Bug: once a sound is loaded, it is unchangable.

[brumd]

Hello everyone,

after I got all the parts I needed, I recently built my Preen FM2! It works, and I am very happy with it. Incredibly great and versatile synth for ~€100 (I still had some parts lying around) (I am so glad I didn't go for the Volca FM.. This is so much more). It is running: it came with Firmware 2.08 pre-installed, and I added the soundbanks.

But, this I can't figure out:
I can pre-listen to presets, but once I have loaded the sound, I cannot find an option to load a new sound. It sticks with it forever. I can edit it, but I cannot load a new preset. Interestingly, when I browse through a bank, I can hear the sound when I press button 1-5, but when I play my MIDI keyboard, it will play the loaded sound. After I hit 'loading', nothing is updated.

I have updated to firmware to the newest v2.21, but this behaviour stays exactly the same.

Maybe I am doing something incredible stupid, and this is easily solved. I would think it is quite unlikely that is caused by a hardware error, but why would I be the only one that reports this behaviour?

I would be very happy if someone would help me out here.. thanks very much in advance!

This sounds like you are pressing the wrong button and instead of loading the new sound you cancel the operation.

No. I am pressing the exact same button (7) as I do the first time. Remember, it does load a sound. But it only does it once.

Well i don't know exactly what you do, but it seems like a strange bug, since many people would have noticed it by now...

Can you load any sound as a first sound? Or only one?

Are you loading your new sound into another instrument maybe? (Which would listen to a different midi channel and hence never receive midi from your keyboard)

Exactly like this:
*before* I load a sound, I can preview presets, and play them with a MIDI keyboard while browsing them.
But when I decide on loading one preset. I can no longer repeat this.

*after* I have loaded a preset, I can:
>still here other presets when played with button 1-5 on the Preen.
 >not here those presets when played with a MIDI keyboard
>pressing button 7 still shows the 'loading' screen, but it does not load the sound. It will play the preset that I loaded first. No change possible until I re-power the Preen.

Yes, it's very weird. :/

ok, apparently the problem is solved (?).

Even weirder: I kept testing what exact behaviour caused this problem: was it when loading from a specific bank, or only from the DX7 banks? And then.. at one time it stopped doing it. I've tested it about 10 times, and every time it kept working. But I haven't really done anything. So, I don't know if the problem will come back. It's a true mystery.

I am sorry to bother you all with this. I go and start exploring this great little machine!! I reaaaallly like it! Thank you Xavier for creating it.

(@Lokki: I guess the only thing that would make some sense it indeed loaded new sounds as a new instrument, using a different MIDI channel. I have opened those settings, and maybe accidentally I made changes there. Thanks anyway for your input!)

I am glad it works for you now!
