Any fixes for sustained notes in Modo Bass and misaligned tempo in Modo Drums?

It has been over months ever since i have bad experiences using Modo Bass and Modo Drums in FL Studio, even in the latest stable version (25.2.5). My problems are that when i play the bass in Modo Bass, there’s a chance a note will be stuck and play indefinitely until it fully decayed, which prevents me from using Modo Bass. In Modo Drums, there’s a chance that when i playback a song with Modo Bass in it, there’s a chance that the drums will slightly misalign with the tempo, and slowly getting worse until it’s completely dislocated.

I have tried using using fixed size buffers in FL, but it seems like it doesn’t work.

Have you reported this to IK Support? I’m sure they can troubleshoot with you and find out what is going on.
