What is the recommended DB-25 cable length?
thanks,
Luke
Hi,
We currently use this one from Reichelt:
TK. suggests up to five metres would work.
So I guess that means 16 feet in Freedom Units. Unfortunately I couldn’t find a decent one from Mouser but if you need to get all of your parts there, 571-1658613-2 plus 26-way ribbon could do the job (and would be less bulky than a cable). Another famous sequencer does it that way :).
Hi,
Is it possible to connect the CV/Gate modules directly to a Mios Core?
I have already two LPC_17 Cores inside my modular for midi processing/distribution. It would love to use these new Eurorack modules but i cant afford a complete miosSEQ4 build right now.
thanks Paul
Hi Paul,
The modules should be compatible with all Core versions. The digital gates etc. were typically done with GPIO pins for older Cores.
Best,
Andy
Hi All,
I am breaking my head to get a lfo out to a cv port. I read the forum and this question has been answered earlier but still i don’t understand. I am creatng a new CC track on AOUT channel 1 , i init the track and set FX -> LFO to on . I am wondering what the next step will be because whatever i try nothing happens with the CV on channel 1. Do i have to put the CC value to something on the track? I also read the manual but i am stil stuck.
Many thanks!
Niels
Hi Niels,
I am also confused, tried the other day with to get an LFO going but I don’t know how.
It would be interesting if you could get it working with a regular CC or MIDI note track then try to change the port to AOUT. Maybe a few notes are needed in the track?
Sorry that I can’t help!
Best,
Andy
Evening Andy,
Too bad, i thought it was something simple to fix. Yep tried notes, different CC values. It should be possible to implement because when i go to the CV calibration screen and set the calibration to wave then i get some kind of lfo and this works but not suited for my purpose ofcourse 
Cheers!
Niels
and just had a look in the code to see what is really going on in seq_lfo.c - as a short conclusion, if a “note lfo” is used, the lfo value is rounded to an integer value between 1 and 127 to reflect a MIDI note - so even if this was put out via AOUT, that is probably not what you would want in a CV scenario (a more or less “stepless” continuous LFO waveform). Probably it would be best to ask TK. in the main SEQ V4 thread for a CV LFO expansion with non-note-steps, if possible, we’d also vote for that expansion, of course :)!
Best regards and have a nice weekend!
Peter
Thanks Peter for checking this out. I will post a request for it
Have a nice weekend/beer!
Just to finalize my question about lfo. Thorsten gave the following tip that works like a charm.
- assign track to CV
- in LFO page, set the ExtraCC# to 16..23
16 will send to CV channel #1, 17 to channel #2, etc - which means: with the CC number you can address the CV channel you would like to use as LFO output
Very happy with this feature since this saves me on buying a special lfo eurorack board ;-)
Hi, would it be an idea to put the panels on modulargrid with power consumption etc. My rack over there is so empty without the midiphy panels. Do you have an idea of the power consumption?
Hi Niels,
It’s a good idea, I will look into it!
Best,
Andy
Okay, you can add them now!

Cool thank a lot!!!
Hi, last week I finished my eurorack modules and they seem to work fine now. At first they (clocks and gates) started normal but after a few seconds they started to add randomness. In the end I found out I hadn’t soldered the db25 connector to the board,.. stupid!
The calibration feature works really nice and handy!!! I managed to get a good tracking over at least 7 octaves on my sh101.
But…
When I switch to Hz/Volt, for controlling my korg ms-20 I get a really strange output, I get the complete range of 4 octaves under 1 octave of my keyboard. Am I missing something, does the Hz/V has its own calibration, or isn’t Hz/V implemented yet?!
What voltages do you read out of the output with 1/2/3/4/5 V… or min/mid/max?
Looking at the MS-20 manual, it seems to expect a linear 0-8V CV for the VCOs? So maybe normal V/Oct scaling is already good? If you really need to work within the positive range, remove the offset resistor on any channels you would like to use in unipolar mode. These resistors xR34,xR35,xR36x… etc. are listed in the BOM on the transmute8 page.

After calibration I got as close as 0.998V 1,997V…9,999V, so that seems working reallly good.
I didn’t check the manual, but I’ve been using my ms-20 for over 20 years, and have been using it with different midi2CV converters and always needed to select V/Hz instead of V/Oct. I also used it on my ‘old’ SeqV4 with build in Aout board and that always worked good with the Hz/V setting in the CV configuration. There is a workaround for using V/Oct on a Ms-20. You put the bi-polar CV signal into the Ext Freq input, and turn the corresponding pot to around 9 'o clock. But it’s quite hard to get a good stable tuning over multiple octaves this way.
I’ll try to remove the resistor and make a unipolar output and see what that does. If it’s only offsetting the CV value I can’t imagine that it will scale alright, but I’ll try and let you know
Let me check first if something can be done at the SW side (tomorrow…)
Best Regards, Thorsten.

I will!, and I’m not on a hurry so if it isn’t tomorrow, no problemo, thanks anyway!
I added some code which should allow proper calibration of Hz/V - could you please check at your side?

Note also: by pushing the GP7 button in CV page we can now switch to bipolar voltage display, which is a bit more convenient
