No, the first song that is being played is without the high sound. Then, if you stop the song and you try another song, you constantly hear this high sound. And I believe it even continues if you stop this second song 
So the annoying sound does stop? 
When entering the voice menu's I sometimes hear nothing at all until I leave the menu and re-enter it. Guess my MoonsoundInit and Silence routines are not 100% bug free, hehe.
Maybe the high sound only sounds with TurboRRRs. I have changed my Silence routine. Does anyone know a way to reset the opl4? 
Anyway, is there somebody out there with more than 128KB Sample ram? How much Sample RAM does Realfun find in such cases?
I have started coding 'Realfun2' (this is just a codename, ofcourse. The release version will be called 'Realfun' 
).
Main features:
- 16 channels, 256 tracks, 384 positions.
- 256 voices per voicebank, of which 32 voices can be used in a song.
- All voices have to be from the same voicebank.
- New characterset (ok, I've just added an inverse set 
)
- New default colorscheme.
- Waves.
Other improvements:
- No more [q] and [w] to define a block. (No, the new combinations are not [ctrl]-[b] and [ctrl]-[e] 
)
- No combinations, or programs or whatever they're called. Only 'single' voices.
- It won't be possible to load 'Realfun probeerversie' or Moonblaster songs.
The original 'one voicebank per song' idea I had in mind for Realfun will be implemented. For everyone who actually tried the 'probeerversie': Noticed the FM voicebanks per song? Heheh, In case you didn't like the idea: things just got worse.
And I will even implement a vertical orientated track editor. 
I may add some midi functionality like FAC Soundtracker Pro...
Thought it would be nice to let you all know not to expect anything anytime soon
Nice for keeping us posted. You might consider getting a stand at Tilburg to demonstrate your most recent version of RealFun2
