Feature Request: selectable MIDI range filter/map #29

Open lrfinotti opened 3 years ago

lrfinotti commented 3 years ago

I was wondering if it would be possible to tweak the interface/functionality of either MIDI note/channel map or MIDI key-range filter.

Here is my situation: I have a MIDI drum track and I want to send certain MIDI notes to different samplers. Currently I have to set a few MIDI key-range filters to have only the notes I want/need.

I would be nice if I could just toggle which notes (in a chosen octave) I want to pass through the filter. (Maybe shift clicking to select a range. An invert selection button would also be convenient.) I might, for instance, want to let C2 pass, but not C3.

Alternatively, I could use the note/channel map to select a different channel for each of the samples. In this case, the note selection currently does not allow me to distinguish between different octaves, which makes it hard to use, as most drum kits have more than one octave.

(And thanks for all your work!)

This is an old issue, but could you do what you are looking for with https://github.com/x42/midimap.lv2. I'm not certain what you are trying to accomplish or I'd suggest a configuration. You could map certain notes to different channels (for different samplers) using a single midimap after the drum track or only allow certain notes to pass which will probably require multiple midimaps, one in front of each sampler. Anyhow, just an idea if you are still looking for a solution.
