![]() Do either of you have a suggestion? Really, all I need is the basic collection of typical GM sounds that will run on an XP machine (without the time-lag, of course!)īut again, many thanks for your comments. You mentioned downloadable alternatives, but I spent hours Googling today and couldn't come up with anything that would do the basic GM sounds. You know, I kind of like the sound of the Windows GS Waveform Synth. But unless I'm an absolute peabrain (a distinct possibility), it doesn't seem to be of use with the MIDI-OX or Jazz++. Thanks to both of you for the lucid explanation of what's going on with the Windows GS Waveform Synth. Post by Thomas_Henry on Oct 5 th, 2007, 12:13am (My WinXP machine has 31 processes running, including about 6 I don't really need, and four that I don't run when making music.) It will also load soundfonts and you can find GM fonts around if you search.Īlso check your computer is running as few unnecessary processes as possible. However, there are plenty that are standalone, such as rgc:audio's sfz. There are literally hundreds of free software synths that can be used with ASIO (usually through a "host", as most of them are "VST" plugins). The Windows MIDI Synth, however, is often a problem as it's designed to use the default Windows driver. ASIO is more widely supported and there's a free "Asio4All" driver that can help with many soundcards. ![]() If you want to get into real time audio production, you'll need a soundcard with real time support - either WDM or ASIO. It's just designed for the one job, so that's all it does. (Your computer is also doing a lot of other things than playing sounds, all needing time.)Įven with outboard gear, any digital processing will work this way. Lowering the buffer size makes your computer work harder - it has the overhead of passing buffers around more often, which is why the larger size is chosen when it doesn't matter. With large buffers, this can take anything up to half a second. Now, if you're trying to create sound in real time, you have to wait for a buffer first to be filled, then processed, then played. Processing runs faster than playback (by a factor of 10 or more - CPU speed isn't what holds you up). Processing happens on one buffer whilst the previous one plays. ![]() In order to provide this on a lowest common denominator basis, Windows is generally set up with large "buffers". With the above, particularly DVDs and games, keeping the audio stream steady and synchronised is more important than responding in real time. Standard PC domestic use is playing back CDs or DVDs, or playing games - not creating audio content. Post by Peter L Jones on Oct 4 th, 2007, 1:13pm This is why I still prefer to use outboard MIDI gear for this purpose. Even then, there will be some real-time lag, but it can be synchronized with pre-recorded tracks. If you want to be able to do real-time performance of MIDI you'd probably be better off using a dedicated sequencer that can load DXi or VSTi plug-ins. There is a large amount of processing that must be done before a pre-recorded wave can be played back at a certain pitch (resampling) and velocity. It's pretty normal to hear a latency lag when playing real-time through a software sampler (builtin GM sounds). Post by Jamie OConnell on Oct 4 th, 2007, 11:47am Has anyone else seen such behavior? And if so, is there any way to correct for it in MIDI-OX? I suspect the time-lag problem is coming from Windows XP or the way in which GM is implemented on the machine. But there is a noticeable lag between when I strike a key on the MIDI keyboard and the GM sound appearing, on the order of 100 mSec or so as a rough guess.Īfter some experimentation, I believe MIDI-OX and my USB MIDI interface to be behaving okay. I can make the connection all right and hear the GM voices, thanks to the easy and intuitive behavior of MIDI-OX. I use Windows XP and an E-MU USB MIDI interface. I simply want to connect a MIDI keyboard to my laptop computer and play the GM voices within it. Maybe I'm the dunce in the pack and am missing something. I've spent a lot of time looking over the archived messages and am surprised someone else hasn't run into the problem I have. I've been having a real hoot with it on my newish laptop and all the music gear I've accumulate over the years. I have to confess, I'm amazed at how excellent the MIDI-OX program is. ![]() Post by Thomas_Henry on Oct 4 th, 2007, 12:17am (Message started by: Thomas_Henry on Oct 4 th, 2007, 12:17am) MIDI-OX > Questions and Discussion > Delay or Lag When Playing GM MIDI-OX User Forum - Print Page MIDI-OX User Forum () ![]()
