I would be concerned about your usb hub as well. It's possible that you get less crashes with the 1.0 hub because it is slower and your computer can keep up with it(just an idea). I would not continue to use a 1.0 hub. Both midi and audio need constant streaming. Having both on a single usb controller is probably not a good idea.

How-ever, I would try to get reaper going with your USB 2.0 hub or no hub, just direct. Put together some tracks with your keyboard only plugged in. Close Reaper, unplug your keyboard, plug in your mic, restart Reaper and see how that records. It should work.

What do you use to listen to your computer audio? What AUDIO DEVICE?

at the moment, I listen back to audio on the Behringer mixer - it works both ways simultaneously. Infact that works ok. What does not work well is the analogue to USB which is its most important function as far a I'm concerned.

but I'm just feeling my way here. In fact, self-synch monitoring while recording is completely impossible with this set up because, even if the system didn't crash with the duplex running, there is such big time lag that you'd be completely thrown.

...blue screen said: driver 64 ST (something like that)

Reaper is very nice, but it has a midi sync problem - when monitoring the keyboard directly through Reaper, there is between 0.5 and 1.0 second delay. I've looked in the manual and cannot find a reason for this. All buffering settings concern audio, not midi, of course.

I cannot understand why there should be such a time lag with midi - maybe I'm doing something stupid, but I don't know what. Help** (This problem does not occur at all with MSI).

....this is turning out to be a saga, which I fear is only just beginning......here we go again.

Toddy,

The above statement contradicts itself.

Please confirm in your audio device properties in Reaper(you are using Reaper I assume), that you've chosen the Behringer ASIO driver.
For now , also, please make sure that you have your behringer mixer only plugged directly into the USB port on your computer.

Yes, it does. What I meant was digital to analogue from the computer works well - and the various analogue inputs also work well - to the analogue output monitor. But analogue to USB does not function well because of the poor signal to noise ratio.

Yes. But if I do that, I will have no midi to/from the computer.

Toddy,

I understand about your midi needs, how-ever I thought that if you got to a point that your system recorded and played back without crashing, that that would be a starting point.
Your mixer is considered to be good. It should also record well.

For now plug the analogues from your keyboard into your mixer and record analogue. You might not want to do that as a goal, but if you can accomplish that, it will be a significant first step. Also, the latency you mentioned while using your midi is a 'normal' characteristic, I am not saying that when your system is finally up and running that you will still have that, but that is a different 'catagory' of a problem to address. I would recommend focusing on your usb mixer only and accomplishing one step at a time.

Right. I will try what you're suggesting. I'll tell you what happened later.

This is an interesting thread where you can read about users opinions on the midi implementation of various 'daws'.

Reaper gets good grades. It seems FL Studio is a favorite with Logic being perhaps the best.

The upshot of the above (system crashes, Reaper timing errors with midi/audio, poor sound quality with Berhinger analogue audio to usb mixer) is that, after a complete Windows 7 re-installation, EVERYTHING works fine now.

But to get good quality (and indeed stereo) using the Berhinger audio to USB device, you need to specify in Windows audio device management that you are using a 2 channel input device at 44kHz or higher. The problem is, windows assumes that the USB audio input is a (mono) microphone, unless you specify otherwise.

Now that the latency problems with Reaper are sorted (using ASIO4ALL) the program is fine for midi recording - although it's not always intuitive, by any means. But support and forum activity is healthy.

Wow, congrats for keeping at it!
Good news.

Emenelton, your advice helped a lot, so thank you!
