MIDI N-Tap Delay:Bug?

[kobraji]

when I use MIDI N-Tap Delay:
with values above 50 reps; 0.1 beat.
Qtractor automatically closes the project.
I do this in order to emulate the MPC Note Repeat; in the hi hats.
There is some advice?
I use many repetitions to prolong sustain.
He works fine with few repetitions.
Thank you.

Edit:
with few repetitions also closes the project.
I installed without prefix --user; only sudo make install.

I don't have recent qtractor and cannot reproduce this with Ardour4 nor jalv.
One possibility is that the midi-buffer overflows: too many events in a short time.

Can you try with jalv.gtk http://gareus.org/oss/lv2/midifilter#ntapdelay ? It would be nice to identify if this is a general issue with the plugin on your system or something specific to qtractor.

If you use jack1 (jackd --version -> 0.124.X), you can increase the midi-buffersize using the -M option. Though I don't know if that's relevant (since qtractor does not use jack midi).

PS. install location (prefix) does not matter, unless you have both: distro-packaged versions in /usr/lib/lv2 and custom builds in /usr/local/lib/lv2/. In that case it is undefined which version is used.
