Flam with simultaneous pad hits

[dmitri]

Sorry, I've been busy lately with building modules and I'm away at the moment till 25th. I'll certainly do more test and, if there is a problem in MegaDrum, I'll fix it, but the issue looks very specific and very narrow so it may take some time.

OK, there's no hurry, I could live with that for six months

Just post in this topic if you can or cannot reproduce the problem when you'll have some time.

I can also send you my device if there's a need for that.

Can you please test this firmware:

To simplify testing/comparison you can use Latency settings to choose standard/modified MIDI processing.
With Latency set to an even number it uses standard MIDI processing.
With Latency set to an odd number it uses modified MIDI processing.

With latency set to 11 for modified MIDI processing I am happy with the result of my audio test, with 2 and 3 inputs as well (note-off messages removed as usual). The interval between notes is increasing with around 1ms resolution. Thank you very much.

I am only surprised nobody else reported it, since this issue was easily audible for me.

Here are my thoughts after a few days of actually playing drum kit with this firmware.

Sometimes (I believe it happens when i hit tom and kick pads in a perfect sync, but I neede some more testing to find it out) one of the two hits is completely or partly canceled. By "partly" I mean that I hit the pad very hard and get only a fraction of expected velocity.

I does sound like a XTalk suppression. Are Tom and Kick in different XTalk groups?
