    Lightbulb Now It's my turn to ask these kind of questions

    Today I took the liberty of purchasing a USB MIDI Interface.
    Thusly I'm qualified for membership in the esteemed club of
    people-with-questions-about-MIDI-related-stuff.
    Must say I'm honoured.

    Anyway, I state my problem:
    When I play something on my electric piano the output from
    my speakers isn't synced with my own playing. Rather confusing
    really. It's only a matter of fractions of a second but it's enough
    to make me loose myself during recording. I've consulted the
    Sonar 7 Help topics (since I use Sonar). It says that one could
    mute the Line-in in the soundcards mixer to prevent this, but it
    was to no good.
    I am using a USB extension cord for the Interface since my piano
    was to far away, could that be it?
    Otherwhise I'm clueless.

    I wont do any namedropping here regarding hardware and
    such since I don't know what to mention. But if anyone
    could help me I guess it would be easier.

    thanks in advance

    If you are listening to the output of your recording system, it could be causing the delay. there are actually very few systems that can monitor the output while recording with no delay. try listening to the input. if you already are, or if you are listening to your piano directly, then I don't know....?

    are you recording audio? or midi, or both?

    if you are recording midi, make sure input quantizing is off.

    can't think of anything else.
    can you give me some more details

    You're using your keyboard to trigger (for example) the GPO Steinway piano?

    Your sound card adds latency (the delay you hear) allowing it to process the incoming midi stream, locate the correct samples, and play them back without dropouts or distortion.

    Hopefully you're using a sound card with ASIO drivers. You'll need to configure the latency on this to a lower amount.

    Hey Felix -

    Since you say you're new to MIDI, I thought I'd give you a high level overview of latency.

    That's the amount of time between when you hit a key and when you hear something. Sonar will let you turn it down to practically 0, but then you will have a new problem. Playing more than one or two notes may cause pops, crackles, or crash the sound engine. Crashing the sound engine, by the way, is not a big deal - you just click it back on again.

    But the crackles, pops, and crashes make it impossible to get anything done. So you raise the Latency until you find a happy medium.

    How low you can set the Latency depends on your computer and your soundcard's drivers. That's one of the reasons to invest in a good card - to get good drivers.

    Have you run Sonar's Wave Profiler? That runs some checks on your audio card and tries to set you up properly. Then you can try lowering the Latency even more until you get the snaps, crackles, and crashes. <--- Sounds like a breakfast cereal for computer music enthusiasts!

    Latency is the problem here. If you are just playing then listen to the input signal, however it becomes a problem when trying to play along with a track that is already recorded and playing back with you.

    Depending on your computer and soundcard this can be a problem. You need to be in Duplex mode for the soundcard and you need to get the latency down to a usable level.

    Try ASIO4ALL, its freely available on the net. you can change the size of the buffers the reduce the latency but you may get crackles and pops. Keep reducing until this occurs then go back one level. Do Not Use the microsoft driver, its ridiculously slow with a latency of 100's of milliseconds, you need to be below 20. Its not designed for midi music but games and such like.
