U-SYNC: sending MIDI Notes on time
Right now U-SYNC, and generally the Nome, is only used for MIDI Clock and MIDI Start/Stop.
You can send MIDI Notes to your machines either directly from your DAW or through the Nome using the MIDI Forwarding feature.
But that feature simply "forwards" the MIDI Data received, at the time it was received. In other words, it does not do anything to improve the timing of the MIDI messages sent by the DAW, which can be terrible and not in time at all with the U-SYNC timing.
For sequencers that's not a problem because the note sequence is usually in the sequencer and can be triggered with a MIDI Start message, sent perfectly on time by the Nome. But it's an issue for arpeggiators, or simply synths you want to "play" directly from MIDI Notes in your DAW.
So, with that in mind, the idea is to add the possibility for U-SYNC to send MIDI Notes as well, perfectly on time with the clock timing.
Any thoughts?

PS: there has been quite a few discussions about this, in particular @asender on this topic but also @dheeraj found a workaround using Ableton's tempo follower in that topic.

Re: U-SYNC: sending MIDI Notes on time
I would love to have this feature in Nome II as I have issues from time to time to get my recorded MIDI-Events in Logic in time to my analog synths and back recorded in time! It`s annoying to shift the recorded regions by hand to be right... One time the recorded audio was even before the first note (maybe happened because of Logics latency compensation).
Furthermore when a DAW-project is more filled with plugins causing latency the problem gets worse. I don´t know: is it possible that U-SYNC could also help in that case or is this a "natural" latency problem that can't be improved?

Re: U-SYNC: sending MIDI Notes on time
Thanks for your thoughts Manu!
Plugin latency should not affect this as it should be compensated by PDC (Plugin Delay Compensation) in your DAW. Check your settings
(in fact the U-SYNC plugin, in order to be able to send things on time, adds also a bit (7ms) of Plugin latency)

One million +1’s for this feature.

Re: U-SYNC: sending MIDI Notes on time
This has been asked quite a bit recently. I've boosted the timeline for this feature and it is now officially included in the U-SYNC 2.0 roadmap.

Re: U-SYNC: sending MIDI Notes on time
Would need this before buying as two of my synths are midi over DIN only. Need clock and midi notes on the same cable.

Re: U-SYNC: sending MIDI Notes on time
You can still send notes and clock over DIN-MIDI with the Nome. The only thing this feature add is better timing for the MIDI notes (as its title says). With the current version they have the "usual" timing, i.e. the same timing you would get without the Nome.producer_steve wrote: ↑25 Jul 2025, 19:17 Would need this before buying as two of my synths are midi over DIN only.

Re: U-SYNC: sending MIDI Notes on time
FWIW, just got a MacBook Air M4 runing masOS 26 Tahoe, and configured U-SYNC to use with my Midronome and Cubase 14, whom MIDI Note timing is actually very very sharp out of the box thanks to Core Audio. MIDI Clock not so much, but that's common behaviour on many DAW.
Tested with the MidiGAL, a good old AMT-8, and an UMC404HD audio interface.
https://midisizer.com/midigal/midiclock-tester/
I'm running 4 bars of MIDI Clock, then 1/4, 1/8, 1/16 and 1/32th notes (clock disabled if possible), at 120BPM then 175BPM.
When introducing the Midronome in the system, bi-directionnal works like a charm, and it sharpens the MIDI Clock as expected from ~0,222% deviation over the median to a mindblowing 0.004% at 120BPM (0.333% vs 0.006% at 175BPM).
But it kinda messes the Note On timing compared to Cubase alone, especially at the beginning of the bar when looping.
I think combining MIDI Clock and MIDI Note into Cubase (or any other DAW) messes the later a bit already, even without the Midronome.
Have to investigate more.
Still, overall figures on macOS are still very very good. Best MIDI timing I've ever got on any computer so far.
Especially without specialised hardware & software combination like Steinberg's LTB or Emagic's AMT back in the days.
Which leads me to a question: how would you fix the timing of MIDI Notes sent too late by the computer or any MIDI device, without timestamping and buffering of the events into the Nome?

Re: U-SYNC: sending MIDI Notes on time
Thanks for the analysis, that is very nice to know!
Let's see - I have not even started development on this. FW 5.0 first

The same way it works with the clock, the U-SYNC plugin has the knowledge of which note is where (for this it will need to receive the MIDI Notes somehow). Then it simply passes that information to the Nome who then "plays" the notes where they are supposed to be (based on the clock's timing).
