IT is always easy to make people feel bad about or stupid about a certain concern that they have where the only engagement should be a solution not a lecture. If you can’t help you can skip that topic. One reason for not using the HID mode can be a missing cable… Another reason as bonus is shortage of USB port on Macbooks (2 ports only = extHDD + Sound Card) no USB hub available. We don’t discriminate a Dj who only show up with laptop and sound card because we got a standalone rider.
For this topic my proposal is to always keep SD Card with a playlist that contain Serato /Rekordbox/Traktor time code file.
Please let’s not engage a debate about standalone (SC5000/M) vs Laptop (Serato/Rekordbox/others) that’s another TOPIC.
