Thanks for the infos !
When John Bowen has been aware of my issues, he talked with Ralf who said the motherboard should be changed. Then, finally, JB told me to wait, check for a certain Jim answer in the Forum. I presume Jim is you and the forum is that one ?
JB told me also to wait for the next os which should be released soon. But the synth has really strange behavior ! For instance, right now, I turned it on 5 mn ago without touching it and it's completly freezed ! No button can change anything and it doesn't output any midi. I'd love to know if same strange things happen for other users cause with my unit, it would be suicide to play it in live !
I'm going to try to list all weird things that happend.
Changing preset and no more sound during one mn or sometimes, never and needed to reboot.
Sometimes, after touching some parameters, it stops sounding and I can see parameters changing by themself on oscillators display ! ---> Reboot.
Also, on some preset with arpegiator, when I pressed 2 key, it sounded normally and then a third key pessed and it was like all arpegiattor notes were sundendly tied and played legato, then playing normally when pressing again keys.
For the system settings save function, I understand correctly how to do, now ! I must first turn the corresponding knob in order to display « Save on » ! Culpa mia ! It works correctly !
(And I'm a bit shamed since I did that correctly the day I received and installed it !
For the SampImg parameter which doesn't exist anymore, replaced by SmpPool in home page 3, it's ok too and apparently, fully working.
Right now again, I rebooted it, checked the system saving and SmpPool features and when I wanted to listen and press keys, no sound and oscillators + mixer displays changing there settings alone, like it is blinking every 500ms : oscillators 1 shape 13% to 6% and fine tuning 0 → +5 ! And mixer 1 input 3 displaying alternativelly Osc 3 → W noise, as I mentioned before. So I reboot it for the third time today without getting any sound yet ! This time, I changed the preset just when it finished to boot and I hear something !
And for the vocal filter, indeed, all the 5 vowels are on « A » ! I didn't saw that page ! So, it is ok too !
Thanks a lot for the answers to all my questions ! Really useful and perfect. And that reassures me a lot !
I think I'll follow JB advices and wait for the next os version, even if I begin to be sure the synth has some problems. I'll certainly come back here when I'll have more answer need !
