BCF2000 encoders and fader issue

BCF2000 encoders and fader issue

2015-12-10 by albertojriosbazan@...

Hi there,


I've just purchased a second hand BCF2000 and some things appear not to be ok:


- The fader #1. When you turn on the BCF2000, all the faders go down except this number 1. It sends midi data with no problem, but it doesn't respond to 'remote changes'. For example, in Ableton I map this fader to a channel volume. It works ok. Then I record an atumation. Ok. But when I play the track with the automation recorded the fader doesn't move at all. Beside that, when I change preset to #2 in BCF, the fader moves correctly to its recorded position along with the new preset...


The other problem:

- Top encoders #2,3,4,5,7 and 8 doesn't respond linearly when tweaking. I mean: when you tweak up and down, values doesn't go up and down following the tweak movement. Instesd of this, they shows a value and moves around this value very slowly. For example, you tweak a knob from 0 to 30. It shows 0,1,2,3,2,3,4,3,4,3,4,5,4,5,6,5,6,7,6,7,8 and so on. Its completely annoying.


What I've done:

- With BCManager I've seend that top encoders are configured with absolute parameters and cc values. Nothing strange.

- I've resent firmware 1.10 to the unit.

- I've disassembled the unit. When I get to the encoders I see them hooked to the electronic tablet inside a cylinder and I think the problem could be inside that cylinder but I wasn"t able to open it (feel like I'm going to break it)

- I have tried with different wires also.


I own a BCR2000 working like a charm and I'm used to work with music equipment of this type.

Please help!


Sorry for my syntax. Writing from a tablet.

The fader #1 problem is possibly that the 'default' setting is not 0 .

The encoders can have a different resolution for very slow, slow, medium and fast turning.
The encoders have a resolution of 96 and if set to 96 then you will get all the midi values.
If you set it to, say, twice 96 (192) you will only get every other value and other resolution values give what appears to be odd sequences.

eg

$encoder 1
.easypar CC 01 07 0 127 absolute
.resolution 48 96 144 192
.default 0

All the best
Royce

Thank you Royce for answering so fast!

Can I configure these settings within BCManager or through the BCF2000 itself?

... and if above won't solve the encoder';s issues, it might be hardware failure - you'd need to replace them.
If you need infos about the correct part numbers, just ask... I did my BCR2000...

Thank you Flavio.
My BCF2000 unit is being analyzed by a technician right now. He will tell me later what's going on and if it has a solution.
If not I will try the above software solution.
If it's a hardware problem I will ask you about what you did with yours.

For better understanding my problem, I've uploaded a video to youtube.
It it you can see that the firat knob works ok, but not the others. Althought 2,3,4... appear to be working properly you can see that there's no linear concordance.
Within the last knob it can be noticed clearly.

It looks very much like the encoders have been programmed not how you want them.

I would use an editor as it is much easier to see what is going on and yes Mark's editor will sort it out

On his editor select the first preset.
For the fader click the fader button on the preset page and look at the 'default' column.
For the encoders click the encoder button on the preset page and click on the 'resolution' for the particular encoder.


All the best

Royce, thank you for your support.
I've fixed the fader problem. Actually it was a configuration problem. It was as 'pickup'. Changed into 'motor' and the problem dissapeared.

However, rotaries' problem is still there. I've noticed that if I push up or down a problematic encoder and then tweak it, is more or less working. Also if I tweak them veeeeery very slowly they also work in a normal way. But when turning in an 'accelerated mode' it does not work. Resolution in these rotaries was configured to 96.

The technician told me the machine was not usable but, as I was afraid, he didn't know too much the BCF2000.

Now I will configure it as a mackie control xt script within ableton and see how it behaves.

Any ideas about rotaries?
Btw, I'm not able to disassemble the rotaries completely. Any advice about how to do it clearly?
Thank you all, really!

Hi Alberto,
the rotaries should be mounted exactly the same way as they are in the BCR2000. They're (of course) soldered and somehow "enclosed" in the plastic cylinders you mentioned earlier. Those are closed on the top with the ring covering the LEDs - right?
It's quite easy to remove the plastic cylinder and ring, you just have to be careful not to break the (two) plastic rods which hold the ring.
After this, you could desolder the rotary encoder. As I don';t own any BCF - are those push-encoders or rotary only? I mean, do they also have a push function, besides the rotation?
Let me know, then I can tell you what parts you will need to order and where as well (I won't earn a cent - I'm just helping out).

OK?

BR,
Flavio.

Hey Flavio!
Just, thanx!!

So I have to push the rods to remove the top ring piece?
I've not tried deeply to remove it. Feels like I'm going to break it...

If I don't find a solution I'll try what you told me and contact you for pieces.

Thank you very very much Flavio!

Hi Alberto,
no problem! Glad if I can help...
Simply be careful with the rods, but I managed to remove 2 cylinders for 2 encoders without breaking them :-) Just look carefully at how they hold together and move them accordingly...
