Mapping eq positions to buttons

[r1chyb]

I am new to mixxx and working on creating a midi map for the novation launchpad and would like to map a specific value of the eq to a button. For instance pressing a button would increase the eq high by 20% and another button would increase it by 40%. I cannot seem to figure out how to do this with midi script. I am feeling rather puzzled.

The script function your button maps to would need to do the following:

1. Get the current filterHigh value and store it in a local variable, let's say 'current'
2. Assuming you want 20% of the total travel, in another local variable, call it 'increase', store 0.2 * 4.0 (the total range of the EQ knob from the MixxxControls page: http://mixxx.org/wiki/doku.php/mixxxcontrols )
3. Set filterHigh to current+increase.

If you want 20% of the remaining travel (so the increase will be smaller each time you hit the button,) store 0.2*(4.0-current) in 'increase.'

any progress on the launchpad mapping? i was thinking about writing one myself - but could skip that and do other stuff if you're working on one. i was thinking of emulating my midimasher launchpad mapping that has most controls on one page and a 2nd page with "virtual faders". not sure how useful those virtual faders are tho - certainly no use if u have a separate mixer (xsession pro, djm101 or k2 etc) but can be a solution for those with only a launchpad
