Could you let me > know so I can see if it's something the Mk2 should be doing too. > So, I was trying to emulate CDJ behaviour where by if you hold CUE the music starts to play, if you release CUE the song position returns to the CUE point, however if you hold CUE and then hit PLAY (CUE+PLAY) before releasing CUE the song goes into normal playback mode preventing the release of CUE from repositioning the song. The Javascript code I wrote seems like it ends up fighting the playback engine in some kind of race (which is why it trys to do get position, stop, reposition, play really quickly)... It only works something like one 5th the time for me on the RMX. This was something we originally talked about doing inside the playback engine, but I thought it would be interesting to see if it was possible doing it via javascript. > Headphone selection - The device has the following settings: Deck A/Deck > B/Mix/Split.

Alternatively, for Split could do it Deck1 in Left, Deck 2 in Right... I'm not really sure it's doable to manipulate the channels in the headphones like that within Mixxx, though I haven't spent much time on it.

Should I just get on and do it? > Right, so I would be in support of changing into Loop/Cue/Fx as you described. The mappings (see mixxx.org/hercules/) are defined to 1,2,3 kill hi, mid, lo, and mode arrow is reverse. The reason the mappings are as they currently are is, that until Mixxx 1.7, we had no way to dynamically remap functions via modes (all controllers were stateless from Mixxx's perspective) and we also lacked the ability to easily redefine the behaviours. > The attached are a pretty good starting point (for scripting the Mk2) > anyhow I'd say.

In the mean time, I want to encourage other Herc Mk2 users on the list to grab them and offer feed back. At the moment, I think only yourself and Siarhei are into the Mk2 scripting, but Robin and others may also be interested as we should try to keep the behaviour of the Mk2 as consistent the the MP3 control as possible. Anyway, keep plugging at it... this is good. :D Cheers, -G
