      @Christoph-Hart I sent you the example project by email and in the private message on the forum

        @CosmicWolf The release time of your envelope is set to 0ms. Your sampler's voice count is 128 with a fade time of 1ms. These could be the cause of the issues. Test the plugin in Reaper, also try as a standalone application.

          Also, 1024 is a very low preload size (basically 2 audio buffers), if you're playing fast notes, then the streaming engine might choke on this.

          Does it also happen with the default values (8192 preload size + 4096 streaming buffer size)?

            @Christoph-Hart I tested the suggested adjustments, including setting the preload size to 8192 and the streaming buffer size to 4096. I also adjusted the envelope, voice amount, and fade time. Despite these changes, the issue persists. What puzzles me is that this problem does not occur with the AU format in Ableton Live.

                @d-healey I tested the plugin in Reaper, and the issue does not occur. This suggests the problem might be isolated to how Ableton handles VST3 plugins, particularly during looping.

                  Or perhaps there is a setting in Ableton that could solve the issue - as with some issues in FL Studio.

                    Does it also happen with a sine generator?

                    I know that Ableton is doing some funky stuff when wrapping the loop (it splits up the audio buffers) and I've fixed a few things related to this some time ago.

                      @Christoph-Hart The problem is also occurring in the Sine generator from what I tested here, it seems that it generates duplicates when it loops

                        @CosmicWolf Alright I spotted an issue, it was in fact the case that Ableton splits up the audio buffer at the loop point and there was a rare code path (if the next buffer is using the full length which apparently only happens at Ableton Live loop points), then it will ignore the MIDI messages from the last buffer which ends up in muted notes.

                        Feel free to pull the latest change and see if the problem persists. I could reproduce it with the Sine generator inside the VST3 build of HISE and it's gone here now.

                          @Christoph-Hart I just tested the latest update, and I’m thrilled to say the issue has been resolved! The changes you implemented completely fixed the problem, and everything is now running smoothly in Ableton.

                          Thank you so much for your quick response and support. It’s incredible to have such an active and dedicated community here. I truly appreciate all the help!
