This has (and should have) nothing to do with my SD card speeds. Even my SD card with 50Mb/90Mb is like throwing pearls before swine, heck it’s actually more meant for serious tasks like 4k60 recording rather than being required for music files which have a FAR lower bandwidth demand. Afaik the USB-readers on all Denon and Akai devices (except the blue ones) are ‘only’ USB-2 bus speed which equals to 480Mbit ≈ 30Mb/s in real life. Oh, and Class U1 SD cards only have to reach a minimum of 10Mb/s writing speeds. Pretty much any SD cards nowadays is at least U3. No, I don’t use cloud services at the moment. If I do, then never more than one at a time. * * * - The LED issue even occurred with no media inserted at all (just the demo tracks). It’s a boot routine error for me: Sometimes it glitches out and then only the Engine GUI loads. - The overview waveform bug is inconsistent, only 5-7% of all tracks in my last sets were affected, and the rendering animation of the main waveforms remained flawless. So it’s not a buffering issue either, more like a routine/check failure, similar to the LEDs. - The (rare!) jog wheel failure seemed to be an isolated event which ‘self-healed’ during my set. No idea about that. I have Vinyl Mode deactivated most of the time. Potential grounding issues only affect the capacitive surface, not the pitchbend mechanics, which also didn’t work. But pitchbend with -/+ buttons is a workaround, so no biggie. - The long tracks = freeze issue only happens when using the track skip buttons, but _not_ with the navigation encoder. A clear software issue, but again no biggie, just weird. Hopefully the next x.1 or x.2 updates gonna kill those small hiccups. --- _[View the full topic](https://community.enginedj.com/t/sc-live-4-overworking/45772)._
