Hard Restart?
Hi, can anyone explain me please what this Hard Restart is all about and why does it seem to be that important? This confuses me. |

The ADSR of SID has some kind of bugs (delay and bundary bug) that will make the sound to go muted when playing a "new note". You can avoid this by selecting some values of ADSR instead of others, but if you want to not worry about this, you can use some technique that makes the new notes to start correctly in every case.
Hard restart is a tecnique that can be implemented in many way: looking into old post you will find something about even a sexy-hard restart.
However somethimes it is even mentioned Soft restart when it is implemented as based tecnique (like releasing the gate two frame before the new note start), comparated to the more sofisticated in the hard restart.

I don't find hard restart very important anymore.
And often I even don't reset oscillators.
This gives less unwanted clicking.
One just needs to be a bit more carefull with ADSR settings and I believe that using a sid-buffer in one's music routine will make things just a bit more stable.
The good thing about avoiding HR is that things become more lively, especially when doing melodies. Furthermore you can trig notes faster and in general you will have less soundloss between trigged notes.
Still, I can understand why some people want to use HR on things like drums. It is easier that way.

So I don't really have to use this Hard Restart thing when the music and instrument are sounding alright then? |

Leticia: Exactly, but it might require a bit of work concerning ADSR settings of your instruments. |

Still, if you are new to the sid, you just ought to not think about it, there is plenty of other things to learn first. |

In fact there are many things that I still have to learn, but due to some musical knowledge I'm already able to do some melodies. I play the piano a bit ;) |

Yeah.. There are also a bunch of other threads dealing with hardrestart on csdb. Just search for "hardrestart" in the forum search, if you're interested. |

imho this whole hardrestart thing is a bit overrated and blown out of proportion. its just one of the many details that may or may not be useful depending on what you are planning to do. and there are many cases where NO hardrestart is the preferred option (unless you *want* that mechanical stakkato like expression) |

Traditionally... To have access to hardrestart in the player one is using — or better yet, actually understanding the ADSR bug and how hardrestart works — is what separates the lowlife scums and lamers from the elite and the sages in the world of SID. Hence, using hardrestart is a scene sacrament that must be blown out of proportion if order is to be maintained. I vote for continuation of this ritualistic practice. |
