im writing my first script and having two issues with it.
check out the script here: http://pastebin.com/c7t2xh48
basically its firing some osc messages with random values in random time.
now i want to controll the time value via my midi controller. i got midi values working in the script, but after some seconds my script isn’t responding to midi anymore.
if i use only the midi stuff from my script alone it seems that there is no problem. but when i combine the osc sending and the midi midi dies after a time…seems that the other stuff is running further.
the other isue i realised is that i can kill my os when i send to much osc values in an infinite loop . sure i shouldnt do this but did it once.
renoise then told me that i should kill the script, but renoise couldnt fully kill it and after a time my ubuntu screen got black
i’ve stripped down everything to a basic tool which only gets midi, prints the midicontroller infos and fires a timer.
No OSC or other stuff. After approx 1000 timer calls midi is stopping printing infos. I attached the tool maybe someone wants to test it.
did i mention that im on linux/ubuntu?
midi_callback is a local function inside an if…end condition. This function ceases to exist when the routine has been finished (condition has been met) and the Lua garbage collect is removing the executed code.
You could better make it a defined function outside the condition.
You should be aware that every variable or constant is local within its own scope. Which includes scopes of conditions and loops.
i thought about this also. if i do it like atached outside the condition. its happening also:
function myfunc ()
if (renoise.tool():has_timer(myfunc)) then
renoise.tool():remove_timer(myfunc)
end
renoise.tool():add_timer(myfunc, 50)
end
myfunc()
rprint(renoise.Midi.available_input_devices())
local inputs = renoise.Midi.available_input_devices()
local midi_device = nil
local device_name
if not table.is_empty(inputs) then
device_name = inputs[5]
-- stop dumping with 'midi_device:close()' ...
end
local function midi_callback(message)
assert(#message == 3)
assert(message[1] >= 0 and message[1] <= 0xff)
assert(message[2] >= 0 and message[2] <= 0xff)
assert(message[3] >= 0 and message[3] <= 0xff)
print(("%s: got MIDI %X %X %X"):format(device_name, message[1], message[2], message[3]))
end
-- note: sysex callback would be a optional 2nd arg...
midi_device = renoise.Midi.create_input_device(device_name, midi_callback)
Well you are not doing anything else either.
Your code executes and then the scripts stops functioning.
Just add some dummy GUI dialog to keep the stuff in memory.
This works:
function myfunc ()
if (renoise.tool():has_timer(myfunc)) then
renoise.tool():remove_timer(myfunc)
end
renoise.tool():add_timer(myfunc, 50)
end
myfunc()
rprint(renoise.Midi.available_input_devices())
local inputs = renoise.Midi.available_input_devices()
local midi_device = nil
local device_name = nil
if not table.is_empty(inputs) then
device_name = inputs[1]
-- stop dumping with 'midi_device:close()' ...
end
function midi_callback(message)
assert(#message == 3)
assert(message[1] >= 0 and message[1] <= 0xff)
assert(message[2] >= 0 and message[2] <= 0xff)
assert(message[3] >= 0 and message[3] <= 0xff)
print(("%s: got MIDI %X %X %X"):format(device_name, message[1], message[2], message[3]))
end
function script_loop()
local vb = renoise.ViewBuilder()
local CONTENT_MARGIN = renoise.ViewBuilder.DEFAULT_CONTROL_MARGIN
local BUTTON_WIDTH = 2*renoise.ViewBuilder.DEFAULT_CONTROL_HEIGHT
-- create the main content column, but don't add any views yet:
local dialog_content = vb:column {
margin = CONTENT_MARGIN
}
local busy_holder = renoise.app():show_custom_dialog(
"Keeping Renoise busy", dialog_content)
busy_holder:close()
midi_device = renoise.Midi.create_input_device(device_name, midi_callback)
end
script_loop()
Don’t forget to set the correct midi devicenumber. (Mine is 1)
. sure i shouldnt do this but did it once.
