Quite a few times when I have been playing the Fusion, I have experienced a sudden drop in volume, with the sound becoming very muffled as if a lowpass filter has been applied to t he sound.
I vaguely remember seeing a post describing a similar problem on the old board, but have not been able to locate it.
Has anyone else experienced this ?
By the way my OS is 1.24.
Thanks and best regards,
Valiant

Quite a few times when I have been playing the Fusion, I have experienced a sudden drop in volume, with the sound becoming very muffled as if a lowpass filter has been applied to t he sound. Is this permanent or such temporary and intermitent (i.e. lasts a second and then reverts)? Are you maybe 'catching' the filter's front panel knob when using the mod wheel? And how 'vigorously' are you playing? If you're really whacking the thing, I'm wondering if this is causing something assigned to cutoff to slip through vibration. I dunno basically (and can't say I've heard of this particular one).

Thanks for your quick response ! I'll spend a bit more time on this to see if I can more clues as to what is causing this. Thanks again. Regards,

Silly question... do you have your Fusion's master volume knob turned right up full? If so, does the problem recur when you turn it down to about 50%? The Fusion's output is a LOT hotter than most other keyboards - mine stays at 25% most of the time; what occurred to me was that it might be overloading something down the chain... just a wild guess though.

I get a drop in volume when I use the Fusion to play along with a Sonar backing track. As soon as I start the sequence, the volume drops, when I stop the sequence, the volume returns to normal. (There are no midi messages for volume in the sequence from Sonar).

Some sequencers send out safety 'reset' commands when you start playback - I wonder if Sonar is sending out something Fusion doesn't like. There may be Sonar users here who might be able to help.

Steve Thanks Steve, but my point about Sonar was only an observation and the volume drop is not really a problem for me, as I know it's going to happen and I can allow for it. I didn't mean to hijack the thread! Valiant's original problem seems different and more serious, especially if it happens in the middle of playing a piece on the Fusion, and he's probably still waiting for a solution. Paul

This doesn't sound like a common issue to me. It would be worthwhile to check out whether the volume drop occurs in the headphones as well. If not, it could be a bad connection (assuming that analog out is used). Else, hmm... are the CC# settings standard, or are they perhaps mapped to something that conflicts with filterfreq? Just an idea.
Edit -- which reminds me. By default two of the four performance knobs have CC#s that correspond to effect send levels. I think they were 91 and 93. In the past I've had problems with effect send levels interfering with performance controllers in mix mode, so I've mapped these controllers to something else, on the global -> MIDI page. Perhaps you experience something similar?

Thanks for all the replies to my original post !
Looking back, as far as I remember, I have only experienced this problem when I had the Fusion connected to my midi-patchbay, so I don't think this is a problem with the Fusion. Somehow, when connected to the midi-patchbay, it seems the Fusion are receiving midi-messages relating to filter settings.
So, I don't think there is any reason to spend any more time on this.
Thanks again for your support !
Best regards,

Whatever it is, I hope you get it sorted - little problems like this can be really irritating to track down. Good luck and let us know if and how you fixed it - could prove valuable for others.

It seems I spoke to soon with last post, believing that my problem was caused by midi messages via my patch bay.
I experienced repeatedly today that the Fusion filter setting would change. Each time I would have to go to reset the filter frequency setting with knob 1 in the matrix to change back the muffled sound to the original sound.
I will contact Alesis support about this and another related problem with the keybed - please see separate post in General setting for this.

Further to my last post:
This problem with the sudden filter change happened to me this time when I was playing the Holy Grail Piano patch.
I copied the patch, deleted all modulations, including effect modulations. I disconnected all midi pedals. I disconnected all external midi, and yet I still experienced sudden filter setting changes.
Not that I don't realise that the members on this board have plenty of other things to do, but if anyone have any further clues as to what is going on, your input would be greatly appreciated.
Thanks and best regards,

Hmm. Possibly... If it happens again, try turning your filter knobs up, and then back down to 0, in turn. Does that solve the problem? If not, try rebooting your Fusion. Does that make it go away? The reason I say that is that I've noticed a slightly different bug, where if I go to the filter control knob and set one of them to non-0, then sometimes when I change patch the next one I play ends up with the filter pretty much fully closed for the first couple of octaves (that's the really bizarre bit... above middle C it's fine, but below everything's a bit nuts). Now in every case so far, I've been able to fix this by turning the filter knob up and then back to 0 (I think it happened 3 times with the cutoff knob and once with the keytracking). Having said which, the Fusion started doing some other strange things (not letting me select certain samples, etc) so at that point I rebooted it and everything else went back to normal... and that's not the first time I've observed my Fusion behaving in a strange way, but been unable to replicate it the next time I turned it on. One of the Fusion's quirks does seem to be that it needs a periodic reboot... but hey, it's nowhere near as bad as Windows 95 was! But I'd guess that if you're the kind of person to turn it on in the morning, play with it all day, and turn it back off at night - chances are that despite being a heavy user, you'll never see some of the odder bugs that have been reported...

Thanks for your comments, gwenhwyfaer. Not that I'm happy that you have experienced similar quirks, but at least I'm not the only one who see my Fusion behave strangely at times.
You, at least seem to have pretty good troubleshooting skills when it comes to the Fusion, whereas I most times don't have the slightest clue when it behaves differently from my expectations.
I just hope that these quirks or bugs or whatever they are won't happen to me during a live performance. I take your point about Windows 95. I guess that at some point one may have to trade features and complexity for lack of features (simplicity) and reliability.
Perhaps, it's naive, but I'm still hopeful that the Fusion one day will be free of quirks or bugs.
Regards,
