Greetings! In 2019 i ve purchased the Magix Video Editor Premium Pro and i ve been given the Magix Music Maker as a bonus software, for free, without serial number, or registration codes. Today, may the 9th, 2021 i ve decided to purchase the Upright Bass and the Jazz Drum VST instruments as addition to the already existing Grand Piano, Pop Drum kit and some buzzing thing, i ve no use for. Purchase was succesfull, although in order to make it happen, I had to upgrade the free software. After the upgrade, the purchase was complete and downloading, installing was also succesfull, but i still can t use them. Recording mode with VST s is possible only in ASIO drive mode, but there s no sound, while tapping the keys. It records, the monitoring led is flashing, so there s signal, but there s no sound. Plus I can listen to the tapped recording only in Wave drive mode, when I play it back, which makes no sense to me, as the ASIO recording is midi format, not wave format. I ve checked all sound settings, drivers on my PC, using windows 10, but the problem remains. Should I reinstall Magix Music Maker? Or should I purchase a higher level version of it? How can I get a serial number for something, that was given to me 2 years ago, by the company itself? What would, or could anyone suggest to do? Cheers
