Filter, Route & Trigger


The Midi Filter pack is a selection of tools for filtering, routing and triggering with midi notes. You can break out of the limitation of Live’s transport and trigger multiple tracks from a played beat or melody.Every nth C3 note could play a chord or note from a set sequence and/or trigger a parameter change anywhere in your set. Each device has its own unique ID which means midi notes can be routed from any other device in the Set, and routing can be made from any point in the chain.

MF Skipper- Play only the first x number of notes from each selected number of notes passing through the device. You can also select the starting note allowed through. You can use this to quickly filter midi routed from another track so that only the first note will get through and trigger a chord or other element. You can also set the device to reset at the beginning of a playing clip. Like most of the devices, you can also set the midi passed through to trigger a parameter change, and allow the actual midi notes to pass through the device unfiltered if needed.

MF NoteRange – This device will filter the midi notes based on the pitch. It can be set to allow or block a specific range of midi values or a single value. Again this could be used to simply trigger a parameter change using a specific note or range of notes.

MF Velocity – This works exactly as the NoteRange device, only the filtering is done from the velocity of the incoming notes. Again the device can either allow through or block a set range of values, or single value.

MF NoRepeat – This device will simply block any note if the previous note had the same value. In the image you can see the input selection, as any device can take its input from any other device in the set. So this device’s ouput can still be used as a source for other devices, even when the midi is actually passed through the chain unfiltered.

MF Doubler – This device will trigger a second note from the note off message. The note length can be set, and velocity can be set relative to the original note.

MF Following – This will only allow through a single midi note which follows a specific sequence of notes. The sequence can be from 1 – 3 notes length. In the above example, if E3 then B3 then G3 come through then the next note will pass through the device. This can be very useful if the number of notes might change within any sequence, but perhaps the 4th bar will finish differently, so that can be an indicator of the first note of the next sequence. The sequence of notes used to trigger can also be recorded directly into the device instead of using the knobs.

MF Note – This device will filter according to the notes set on the display. Of course this could also be done with Live’s Scale midi effect, but the UI here is much more intuitive and quick to use. The device also has the parameter triggering options as the other devices.

MF Phraser – Record in a sequence of midi notes of any length. The device will now play through that sequence using the input to trigger each note. Either any midi note input will trigger the play or one specific note trigger can be set. The output can also be transposed.

MF Span – This is one device that actually uses Live’s transport, and will open and close the gate based on a proportion of a sequence length in beats. Changing the slider to open the gate for different lengths of time on the fly can make for some easy live note filtering. This one can also be set to reset on the beginning of a looped clip.

MF Allpass – This device can be placed at the beginning of any midi effect chain. It does not filter or trigger anything itself. Its ouput can then be used as input in any of the other devices anywhere in your set. This makes the routing and filtering very flexible and allowing for multiple paths of routing in any chain, without needing to route midi to many different tracks and using multiple versions of the same device in each track.

MF Paramaster – Incoming midi notes are used to trigger increments in parameter changes. The number of notes used to go through the whole sequence is set with the number box. The device can go forwards and loop or it can be set to palindrome mode where once the maximum is reached it will go in reverse and loop like that.


Any device which modifies the midi has this section which can be edited by pressing the I/O button.

The dropdown menu will select the input routing for the device. 0 MIDI will work with the normal midi notes coming through to the device in that Track’s chain. Any other MF device has a unique ID and routing path so can be selected as input. This means that midi can be routed from any point in any chain of midi effects in any place in the Live Set.

Under this is the parameter trigger section. Click Map and then select any parameter in the Live Set for modulation. There is a simple AD envelope including curve selection (by moving up or down with the mouse) and a range slider to control what range of the entire parameter is changed. Hold shift and drag to change only the top or bottom of the slider range.

MIDI Thru can be used to bypass the MIDI routing of the device, in which case it can be used only to create parameter changes without affecting the MIDI notes.

Our Products are generally provided as Zip file downloads which in all cases will need to be extracted and saved to your hard drive prior to installation. Details on the different file type provided and what to do with them are below.

.alp Files – These are Ableton Live Packs and will install directly into the Packs Section of the browser of Ableton Live. When you double click on them you will see a pop up window asking you to confirm that installation is ok as the files are described as “Legacy”. This is fine and you are ok to proceed, the packs are created using the format for an earlier version of Live and so remain compatible with the current version.

.amxd files – These are individual MaxforLive Devices and can be stored anywhere on your hard drive. We’d advise creating a folder for them and then adding that folder as a location within the Places section of Lives Browser.

Control Surface Scripts – Please refer to the individual User Guides provided with your download, an abridged version of the installation will be shown further down this page.

ClyphX Pro – Please refer directly to the manual and installation video for this specific product.

Novation Circuit Packs – These are provided as individual Sysex Files and as a complete bank file. All are to be installed using a version of the Circuit Editor and not via Novations Components back up utility.


LDM Devices

LDM Design is a project which started life in 2016, recreating Monome apps in Max For Live to use natively on the Launchpad Mini, which are still freely available on his website.He also created the popular glitchy multi-FX sequencer devices Manglerack and MangleFX, influenced by the legendary Illformed Glitch VST. Since then the project has expanded into making all kinds of M4L devices, always taking care in designing a clean, unique GUI.Many of his devices also show a love for introducing various degrees of chaos and probability into music production. His first release for Isotonik, the LP Pack, continued recreating and improving upon classic Monome apps and original ideas to expand the creative potential of the Novation Launchpad Mk1 and Mk2. Next, as a homage to the great Brian Eno and his creative processes, LDM then released the best-selling Chance 10 Pack, which is a selection of modules utilizing chaos and probability to affect various elements of production. There are a number of great free devices available on his website – Chords in Key converts single MIDI notes into chords based on a set key, Gravity Delay is a fun ‘bouncing ball’ MIDI delay, and Autosputter is for live glitchy audio slicing, based on the old Instajungle VST.LDM Design continues to work on projects for Isotonik and his own website which will be available soon.
