and now .. 3 fx mute and solo
the recarms mutes the items on the track leaving the fx on the track as they are
the muting is sweitched at once, but the reaper reacts a liitle later, has something to do with buffers..
this creates weird stuff
but i works

HOW TO

make a portable installation (put your reaperlicense into that portable folder) and
import the config file in the portable installation

running this should open the template

'the midimix has to be the first mididevice

all sliders and knobs should be down btw. left

hit BANK LEFT (cursor to the beginning) and BANK RIGHT (start playing)

the demoproject has explicit stuff in it as it is sampled from this deadmau5 video

drag sliders
wiggle knobs
mute and solo

press reacarm buttons and listen to wonderful noises left when audio mutes on the track

the routing and the assigned actions are matched to exactly this project
there are some tracks that aren't used
for own projects you have to check the midi assignments for the actions and edit the recarm scripts .

Best practice for new own projects would be to focus on one track (though make 8 tracks to start isn't the worst idea)
make a head about signal routing
apply a working signal routing
make the assignments to the knobs
edit the recarm scripts as needed

and have fun
and remember : If you are not a daw pro after learning -beep- reaper then, you know, there's something wrong with you"
