Allow more instruments to play back bends (e.g. synths)

Issue type

General playback bug

Description with steps to reproduce

Only string instruments allow bends playback rendering on MSS side. It should be rendered the same for all instruments, irrespective of their name (ex: synths should allow bends to play, currently they won't).

Check this comparison: same audio (MuseSounds Acoustic Steel Picked), different instrument names.

Start with Issue_34055_bends.zip and reproduce the comparison between the string instrument and synth using the attached audio. Trace where playback decides whether bends are rendered based on instrument name. Done means the same bend playback works for synths and other instruments as it does for string instruments, while preserving the existing behavior.
