Hello It's done!

Dear Ralmslb when the fader is moving you can touch the knob and the movment stops immediatly allowing you to register new automation with your finger. This not because the fader senses an obstacle but because it’s sensitive to touch. Having said that if the fader is moving fastly it might be a bit difficoult to catch the knob with the finger. Probably the solution is to pass to proximity sense… let’s see if someone is interested in testing….

Yes but at the end i still think i2c is the best solution so probably i will change it again. Thanks for your input.

Scratch question 1 - just saw your GitHub!

Hello, thanks for your kind words. The stand for the motorized faders is something I have designed with fusion 360 and printed with my 3d printer. Cheers!

Hello, happy to see you found my project interesting. They do a bit of noise but not too much, in particular I'm using a motor control that works over 20KHz so that the typical PWM motor noise is over the audible threshold. You can use whatever device you want as long as it has a linear potentiometer and a DC motor, I know for instance the 100mm model I am using is available also in a more compact format 60mm. Cheers.

@@fcampanini All of that is very good to hear 😁 I've often thought of making a dedicated motorized ADSR section of a midi controller that would update as the soft-synth is switched, and full size mixer faders seem like overkill. Thanks for the video and reply ✌️

Hello QL Of Landfill, well even starting from the principle "always true" that in everything is possible, I see what you are thinking about quite challenging ;-). It is in fact indeed true that the analog treatment of the signal, like you have in your R16, can be in theory coupled with digital MIDI based circuitry, but that would require a deep modding of your unit to fit the digital MIDI PCBs and components... think about the motorized faders for instance. If you are interested in having the possibility to store and automatize your mixing scenes and still stay in the "standard" mixer domain, I would suggest you to look for built in solutions. There are a lot on the market nowadays. If you like Allen & Heath for instance, they offer quite amazing solutions such as the SQ5. I hope it helps! Cheers!

@@fcampanini thanks man! Yea I was looking at even an old command 8 for this. Would be nice to be able to upgrade the board I have to do everything I need but in the long run probably would make a lot less sense with the amount of money and time I'd have to put into this. Thanks a lot for the answer!

Hello Jamie, if I got your question properly, all info are coming from MIDI message the Makie Universal protocol is made of. Cheers, Filippo

Hello Aaron, I think that i have bought from ebay. I don't remember the dealer but it should be enough for you to search metallic or conductive knob and you should find it.

Hello Cristian, first of all I'm not using Arduino. I am using SAMD11 microcontroller on a PCB that i have designed (you can find the board design and the BOM in the comments of the video). In order to program the microcontroller I am using Atmel Studio IDE, Atmel Start configurator and ASF4 framework. In terms of how many faders, my goal now is to fulfil the Mackie protocol and achieve 8 faders plus the master (so 9 in total). The motorized fader I'm using is a Bourns PSM01. Hope to have answered your questions. Cheers, Filippo

Hello Sonic, I dont know this consol but I guess that if we are talking about motorized faders you need to identify power of the DC motor and +,- and line for the potentiometer and that’s it. At the end of the day the fader I’m using in this video is a device with such kind of connections. Cheers!

I think that with some limit it is possibile, however the reason why you can’t properly communicating with your DAW is not easy to say.

Well yes, kind of…

Hello, although it might be an interesting modding the issue that i see is that you have to find the physical space to fit into your machine motorized faders and digital circuitry to set it up. So IMHO it very much depends on your unit.... Let me please know if you succeed! Ciao!

Please check my Q&A video out! Thanks and cheers!

At the end the first action is about matching the position of the fader and the position communicated via software. But there are offset to be considered to manage oscillations, there is a subject of speed of the adc and of the data transfer via dma and I have recently developed a logic of acceleration when the pot is far and deceleration when it gets close that helps in the quality of the result.

Ciao Riccardo, in questo video sto usando una scheda di prototipazione Nucleo-439ZI con una shield MIDI in formato Arduino www.robotstore.it/Shield-MIDI-Arduino-compatibile. In pratica la Nucleo è collegata alla shield via UART e la shield poi esce con i connettori normali MIDI a 5 punte. Nel video intitolato DIY MIDI Remote Controller Full Strip che trovi sul canale (dove mostro una implementazione più evoluta) invece collego direttamente il Microcontrollore via USB al PC e comunico con Cubase via USB MIDI. Spero sia piu chiaro. Un saluto.

@@fcampanini Ciao Filippo :-) Grazie per la delucidazione. Sto lavorando ad un progetto piuttosto complesso. Ti chiedo se possiamo attivare una chat. Ti ho inviato la richiesta d'amicizia su facebook; in tal modo sarebbe posibile utilizzare la chat di MSN. Anche per eventualmente inviarti documentazione. Grazie e Spero a Presto. Riccardo

I did 4. Feel free to check into the channel… Cheers

Hello, the project uses the Mackie Universal Control Protocol which is de facto a standard for DAW communication with remote surface controls. Mackie Protocol is MIDI based. So via this protocol you can connect your Protools with such devices. Then about "plug and play" these faders are connected with a Microcontroller via UART, and that microcontroller is connected to the PC or MAC via USB so in this sense it is plug and play. Finally about naming the driver the way you want, again you can do this in the USB implementation. I suggest you to check a couple of other videos in my channel such as the third of the motorized fader series in order to understand how the motorized fader is connected to PC or MAC and the video series dedicated to USB to understand better about how this communication standard works. Hope this helps. Cheers

@@fcampanini yes I’ll have a look for sure! Very good

And do you have to upload any code to the fader chip itself? Or just the ST board? Hoping you can provide some insight, as I've otherwise got this ready to go.

Hello yes of course you have to upload the code you have in github in the samd11 you use for the fader.

@@fcampanini So to confirm - there are 2 separate uploads - One for the SamD11 Chip, and one for the Main Controller? I'm not seeing which code is which. How did you connect a USB port to the PCB that you developed? Thanks!

Still a bit lost on how to connect the RST SWCLK and SWDIO pins. Are those the same as the D+, D- and IO pins on a micro USB breakout board??

The one you find in github is for the SAMD11 (the fader). To upload this code you need a programmer debugger such as the Atmel ICE for instance. I have not released the code for the main board (Nucleo-F439ZI) cause I'm working right now on a full console main controller based on a SAME54 (so you will use the same programmer debugger and process as for the SAMD11). However if there will be more requests I will try to publish the one for the Nucleo.

Hello Eitan, in the case of this Video I'm connecting to the PC via Nucleo-439ZI and a MIDI shield in Arduino format. The Nucleo communicate to the shield via UART and the shield is connected via standard 5 pins MIDI connectors and translate the MIDI messages from the UART to the standard MIDI protocol. If you check instead the video DIY MIDI Remote Controller Full Strip on the channel, you will find a more evolved implementation where I'm connecting the microcontroller to the PC directly via USB and then i communicate to the DAW via USB MIDI protocol. Cheers.

Hello you can find these motorized faders for instance at mouser or farnell… these are quite common…

@@fcampanini very cool, thank you for the two adresses, big thankk!

Hello it’s a stm32f446ze from st microcontrollers. Cheers

@@fcampanini You've done some amazing work with this. I just ordered some of the blank PCB's from jlcpcb, but I didn't order them with the SMT parts - Do you think it's possible to hand solder those chips onto a blank board? Thanks, - Zach

Hello I never order assembled pcb. I always manually solder. So yess it is indeed possible. If you never soldered smt just check some of the tutorials on you tube... you will surely find your way! Cheers

@@fcampanini Awesome, thanks so much! Again, incredible work with this. You've done the music tech community a tremendous service by releasing all of this info!

@@fcampanini Is the circuitry on the breadboard related to the midi controller, or is that for the camera?

Hello Krzysztof thanks for being interested in my project. I sent you my details on your email address you shared in the first request. Cheers.

Hello, the protocol used is the Mackie Control one and so forth the possibilities and limits are the ones provided/imposed by it. In terms of channels I guess it’s nominally 8 per midi Channel. Mackie provides solutions with 8 channel in the basic configuration of their controller plus other 8 additional with the expansion. Cheers.

Hello good enough, you can reach me at fcenginering@gmail.com. Cheers.
