music with tremolo-effects ?
Hi,
I recently fell over some old workdisk of mine, which had some testsongs trying the tremolo-effect. Now I wonder if there are already other tunes featuring that ?
ps. if you don't know - tremolo is some kind of volume-sweep on a playing instrument |

@nata: you're wrong. The principle discussed above by Drax and so on does indeed allow for fade out. |

F.ex you cannot set a gate-off while the tremolo is running. (Of course you can, but it won't help) |

@nata: The very opposite is true. You HAVE to fiddle with the gatebit in order to achieve a tremolo. (The editor you are using may hide this though, and do it automatically within the player code, not making it visible to the user.) If you want me to explain how doing tremolo works technically within the SID, then just send me a PM and I'll do that. |

Of course I know how to make tremolos. (gatebit ON/OFF + ADSR "manipulation". (In fact, it's quite easy with certain editors)
I try to do some very fast tremolo (it swings similar fast to a nice vibrato), but I need to start it loud and fade it out to silent. :) |

@nata: ok, fine, but I am unable to grasp how you on the one hand say you know how tremolo works, and on the other hand say you are unable to do a tremolo that fades out. Obviously, you do not understand it fully. No criticism implied. Anyway, the "secret" lies in the ADSR manipulation part. Just choose suitable values and you'll have a fade out. You'll have to make sure that the envelope goes a little bit more down than up during it's lifetime after being trigged initially... Simple as that. (And gatebit is of course switched on and off all the time to achieve the tremolo.) |

I already have the suitable values for the fast swinging tremolo.
Unfortunately I cannot take some other values to fade out. The tremolo must swing always with the same speed. (There are certain tunes that seek for an accurate conversion) :D |

lo,
I don't get it either. There is no problem in fading out instruments using tremolo.
Care to elaborate?

Never tried it the way Cadaver explained. Only some primitive waveform and pitch switching which cannot really be called smooth. Thanks for sharing, have to test it on higher A/R values ;) |

Example "sng":

It works if I use the volume fader, but of course this makes no sense. :)

Hrmpf...
I've tried to to the same effect with my favourite NES Tracker and it worked without any problems. (Fast tremolo + Volume fading to silence)
It's not a problem to make a similar tremolo with the SID but the volume fading seems to be impossible.
In fact I've never heard a C64 tune that uses a similar effect.. :) |
