Delayed Sound

[gordon]

Greetings from Wagga Wagga, Australia.
I submitted this topic a few days ago and can't find it on the forum, so here we go again.
I am using a laptop computer and a Yamaha PSR5700 keyboard. Have the sound coming back through the computer, but with delay, which for an old Hammond/Yamaha player is a problem. The question is ... can this be stopped? Is it in the digital sampling ? I would be grateful for some answers. Gordon

Hello Gordon

Your question is a common one for new Miditzer users. There are a number of aspects that contribute to the delay and these vary considerably depending on your MIDI interface and the efficiency of your PC.

There are some settings within Miditzer that can improve the response. See the attached notes.

There are also a range of configurations that can be made to your Windows environment that can assist. Forcing Miditzer into a high priority mode can also assist. See attached notes.

Please let us know the specifications of your computer, and also how you go with these adjustments or further questions.

Do also check the "tone" setting or the "velocity curve" settings.

I use a Casio WK8000 keyboard for the solo & I notice that if the tone is set to "Drawbar Organ mode", latency (delayed sound) is much lower than if the tone is left on the default "Stereo piano".

Perhaps, the "velocity curve" of the default "piano tone" in some retail keyboards & digital pianos do contribute to the increased latency (delayed sound) when playing the miditzer.

Since my discovery, I have always use the "organ mode" on the Casio keyboard to play the miditzer. I have also turned off the "velocity setting" of my m-audio Oxygen 61. This keyboard now instantly output note-on at constant value of 64 making it behave like an organ keyboard(rather than like a piano with delayed hammers).

Tried all of the above ( buffer down to 4) and still a massive delay making it near impossible to play anything above 160 bpm which is a damm shame as the samples are fantastic on the 260, "tower ballroom" quint and tierce are to die for. Running windows 7 ,250 gig hd,3 gig memory and only running miditzer on it. Midisport 2x2 interface for the yamaha hx3 (accomp,great, pedal)and casio keyboard(solo) seems to be a greater delay on the solo

Windows 7 is your problem.

If this is to be a dedicated Miditzer computer then I would suggest digging up an old copy of XP and license code. Another option would be to load a virtual machine of XP running in your Windows 7. (Still needs an XP license)

This thread will give some explanations as to what is going on and why.

It might be cheaper and easier to rescue an old computer that still has a copy of XP and use that as your Miditzer computer. It doesn't take an uber-computer to run the Miditzer.

yes i am finding windows7 ultimate is not compatible with anything ie my midisport 2x2 ( although it is working) my emagic mt4 is impossible with windows 7 even my epson r300 cd printer, just done a rough midi recording of tico tico lol and it seems the faster I play the slower it gets, got to a stage where my left hand was in another room lol
gonna try xp see how that goes can always re install windows 7
i played pipes many times some years ago a wurlitzer 3/10 ( sadly in storage now after being moved from venue to venue the last location was the ritz ballroom in brighouse west yorkshire)
will keep you posted
thanks for your help

There are two separate issues occurring here.

Your external hardware issues are most likely related to 32 bit and 64 bit operating systems and the specific drivers required. Most XP installations were only ever 32 bit so rarely became an issue. I would go so far as to say now, that most Windows 7 installations are 64 bit (to allow use of more than 3GB RAM), however many users are not initially aware and learn the hard way trying to install older hardware they had no trouble with before.

The audio delay is to do with the various internal software connections that lead to getting sound out of your computer. Windows changed these paths in "Vista" and "7" from what worked quite happily in 98 / XP.

YEEEEEEEEEEEEESSSSS! Success!!! after getting rid of windows 7 permanenlty!!! ( and it didnt want to leave lol) hard drive format, installing xp and service pack 3, driver updates and downloads it finally worked no delay hardly at all now and the sound is richer and fuller than before, still had to tweak the buffer but I now have a glorious 3/19 wurlitzer in my lounge with stunning surround sound. The reverb effects with miditzer put hauptwerk to shame.
i will be purchasing a license
thanks for all your help guys very much appreciated
regards mark.

Hi Mark

Thank you for the feedback and congratulations on your success. I can never fathom why installing a Windows operating system needs to be such a labour intensive process.

Have you tried the "Priority" setting in Windows also?

For the record. Windows Vista and Windows 7 don't handle all sound functions poorly. It is just that the dSound (legacy DirectX) output from Fluidsynth is handled poorly through an emulation process in an effort to provide backward compatibility.
