MT song playback ok, playlist not ok

Glad to hear you sorted it out Steve! Hope you enjoy the unit and sorry for not responding sooner.

The latest firmware release: 83859

The mac updater crashed on os x yosemite?

Do you remember what was the error message?

Many thanks for your prompt response.

Hello,

I have the same problem here. I can play the songs from folder but I can’t get the playlist working!
I didn’t know what I was doing wrong. I’ve bought the second unit recently so I could work with it at home (while the first one is built in our band’s gear).
But still no luck at all. After I press PLAY (or footswitch), the hourglass symbol appears for a milisecond and nothing happens.
Now I’m pretty sure that it has to be the firmware issue as Steven has found out.
So I am going to try to upgrade FW (I have 84xx) and see if it’s working. I’ll let you know.
Pete.

EVERYTHING IS WORKING NOW!

I’m taking back all my previous screams of pain 😉 But I’ve finally managed to get my LP-16 work again!

So this is probably my last message. I decided not to delete/edit the previous messages even when I got everything sorted out, so that the other people might read it in case they might have the same problems.

So I’ve narrowed my search for a culprit to a footswitch that’s already connected before power-on! What a nightmare! :ohmy:
Once I disconnect a footswitch the endless loop “USB reading- USB test passed – MT screen” suddenly stops.
Whenever I start LP-16 with a footswitch connected the whole situation repeats again :ohmy:

And to make it even more mysterious – this strange behaviour is caused by Yamaha FC-5 momentary footswitch.
If I plug-in a normal guitar cable everything works fine, no loop is going on. So I measured the pedal and it’s actually “normally closed”.
I forgot about this fact a long time ago. (If I connect tip and sleeve on a connected guitar cable and power on LP-16, the same “loop” thing happens – obviously)
I tried to set the footswitch pedal mode to “normally closed” but it didn’t help with the problem 🙁
The cause for this strange behaviour is definitely shorted tip and sleeve terminals on footswitch jack / connector during unit’s power-up !

I hope you’ll be able to solve this problem and offer firmware upgrade very soon. It’s very uncomfortable to remove a footswitch before power-on.
Not that I can imagine how we’ll do it as our band’s LP-16 is built in a case with a limited acces to front connectors (as we dont need them so often and we had to save some space). Of course it’s possible to use a “normally” open footswitch and it’s gonna be OK (and we’ll have to do it this way in our case) but for the future problem free operation of LP-16 this should really be remedied.

As far as the playlist issue is concerned – in my opinion Cymatic Audio should let the users know about the playlist problem in the first place. Not only in the forum but on the main web page.
It’s only a coincidence that I’ve come across the playlist problem topic on the very same day Steven Cowley posted it (although I had been fighting it for several weeks already). I’ve been blaming myself for not knowing how to work properly with Playlist Editor… (which in fact I didn’t know at first :-)) But after trying every possible combination (right to the point where I thought that maybe the playlist and WAVs necessarily need to be exported directly to USB flash, not copied in system) I found that I was not the only one in the world to have the same problem. I wonder if Steven and I were the only two persons to complain about it since I think that the playlist functionality is the essential feature that people would be buying LP-16 for!
Then there’s the V-83859 firmware problem with the footswitch pedal that needs to be addressed and solved as soon as possible. I wonder if anybody else can replicate this behaviour.

I’m sorry for writing so many serious and sometimes contradictory messages in such a short time but believe me I’ve had a couple of very nerve-racking hours here… Going from almost 100% functional – to totally unusable – to almost 100% working LP-16 again in just a few hours is just insane 👿
(I badly need a shot of my home-made ginger liquor to release the tension 😛 )

You’re welcome.
