So I'm trying to modulate some sample parameters such that every time I hit a MIDI note, the current value of parameters modulated by the LFO is frozen. I want different values on notes but don't want the values moving while the note is held.

This is similar to the functionality of Elektron boxes, where setting the LFO to "HOLD" will simply hold the current value when the note is on, while the LFO itself continues running in the background. I want to maintain the periodic nature of a sine or saw wave, so I'm not looking for a S&H wave either.

Currently, I have two velocity devices and an expression control with the LFO. Velocity 1 simply sets the velocity incoming to 127. Velocity 2 has a low out of 1, and the high out is modulated by the LFO.

Then, expression control is set to Velocity, and it modulates the parameter.

You can see how this holds the current value, because expression control only gets a Velocity input on note on, so the LFO moving the velocity doesn't effect the parameter. But there must be an easier way! In this method, I also have to put the sample or instrument in another chain so I can still use note velocities. It's super annoying.

Please help!

Not a general latency question!

My current use case is with an iPad, using AudioPipelineReceive. I have a MIDI track with an instrument loaded, usually a drum rack, or simply a little loop of audio.
I pick up that audio on my iPad in AUM or Loopy Pro using the AUv3 AudioPipelineReceive. The app reports latency to Ableton. Then I route that audio into another instance of AudioPipeline, which send the audio back into ableton.

I make a new audio track, have it receive audio from the Link Audio peer that is my AudioPipeline instance, and can receive audio.

Here’s the problem: I have the Link Audio latency down to 9.28 ms, buffer size at 32. Host on iPad also on 32 buffer. I can get the audio down to about 9 ms latency once received. However, none of the normal syncing tricks I use in Ableton will work to line that up perfect.

External effect doesn’t work, since audio is being picked up by the AudioPipeline outside of the signal flow of the sending track. Usually with an external synth I’d use separate midi and audio tracks and use track delay to compensate. Driver error compensation doesn’t do anything since it’s processed out of the loop of the main audio driver. Doesn’t seem like there’s a way for the track to compensate for the latency introduced by this process. Except manually nudging, which is not really a solution.

I have “sync to incoming audio” turned off, by the way, as that makes the latency worse.

MacBook Pro with M3 Max, Ableton 12.4.something, not the latest Beta but the one before.

Any insights from the community? I know it’s a niche issue but it would be great to have a better way to manage this latency better, as it seems like it falls outside the purview of current tools. Thanks!
