In fact I’m wondering if it might be the “note stealing” problem that is common on the JX-8P due to the low polyphony. The only remaining little problem is the stuck notes which really isn’t happening all that often.
#BCR 2000 CONTROLLER SLOW PATCH#
I clean up the problematic membrane tact switch and after putting it all together, I was successfully able to access the internal patch bank thank goodness! Now I can access, transfer and save patches. I thought i would check the tactile switch and to my surprise three of the wire connectors to the membrane board were practically out of their sockets. I had a problem with the internal patch select button not responding. It looked good, but the button membrane board above it looked to be tampered with which was interesting. This evening I actually opened up and removed the main CPU board of the JX-8P. I have four IC chips to possibly replace and will definitely be able to socket them. I just put in an order on Ebay for a bunch and will no doubt use them. Hello Peter! Thanks for the tip about the sockets.

Here’s a demo on Youtube of the Roland JX-8P in action from Jexus. There is a brilliant Roland JX-8P editor in Midi Designer and it works awesome. I use the Midi Designer iPad app as a PG-800 controller. After my Roland Juno 106 experiences, I really don’t want to be bogged down again with chip issues again….laugh. The good news is that it’s not a huge problem and most likely fixable with NEC D8253C-2 chips. We’ll see.Ĭurrently I have yet to get accepted to the Yahoo JX-8P groups which often has discussions about these sort of issues. I could test after each one and hope for the best and get lucky. That’s 24 pins of soldering for each chip. So far, I would say the NEC D8253C-2 chip problem is minor although I would love to find out which chip is the culprit rather than pulling all four. For the price I paid, I expected a major issue. So I’m not completely worried about it unless it gets worse. For live purposes this could be a problem if one is not paying attention.

For recording purposes, the stuck note is a non issue really. The stuck note also happens very infrequently but enough to probably happen once or maybe twice during a song. The stuck note is also mild and not “in your ear” blaring away! Hitting the note again did not make any sound rather it simply cut off the stuck note.

Am I sure this will take care of the problem? No, but it’s a start and with one success story it’s as good a solution as any at the moment.Įven with this sticky note problem, the Roland JX-8P is very playable and I found that if I could decipher the exact note right away, I could simply hit that note and it would go away. This is not a big problem, but it does mean a short soldering job is in store. I also noticed that these chips appeared to be soldered. Does the “2” and “5” make a difference? I’m not sure, but to be on the safe side I decided to order a set of NEC D8253C-2 chips off Ebay which are readily available for around $4.00 each. I opened up the Roland JX-8P and found four divider chips labeled NEC D8253C-2 and NOT NEC D8253C-5. I decided to investigate more about this. He fixed it by replacing a NEC D8253C-5 divider chip. I did find while search for similar problems a member on Gearslutz who reported the same issue.
#BCR 2000 CONTROLLER SLOW MANUAL#
I’m currently checking out the service manual ). ( Perhaps not so if some sort of diagnostic test could be run which I’m not aware of yet. I’ve pretty much ruled out the idea that this is a dirty or problematic key due to the fact that it’s all completely random. It also happens on different notes and not the same one.

One problem I did find so far with my Roland JX-8P is the occurrence of a stuck note that happens completely at random. I feel I need to do some programming a bit and scour the web for some better patches, but I know with the right ones, the Roland JX-8P is going to sound great. After testing it out and playing through the presets and internal patches it’s not all that bad of a synth. I’ve always been interested in this synth because I’ve heard it’s been used on the a lot those Italo Disco records for strings and pads. This week I found a Roland JX-8P in great cosmetic condition.
