not possible for note events to trigger scripts, and translating notes is only possible when faderbank is in leader mode. there could be a mechanism implemented where you could poll for notes but then yes, it would be limited to your metro rate (or as you suggest you could trigger scripts from gate out).

can anyone help me source the buchla / deckard style caps in the US of A?

cheers

16n is a bank of faders [release thread]
#104

Mouser has some by nkk and mountain. I’ll have to search for part numbers.

EDIT (mountain part numbers here for @sisyphus69 ):
I found this reference with these part numbers:
10TB001 RED
10TB002 BLACK
10TB003 WHITE
10TB004 BLUE
10TB005 YELLOW
10TB006 GREEN (not available)

I also bought some of these (which broke apart when heated up - but otherwise are a very tight fit):
108-00365-EV YELLOW
108-00357-EV BLUE
108-00323-EV RED
108-00341-EV WHITE
108-00332-EV BLACK

I got mine here:

And my 16n arrived today (Thanks Raph! @MichiganSynthWorks) and they fit great.

oh nice synthcube is stocking those now!

A friend is putt one together and I wondered if anyone had any suggestions of where I could get a hold of metal front and back plate for this? Did everyone just DIY their own one and cut them out at home?

#108

There’s a Group Buy thread with additional info.

I had 1/8" aluminum laser cut and had some for offer. I’m all out of the first run right now though. I’d need at least 2 confirmed orders to start another order. ($60 per set + shipping)

Note - I’m not going to offer finishing on these - so it’d be raw aluminum as it comes from the laser cutter and it needs edges sanded and finishing. I suggest this SYNSI article for home finishing.

#109

Almost certainly not! Metal plates tend to have been made by machine shops or small-scale manufacture places. (Metal is challenging to laser at best, too). The sample images of mine you’ll have seen have metal panels from Fahrion in Germany - they were about $80 a set for 5 - for top/bottom cut then anodised. If you anodise before cut, you’ll get raw edges, which aren’t so attractive.

Grawart in Poland are sometimes used by DIY heads and the panels I got from them for another run were good, too. Alternatively, Front Panel Designer files have been made by someone in a thread, so Front Panel Express might be able to make you some.

But basically: people have taken panel files and either cut their own at fab spaces, or had small runs manufactured.

In the states I had my top and bottom panels cut by Ponoko, which I’ve had laser cutting done before for my modular case(same bamboo except 3 ply). I made 9 sets of top and bottom 1 ply .106" thickness Bamboo, they came out great! However, the file I used used the outer edge for the countersunk hole for the mounting holes, which left the mounting holes quite big, I got around this on the first prototype with M3 standoffs and countersunk screws which luckily just barely fit. Still waiting on fader caps arrival, which I found to be cheapest on Ebay, but heres a mockup with the bamboo unfinished and 20 year old Behringer fader caps for the time being. Thanks to everybody involved!

Having some trouble getting my 16n and the ER-301 to cooperate. I wrote a longer description over on the OD forum:

https://forum.orthogonaldevices.com/t/16n-faderbank-is-happening/2461/98?u=iiii

Hoping maybe someone over here might have an idea too. :pray:

#112

Everything looks ok to me with your setup.

Easiest bet would be to unscrew/remove the top plate (it’s just 8 screws) and check to be sure you have resistors on the i2c bus.

If the pads (marked DNP) on the outside of the diodes are empty - like this photo - then you’re missing the resistors and i2c won’t work directly with ER-301.

Bummer. But at least I know what the problem is! Thanks!

:frowning: send it back to Raph.

#115

Very cool stuff. Wondering if you could point me in the right direction for making these changes for ER301 and midi though. I’ve sifted through your branch on github, read up on editing the firmware to enable, and I’m still having trouble.

I grabbed the arduino software, and added teensyduino, but am unsure how to proceed. I still have a copy of the 16n master hex file, but I’m unable to open it in the arduino editor. Am I on the right track, and what am I missing?

Thanks!

#116

the hex file is only for loading - you can’t edit that.

you want the file _16n_faderbank_firmware.ino - open that in Arduino.
Then connect the teensy with a known good DATA usb cable.
Then you have to set the correct things in the Tools menu
Tools->USB Type= MIDI or Serial+MIDI
Tools->Board = Teensy 3.1/3.2
Tools->CPU Speed = 120mhx (overclock)

Then hit the program button (looks like a right arrow)

#117

Ok. I followed your instructions.

I found and downloaded the .ino file.
I connected with the same usb cable I just bought to update the 16n.
Made the proper settings in arduinio, and hit upload (right arrow icon)

Then I got an error msg ‘stray ’ \302’ in program, but I went ahead and tried to test it with ableton and ER301 with the i2c cable connected to my txb. I did all the typical enabling in Ableton’s midi prefs, set the track to output on channel 1, and scanned through all the ports on the SC CV unit on the ER301 and all the midi channels in ableton. So far, it seems I’m not having any luck.
stray '\3.

#118

It’s worth mentioning, when plugged via usb into my computer the faders don’t seem to transmit on their corresponding ports (1-16) but they still do if power the 16n from a regular usb wall plug.

Edit: Also worth mentioning I’m on an older version of aruino for mac. The latest, and the hourly build both crash on startup. Will try updating from another computer later today.

#119

Well this probably means it did not properly flash the teensy. I have no idea what ‘stray ’ \302’ means without any other context.

Can you try that again and copy the entire text from the arduino window (bottom section should show a bunch of red text if there were errors).

EDIT - it would also be good to know the source or your build (either yourself or someone who built it for you).

EDIT 2: Also also - does the 16n work normally/as-expected when flashed with the release HEX file?

#120

16n from Michigan Synthworks. Same message on 2nd try. If its ok, I pm’d you the error message as it is a wall of text.

Just saw your edit. When plugged via usb into my computer, no it doesn’t seem to send fader info over i2c. When plugged into the wall instead, it works normally.

At the bottom of the aruidno window, the following line is highlighted in red:

16n/_16n_faderbank_firmware.ino at master · 16n-faderbank/16n · GitHub
#121

Ok, so I finally got around to building mine, and I’ve run into a couple problems.

I’ve double checked the solder joints and gone over everything and things look ok, but not super clean given how small stuff is.

At the moment I’m having two problems. The first is that none of the faders go above 95, like none of them. According to the build guide this could be due to the voltage being divided too much, except here it’s happening to all the faders, not just a single one.

The second problem is that some (3) of the faders aren’t going down to zero. So those three are going from 58-95. I’m guessing voltage stuff as well, but would the bottom range correspond to a specific resistor(s)?
