Issues with the VST synth Ronan Fed RF-AB303

Describe the bug
The VST synth RF-AB303 from Ronan Fed does not work pass the basic factory settings. Changing presets does nothing to the sound, neither does touching knobs. If a knob is touched during playback, or the preset changed, it will cause the playback to stutter and freeze for a while, and musescore will be mostly unresponsive for that time (you can still select stuff and displace notes, but the playback is completely frozen)

To Reproduce
Steps to reproduce the behavior:

1. Download and load RF-AB303 (https://ronanfed.rf.gd/RF-AB303.html)
2. Write some random notes
3. Initiate playback
4. Try to change from init to another setting during playback, or turn the knobs.
5. This causes playback to freeze.

Expected behavior
The VST should work as it does on other DAWs.

Screenshots
First is turning a knob, second is changing presets outside of playback, second is changing presets during playback (notice how the sound doesn't change)
