Hi Everyone!

I've just bought MIR and I enjoy it very much! It sounds great and has a very friendly user interface!

Now, as it's back to audio transfer between my master DAW PC and the slave MIR it's somehow a step back in my production process.

I'm now experiencing what I've forgot with VE pro = latency between my DAW and the MIR. With 256 ms on both computer it seems impossible to sync the tempo click between them. Say I want to add a drum part on my master DAW it will be way ahead of the orchestra.

Any idea how I can compensate this? It feels odd since I kind of already asked these questions when I was using Gigastudio :)

Back to the future when MIR pro will come out I guess!!!

Thx!

Hi Ramu,

thanks for the friendly comments!

A rough estimation of MIR`s latency is very obvious: The latency reported by the ASIO-driver, multiplied by the number of buffers set in the Audio Settings (... a buffer-setting of 1 actually means "One additional buffer", so it`s two time the latency ... the details are in the manual).

_Measuring_ the latency of a signal going through MIR compared with another signal-flow outside MIR is easy, too:

- Load a very clear percussive instrument, like a woodblock, both into MIR and into a VI outside MIR.

- Use the same MIDI-signal to trigger both at the same time (... make sure MIR is set to "Direct Only")

- Record the resulting signals in a DAW and measure the distance between both signals. The offset is the amount you will havee to shift one of the signals for getting them in sync again.

HTH,

Hi Dietz,

Thanks for these answers!

This is quite what I'm doing now :)

It's just I was hoping someone (I guess at steinberg as I'm using cubase) had known about a secret feature that would allow midi entries to be played a head of there actual position (meaning that graphically there is no change but it would be launched ahead of a value the user could enter...it's wonderful to dream isn't it?)

I'm now flying over earth with MIR! Thank you SO much for this incredible tool!

Now i dont have MIR, but if i understand your question right, this can be done very quickly in Cubase, altho you have to do it for each midi\audio track.

In the leftside inspector panel for each track, you can offset a negative or positive value specified in MS`s to each track, so the playback will be offset accordingly without moving the sequencer data. This requires that you know how much you need to offset in MS`s offcourse.

in Old versions of Cubase, you used to be able to do this individualy for each midi part, which was a very good feature so that you could adjust the timing of each part independantly.

But this should work for your needs i think?
