A Handy thread to throw interesting bits of tech on…
I bet it gets abused and re-purposed within five posts or doesn’t even get to that number…

This is way cool. I used to do this sort of thing in Basic…
Here’s an interesting new synth idea called “ALT” with an old “pin matrix” (like the EMS Putney VCS3) twist from French manufacturer Cyma Forma:

I don’t know if this post will qualify, it is admittedly a stretch:
On the BeagleV-Fire board, which could be an “interesting device” in its own right, but since it is RISC-V based can’t run Zynthian, yet, there is a connector labeled syzygy on the back of the PCB. Looking for what that is led me to the web site - so basically it seems to be an open standard, maintained by a company (or person?) named Opal Kelly, mainly oriented towards connecting relatively high bandwidth devices to an FPGA, which does make sense because the PolarFire cpu chip on the BeagleV-Fire board does provide an FPGA as a distinguishing feature in addition to four RISC-V cores (5 if you count a “monitor” core).
What did you bet?

Hi All,
I found a very nice wavetable (GitHub - FigBug/Wavetable: Wavetable synth) synth and compiled it for my Zynth. It uses quite some CPU load so do not load to many other stuff or overclock your Zynthian. I asked the creator whether I could distribute this compiled version for aarch64/Arm8.
Happy experimenting:

That’s five.
Ow… editing via: http://zynthian.local:6081/vnc.html?autoconnect=true&password=opensynth
The made presets are accessible via the Zynthian interface. 
Cheers and enjoy,
Maarten

Well, i see all the presets in Zynthian. And the parameters, too. I’m not sure but it seem they appeared after i saved a preset after loading it in Webconf.
Great sounding synth! The basses are so deep. It’s very CPU-hungry but it works.

Yes… a very nice synth! Happy you like it.

Got to love the ambiguous licencing terms…
“The synth is BSD licensed. However, it depends on JUCE. To use in a commercial application, you must have a JUCE license. Wavetables have their own license.”
Back to the “Is zynthian a commercial application because you can buy a kit?” question.

Hi @Baggypants,
I think the sold hardware kit is a commercial application and the hardware design and software is open-source (= free and no license issues).
But then again, I am no Lawyer 
But I am sure there is someone who is knowledgeble in this field in this discourse.
Cheers,
Maarten
That’s why I described it as “ambiguous”. That’s the thing with these “I am not a lawyer” suggestions. There’s no guarentee if the makers of JUCE took Jofe to court that a Judge would see it in that way at all. And the costs involved, even if it was settled out of court, would effectively kill the hardware side of project.
I’m not here to argue against its inclusion in Zynthian, but I do want people to be mindful of the assumption “If it’s on Github, it’s free.”
If I come across as cautious it’s because I’ve seen spurious litigation take down a project I’ve worked on before. On Atari vs. Jeff Minter | Revert to Saved: A blog about design, gaming and technology
I was one of the people who contributed to the original soundtrack of TxK.

Hi @Baggypants ,
Thanks for your comments!
I’m only posting here what I find interesting and would like others to know. They can then decide for themselves what to do. I can’t assess the legal aspects, but I think it would be a valuable addition to the Zynthian software.
Do you think I should stop doing this?
Cheers and thanks for caring!
Maarten
What I do not understand is that if JUCE is dual licensed under AGPLv3 and you can publish plugins made with it under GPLv3, is the Zynthian project then the user of a free open sourced GPLv3 licensed plugin or is it the distributor of the source code of a GPLv3 licensed plugin plus the JUCE source code licenced under whatever the revenue of the Zynthian project allows within Juce’s commercial license tiers? And does it matter if Zynthian would include the precompiled binary or does provide the source code to compile afterwards?
More a hypothetical question though, because a) Zynthian doesn’t distribute it rn and b) the plugin is BSD3 licensed. And any user here would certainly be able to compile it anyways.
If Zynthian chooses to use the AGPLv3 license, then the entire derivate work is licensed under AGPLv3. GPL, LGPL, BSD, MIT, etc. are all compatible with AGPLv3, so code with these licenses can be “dual-licensed” to become a larger AGPLv3 derivative.
In this context, the statement and the question are misleading. JUCE does not require commercial applications to have a JUCE license. It requires proprietary applications, i.e. derivative works that cannot be licensed under AGPLv3, to have a JUCE license.
My understanding is that Zynthian OS generally allows for this kind of relicensing (with a few open questions like linuxsampler license implications). So JUCE most likely won’t have an issue with Zynthian, at least not for being a commercially sold product.

Hi @jofemodo, @riban and fellow Zynthians,
Gents, I am not sure where exactly to adress this item… but I requested the surge-synthesizer team whether they would consider to make their wonderful Shortcircuit XT sampler available in LV2 format so we could use it in the Zynthian. They replied very fast and were very willing to think about possibilities. Unfortunately I do not understand everything that was replied so I report it over here. What do you think and what is possible?
Perhaps a CLAP wrapper would already provide a solution. (In addition, the world of useful plugins would expand, as many new plugins are being created for CLAP.)
What do you think?
Here is the link to the very brief discussion with the surge team:
Cheers,
Maarten

Recently spoted this one randomwaves
It’s open source and I like what they did, it’s packed with a lot of features.
