@d-healey Thanks again, will try this option for now. But hopefully Christoph will fix this in some future updates.

@d-healey unfortunately, Hise still crashes when I turn octave or semi tone knobs.

@Lindon I tried to add per-filtering before and after, it still crashes.

@d-healey oh, so it's not just me :) Thank you for taking time to figure out this issue.

I don't think the user will go that low, but it possible that someone accidentally find this bug (like I did) and will be annoyed by ruined session.

@d-healey it's on top, after the Interface script. And Transposer is on Sampler level.

BTW I switched to MBP and the issue is still there. Midi keyboard is the same.

@d-healey Well, when I set to -5 then only C-2 crashes Hise, C#-2 and above - all good.

But when I set -6, then it starts crashing on C-2 and C#-2

aaaaand if it's -7, then it starts crashing from D-2. Like there is some dependency

@d-healey If you mean to test it with the mouse then yes, it crashes Hise.

@d-healey I rarely use it and I don't know how to switch octaves, it's always plays higher ranges.

Here is the project. NoteRangeTest.zip

@d-healey Will do that in few minutes. If I do it with the mouse like you, then it works fine, but when I press the lowest key on the midi keyboard it crashes.

@d-healey Tried that and Hise crashed.

And for the first test, I did it wrong, I only played with Transposer.
So when I set just one sample to C3 and then press C-2 and set Transposer lower than -4 Hise crashes.

@d-healey With just one note it works fine with any Transposer value. I think it crashes when I go to a non-existing octave below C-2.

I'm using develop branch, but to the freshest one, v2.1.0

@d-healey Most of the samples are 44,100 Hz, 24 Bit, Mono, PCM, some sample maps use 96,000 Hz samples. But this happens with all of them.

@d-healey Just tried - I set the lowest sample root note to C-2 but the issue is still there.

@d-healey Here is the snippet. It works fine with Sine generator, the problem is with Sampler.

When I set Sampler's Transposer to -5 or below and press C-2 key on midi keyboard Hise crashes.

I also noticed that when Transposer is set to -1, -2, -3 or -4 there are no crashes, only at -5 or below.
And also from -24 to -13 there are also no crashes. The range -5 to - 14 makes Hise crash. Kinda weird, maybe there is something with my midi keyboard.

My samplemap looks like this if this if this helps

@Lindon This seems like the solution https://forum.hise.audio/topic/1035/ignore-note-range/2?_=1676312033909

But it doesn't fix the problem. Or there is another way to fix that?

@Lindon Thanks, will try to dig in this direction!

Hello

I'm using Sampler and built-in MIDI Transposer. When I set Transposer to -12 (or below) and press any key below C-2 Hise instantly crashes.

I guess this is because I'm going to a non-existing octave, but how can I prevent this?

@DabDab I'm using MIDI scripts like these

https://forum.hise.audio/topic/1122/midi-transpose-cents/2

https://forum.hise.audio/topic/2714/adjust-semitones-frontpanel/9

And there is built-in Transpose MIDI script in HISE

Not sure how it works, but I accidentally clicked "+" on LoopEnd and that fixed the problem! Looks like Sampler counts sample length differently or something.

My loop end point is exactly at the end of the sample so I shouldn't be able to increase LoopEnd position by clicking "+", but all samples have +1 "gap" at the end of the sample.

And if the loop region is in the middle of the sample, then "+1" or "-1" on LoopEnd or LoopStart fixes the problem.

Maybe this will be useful for someone :)
