Nsynth Super

desolationjones · 2018-03-16T11:34:01.385Z

The Nsynth Super is just a Rasberry Pi wave player playing prepared files. The real magic is in using a Linux server with TensorFlow to bake out the wave files which morph between your input sounds. That is not possible (yet!) in real time on a RPi. Has anyone played around with the software to make their own sounds yet?

Pretty sure it’s not going to be realtime anytime soon. TensorFlow is sometimes called TensorSlow for a reason.

I priced the PCB at OSHPark, it looked like $198 for 3 boards, and the drill-pattern slots probably need to be redrawn. Curious if you can do better. (Also, hello Burlington! In Boston, but spend a lot of time in VT.)

It’s disappointing that the open-source version doesn’t have the same graphical touchscreen as the demo videos. That would be a fun platform to build on. An off-the-shelf touchscreen probably wouldn’t increase the cost or complexity too much, but I suspect they wanted to publish a design that could be built and extended for a while without needing to be adapted to whatever inexpensive touchscreen was available that week.

I’m still strongly considering building one! And maybe adding some CV or i2c inputs.

I am on this coast too jeffrey-- we should congress at some point

I sent away for a few quotes - I’ll be get back to you with pricing shortly. If a number of us on this thread are planning on building, maybe we cast our lots together to cut down on costs? In addition to the PCB, even some of the components (like the USB socket) require minimum order numbers. Raise your hand if you are interested in getting in on group/shared orders and I’ll investigate how our combined efforts might work out.

$20 PCBs on Tindie: https://www.tindie.com/products/squarofumi/nsynth-super-pcb-googles-ml-synthesizer/

I’d be up for a group buy!

jeffreypierce · 2018-03-18T23:58:00.498Z

Great find! With this pricing - I don’t think we’ll need a group buy. This website also had a link to all the discrete and SMD components for ca. $36. I just ordered the board and all the parts. I’ll send pics (if anyone cares) as soon as I receive it all.

amandwato · 2018-03-19T15:46:51.374Z

would you have a link to purchase all the components?

jeffreypierce · 2018-03-19T17:22:05.813Z

Here is where I purchased everything and rough costs (no shipping, tax, etc.):

Raspberry Pi (and friends)
- https://www.amazon.com/gp/registry/wishlist/3BLOLN4D6OG8C/ref=cm_wl_huc_view
- $88
OLED Display
- https://www.adafruit.com/product/938
- $20
PCB
- https://www.tindie.com/products/squarofumi/nsynth-super-pcb-googles-ml-synthesizer/
- $20
Components
- http://www.digikey.com/classic/Ordering/AddPart.aspx?WT.z_cid=Shared_Cart
- $36
Parts
- I either have something that works or a trip to Lowes?
- free - $15

Hope this helps!

Tindie is also now selling semi-assembled boards for $60: https://www.tindie.com/products/squarofumi/nsynth-super-semi-assembled-googles-ml-synth/

Is anyone keen for a eurorack friendly respin of this synth?

ericmoderbacher · 2019-03-05T21:53:49.810Z

I would love to see a supercollider or pd implement of the Nsynth. I recently bought the super collider book. It’s been fantastic, if I take to supercollider well enough I’d like to try to play around recreating the nsynth as a ugen.

Has anyone built and setup one of these?

I’ve got two built but unfortunately when I get to the “make install” portion of the instructions I get an error and I cannot proceed.

If anyone is handy with linux or has gone through this already and can give someone a bit of help I would very much appreciate it.

I built mine a couple of years ago. I don’t remember any errors with “make install”. I used the 64GB image (with the sound library) SD card:
64GB (with sounds) https://storage.googleapis.com/open-nsynth-super/images/onss_1.2.0_full.img.bz2
16GB (without sounds) https://storage.googleapis.com/open-nsynth-super/images/onss_1.2.0_lite.img.bz2

As I remember, you just have to record the image in the SD (via Etcher), put it in the raspberry and enjoy!

corpusjonsey · 2021-03-03T15:55:33.973Z

If anyone has an interest in one of these I have 4 built boards without RasPi’s. If so, I can make a BST post.

adnauseam · 2021-03-04T07:11:23.867Z

So you’re saying that the image I installed is already setup and running the nsynth software? I’ll check it out! If so I will be very stoked

raw · 2021-03-04T07:26:42.853Z

As I remember, yeah.

They are two different paths. Build your version of the software or download and save the image in the SD.

I followed the steps in this guide (GitHub - googlecreativelab/open-nsynth-super: Open NSynth Super is an experimental physical interface for the NSynth algorithm). Regarding software, it only indicates:

record the image on the SD
run the script for the controller.

If the error is when running the script for the microcontroller, paste the code and the error here. I keep an eye on it.

adnauseam · 2021-03-15T20:06:16.221Z

raw:

run the script for the controller.

So I copied the 64 gb image to the card.
Logged in
Made the filesystem read/write
Tried to do the “make install” step as shown in the next step and that’s when I get an error.
here’s a screenshot as it was easier

I was following the same instructions as the page you shared. I have tried connecting a midi keyboard and sending the rpi notes but the display does not turn on. I suspect because this last step has failed.

Any help appreciated!

Try

sudo make install
