Ok, which program did you load inside the MF tool? Mackie protocol or something else?

 

Which fader did you touch?

 

Are you experiencing any problems when you move the fader you touched? Like the motors preventing you from moving the fader?

 

Are you using a laptop? If so, are you running it on batteries or on a psu when you are using the MF module?

 

A lot of questions, I know. But answering them could bring us closer to a solution.

 

my regards

This was with mackie control, I get a variation of the same thing for the other types too.

I touched the first fader.

When I move the motors fight me if I have a DAW program up. In mios studio, they don't fight.

I am on a MacBook Pro. I have used it on battery and wall adaptor psu. No change in behavior.

Hi Nick M

Did you ever tested your faders with the Mios Studio MF_NG Program? It seams to me that the motor is inverse or the 0%/100% Pin is miss connected to Wiper. 

Test the two buttons top and bottom. If the fader goes up and down and up again it wold seam to me all right...

Here is a Connection diagram: http://dl.dropboxusercontent.com/u/29658831/midibox/MF_NG/MF_NG_connection_diagram.pdf

Check if the connections are right and be aware that the motor has to be on top. If you whant to have the motor botom sided you need to inverse both. Motor A/B and 0%/100% of your fader...

best regards

I have gone over this many, many times.  

All my wiring is correct, this I am sure of.  I cannot get rid of the  constant stream of on/off when I touch a fader.  It recognizes the correct fader, stops the stream when I release.  

 

The faders seem to work fine if I disable the touch sensors.  I just don't like how loud or choppy they are.  I don't fully understand the settings in the mios tool.  I cant seem to find a setting that would be acceptable.  They are all just different versions of ok at best.  What do you guys set your calibration settings to?

Probably the "Touchsensor Sensitivity" is too low. I think that 3 is the best value. Change it - and if it works, push the "send" button to ensure that this configuration is permanently saved (and will be restored after power-on)

 

 

 

The faders seem to work fine if I disable the touch sensors.

 

Once you get the touch sensors working, I strongly recommend you to select the touch sensor mode which ensures that no fader event is sent as long as the sensor is not pressed (last option)

 

 

 

I just don't like how loud or choppy they are.

 

General hint: than lower the motor voltage (can be adjusted with P1 on the MBHP_MF_NG module), than quieter the faders.

For Alps RSAON the default Duty settings (48/64) are ok for both directions. PWM Steps should be 64.

These are the default values...

 

Adjust the motor voltage, starting from the lowest value, increase the voltage until all faders are moving and don't get stucked.

The "Slow Sine" testmode is very useful for this procedure.

 

Best Regards, Thorsten.

Hey,

 

I set up my motorfaders and try to get the touchsensors running. For testing I use just one fader and limit the numbers of faders in to MF_NG tool inside MIOS Studio to 1 to not get any jitter values of the open fader-ports.

I connected T0 of the PCB to the touchsensor of my motorfader (ALPS coreless 100mm 10k lin.), GND to GND of the motorfader. There is nothing happening... even if I disconnect the touchsensor-cable I would expect, that I get a lot of random values, because the touchsensor port is open and not connected to anything. But: The monitor says nothing. 

 

It also doesn't care which fader-mode I use... same with touchsensor-mode and touchsensor sensibility.  

 

Well, it's late now so I will give it a fresh look tomorrow. But any tipps are welcome :)

 

Thanks,

Chris

Nice! i also did the hole thing in a similar way once. But unfourtunately i didn't get so far to test it completely until now.

Im currently making my page new. After that i will be able to provide all designs as Eagle file an lib... as opensource. Just give me a month or two...

 

 

If anybody is interested in beta-testing i have a spare unequiped pcb (foto) to give away.

Hey people,

 

for those of you who are using motorfader with a 4pin connector I created a PCB. 

 

6pin connector Fader_01, Fader_02, is going to the 4pin connector on the fader plus two cables for the motor.

2pin connector Motor_01, Motor_02, etc. is going to the MF_NG pcb. 

J1 is going to J2 (analog inputs).

J2 is going to J14 (touch sensors). 

 

Because this one is a single-layer layout, you need to connect the vias. I named the signals in eagle (use the info-tool).

Hey Guys, havent been here for a while now. Projekt runs Great will Update this in the next weeks i promise. I am just struggeling with the Motorfaders ATM. Turns out it is a Problem for the Midibox to accept Movements of 2 Faders at the same time. 

 

First my Conifguration of MF_NG Modules: Ive got two of them in a chain which are connected to an lp17 core which runs Midibox_NG and outputs the Midinotes to an PC Over USB.

 

My Problem is when i move 2 or more faders the output monitored on the pc inst correct... it loses Steps. Fader (Physicaly) is at 100% but the outputted value is anywhere between 0-127 how can that be?

 

Any Sugestions are welcome.

 

Best regards Alexander
