I have recently acquired a Reveal MusicStar music keyboard to use as an input device for Dorico, my music composition software. However, the keyboard uses an MPU-401 plug which needs to be connected to a sound card. While a sound card was included with the keyboard, it requires an old-fashioned PCI slot, which my MSI Pro Z-790-P WiFi DDR4 motherboard does not have. It does, however, have a PCI-E x1 slot, which is what I plan on using. Is there a current sound card that would work with this slot, or should I try to find a PCI-to-PCI-E adapter instead? Thanks in advance for any help and advice!
