"Finally opened up the Blofeld and had a look around, then decided I felt up to desoldering one of the encoders for a better chance at identifying it (with the intention of upgrading all of them in the near future)."

Software is usually optimized for encoders. The user might end up with an encoder that only sees every other click, jitter, or other odd problems. I've had beta test units where the encoder changed and the software had to be rewritten.
ReplyDeleteHey - I took these pics to figure out what resolution encoder to replace these with. If anyone knows more about these than I do, please let me know so I can source some new ones. Basically I'd like to find more reliable encoders for my Blofeld, as I'd like her to be a little more stable and live-tweakable. Thanks!
ReplyDeleteHmmm. Maybe, but I would hope that if I found an encoder of the same specs (resolution/pulses, detents, endless rotation) it would act the same. Am I wrong to expect that? I guess this is why I'm looking for more experienced encoder replacers.
ReplyDeleteI hate these things. My Q is almost unusable becaus these damn things. All but two need to be replaced... I know there are links for the Q's encoders to be replaced but I'm not sure if these are the same.
ReplyDeleteWhy don´t you ask Waldorf-Support for the encoders they have built into the Q/MicroQ
ReplyDeleteNote some of the jumping could actually be due to dust. The encoders are supposed to be self cleaning, meaning thirty or so turns in each direction should do the job. This worked with older Waldorf gear.
ReplyDeletedust. shoot, that is the problem with my Jomox XBase 09. after reading Matrix's post, i popped off a knob, and sure enough, total dust. thanks for the tip.

ReplyDeleteOk... cancel that. I tried that about a year ago and just out of curiosity, I tried it again and it worked this time. I'll be damn! Many thankx!!
ReplyDeleteSo I think I found a replacement to try - It's made by CUI and is the ACZ series encoder with 24 detents and 24 pulses per revolution. Same basic specs as the Alps pot I removed, but with nearly 7x the expected life span (Alps: 15,000 rotational cycles, CUI: 100,000). They cost $2 from Digikey, with no minimum order. I'm going to try it out first and report back. Here's the Digikey link: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=102-1786-ND
ReplyDeleteAll right, got the new part and soldered it into place (it's the exact same size, shape and shaft length as the original, with the same pin spacing and anchor tabs). And it works! It has a little bit more positive 'click' to each detent, which gives better tactile feedback than the original and therefore makes it easier to feel each step clearly. That and it tracks perfectly in all modes. Success!
ReplyDeleteHi Sami,
DeleteI was wondering if perhaps you'd also might tell us which models at digikey are suitable to replace the other encoders as well.
Thanks a lot,
Chris
Hello Sami,
DeleteI know that this is an old topic, but I just wanted to check one thing with your fix. When you replaced the encoders with the 24 pulses version, did each pulse track 1 value or 2 values?
Thanks!
I would like to ask you same question?
Deletethanks
just to respond on the detent controller: the detents in the encoder will not fit the parameter increase on the Blofeld, best you take encoders without detent
