Script for Random Round Robins position w/ two microphones

Babble · 2022-07-18T19:27:23+00:00

There was an error rendering this rich post.

Infant scripting child here, so please be gentle. I'm trying to accomplish something fairly simple, which involves keeping my first five groups (1-5 (mic A)) , and my second set of five groups (6-10 (mic B)) together via their respective round robin position (ie RR position 1 is used for groups 1 & 6, RR position 2 is used for 2 & 7) but using code so that they cycle randomly while not repeating the last sample just played. David Hilowitz had posted a video on this subject, and I've read through some of the other threads, but I still can't find a method that works given the constraints.

on init

make_perfview

set_ui_height_px(255)

set_ui_width_px(633)

declare $mouse_resp := -900

set_control_par_str($INST_WALLPAPER_ID,$CONTROL_PAR_PICTURE,"instrumentbackground")

declare ui_slider $NEAR(0,1000000)

make_persistent($NEAR)

declare $k_NEAR

$k_NEAR := get_ui_id($NEAR)

set_control_par_str($k_NEAR,$CONTROL_PAR_PICTURE,"MK2-64")

set_control_par($k_NEAR,$CONTROL_PAR_POS_X,25)

set_control_par($k_NEAR,$CONTROL_PAR_POS_Y,80)

set_control_par($k_NEAR,$CONTROL_PAR_MOUSE_BEHAVIOUR,$mouse_resp)

declare ui_slider $Far(0,1000000)

make_persistent($Far)

declare $k_Far

$k_Far := get_ui_id($Far)

set_control_par_str($k_Far,$CONTROL_PAR_PICTURE,"MK2-64")

set_control_par($k_Far,$CONTROL_PAR_POS_X,110)

set_control_par($k_Far,$CONTROL_PAR_POS_Y,80)

set_control_par($k_Far,$CONTROL_PAR_MOUSE_BEHAVIOUR,$mouse_resp)

declare %rr_index[10] := (0,1,2,3,4,5,6,7,8,9) {not sure num is needed}

declare %rr_index_prev[10] := (0,1,2,3,4,5,6,7,8,9) {this may be incorrect}

end on

on ui_control($NEAR)

set_engine_par($ENGINE_PAR_VOLUME, $NEAR, -1, -1, $NI_BUS_OFFSET + 0)

end on

on ui_control($Far)

set_engine_par($ENGINE_PAR_VOLUME, $Far, -1, -1, $NI_BUS_OFFSET + 1)

end on

on note

if (rr_random = 0) {I get an error here saying ) expected}

%rr_index[$EVENT_NOTE] := %rr_index[$EVENT_NOTE] + 1

if %rr_index[$EVENT_NOTE] >= $MAX_RR

%rr_index[$EVENT_NOTE] := 0

end if

else

%rr_index_prev[$EVENT_NOTE] := %rr_index[$EVENT_NOTE]

while %rr_index[$EVENT_NOTE] = %rr_index_prev[$EVENT_NOTE]

%rr_index[$EVENT_NOTE] := random(0, $MAX_RR-1)

end while

end if

disallow_group($ALL_GROUPS)

allow_group(%rr_index[$EVENT_NOTE]) { Close? }

allow_group(%rr_index[$EVENT_NOTE] + 10) { Far? }

message("note -> " & $EVENT_NOTE & " / vel = " & $EVENT_VELOCITY & " / rr = " & rr_index[$EVENT_NOTE])

end on

Please read the sticky about how to post code around here. 😊

As to your question - you're going in the right direction, but you probably need to just do + 5 instead of + 10 in that second allow_group(), if you have 5 RR groups per mic.

Hey Babble - code noob here as well. I was adapting your code to fit my situation and I got the error in the same spot you pointed yours out. Did you ever solve the error in that line and if so could you share the solution with me? Thank you!

Not sure about this, but in the on note callback, where is rr_random coming from? It doesn't look like it's been declared anywhere

Good catch - I declared it but wasn't sure what value to give it. In my case I want 4 round robins so I put 4. The code didn't get any errors, but when I press a note it takes a good half second to crunch some huge array before outputting a note (and every output resulted in rr0). While it was processing the array I saw a message at the very bottom of the Kontakt window saying something about the array being out of bounds or something.

You probably need to assign it a random value if you want random RRs. So use this plus the range of RRs you have to give it a value. Maybe?

Thank you so much for jumping in to help Jared. This morning I managed to achieve my desired result by using a different code resource I had found and combining it with Babble's idea to add a second "allow group" line with "+4". Worked like a charm - it now randomizes groups 1-4 and triggers the respective group 5-8 alongside it. Beautiful.

I wanted to share how my code ended up looking, but every time I click "post comment" it does nothing (code is properly formatted too). If I can get it to work I'll share it here!

Trying again - here's what my code ended up looking like:

on init
declare %list[4]	
declare $at := num_elements(%list)	
declare $x	
declare $last	
end on

on note
disallow_group($ALL_GROUPS)	
inc($at)	
if($at >= num_elements(%list))	
$last := %list[num_elements(%list) - 1]	
%list[0] := 0	
$at := 1	
 while($at # num_elements(%list))	
 $x := random(0, $at)	
 %list[$at] := %list[$x]	
 %list[$x] := $at	
 inc($at)	
 end while	
$at := 0	
 if(%list[0] = $last)	
 %list[0] := %list[num_elements(%list) - 1]	
 %list[num_elements(%list) - 1] := $last	
 end if	
end if	
allow_group(%list[$at])	
allow_group(%list[$at]+4)	

end on
