Sometimes notes don't play when playing live

Hello,

I noticed some strange behavior today while playing the GigaPianoII sample that ships with GIgaStudio3 Ensemble. I noticed that sometimes when I play a key on my keyboard controller (Roland A70), I do not hear a corresponding sound come from LinuxSampler. This happens intermittently, and if I strike the same key again, I usually will hear the corresponding note play. I've observed this using both ALSA MIDI and JACK MIDI. I've also confirmed that I don't get this kind of behavior when playing a different sample, such as the "masetro concert grand" sample available from this site. Interestingly, I didn't observe this behavior until playing the bass line in the introduction to "Linus and Lucy" by the Vince Guaraldi Trio (simplified version, in C major). When playing this bass line, which consists of alternating between 2 repititions each of an arpeggiated 3-note chord in the left hand, often times one of the notes in the arpeggiated chord will not sound in the second arpeggio of the chord, even though it sounded just a second before when I played the first arpeggio.

I first observed this using the latest release versions of libgig, liblscp and linuxsampler. I also was able to reproduce this behavior using the latest CVS versions of these packages.

Any suggestions would be greatly appreciated. Thanks.

First I would suggest to check whether the respective note on actually arrives. Latest CVS version of liblscp & QSampler supports a green MIDI indicator LED for each channel strip which will flash up on note on / note off events.

If the note on really arrives, you may want to investigate the gig instrument with gigedit. If there's really a bug in LS regarding the playback accuracy to the gig format, then you could modify the respective part of the instrument with gigedit to find out what the problem exactly is. Just don't forget to backup your gig file before doing so. ;)

Hello,
Thanks for the suggestion. I just built qsampler from CVS and I built liblscp from CVS yesterday. I see the green MIDI indicator LED, but it doesn't light up at all, even when I know it's receiving MIDI data since I can hear the output of linuxsampler. Is there some option I need to enable this LED monitor?

Thanks!

Not really. If you see the following in qsamplers configure output:

LSCP channel MIDI event support . . . . . . . . .: yes
LSCP device MIDI event support . . . . . . . . . .: yes

it should be fine. Maybe you don't use latest linuxsampler CVS version? What version does LS print out on the console?

Thanks for your response. It turns out that QSampler was linking to a different libscp library than the one I had built from CVS; I had set LD_LIBRARY_PATH appropriately for QSampler's invocation of linuxsampler, but had failed to set LD_LIBRARY_PATH for QSampler's environment.

Anyway, I've verified visually with the green LED that the note-on's/note-off's are being received by QS even at the times when I hear no output corresponding to my key strikes.

Are there any settings in particular you would suggest examining in Gigedit? I can't think of a setting which would result in seemingly inconsistent, yet readily reproducible, behavior. I can now regularly reproduce the behavior with a simpler test case: Playing 16th notes on the lowest C on my 76-key controller (not sure what MIDI note number that corresponds to) will result in one out of every several key strikes not producing any sound, even though I see the MIDI note-on/note-off being received by QS.

Thanks again very much for any suggestions.

An additional piece of information: I've noticed that for the times when I strike the key and don't hear a sample triggered in response to the note-on, I do hear an (action noise) sample triggered in response to the note-off.

I can't tell you much about why it doesn't alway play it, since I don't know how the instrument exactly looks like. It heavily depends on what kind of dimensions are defined for that particular key / "region", how those dimensions are splitted and the setting for each one of those resulting "cases".

Thanks for your reply. I examined the Gig in question (Tascam's GigiaPiano2) under Gigedit, and also with Gigdump, and found nothing that I think would explain the behavior I'm observing. There was no random dimension that might explain the seemingly non-deterministic behavior I've been observing. The region in question seems to exhibit this behavior only for one of the velocity dimension regions. However, this region and dimension region do not appear remarkable compared with the other regions and velocity dimensions

I rebuilt linuxsampler using a high debug level, and have captured a log file, pasted below. Of the 7 note-on events, the 5th and 7th note-on's resulted in no sample being played, or at least, no audible sample being played, although I believe that the (piano action/hammer noise) samples were played for the corresponding note-off's. I was driving linuxsampler with a virtual keyboard that was generating the note-ons with the same key number and velocity every time.

Is there any other information I can provide that would help debug this?

Thank you!

Hmm, that's strange. I'm pretty much sure Andreas should have that instrument and if he finds some problem he usually fixes it my himself or at least tells me about it. I will ask him.

Could it be that you ran out of voices / streams when that happens? If yes, it could be a bug in the voice stealing algorithm. You can also try to use another voice stealing algorithm, by using the appropriate configure parameter of LS's configure script (see ./configure --help).

Anyway, as I don't have that file, can you probably assemble a small (/copyright non-infringing) .gig instrument which reproduces the problem?

Hello,
Thank you for the suggestions. I don't think it is a running-out-voices problem, as I can reproduce this by simply repeatedly playing C2 and no other notes, or controllers (e.g. sustain pedal). Nevertheless, I tried rebuilding linuxsample using "--enable-voice-steal-algo=none", but still observed the same strange behavior.

I will attempt to use gigedit to pare down the GigaPiano2 .gig instrument to just the offending region. If I succeed in reproducing the issue with such a minimal .gig instrument, I will post it here.

By the way, I wanted to know if you were able to ask Andreas whether or not he observes the same behavior in his setup.

Thank you very much again!

Hello,
I sent you a PM regarding this.

Thank you.
