I'm using the IDD with Mixxx 2.1 alpha pre and the default mappings (by Rik Prokup, I believe) which come with Mixxx 2.1 alpha. The IDD mostly works. Thanks for that! But, hitting the IDD "scratch\Search" toggle button throws an error: "Uncaught exception at line 1 in passed code: TypeError: Result Of Expression '(IonDiscoverDJ.toggle_scratch_mode_off)' [undefined] is not a function." Does anyone know how to fix it? Thanks!

Thank you for reporting the issue. It looks like that missing IonDiscoverDJ.toggle_scratch_mode_off is not actually needed. Please try using the attached mapping files. If it fixes the issue we'll update the mapping included in Mixxx.

Thanks for your amazing quick reply and fix! With your updated mappings, the "scratch/search" toggle seems to function as expected: in scratch mode, touching the platter stops the playback and spinning the platter allows precise positioning within the track. In search mode, touching the platter does not stop the track and spinning the platter allows start-to-end positioning in the track. The toggle seems to work, with one quirk: it seems as if I have to hit the toggle twice to change modes. That's no big deal, though! Thanks so much! This community is amazing!

Does this mapping fix that issue?

Is there a recommended method to adjust the sensitivity of the scratch wheels on the IDD? I ask because the wheels seem to be so sensitive that if I'm heavy scratching on a track playing on deck 2, with a track paused on deck 1, just the vibrations of the IDD can cause the track on deck 1 to scratch, also. I do have the IDD set up on a somewhat wobbly folding table, so it may just be my issue and I need a sturdier table. Thanks. :)

The fix has been committed, so the scratch button should be fixed in new master builds.

You'd have to adjust the scaling of the MIDI messages in the script's IonDiscoverDJ.Deck.prototype.jogMove function.
