Latency Recording External instruments

Post by kineticUk » Tue Jan 17, 2006 5:45 pm

Still got problems when recording external midi instruments
I have all the latency settings set up as described in tutorials
I have a midi clip playing my ext instrument.
Theres always a gap before the recordings if I try to record midi instruments using live.
I will use my other sequencer for now and record ext instruments using that but I have reported this since I got live 5 and would like it fixed.
I wont go on cause I have reported this enough times now and am sick of having to repeat myself 50 times for ableton to confirm they can confirm it is a problem.
Cheers

same prob here with 5.03
, i have a gap ( ~ 15ms )
even if i use the midi latency compensation and the tutorial to avoid it
it was not the case with 4.1

yep

I have the same problem and most of my studio is hardware using midi so this is a big problem for me.

abletonnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn!

Theres nothing wrong with my setup by the way so dont ask me annoying questions.

thanks.

I'm getting delay too and im trying to do the latency compensation tutorial but i'm not getting a signal from Track 2, just a low volume display and no sound. Am i doing some thing wrong?

Hi folks,

if you make an audio recording and want to have it in sync with the current running Audio/Midi you have to switch the input monitoring on your recording audio track to "off". Only if the monitoring is set to "off" the recording is compensated by the overall latency.

There could be an additionally latency based on how much time the external synth needs to "create" audio from the incoming MIDI data. But for hardware synths this value should be (normally) very low. But also this could be compensated via the "Overall Latency Compensation" value in the audio preferences.


Be careful with the latency compensation in that case. If you for example delay the MIDI track (where you send the MIDI notes to your external synth) then this delay will be present in your audio recording too.
So it is not recommended to use the delay compensation to compensate the audio recording. It is namely possible (in that case with negative delay in the MIDI track) but as soon as your play your recorded audio file it is again out of sync.



Human Koala,
there should be no difference in this behavior. If you disable the delay compensation it should behave the same like in Live 4.
Could you please check this again?


regards,
/Alex

What about resampling to another track? On my system there is a small gap before the audio.

The gap before the first beat should not be there.

Latency Fix (workround)

Post by ericbass » Wed Feb 22, 2006 8:43 am

Hi & Sorry if I'm repeating myself - I already posted this info on another thread.

I suffer with the same problem - recording the audio from external synths/drum machines, whilst playing them from a midi clip, results in a delay at the start of the new audio clip. This obviously makes a mess of sync on drums and percussion!

Same thing when recording the output of Impulse.

I've got a workround for both - they work for me, so it's not my fault if they don't work for you!!

Basically, for external stuff, you measure the delay you're getting at the start of the affected audio clips - and then enter it into the track delay box for every channel. I've simplified the process below. It's slightly different for the internal stuff like Impulse - skip to the bottom for that.

EXTERNAL SYNTHS/MODULES:-

First of all you need to measure the delay (it's different for each of the monitor modes, so stick to the AUTO setting on the midi clip and the audio clip). The delay on my system is 18ms.

1. Make a 1 bar midi clip that plays a nice clicky percussion sound on your external module - 4 beats will do.

2. Record your module's output as an audio clip.

3. Double click the audio clip and turn off warp mode in the sample display.

4. Zoom in on the start of waveform. If there's a big gap before it starts, this is what we'll measure.

5. In the sample display, under 'start' there are 3 boxes for the sample start point - click inside the third box and drag your mouse until the start marker lines up with the beginning of the sample in the display window.

6. Read the number in the box you've just been dragging in - this is your 'magic number', for want of a better term!

7. Enter your magic number into the track delay box in the mixer section. Do this before you record into a slot.

8. Make sure that Delay Compensation is enabled on the Options menu (it makes a difference - don't know why).

9. Record your track.

10. You should find that the gaps at the start of the audio have gone AND that midi and audio play in perfect sync.

11. NOTE - it might sound out of sync during recording, but don't worry - it will be ok on playback.

12. Enter that magic number for EVERY channel (although it doesn't seem to affect midi going out to external gear).

13. Sorted!


RECORDING THE OUTPUT OF IMPULSE/SIMPLER:

1. You will be happilly playing along now, with your magic number entered on each track...

2. But, to record the Impulse/Simpler to an audio track...

3. Set the Track Delay to zero for both the midi track AND the audio track!

4. When you finish recording, set the track delay to what it was beforehand.

5. Job done!

Don't forget to set the track delay to zero if you render a file to disk that you want to re-use in your project, or you'll end up with a gap on the start of that as well.


Hope this helps some of you - it was giving me a bad headache.

Ableton tech-people - please fix it! It should do all this stuff by itself!!!!


Happy regards
