USAMO and 'audio' jitter

Author USAMO and 'audio' jitter
alex5276
I have 3 usamo devices sending midi notes to my synths. The setup is very simple....

- Using Ableton and direct monitoring via TotalMix Loopback giving me approx 144 samples latency all the time.

- i use the latency fixer from ES to compensate the synthesizers extra latency. I have one latency fixer on each of the Midi track with the USAMO plugin.

- I record audio with Monitor set to 'off' all the time.

When i record the audio from the midi notes played via the USAMO, the audio is not always bang on the grid. Slightly before and slightly after. We are talking less than 1ms but still, how can i get this to be on the grid all the time ?

Hopefully someone can help....

It's quite possible that the remaining jitter is down to your synths' response to MIDI.
alex5276
OK, thank you for your response !
Shledge
If it's less than 1ms, then I wouldn't worry about it. It's practically imperceptible.
alex5276
Is it possible that the jitter comes from the KENTON Pro MKii ?

I have USAMO --> Kenton pro mk2 --> SH101
os
It's possible. That, and/or the SH101's MIDI input.

You'd be better off driving the SH101 with CVs directly generated in software (e.g. via Silent Way).
alex5276
I cant find the ES-4 anywhere to buy, is there any reason ?

I am interested in connecting SPDIF and replace the kenton with the ES4 that would solve my problem.
os
The ES-4 was replaced by the ES-40.
alex5276
Ah, okay thanks.

I managed to get a ES4 this evening. However the plugin doesnt show up in my Ableton Live 10. Any idea what's going on ?
alex5276
I put both the VST and the AU plugins in their respective folders (VST and Components)...
alex5276
ignore me its fine...
alex5276
Sorry for posting so many messages but here is my last question !

I have a pro one and a sh 101.

I want to use the ES-4 to control both synthesizers but as you know we cant change the channel on those synth.

How can i control both on Ableton ?
They will need two different calibration.

edit:

I assume in the plugin i will be able to choose the output of each cv out. Do i just need to put two plugins (similar to usamo) ?
os
If you're controlling them by CV from the ES-4 Controller, you just need one plug-in, and make use of the two MIDI/CV sections in there.
alex5276
OK noted. But in that case how would you compensate with the record latency of the two different synthesizers ?

With the USAMO, i have two different plugins setup with two 'Latency Fixer' to adjust the audio to be on the grid.
os
You could shift the MIDI itself going into the plug-in.

Or you could try using two plug-ins, with a Latency Fixer in between. The one has to feed into the other though - you can't just put them on two tracks both outputting to the SPDIF.
alex5276
Mmm i am not sure i understand....

1) So i create a Midi track and put the ES4-Controller plugin.
2) I set the ext out to 9/10 (SPDIF)
3) I check that the first synth works (Out 1 and gate 3)
4) i put a latency fixer and adjust hardware audio delay

That's for sh101..Then for Pro One

5) on the same Midi track i put another ES4-Controller plugin to control (out 2 and gate 4), as a chain ?
6) then followed by another Latency fixer ?
7) which would allow me to adjust the pro one hardware audio delay ?

Do you have a screen shot by any chance on Ableton ?

Thanks for the help !

Obviously this is an example here..... I didnt set up the ext.out to SPDIF yet.
os
Something like that. Honestly, I've never considered this before. You'll need to experiment.
alex5276
All fine.
alex5276
Hi i managed to play with the devices and i am playing my two synths separately. All good.

However it appears i cant go down very much in the octaves. How do i adjust this ?

Edit: when i play C3 on my midi keyboard it plays a C2 on my synthesizer. I did the calibration via the HW ES-4 calibration (not the V/Oct one).
alex5276
Here is a screenshot of my setup.

Basically when i play i C2 on my midi keyboard, it plays a C0 on my Pro One.

My Pro One is correctly tuned.

edit: I played with the 'Min' for each of the Midi 1 and Midi 2 until it is in tune. Is that the correct procedure ? However now my midi keyboard doesnt track the synthesizer. For example i play a C3 on my Midi keyboard it plays a C on my synth but i need to change the range on the synthesizer (0, 1, 2, 3) to get another C. It doesnt work the same as with the Kenton Pro....

Hey guys just got my USAMO. Trying to purchase a licence for it. I don't see it in your list of products in your store. Please advise.
Thx, Chris
