Stuck Midi Notes
« on: February 10, 2019, 03:26:24 pm »
Hi, I've had my Keystep for just over a day now and I've been having some real trouble with midi notes sticking when using the keyboard over USB as a midi controller. Some "note off" events just seem to be going missing.

This is especially noticeable when using the sequencer or arpeggiator, but also happens when just playing the keyboard. I've recreated the issue easily in Ableton on Windows, also in Reaper, FL Studio and standalone VSTs. The issue also happens on a Linux installation using Reaper. The problem occurs when using either the internal midi clock as master or when using Ableton as master and the Keystep set as slave.

I've found some reports online of other people having this issue but not seen any fix, is it a general issue with this keyboard? It's a shame as otherwise I'm really happy with the keyboard, but if I can't find a solution I'm going to return it as it makes the keyboard pretty much unusable for me.

Any ideas please? I've attached some screenshots to show the issue, one using MidiOx clearly shows the missing note off event.

Thanks

Which firmware are you on?  I remember getting the same issue when I first bought my Keystep.  I updated the firmware and it stopped.  It's not listed as a fixed bug but I can't think of anything else that would have stopped it from happening.

Sorry I should have mentioned that, it came with the latest firmware 1.0.1.15 already installed. Thanks

Any glitches I had with keystep ended when I updated to the latest firmware and bought a better USB cable. Also are you using it through a USB hub? That can be an issue too.

Thanks for the reply, I've been using the cable that came with the Keystep direct into USB ports on my tower - I've tried several different USB ports (some USB 2, 3 and 3.1) with no change. A different cable is a good idea and was worth a shot, I've just tried some other USB cables and still have the same issue unfortunately.

Are you at all able to try it on a different computer? As always, diagnosing these problems is about removing the variables one by one.

I've finally managed to get my hands on a different computer to test and it does appear to be my computer that's the problem here ??? Not sure whether to be relieved that my Keystep is ok or gutted that it's my computer! Replacing it isn't really an option as it's a tower that I recently built with a decent budget, maybe it's a motherboard issue? I've just updated my BIOS and still got the issue, doesn't seem to be a driver issue at it's happening in Windows and Linux. Tried unplugging all other USB devices, fiddling about with BIOS config and anything else I can think of with no luck... the only thing I can think of trying now is risking a tenner on a PCI USB 2.0 card to see if that makes any difference. Failing that maybe it's an excuse to buy some more hardware ;D Thanks again for the help, if anyone has any other ideas please let me know.
