Notes hanging in Reaper (in Sfizz 1.2.3)

Opened this issue · 5 comments

Hi dear devs,

I just tried the new version of Sfizz 1.2.3 in my DAW.
I loaded a patch of Virtual Playing Orchestra and played a little. Soon there were hanging notes.
To test it, I returned to version 1.2.2. -> Loaded the same patch -> No hanging notes.
To be absolutely safe I retried version 1.2.3 and there were the hanging notes again.
So, I think there could be a relevant bug in 1.2.3 (perhaps in combination with Reaper).
For me no larger problem, because I use 1.2.2 as long as this is fixed.

my configuration:
Win 10 Pro
Reaper 7.11

Nevertheless hands up for this wonderful piece of software. Thanks devs !

I experience hanging notes both in Ardour and in Bitwig, both on Linux, pretty sure this is a regression in 1.2.3.

@paulfd I let this here because I'm not sure if it's a library or plugin issue.

Same issue, Linux/Ubuntu-clone 22.04, Reaper 7.15.

In OBS, there only is the latest version of the prepackaged deb files (in my use case), where could I find the previous ones?

Thanks!

I have the same issue - with a pretty fresh Kubuntu 23.10 64 bit installation, trying both with Ardour 7.5.0 and 8.6.0, using ALSA and the headphone jack of my integrated soundcard as audio output.

I tried with different sample rates, buffer sizes, changed my CPU frequency to "performance", nothing helped.
It did made a difference whether I used the VST3 version vs. the LV2 version though - in the latter, when sliding with my left mouse button down over the piano roll in sfizz, this was enough to cause at least 4 notes to get stuck, while in the VST3 version this was only happening rather randomly (and not necessarily during "heavy load") when receiving MIDI input through Ardour. However, while the LV2 version could be "unstuck" by sending a MIDI Panic through Ardour, the VST3 version had to be completely "disabled" and reenabled to "unstuck" the notes.

I checked the MIDI signals going into sfizz using the MIDI tracer - and can confirm that all NoteOn events that came in also were followed by a NoteOff (for the same note that is).

I hope these additional details help to narrow the issue down. Unfortunately, I also have no access to a previous version that doesn't have that problem.

EDIT: I just checked out the sfizz-ui repository (and the sfizz submodule) at version 1.2.2 and built it manually, then tried the VST3 in Ardour 7.5.0 again and it worked - so I suppose it's a bug in 1.2.3 after all. I also used the Virtual Playing Orchestra for testing, by the way.

+1, with sfizz 1.2.3 from Fedora repo, Virtual Playing Orchestra, Ardour 8.6, ALSA backend. Problem does not manifest on 1.2.2 built from sources.
