Help with String:replace

[dasfaker]

I’m trying to copy the sysex formula of a modulator to a string and manipulate some bytes, so I’m doing this:

syxFormula = mod:getMidiMessage(0):getPropertyString("midiMessageSysExFormula")
if syxFormula:contains("k0") == true then
     syxFormula1 = syxFormula:replace("k0",tostring(panel:getModulatorByName("GLOBAL Part"):getValue()),false)
     end
if syxFormula1:contains("k1") == true then
     syxFormula2 = syxFormula1:replace("k1",tostring(panel:getModulatorByName("GLOBAL Tone"):getValue()),false)
     end

syxFormula is a String (Juce string?) but syxFormula1 is a string(lua string?), so I cannot use replace with syxFormula1. How can I convert this string into a String?

I’ve done this longtime ago and worked

mp1mid1 = panel:getModulatorByName("PartSamplNb-1"):getMidiMessage()
mp1mid2 = panel:getModulatorByName("Volume-1"):getMidiMessage()
mp1mid3 = panel:getModulatorByName("Pan-1"):getMidiMessage()
p1m1 =(string.format("%s %s %s",prfix1,map1val[newValue+1],sufix1)) 
p1m2 =(string.format("%s %s %s %s",prfix1,map1val[newValue+1],mpbyt2,sufix2))
p1m3 =(string.format("%s %s %s %s",prfix1,map1val[newValue+1],mpbyt3,sufix2))
 prfix1 = "f0 41 10 00 1d 12 12 00" 
 sufix1 = "00 MS LS z6 f7"
 sufix2 = "xx z5 f7"
map1val ={"00","01","02","03","04","05","06","07","08","09","0a","0b"}
 mpbyt2 = "02"
 mpbyt3 = "03"  pbyt2 = "04"  
mp1mid1:setProperty("midiMessageSysExFormula",(p1m1),false)
mp1mid2:setProperty("midiMessageSysExFormula",(p1m2),false)
mp1mid3:setProperty("midiMessageSysExFormula",(p1m3),false)

getMidiMessage() is wrong now ,I notice you enter a 0 in it why ?

Did you try string.gsub(syxFormula,”k0″,””..panel:getModulatorByName(“GLOBAL Part”):getValue()) ?

Because otherwise it doesn’t work for me. With this 0 I get the sysex formula as a String.

Yes, but string.gsub is for lua strings, not for juce Strings. It’s weird that function String:contains() return a lua string, so I can’t use again String:contains() with this string because it only works with juce Strings.

I’ve done this

myMethod = function( mod, value)

 jj =panel:getModulatorByName("modulator-3"):getMidiMessage(0):getProperty("midiMessageSysExFormula")

console(jj)
--f0 41 10 00 1d 12 k0 00 50 4b xx z5 f7
if string.find(jj,"k0") ~= nil then 
   hh = string.gsub(jj,"k0","f7") 
console(hh)
--f0 41 10 00 1d 12 f7 00 50 4b xx z5 f7
panel:getModulatorByName("modulator-3"):getMidiMessage(0):setProperty("midiMessageSysExFormula",hh,false)

end 

end

EDIT2 : corrected
WORKING !

I notice that you replace with something that looks like not an hexstring….

Thanks Zeoka, it worked!!

I didn’t realized that I was using getPropertyString instead of getProperty to get the midi message when I tried string.find and string.gsub.
