problematic playback od GT multispeeds
I'm not sure how problems and hickups are common for playback on real machine but considerable number of my works usually sounds broken, especially those ones composed with the latest GT release. What's the culprit here? Are GT compilations that cycle sensitive or what? :) During the release of Club Stylier and a few other multis I was forced to create false SID address working as a buffer and then copy values to proper registers but it's really unwanted workaround. Any clues? |

- HR Test SNG
- HR Test SID
A little test in single speed with high tempo. Instrument Attack 01 is useful for the first time I suppose, also in multispeeds ;) Try to experiment with editor hardrestart Attack and Decay for the best results. I stick to FF00 at the moment and instruments gained more pleasant and less gated restart. Thanks to this, instrument HR time can be shortened at least one frame in many cases which results in better clicks. I've managed to cut it to 07 in 4x and from 20 to 1C in 16x. Mind that short instrument Release makes fast, non legato passages broken.
I strongly recommend redownloading my tests in order to catch the difference - playback became almost error-free and clicky in a good way. One thing that bothers me is little slowdown in First 16x test - too CPU extensive due to full SID buffer in each call?
Another 16x test also revealed slowdowns in compiled sid:
- Clicky Drums 16x SNG
- Clicky Drums 16x SID |

Hard restart! Oh Noes! /o\
:D
I keep moving further and further away from using HR. I just find that in many cases it cuts too much sound between notes and gets to sound a bit too stiff.
Ofcourse it's good for some things... I know..

Linus, my pleasure - it's splendid! :D
Soren: GT used to have no restart once and it was a big nono ;) You can disable HR in instrument anyway :P |

Linus: Did you use the -g command to change the center pitch? The tuning sounds a bit higher than the usual 440 hz. |

McMeatLoaf: I don't think so. In 16x multispeeds arpeggios can work so quickly that you get a one welded tone together with aliquotes. That's one of the tricks for multispeed instruments - in wavetable you put e.g. base pitch and two semitones up in loop, you get one semitone up as a result but its perceived finetune relies also on waveform, pulse width, filtering etc. |

Jammer: Either something was not good enough in no-hardrestart GT, OR it was the people using it. :D
When using sid buffers, and doing that well, no hard restart is quite neat. But ofcourse still tricky to play with. |

Thanks to Soren I started abandoning HR from my lead instruments a while ago and they really benefit from it. |

Well, I prefer setting Attack to 1 or 2. The same effect in GT, no messing with HR ;) |
