    I cannot reproduce this unfortunately. You are on Windows I suppose. What are the exact steps you do?

    I do:

    1. New project
    2. Add track with ReaLearn as input FX
    3. Add mapping
    4. Edit
    5. Target => Learn
    6. Move volume slider of that track
    7. Target is assigned as expected

    This is happening to me too.

    Im on Windows 10 64x, running Reaper 64x. Reaper 5.7

    My project is relatively large (41 tracks), designed for live use, with two audio inputs (mic and guitar), and various midi devices (FCB1010 foot controller, nanoKontrol II, Akai keyboard, Alesis PercPed). I use SWS live configs to switch between routings and tracks so I have hands free preset swithching with my FCB1010 - for preset switching I dont use ReaLearn, I just program my FCB1010 to send CC messages.

    I am using ReaLearn with the nanoKontrol to control various parameters on different tracks. I have one track that is only for my nanoKontrol II, its sole purpose is to host ReaLearn on its dedicated midi channel. On the input FX i have, so far, 3 instances of ReaLearn (so its easy to manage the various mappings).

    My problems started when I started trying to map more things with the nanoKontrol. The crash is always the same. Its when I ask ReaLearn to learn target mapping. I click it and it goes into "learn" mode no problem, then I go to the VST in the track which I want to control and move a parameter of the VST. I can click and drag it, but once I let go, it freezes and then crashes. (showing some of the routings I have set up) (showing how a mapping works on an existing instance of Realearn but not on a new one)

    It happens on all VSTs and even on a Reaper fader.

    At first the crash happened with only one instance of ReaLearn, then I updated to latest version and it seems to be fixed. Since the crash reappeared, it only seems to happen on new instances of ReaLearn. On the nanoKontrol track I have 3 instances that work and can assign new mappings (although it has crashed occasionally...but then it works after restarting it), now on my 4th instance, I can not make any new mappings without crashing it.

    Thing is, with some VSTs I can't even assign the mapping manually because the parameters dont seem to list in the editing menu in Realearn, as a temporary workaround I could just load up the instance of Realearn that actually works but this will get confusing when I need to make a change.

    Could reproduce it, especially when MIDI feedback enabled. I have also fixed similar potential crash causes. Will be in upcoming release (1.2.0).
