Has anyone ever had issues with Analog dropping (i.e. not playing) certain midi notes?
I have the standard default template (2 midi, 2 audio) with "Basic Analog Bass" on track 1.
I have a one bar midi loop (120 bpm) with two B0 notes (1/16 notes at 1.3.2 and 1.4.2).
I play the clip and all is ok for a while, then it starts dropping the first note and only plays the second.
Can anyone reproduce this? (v11.3.2 on Apple M1)

Yes, i encountered the exact same problem/behavior with analog a few days ago.
I tried and experimented a lot to get the problem solved, an after i gradually increased
the audio buffer size (from initially 128 to now 512), the note-dropping stopped...

On which Live version? L11.3.3?
Any CC64 (sustain pedal) involved in those clips?

Live 11.3.3 here, mac mini 2019, no cc64 or anything else involved.
It apeared to me first when i programmed a snare sound in analog and made a simple 1 bar 1/16 loop
with triggering the snare at 1.2 and 1.4.
For a few bars it plays the snare-sound regulary, than after a short while it suddenly begins to randomly drop some notes every few bars.

Good to know it's not just me. I too tried lots of things to get to the bottom of it. I went back to the default Analog preset but it would still happen. I even put it in a Rack with another instrument in parallel. Analog would stop playing one note while the other instrument was just fine. Weirdly, if I adjust the temp by 1 bpm during playback, the problem stops. More rarely, I've heard both notes but with odd timing. I too am running 48kHz/128 by default.

If it's not about a limited polyphony setting, then you're probably better off reporting to Support.

I've raised a support ticket but if anyone else sees this please comment here...

I made a quick video to show the problem:

following your video i could recreate the dropped note. sometimes a note is missed, other times it's played late.

Support have finally got back to me today and admitted this is a known bug and is under investigation.

This appears to be fixed in 11.3.10 although there is nothing explicitly mentioned in the release notes.
Anyone else confirm this??

Yes, i can confirm, i did some testing yesterday and the random note dropping really seems to be gone.

Just noticed this happening to me with Analog on Live 12.0.5, Macbook Pro M1, Sonoma 14.5.
It happens with buffer size 32, but seems to be okay with 64 and higher.
Haven't noticed it before (but haven't specifically looked so it could have been lurking there all along).

Did anyone else experience this one lately?

It happens here, too, similar to what Lincolnkid saw. It happens only with a buffer size of 32 (which I rarely use) in Windows 11 23H2 and macOS Sonoma 14.5, Live 12.0.5. I cannot reproduce it in Live 11.3.25 or 11.3.30b1, so it looks like a regression.
