Hi. Can anyone refresh the link from OS to Mediastation X-76?

Please refresh link

Dear Nigel!
If you still have the ISO file for the Groove X-7, I would like to ask you to share it with me, unfortunately I can't download it anywhere to get my instrument working again.

Try right click the link in the first post and choose 'save as' and point it to tha location you want to store the iso file.

Hi!
- Yes, I tried, but unfortunately the file is no longer available on the website.
(I get this error message when I want to download it.)

I hope that Google Translate will translate well, because I only speak the language very poorly...

Yes, you're right.
Seems like the file is no longer there.
It's quite an old post, but maybe admin have it on the SZ server still?

Btw, your translation by Google works well. 👍

- I would be happy if it were available

I started writing a program for it in VbNET in a pinch,
because I would like it to work, but many functions still don't work.
I can only use the keyboard and the control buttons together with the potentiometers. Decoding the buttons went relatively smoothly, but the potentiometers gave up the lesson, but I managed.
The states of the individual potentiometers are multiplexed, and all control messages are in the form "F0........... crc CC".
(CRC = 1 byte checksum value) The messages had to be converted to VSTs.

The sound is now on the motherboard sound card using ASIO4ALL.
It would be possible to add a USB or other sound card, but it would be too early at the moment, because
I haven't given up hope of being able to restore the original OS.

Unfortunately the LED lighting of the buttons doesn't work because I didn't figure out how many commands the panel expects.
