Latency sending/receiving midi from Ableton Live

Is there a way to shorten latency midi sent from and back to Ableton?  Midi I send to Midi Translator Pro and send back to Ableton lags behind other tracks in the same Ableton set.

Hi, I doubt if there is any latency within MT Pro itself but if you show your project file, I might find the reason that you would be experiencing it. MT virtual ports are very fast. Maybe you have a MIDI loop somewhere in your project setup.

 

Are you sending only back and forth from MT Pro or are you sending to a controller or synth through MT Pro and having it return data back to Ableton Live? Please also specify what control surface or application you have connected to the other end of the connection from and to Ableton Live.

Thank you for your response.  Please see the attached.  I am not using a midi controller or synth, just sending Superior Drummer kick, snare and hats from Ableton Live to MT Pro then having MT Pro transpose and send back to another midi track in Ableton.  If you are saying that it\'s highly unlikely that MT Pro would be causing any latency, there is another plugin on the Ableton Live receiving (from MT Pro) track that might be causing the latency because the original Superior Drummer track is on time, but the track receiving the midi data from MT Pro is lagging.  I will perform a test where I take off that plugin when I hear a lag to see if it\'s that plugin causing the latency.  The plugin is called instascale.

OK, I'll take a look at your project file tomorrow morning. We take reports of performance issues very seriously.

Here are my comments. I exported your project file to text and then commented within there. I also updated your project file but not preset \"Original\" because it was unchecked. Give it a try and see if it is better.

Project: 1582433109401_SD3-Split

Project MIDI IN ports:   Bome Virtual Port 1

[x] Translator 0.0: NOTE ON

Options: swallow

Incoming: Note On on ch. 1 with note:36 (0x24) and any velocity set \'qq\' to velocity, on ports Bome Virtual Port 1, Bome MIDI Translator 1 Virtual In

Rules:

 

SJC> You have preset level default input as BMT 5 and the translators within the preset as BMT 1. I suggest that you change the preset level to BMT 1 and remove the overrides at the translator level.

  SJC> You have preset level default output as BMT 9 and translators within the preset as BMT 1. I suggest you change the preset level to BMT 1 and remove the overrides at the translator level

SJC> At translator level you are sending to Both the native virtual port and its alias. This will duplicate MIDI output to the same port. Bome Virtual Port 1 is the alias and Bom MIDI Translator Virtual Port out is the real port name. 

 

 

Outgoing: Note On on ch. 2 with note:36 (0x24) and velocity:qq, to ports Bome Virtual Port 7, Bome MIDI Translator 7 Virtual Out, delay:0 seconds

 

  SJC>  Instead of delay of 0 seconds, uncheck delay

Incoming: Note On on ch. 1 with note:38 (0x26) and any velocity set \'qq\' to velocity, on ports Bome Virtual Port 1, Bome MIDI Translator 1 Virtual In

Rules:

 

  SJC> Same issues with virtual port selection. Best to stick with preset defaults unless you intend to override to something else in 1 or 2 translators. Much less work if you move things around to change a few dozen presets than potentially hundreds of individual translators.

  SJC> Here you are attempting the process the same input twice, both the alias and the real port. I think this is the crux of the delay issues.

Did this resolve your issue?

I am sorry. I am new to Bome and I think a lot of this is over my head at the moment. It may take me some time to understand this.

Take your time. I'll be here when you are ready.

Thank you Steve.
