| 406951 | 2005-11-27 02:29:00 | That tutorial I referenced says there can be a delay of up to 10 ms before a note starts, which seems reasonable. I think it would be worth making sure that Sibelius is the only application running. Having an Internet connection active could be a bad move, for example. When I was working with realtime stuff (in smaller units than ms ;)), the first thing I wanted to find out about a new machine was how to turn off its OS clock, because my only use for the OS was as a programme launcher. |

| 406953 | 2005-11-27 09:36:00 | That tutorial I referenced says there can be a delay of up to 10 ms before a note starts, which seems reasonable . It is much much longer than 10mS, in fact I doubt that the human ear would pick that up unless perhaps well tuned i . e . a professional musician . I think it would be worth making sure that Sibelius is the only application running . Having an Internet connection active could be a bad move, for example . It is the only app running, and there is only a network connection to my router . Comp is a PIII-700 with 256 MB ram so it shouldn't have any problem handling a single channel of midi . why not try a midi to usb adaptor? Why? Can you explain how would that help? Sounds to me like it would be slower than a direct cable connection . Cost would also be a significant factor, they are not cheap . Cheers Billy 8-{) |

| 406954 | 2005-11-27 10:15:00 | PC-Chips with intergrated audio? Midi is directly affected by your audio processor (midi is just sending a note to the audio chipset,which then plays the closest match it has in its database of sounds), in this case its an oboard solution on one of the worlds lowest quality motherboards, and its not only limited in go juice and capabilities but its throwing all the work over to the cpu. Personally I would suggest that anyone wanting to do more with audio then just listen to Windows beeps buys a sound card.SB Lives can be had in Auckland for $50 odd, Though I would suggest an Audigy 2 Value edition, Just over $100. However, No garentee this will fix your issue, the comp could be poor at audio prossecing for a number of reasons. |

You're not wrong Metla, it certainly is a "cheap as chips' MB, but I bought a pair of these computers at auction for my kids a few years back when money was very tight, and they were only ever intended to do WP etc for homework. As it happens, they have performed remarkably well and my son stretches the on-board sound with quite a few activities without problems. I wouldn't put an audio board into that box, but I might put one into my present computer and pass that on to him when I get a new one myself. As I said in an earlier post, single channel midi shouldn't stretch the capabilities of even this crappy MB, and certainly not to the extent of 100+mS delay processing a single note. For heaven's sakes, it worked OK on 486's with miniscule RAM so a PIII 700 should have a reasonable chance of delivering the goods. I am prepared to be proven wrong, but my gut feeling says that it is more likely to by a synchronisation issue than a system capacity problem. I recall reading about something very similar during my early investigations before I got the adapter cable, but I can't find it again. (Sod's Law alive and well). :( Thanks to those who offered help, I'll skive off to a musician's forum and see what they know. Cheers Billy 8-{) :badpc: |

| 406956 | 2005-11-27 21:08:00 | Does Sibelius have some setting that compensates for this lag? If there is, you can effectively tell Sibelius that the MIDI events it receives are 100ms (or whatever) late and it should compensate. I know there is such a setting in Computer Muzys (which comes with the Computer Music magazine), though I'm not sure if it's for audio input only or both audio & MIDI. In the absence of such a setting, just record as normal. Then, once the track is recorded you can simply select all the MIDI events and shift their start time to the proper cue. From memory, Sibelius seems to only handle score editing - as opposed to Piano Roll or List view (of MIDI events). For that you'd need a sequencer as opposed to a notation package - Computer Muzys is one example, which is pretty good. Other free sequencers include Anvil Studio and Jazz++. In any of these packages (including Sibelius), your pieces can be exported and imported as MIDI files (*.mid). Hope this helps. -D. McG |

| 406957 | 2005-11-27 21:08:00 | 486 would have had a dedicated audio solution :p Anyhow, You may have just found the limitations of a low end board, especially if there is no info floating around the web related to the issue while using your nominated software. Or I could be way off, Which is why I put the little disclaimer in the prior post. Have you buy any chance plugged the KB into your personal rig to see if the issue rears its head there as well? |

| 406958 | 2005-11-28 02:42:00 | Thinking about it Billy, you might be able to detect 10ms. Sound travels about 1000 ft/sec (about 334 m/s at sea level,and normal temperature and pressure, for the metricated ones among us). You can locate close sound sources to better than 10 ft. |

Thanks Metla/Graham I have found that the issue is called latency, and using that descriptor as a search term opens up a virtual cornucopia of information, some of which is way too deep for this particular problem, but I see glimmerings of hope. I haven't had time to look further yet, but I am leaning towards the need for an audio card to get the best results. It will be a mix of sotware and hardware solutions I fancy, though I haven't given up hope of a magic bullet. :p Or maybe I might get my new computer sooner than I expected. :D Cheers Billy 8-{) |

| 406960 | 2005-11-28 04:49:00 | Perhaps an Acorn computer would help. That's what Sibelius was written for/on. ;) But I don't think you can avoid the consequences of a 300 bytes/second communication channel. | Graham L (2) | ||
