I'm sure I've seen an almost identical question asked somewhere else (?) fairly recently. On another forum?

The big problem with questions like this, and there are frequent questions like this, is that the question revolves around specific hardware, and only marginally about midi. I know very little about any of the hardware mentioned.

On the basis of other questions, the culprit is likely to be the midi/USB interface/cable. You don't say what it is, but I read that there are various poor quality such devices about, and you do get what you pay for.

When you play live, the keyboard generate a LOT of midi data. The more skillfull your playing, the more precise the midi data may be, but even so, there will be spurious data to cope with, stray notes, etc.

When this flood of data is processed and saved within the software of the keybd, I suspect that there is a certain amount of immed cleaning up of the data, hence, when you play the saved data, it works MUCH better. However, when you try to send immed the full flood of data from the keybd, as this gets converted from midi to USB, and then USB to midi at the other end, all through substandard devices and/or software, the risk of occasional bits of data, like Note Off, getting 'lost', increases. To the point of inevitability.

I suspect the weak link is the interface. If you cannot do midi to midi (skip the USB) then you need the highest quality of interface you can manage. Sorry to say, but the best ones are prob more expensive. You get what you pay for.

Maybe someone very familiar with the specific equipment might find a better answer for you?

Yes - in the 'Home Recording' forum a week or so ago.

I would think you're more likely to find someone there that knows the specific kit, than here.
