MIDI CHannel Filter

Post by slothmusik » Sat Sep 27, 2025 1:19 pm

Hi all

I'm running Ableton Live 10, and am looking for a MIDI channel filter. Not an audio device, but MIDI. All I want to do is pass MIDI data from a specific device, and on a specific channel, to the MIDI In of another VST. Sorry if that's not clear, but it's early ...

Sometimes plugins have bitimbral features which allow them to receive midi on individual channels to trigger individual sounds.

The bitrimbal aspect of these is not usually the most straightforward to connect to in Live. The main channel that is Hosting the plugin has limited ‘filtering’ options. The best way to go Directly to a plugin within a channel (whether it be an instrument or an fx device) is to create another midi channel that receives from your preferred device but more importantly is routed to your plugin’s channel. There will be more options for which plugin to route to and which channel of the plugin to send midi to.

I've probably not been as specific as i need to be here, and thanks for the responses to date!

Here's what i am trying to set up.

I am using an instance of Intermorphic's Wotja. It is treated in Live as an instrument, not an effect. It provides 16 MIDI channels of generative data. Wotja is available as a standalone, and as a VST3. I am trying to use the VST3 version in this application.

I am then trying to filter Wotja output such that only one channel of MIDI data is passed to each subsequent MIDI track in Live. If it is to work at all, it seems to me that I need some sort of MIDI filter that will pass one channel only of data to a designated VST.

I can't seem to make this work, and maybe it can't?

Any thoughts here?

PS - in the past, i've just used the standalone version of Wotja plus loopMIDI to accomplish this. I wanted to try the VST3 in the interest of tightening up sync.

I was able to circumvent this limitation in only one way: I place the required VST3 inside a Plogue Bidule, then use a channel filter to split the MIDI signal into 16 channels and feed it to 16 different OSC output devices in this Bidule, and feed the signals to 16 tracks with Bidule instances with OSC input devices. Overhead: each Bidule instance is ~5 kB, and MIDI transmission latency via OSC is ~2 ms. (For LoopMIDI, it's ~8 ms.)

Hey Valkon

I had forgotten about Bidule ... good one!
Thanks for the share!

Hi, I've the same problem with Battalion from Unfiltered Audio.

I started a thread about it here:
viewtopic.php?t=252861

I haven't been able to control the transport of the instrument's own sequencer with MIDI notes on channel 10, as described in the phantasy manual.

I use 2 MIDI channels for this and connect them to channel 10. It doesn't work. Tools such as loopMIDI don't work either. The notes are either sent on all channels or not at all. The transport control of the Battalion sequencer cannot be accomplished with MIDI notes from the DAW.

It may also be that the implementation in Battalion is faulty. I have no idea. I have already inquired with unfiltered audio, but they don't respond anymore these days. If a reasonable MIDI export of the sequencer data were possible, it would be bearable—but that's not even built in. Others manage to do it, e.g. Sugar Bytes in their drum computer.

So in Battalion, you can only use the DAW's sequencer, which can only control notes and velocity. Or you can let the sequencer run the whole time. What nonsense. Some people then resample audio files and cut them. But that's technically a joke. I have a built-in sequencer with humanize and swing, but I can only program one pattern and can't export anything. That's bullshit.
