Thanks for your answer. But if I cannot play the internal sound with the Sylphyo Bench, is there another possibility to play the internal instruments apart from headphones, the amplifier and the "Sylphyo with PC via Audio Out" solution? With the software (Garageband, Mainstage etc) I used until now I always played software instruments, not the internal instruments of the Sylphyo. Do I overlook something? Or do I have to buy a DAW or a sequencer for this?
"First, the Link has all the sounds contained within the Sylphyo"
The Link has not really sounds in it, does it? It's the Sylphyo that has a sound generator, and the Link is routing the Midi signals to the software on PC or Mac, or am I mistaken?

Hi Maxence
Thanks for your answer.
"First, the Link has all the sounds contained within the Sylphyo, you just need to update your Link in the same way as your Sylphyo." This information is not correct, I have the latest update of the link and of the Sylphyo. What I had to update was the Sylphyo Bench. Unfortunately, the download link for the Bench is somewhere else and there no information about the software version is visible. Maybe you could mention this on the Update page and put the link for the Bench also on this page (normally that is the place where people expect it to be).
"Plugging in your Sylphyo via usb to use it as a midi controller does not actually drain the battery or ruin it." I'm glad to hear that and that is what the battery producers tell us, but I'm not yet convinced. We still have to wait for a battery producer who gives us a warranty of two years or more.
"Regarding your comment about no bluetooth functionality.." I don't criticize that the Sylphyo has no bluetooth, I agree with you. I only point out in my article that you need headphones with plugs and cables, because nowadays everyone seems to expect bluetooth headphones.

During the corona lockdown I had time to try out different configurations with my Sylphyo. I just finished an article about the different options and their advantages and disadvantages. This might help someone who is evaluating to buy a Sylphyo or who starts with it.

Yes, I use a plug. I tried several solutions but none of them was really satifying.
But then I found out, that cutting a piece from a household sponge wipe is perfect. It does not cost much, you can cut as thick or thin as you like and it's quickly replaced when spoilt through moisture.
