Sustain pedal pitch variation with Alesis qs8.2

Sure sounds like a dead battery and unfortunately yours is soldered in. To replace, you have to pull the motherboard and get your soldering iron & braid out. This may be related to your tuning issues, if some parameter is getting corrupted when you turn off power and the battery, being dead, doesn't maintain settings. This is just a guess though. Batteries are not that expensive, and the job is not that hard if you've done any electronics tinkering. Lots of folks solder a battery holder instead, then battery replacements are easy.

 

Found one.

And then there were other pitch settings apart from the LFO... And one of them was "detune". And yeah this is on for all the settings. (I change them now when I turn the keyboard on until I get the battery sorted)

I'm curious tho...

Why. On earth. Would detune even be a thing. And why would it be automatically turned on.

It sounds indeed like an LFO effect. To me it is more pronounced in the last chord played in that recording. I wonder if it is the original sound that when looped for sustain has a variation in harmonic contents that becomes noticeable? You said it happens with all sounds. Is there a pure sound (sinewave or similar) available?

On a piano?  Think upright/honky tonk.

 

It should not default to on though…did someone else have that unit before you?  If so, did you try resetting the unit to factory specs?

Yeah it's definitely previously owned. 

It's strange tho because as I had mentioned it isn't saving new settings due perhaps to a dead battery yet these weird settings are still on it.

 

I've tried to factory reset it many times by pressing 0 and 3 while turning it on but this doesn't seem to accomplish anything. I don't think it's even resetting  when I do it.

Presumably with a dead battery it defaults to factory defaults every time it's power-cycled?

 

Worth doing the battery repair though (if you know what you're doing, or can find someone who does).

 

Cheers, Mike.

Before I have the thing opened up, I'm curious if this model has a write protection option for the onboard memory. The manual doesn't mention it from what I can tell and a Google search only tells me the expandable memory cards have it.

The Presets (banks 1, 2, 3) cannot be overwritten, nor can the GM bank.  

 

The User bank should be able to be overwritten.  RAM cards just add more User banks.

  • 3 weeks later...

So I thought I'd stop in and report...

Recently changed out the battery... So yeah that was definitely the problem. That, coupled with the disabled pitch/mod wheel, along with being able to save settings and what not, all issues seem to be taken care of. I've got one particular piano sound that is sweet as can be with zero pitch LFO or any bullsh*t like that.

 

Anyway wanted to stop in and at least say thank you to all you folks who put their two cents in to help a total random stranger. Cheers.

 

PS: I still think it's weird this model doesn't include any straight piano samples without pitch detune, LFO, etc without messing with settings but eh... That's neither here nor there at this point. Thing sounds great.

Glad that worked out for you!  Did you just solder in a new battery or install a battery holder?
