Quantizing already quantized notes leads to a dark portal of mysteries and small voltage offsets.
Add a small +- voltage offset to your input cv and your half step off will be fixed, or migrate.
Depends on how your quantizer rounds up or down when the input is close to a note.

The notes from the sequencer are not already quantized. Its a digital sequencer so the voltages are just precise.
So the fact that just the first note is getting shifted up a semi tone really makes little sense to me.
But I don't build or design modules so thats not much of a surprise.

I have repeated the experiment but instead of using the built in quantizer I used an external one and the sequence plays as expected.
So it does appear to point to some issue with the internal quantizer to me.

Nice business with @bssw, all good! : )

Buying a module carries much less responsibility than selling a module.

There are scam possibilities from both sides. I am dealing with lot's of requests to delete unjustified downvotes which is annoying because I don't want to interfere in private conversations so if someone comes up with a better, easy to implement idea I am all ears.

-- modulargrid

I've been thinking about a system to replace the current up/downvote options with and I think I have a pretty solid idea here. Besides being more reliable, I think this system will also reduce the amount of requests to remove negative feedback.

Whenever a user has bought or sold a module and decides to up/downvote to the other, the user on the receiving end is sent an automated request to return feedback to the user that initiated it. The catch is however, that only after both parties have submitted their feedback, the score is shown. Neither user can change their feedback after placing it.

This approach eliminates any worries about receiving retaliatory downvote simply because a user is dissatisfied with another user. At the same time, if a transaction didn't happen or if a user is being unreasonable, a user can decide to not leave feedback and thus not getting any in return either.

An optional one-time opportunity, in the form of a single non-editable comment, could be given to any user receiving the downvote as a way of explaining themselves. This comment would be shown as a comment on the users profile, for example when hovering over the username of someone who left the feedback. In any case, comments can not be replied to or edited after placing them. If a solution has been agreed upon by both users, there will be an opportunity to change the negative feedback into a neutral feedback and with that also removing the comment from the users profile. In no way however, will negative feedback be allowed to turn into a positive feedback unless submitted by mistake.

Since there are several aspects to this system, implementation can be as simple and straight forward, or as elaborate and complicated as desired. Simply withholding information about the type of feedback left by one user to another creates a far more reliable system than is currently in place and completely eliminates any fear of retaliatory feedback.

I know this system is not entirely fool-proof, but it would be very difficult to pull that off without enforcing transaction verification.

The current feedback score for users can be held in the form of a legacy score in order to smoothen the transition to a new system.

Thanks. Yes, I have started to group CBS and SFTMC with Buchla,
(I've only done a few so far) including images from those early panels when available. 👍

Duplicates and inconsistent listings are always a pain, especially with Buchla clones and obscure modules like CBS or San Francisco Tape Center gear. For those, maybe grouping them under “Buchla” but noting the manufacturer/clone in parentheses could work - keeps them searchable without losing the historical context. Overall, a consistent scheme like yours will make the database way more user-friendly.

I bought a couple of Happy Nerding modules from @Mumdad and was very pleased with their clear and friendly communication and prompt shipping.

I just want to leave a note here to say that dealing with @neuroloop75 has been an absolute pleasure.
He made me feel really comfortable throughout the whole process — and I’m not used to trading here with such high amounts, especially for something like the Morphagene I bought, which arrived practically as new, perfectly cared for, no marks, no smoke, nothing at all.

Thank you so much — you can trust this user completely. He does everything properly, and even if he sometimes takes a little longer to reply, he gives you all the confidence you need to complete the deal without any worries.

Highly recommended!

Thanks both.
I know my ay around the Buchla universe, yet I felt the need to hear other users opinions.
I'm a moderator and will do my best to make it better. It will move slowly though, with some changes every now and then.
I will concentrate on the original modules and the clones.
Cheers

Nothing wrong with running their modules
(though I've avoided getting a space fx, and have those "four" functions covered.).
I've used the Chaos Marbles clone often, way more than the Abacus. I'll never understand the popularity of Maths.

The 1050 mix sequencer would work great here as your output mixer or for getting a 24 note sequence from the 1027,
or just for switching signals. There's also the cable in the back to send the 1027's clock to the 1050, and a switch for it.

The behringer arp and roland clones are on discount now, I suspect that line will be discontinued soon.
I know there's a ton of them out there for the used market, but get 'em new while you can.

You could benefit from a good mult to share your hard-won generated signals.
I like the Synthrotek MST '07 Buffered Multiple @ 4HP. Best $99 you could spend here.

I think you can get lots out of what you've shown here already.

I've moved things around, mostly to help with using those little short yellow Doepfer patch cables.

EDITED Thursday November 20, 01:45

Any ideas as to why I'm getting this behaviour would be cool.

So, if I feed a sequence into the volt/octave input that consists of the “C” major scale ie: C D E F G A B C
it will play that back just fine. However if I turn on the VCO’s built in quantiser, set to chromatic, it plays back C sharp D E F G A B C.
I have calibrated the VCO so it’s not that. I’m completely baffled as to why the first C is sharp.

Don't hate me for being Behringer's b1tch at the moment... I'm a hobbyist dad on a budget.
Here's my rack so far. I don't have the Four Play module yet (awaiting resupply) and the 2HP Tune is in the mail. Excited to play with that when it comes. I also have a Dual VCA module I use for now but is not shown here.
I still have some HP left after those for some cool stuff in the future.
I've been playing with these modules combined with the Arturia MiniBrute 2 and Behringer Neutron and getting some really fun stuff out of it. I'm mostly doing horror drones, industrial and bass dub beats, trip hop and playing around building melodies here and there but there's so much to discover. I'm having a ton of fun putting a few odd songs together.
My big issue at the moment is I would like to sample and loop on the fly but I gotta save up for a more expensive module. Considering saving for a 1010music bitbox to cover that.
Cheers!

It may be buggy then. I'll see if I can find a reproducible scenario.

That's a recent change right? Just checked and it indeed seems to work. Great, I used to literally always dismiss the manufacturer info.

I looked it up, it was commited

But there is always the chance that it is not working right in some browser or a code regression, so report if you have issues.

Similarly, I also wouldn't mind by default hiding the manufacturer info panel either ( which shows up above search results when the manufacturer is set in search criteria).

This should already work. If you hide the manufacturer info panel it is saved in the user pref and should be restored even after a new login on a differen tcomputer.

Buchla a mess? Did recently someone looked in the pedals section?

2. Who is going to do the actual work? (Knut has a day job or two and can't be bothered)

Please bother me anytime, if I can fix stuff I do it. I just have little knowledge about Buchla.

3. What about DUPLICATEs? People are making very poor new module entries because they don't know how to use the Marketplace. Or do not care to.

Moderators can merge duplicates or what is even easier just unlist/hide them, so only the uploader can see them.

4. 'Manufacturer Approved' lock. Even if you know/mean better, you can't. https://modulargrid.net/e/forum/posts/index/13163)

Under the Approved stamp is a link where you can send a message to the manufacturer and tell him he should unlock or update the data.

I will unlock modules where the manufacturer is out of business. Someone has to tell me which manufactureres that are.

Show Blank Panels setting is stored in the DB

If you check/uncheck Show Blank Panels in the modules search form the change is saved in the database. Next time you log in this will be used as default value so you don't have to hide them every time.

Edge Case: if someone messages you a link to a search result with blank panels that will override your setting, else you would not see the panels.

That's right KNYST, it's a big mess and not just about Buchla stuff. Not sure if this can be solved at all. Inconsistency is a trait of the human condition, I guess, and module entries are made by many humans.

An number of questions come to mind:

1. Who is going to decide how things are 'right'? (I find myself having different views over time)
2. Who is going to do the actual work? (Knut has a day job or two and can't be bothered)

I am chasing the specific sound that Noise Engineering modules provide so I am willing to pay premium for it.
-- ModeB

Fair enough, I get that :-)

I would suggest the inclusion of a Voltage Block or the excellent Neo Trinity from Bastl, the NE voices start shining once fed with heavy modulation.
Also, there's a stereo solution for line out offered by Intellijel which is slightly more HP efficient I think.

Hope this helps, best of luck for your musical project !

$2,300 is a lot for a one drum/one oscillator/one filter system.
-- noodle_hut

Agreed, however I am chasing the specific sound that Noise Engineering modules provide so I am willing to pay premium for it.

In terms of the filter/fx/modulator/VCA that I have currently picked, these are probably unnecessarily large/expensive for a rig this small. Open to suggestions :)

Hi all,
I've had my fun with standalone analogue synths and am looking to begin my eurorack journey.
I am looking to build a setup to be used for live performance and studio recording of hypnotic techno/groove.
My current studio setup is centred around using my elektron digitakt 2 for drums, sampling, midi sequencing and arrangement.
I intend on using my digitakt paired with the Mutant Brain to handle all my clocking and sequencing, therefore my ideal modular setup is only to be used as a synth voice and rhythmic noise generator.

I have linked my current idea below, any and all feedback appreciated!

EDITED Wednesday November 19, 22:52

Hello to anyone interested,

I have changed the Buchla modules and clones (Buchla format) to something more consistent.
An example:
Modules made by Buchla (or clones of their output) should be named "Model 123" etc, followed by "Sequential Voltage Source" etc. This way, we can sort them by name and actually find all modules listed of an individual model number.

There are quite a few duplicates. I have taken care of a few as of now...
Another problem is all the CBS and San Francisco Tape Center modules - what to with these? They are in fact Buchla modules, but they are all over the place; some listed as Other/Unknown and some as Buchla.
Same goes for many clones: LA67, I Must Scream, R (RomanF), etc. These front panels are sprinkled everywhere among the listed modules. A huge mess.
If you care, give me some input on your thoughts about it all.

Thanks,

oh yeah, absolutely that’s why I edited my previous post added the last sentence saying "having to turn off option at settings page instead of by account default"

Because there are people who actually runs a company just doing replacement panels. Removing their visibility would affect their business.

i mean it could even be a unicorn account feature.

EDITED Tuesday November 18, 17:52

I can see both sides of this for the sake of manufacturers, if there is to be a default it should be either Both boxes ticked or both boxes Unticked, so we have Show Other/Unkown and Blank Panels.
There is honestly more interesting stuff in having Show Other/Unkown Ticked than the Blank Panels.

I wouldn't mind this option either.

Similarly, I also wouldn't mind by default hiding the manufacturer info panel either ( which shows up above search results when the manufacturer is set in search criteria).

Saving whatever the user chose last could also make sense for these items.

Hello,

I'm looking for beta testers for 2 modules I've been working on.

The first is a clock module ( roboDNA Pulse ) which is a master clock and allows creating and saving complex clock configurations for up to 12 devices. You can label which device connects to which clock and save to EEPROM, cloud or local store so complex setups can be easily re-patched. I have a full iOS/iPAD control suface in the Apple App store and it also has a web browser app via USB. It has an API so can be controlled via Javascript in the browser or from other microcontrollers via SPI, MIDI or USART. It does sub-divisions/polyrythms, up to 4 sub-divisions per each of the 6 clocks. All the control surfaces ( MIDI, web browser, iPad and hardware control panel ) are all synced using a packet protocol ( roboDNA Double Helix ) which can traverse bluetooth, wifi, ethernet, rs485 etc. The modules can be chained and auto-addressed via a 3 wire and the protocol. Each module has 6 clock with 2 output for each. ( 12 clock output total ) It has bluetooth for studio/home and USB for live connections.

There are several other features baked-in and have the full user guide and API Reference guide at https://roboDNA.com

I'm not a musician and am looking for real-world feedback to compliment the simulations I'm running for testing. I realize not many mucisicans require all those clocks and clock features, but hoping I can find some here. If anyone is interested in helping BETA test, please PM me.

P.S. I also have a sequencer module ( roboDNA Sequence ) which is my main project and will need BETA testers for that as well.

Thank you

Superb!

Maths sure takes up a lot of room.

Monsoon + Disting might be a challenge to control using what's there.
When I've run them in serial, the details turned mushy and high end gets lost,
but I like that dual filter. It works well as a mixer with three inputs on each filter,
so maybe those three will be interesting together.

The usual next step, the boring things; active mults, attenuator/offsets, CV mixers,
maybe a quantizer if you're doing note-ey stuff.

That set should be fun.

Looking for advice on my first rack. I put a lot of thought into it but I'm still very confused until I get hands on with this stuff, so I am seeking advice/opinions.

So far I own Maths, Monsoon and Beehive. I will be sequencing externally and can get drums externally but I did add the Expert Sleepers to the build for drums in a pinch and also the many other things it can do. I'll probably be using my polyend tracker for drums and sequencing via midivolts 4 channel cv/gate and clock output. I also have a few other things I could use if needed but I love my tracker and would be the preferred device.

My end goal is to have something to make spacey ambient stuff, and sounds and melodies I can sample for hiphop and electronic music production.

I have a B2600 I will be using with the rack for a while as I build up my collection.

I am getting my amp and mixer next. What modules should I be looking to get afterwards?

I would like to expand to a 6u build at some point.

I just received mine. When I plugged it up, it was making a hideous screeching noise. But in less than a minute, just playing with the knobs (not even knowing what they did), I had it making a beautiful dreamscape. This is my new favorite module and I think I might create a 3u /104 hp system just supporting it.

Has anyone processed external audio? That's my next adventure.

This module is awesome!

Yeah, I have Delta-V in there because I didn't have any module in mind at the moment. They definitely overlap. I like Maths better, and it'll be the one that stays, even though it takes up more HP. If I had at least the V2 of Delta-V that might have won over Maths, though, since that would have a sum out, as well.

I was thinking of adding in Ornament & Crime with the Phazerville firmware in place of Delta-V. It adds a lot of utility and modulation, imo.

I do like the A-118 for noise, but could probably get better use of the HP and get noise for cheaper. 8HP for a noise generator is quite a bit, and I can reduce that to 2HP.

Thanks for the suggestion on Clouds. I know the FX Aid does grains now, but I really do love the distortion and sample rate reduction on FX Aid in addition to grains. I have the modules already, so I'll give it a shot with removing Clouds from the chain and see how that works out for me.

If I do get rid of Clouds and with the savings of space from the A-118 to a smaller noise generator, that would give me enough room for Marbles (or at least Pachinko).

I'll probably be using my Digitakt for the majority of the drums at this point, though. Even though I've been using my KeyStep as my main sequencer and leaving the Digitakt out of it.

Thank you for the suggestions. I'm already making some changes and gives me a bit of thinking to do with a couple of other modules I could swap.

Just a short note that RackDocs 1.4 is now approved by Apple, and it comes with some requested features and changes:
- Three new annotation types have been added!
1) Fader for linear slide controls with optional LED illumination support
2) Card Slot for documenting SD card slots and sample storage
3) Joystick with full 9-position state documentation covering all eight directions plus center

Then the knob documentation has been enhanced with an "Encoder Type" checkbox to distinguish rotary encoders from regular knobs. Encoders now display with a distinct icon and are properly labeled throughout the app, which is particularly useful for modules with pushable encoders for menu navigation.

All icon designs have been refreshed for better visual clarity.

By the way, the last version 1.3 brought beautiful export and sharing features for Cheat Sheets.

As always, feedback is more than welcome. If there are annotation types or features you'd like to see, let me know.
