what theirs sounds like driving a VCO with full portamento (100%)? Thanks.
