EA-7 problem

EA-7 problem #5354
The drum volume cuts in and out. I can slide the slider than controls the volume, and it may or may not restore the volume. There seems to be nothing in particular triggering this problem; it happens totally randomly. It might go several songs and not do it, and then BOOM the drum volume drops completely out.
I checked all cables, I initialized it , I tried it with p.a. system, different cable, and now with headphones and the problem doesn't go away.
Anyway have any advice or experience with this?
I may try to open the case on my own and see if I can find the problem.

EA-7 problem #5357
I can only think of one or two things that might be an issue...

Firstly, is anything MIDI or USB going INTO the E-A7? An iPad, your PA4X, an external master keyboard?

If not, scratch that. If you do, disconnect them all.

Secondly, are any faders or controllers (D-Beam, expression pedals, etc.) assigned to drum volume?

Is it only in style mode, or does it do it to SMF's too?

That's what I'd check first... Is the mixer active when you do this, or is there a slider for ACC1/ADRUM active? Try moving the ACC1/ADRUM slider while in mixer mode and see if the values 'jump' around or it's a smooth movement.Next check the ACC1 button, see if there's any stickiness to it, or any unreliable operation.

Oh, and, is there a 'Track Mute' button, which if set to ACC1/ADRUM and has an issue, might be your problem.

If the drums are going down the same cables as the rest of the mix, you can be assured it's nothing to do with those.

If under warranty, I'd see about a replacement fader set or buttons if it turns out to be the issue. You can try some Fader cleaner like DeOxit F5 (not general cleaner) and see if that works (it helps with my BK-9 faders).

Even if not, I'd go ahead and order replacement parts, because Roland are not keeping production of spares up for very long these days. A replacement set of faders for my BK9 is no longer available.

Hope this helps.

Thanks Diki,
Nothing connected. I did a factory reset and it still did the same thing. I then reloaded the operating system. Same thing.
I will get some of the fader cleaner and try that.
Fortunately I have my "old" Korg PA4X, so I won't have any downtime as far as working. Just another reason for having backup for EVERYTHING. :)
I called the service center I use I Dallas. They will let me come by appointment, drop it off and pick it up the same day, if they don't have to order parts. Maybe I should go ahead and order the replacement faders.
Too tired to worry about it until the week is over.

Usually, if it's a fader, if there is a display of the fader values, you can see that jumping around a bit as you move the fader.

One thing to check carefully is, are you transporting the arranger in a case that allow the arranger to flop around inside the case a bit? I always worry about elements that stick up a bit (the bend lever, any faders etc.) getting contact from the lid or its padding.

It is quite likely the faders can't be ordered individually (that was the case with my BK-9) and you'll need the whole board with the set. Hopefully it's either under warranty or not too expensive...

Well, I have been able to isolate the problem to the slider. I turned off all the style parts, including drums, then switched to the ACC1 screen (controlled by the same slider). The problem still exists with the ACC1 volume, going in and out on its own. When in that mode, the drum volume stays constant where I set it.
I am able to wiggle it back and forth and push it down and it does better. Still need to get the fader cleaner and see if that helps.
I can adjust the drum volume, then switch screens and even if the ACC1 volumes goes off and on the drum volume is not affected.
So if I must use it before I get it repaired (no reason I should need to) it would be more usable that way.
Hoping cleaning it will help.
Maybe I shouldn't have let my cat pee on it.
JUST JOKING. :)

EA-7 problem #5379
Well, I have an old friend that owns a tv repair shop. I took it to him and waited while his technician checked it out.
The problem wasn't cleaning though. He took it all apart and had to resolder a contact. It works like new!
They didn't even charge me, but I gave them a gift certificate for dinner where I work.

Glad to hear the solution was simple.

I'm not kidding about those spares if you feel you'll hang on to your Roland for any length of time, though. I was shocked and dismayed to hear how some critical components are simply not available for the BK-9 after only 3 years or so past the end of production, particularly parts related to high stress components like buttons and sliders.

Roland's new arranger cycle has ground to an almost standstill, so the prospect of actually HAVING to hold on to your arranger whether you want to or not has risen dramatically. This means that some of us are going to be using our Roland's for a LOT longer than we used to compared to the days when new models were about four or five years apart (or sooner!).

Hopefully, the problem with the BK-9 is due to it being the last model built in Italy, and component changes to the Chinese production facilities. Currently, we don't really know... But it might be prudent if you, like me, anticipate using your Roland for many years to come think about possibly ordering replacement parts for some of the high stress components that are cheap (faders, buttons like Start/Stop, etc.) just in case...

The good news is, the one component that I find doesn't last very long (I am a VERY heavy user of it!) is the bend lever assembly, and that is common to all BK's and apparently some other Roland products, and they have no shortage (I'm going through my third, with my gig BK-9!). But it appears that production and availability of spares isn't as big a priority as it used to be with Roland (I am not sure what the situation with legacy Yamaha or Korg products is), so bear this in mind as your arranger ages.

No-one knows if Roland will ever re-enter the high end market again (G70 level) or even the MOTL market (E60/BK-9)... For the foreseeable future solely the E-A7 is the 'pro' level arranger Roland make. Take good care of yours and keep an eye open for possible spare part shortages..!

I was researching the fader parts. It seems the ones this one needs are the same as those used by some Yamahas, so they most likely will remain available.
Joystick is a good idea. I have had to replace two of them on two separate Korgs. Be sure to pad them when transporting!

Well I must confess to being a DA. I thought the EA7 had another problem with the sliders. I couldn't hear any of the style parts except bass and drums. I worked the sliders up and down, nothing. I was certain to see that the indicator lights were on. I didn't want to take time to reboot, right in the middle of the last set with a roomful of people, so I finished the night with drums bass and lead sounds.
I took it home and booted it up and everything was fine. Time to investigate. I knew about the Track Mute button because I use it when I play some midi files. I didn't realize that it worked on style parts too, and the default is "mute all the parts". I actually had that function assigned to a programmable button. The error, once again, was with the user.
Love the EA7 by the way!
P.S. Spent an hour or so moving UPGs into alphabetical order. I only have about 70 so far. From now on I'll move the new ones to the proper place each night! It wasn't a hard process, but I'm glad I did it now rather than wait until I had a couple of hundred.

Track Mute is a pretty powerful feature, it's one of the first lights I check if I have used it that session!

I checked the E-A7 manual, Don, I didn't see any reference to having different assignments for style and SMF play. Is there something the manual missed? The BK-9 has a different set of mutes for style and SMF play (which makes sense) but I couldn't find a reference to this in either of the E-A7 manuals. There's a p.2 tab, but the manual says nothing about what it does.

I think the E-A7 missed out on one really useful thing on the BK-9. The D-Beam can be assigned to muting a variety of other style Part combinations, ADRM, ABASS, ACC, and all the combinations of two of those. So, with a combination of Track Mute set to ACC (which just leaves the bass and drums going) and the D-Beam set to ABASS (for instance) you can choose to drop to bass and drums, or drums only, or drums and ACC (by using both), and do a sort of DJ remix on your styles. Donny... give these a try if you are using styles much these days. It's a great way to stretch more variety out of a style!

It's a shame that the 7 Assign SW's on the E-A7 don't offer this. It's a great feature. One thing the Assign SW's did get right on the E-A7 is that they are per-Performance, not global (like the BK-9's D-Beam, FC-7 and Track Mute). If you think about it, the 7 As.SW's are really just re-tasked FC-7 inputs (that there are seven is pretty much the giveaway!) but for once, Roland thought more carefully about them, and decided a single global setting wouldn't work, as many choices as they have... It's a real shame Roland didn't think that way about the FC-7 on the BK-9. You really need utterly different assignments for style play and SMF/MP3 play, and having to settle for one is quite limiting!
