If you have windows 10 and have installed the latest RC: RC5 in either 32 or 64 bit version, we need a feedback in the functionality of ZynAddSubFX default presets.
Please go to this page
https://soundcloud.com/musikbear/issuewin10-zasfx-rc5
I have recorded a few notes with 5 default ZynAddSubFX presets.
Now DL the project:
IssueWin10_zasfx_RC5.mmpz (attached)
Open the project and listen carefully to the playback
What i need to know from as many win10 users as possible is:

1) The playback quality -Eg it should sound -exactly- as the recording!
-If it does not -please record the erroneous result and upload to soundcloud
Add the link to your comment

2) The chosen backend. SDL is still what is suggested

3) Latency setting in Buffer-size
-You find that here: Edit| Settings | Buffer-size

4) The subversion of your win-10
