Hi guys,
I´ve received the encoders from Mouser.com and they are finally the right ones:
Top is original, bottom is Bourns PEC12R-4030F-S0024
That is the same type, not rasterized, 24 ppr, with push function.I have already tried them in the BCR and they work great. The physical resistance is a little lower in the Bourns (it´s easier to rotate), which in my opinion is great and feels like higher quality actually. The encoders in my old BCR from 2004 feel the same way.
I have ordered quite a few of those and will sell them for 3 Euro per piece+shipping. I´m thinking of ways to incorporate it into the store, in the meantime just PM me if you´re interested or write to support@zaqaudio.com
Cheers!
Have you already tried adding a bit of new tin? I know it´s counterintuitive, because I was so happy about every it of tin I was able to remove, but in the end it really helped. The new one goes off again very easily and takes away the old tin with it.
Hi guys,
on another note, I finally just bit the bullet and ordered some of the (hopefully) right encoders from Mouser.com. High quality replacements from Bourns with a push function. If they are really the right ones I will let you know. I´m thinking about offering them through here anyway, as the 20 Euro shipping costs from Mouser are quite steep for small quantities.Hi Flavio,
yes, I would recommend setting the iron to 450°. At lease it´s how I learned to do it at my apprenticeship as a TV technician back in the day.
In my experience it´s only critical if you apply this heat (longer) to semiconductors, but not to mechanical elements like the rotaries.
I´m not an expert on this anymore though, so if you´re unsure I recommend reading around at the different forums, there is lots of advice there…I always desolder with 450° and did not have any problems with it so far, that much I can say.
I on the other hand only worked with soldering wick the last 15 years, but with the encoders I could only succeed with the pump. Here´s another tip: try adding a little bit of new soldering tin to the pin, it will refresh the existing tin, making it easier to get it in a fluid state and removed.
Hi guys,
thanks for the updates.
Yes the desoldering is not easy. I recently managed to do it with a desoldering pump:

Still it was not easy, but eventually manageable…Hi Raphael,
thanks for your feedback!What Zaquencer version are you on?
The behaviour you described should actually have been fixed in version 1.02.From the changelog:
Bug Fixes:
- when copying a track in load menu, would always copy track of page 1 instead of selected pageCheers,
ChristianHi guys,
thanks for the suggestion!
I´ve just played around with the little Flash software from the link and it´s really fun.To be honest though, I don´t see a way that this can be realized with the Zaquencer´s parameters and I think it is out of the scope of the current firmware.
The biggest thing is that the number of steps that the individual drum instrument plays versus the other drum instruments can´t be adjusted. Sequence length is a per track parameter and that´s the place where the limited flash memory comes into play. I can´t make it a per-instrument parameter because of that. Also I´m not sure how it could be crammed into the existing user interface.I could imagine that it would make a nice separate project. I´ll think about how the BCRs UI could support that. But don´t hold your breath, there is already so much to do atm.
Wow, this is a great price! Please let us know how many you have to order…
Hi Martin,
happy to hear that you can make use of all the 192 slots
Yes, SysEx transfer is only possible as of 1.03.
It should not overwrite any patterns at all when you perform the update.Personally, I would record the output as midi on the computer beforehand, just to make sure I at least have the midi data if something goes wrong. Maybe you can set up a pattern chain from 1 to 192 and just let it run, while recording the output.
I don´t think anything can go wrong when updating the firmware, but if 192 patterns are at stake I would be doubly careful.
Hi udbhav,
thanks for your question!There is no way to automatically copy a step right now.
Feature request is noted.Maybe you could cut 5mm pieces from the old shafts and insert them first inside the knob caps, then put on the caps?
Great idea!
I did just that and it works perfectly!
It took a little time to find the right length, but now it fits great.
I had to cut the shaft to 9mm (startet with 5mm, then added chips +2mm, +2mm) until it finally fit like the originals.The discrepancy comes, because I don´t think that the original encoder stops the cap with it´s top, but with the little step on the bottom of the shaft.
But with this method you can make the Bourns PEC12R-4025F-S0024 work.
Hi Citric,
the encoder that should work is the Bourns PEC12R-4030F-S0024.
I have tried one from the same series, but with a 25mm shaft instead of 30mm like the one above has. The shaft of my encoder was 5mm too short, so the one above should really work.
Electrically it worked great and it cost around 1 Euro.
Of course if you wait for Flavio, you most likely will be able to get the information about the original replacement encoder. It is a bit more expensive, but then you know you have the exact one.There is only the page in the manual that outlines the general SysEx structure so far.
I would be willing to share the parameter layout in the SysEx messages if anyone want´s to work with it, say to expand the open source preset manager.
Bear in mind though that the SysEx is not suited for realtime control (like with some synths), as the message is just too big and it takes too long to transmit.
One of the next big feature requests is the remote controllability and I´m aware of that.Cheers!
Hi Roni,
just to make sure, the test with the Edit button refers to the original BCR firmware from Behringer. It wasn´t clear to me from your description above.That´s right, what I forgot when I wrote about the presets is that the Zaquencer demo does not overwrite any presets. So if you reflash the Behringer firmware to test, all the original presets should still be there.
You can find out the mode that the Zaquencer is in by looking at what LED is on. Either it´s one on the right if it went into Mixer or Inst Select or Store/Load/Global mode, or if all these are off, you can see the mode from the LED that´s lit in the two top rows.
I have not heard about another component causing this behaviour, only the display. This doesn´t mean that it´s impossible though. I have personally fixed one device following the repair instruction, but I´ve also heard of users that were not successful with it. The problem is that there is not so much experience here, because the number of devices with this bug seem to be somewhere in the 0.5% range.
It´s important to do the multimeter test before exchanging the display. Can it be that you didn´t see the faulty segment, because maybe the software did not use all of them? Especially the first of all four digits is not used too much. Then there is also the dot “.” in each digit which is a seperate segment…
Hi Roni,
the way it sounds from your first post definitely hints to the multiplexer hardware bug described in here:
http://ricardo-dias.com/2013/07/19/repairing-a-behringer-bcf2000/
The classic sign being that one button triggers multiple functions (from other buttons).The strange thing is that it doesn´t seem to happen with the original firmware. Have you installed or programmed some controller presets after uploading the original BCR firmware?
In the hardware issues forum post on here I recommend testing the buttons like this:
- enter the edit mode for every button (hold edit + press button)Ususally in the original firmware they show the funky behaviour when pressing multiple buttons at once. A device with tha hardware error that I´ve tested here did not go into edit mode for the affected buttons.
I can only advise you to test it some more and if the suspicion solidifies, follow the repair instructions from the link I´ve posted above.
