Help Tried to index memoryblocks..

[zeoka]

Hi i try to index many memoryblocks to have multiple usages with them
( in this case a button to send a midi message)
– i’ ve a method with sound = print(..
that gives error : At line[-1]: [C] No such operator defined

– and other method with sound = …
that gives error : At line[-1]: [C] std::exception:’unable to make cast’

i think i’m near but a thing is not correct
please if anyone see…..

It’s seems lua editor has a problem with long lines because i can’t see the end of memoryblocs in Bank2()….. may be it is the exception ?
The script was made in TXT file and pasted in Bank2 because i couldn’t in lua

Ok i get it

mytable = function(mod, value)

send2mem = panel:getModulatorByName("modulator-2")
   sndmp = send2mem:getValue()
ptchslct = panel:getModulatorByName("modulator-1"):getValue() 
Bank2()

if sndmp == 1 then 
bk2 = factory2001[ptchslct + 1]
-- just a text 
panel:getLabelComponent("modulator-3"):setText (bk2:toHexString(1))
-- the midi

m = CtrlrMidiMessage(bk2:toHexString(1))
panel:sendMidiMessageNow(m)

 
end

end

but
i send a full midi message with f0 and f7
and i need to remove the six first bytes of my messages to replace by variables
so my question is how to add variables at the begining of “bk2” data ?
tried :
bk2full = f0,(bk2),f7
or
bk2full = string.format(f0%sf7,bk2)
m = CtrlrMidiMessage(bk2full:toHexString(1))

I really can’t figure how to rebuild data….

send2mem = panel:getModulatorByName("modulator-2")
   sndmp = send2mem:getValue()
ptchslct = panel:getModulatorByName("modulator-1"):getValue() 
    byte = {}
 byte[1] = 240
 byte[2] = 62
 byte[3] = 16
 byte[4] = 0
 byte[5] = panel:getModulatorByName("modulator-4"):getValue()
 byte[6] = panel:getModulatorByName("modulator-5"):getValue()
 byte[7] = panel:getModulatorByName("modulator-6"):getValue()
     syx = MemoryBlock (byte)
           Bank2()
--trigger btn
if sndmp == 1 then 
     bk2 = factory2001[ptchslct + 1]
 fullmsg = MemoryBlock(string.format("%s %s", syx:toHexString(1),bk2:toHexString(1)))
-- just a temp text to see 
           panel:getLabelComponent("modulator-3"):setText(string.format("%s %s", syx:toHexString(1),bk2:toHexString(1)))
-- the midi
       m = CtrlrMidiMessage(fullmsg:toHexString(1))
           panel:sendMidiMessageNow(m)
end

end

I ve just copied formula used for text info into a new memoryblock..

a entire day for that

yeah those are rough days but they’re usually followed with a lot of things falling into place faster than you had planned… hopefully that’s what you’re experiencing now 🙂

Stupid question: I notice when you convert to a hex string you’re adding a 1 between the parenthesis.. what’s the difference between:
(blah:toHexString()) and (blah:toHexString(1))? I don’t think I’ve ever put anything within the “()” when converting like that.

It’s a grouping parameter, 1 means one-byte then space, 2 means 2 bytes then space etc.

[zeoka]

Yes
Without : this is for a byte
and with : this is for user data

I start to like LUA tables i will use them more…
for receive patch ,save mod to custom Library , send patch properly to synth when ctrlr snapshots change

Yeah next step is draw and all mouse actions but i have to do a lot before

Hi this is an simple example to have an index variable :

bufftype = panel:getModulatorByName(“modulator-5”):getValue()
typval = ptchtype:getValue()
if typval == 0 then
if bufftype == 0 then byte[6] = 48
elseif bufftype == 1 then byte[6] = 64
elseif bufftype == 2 then byte[6] = 65
elseif bufftype == 3 then byte[6] = 66 end
elseif typval >= 1 then
if bufftype <= 1 then byte[6] = (bufftype *32) + 32 end end end this is the byte 6 of "syx" memoryblock seen above.This script is added to the script above , instead of previous line + to the attached mod The cool thing with tables :it's they can be used several times for multiple purposes. EX in theory the same table can receive a patch from a device and from a file or ctrlr snapshots
