hi, so, i’ve got this nice little @joule pattern doubler in use for eons now, or maybe just a decade or something. it’s really to die for.
but i just realized that the doubler does not also double automation, which is a shame, as the result is:
what would the process of modifying this function to both double the pattern data and the automation data be?
function joulepatterndoubler()
local s=renoise.song()
local old_patternlength = s.selected_pattern.number_of_lines
local resultlength = nil
resultlength = old_patternlength*2
if not (resultlength > 512) then
s.selected_pattern.number_of_lines = resultlength
for track_index, patterntrack in ipairs(s.selected_pattern.tracks) do
if not patterntrack.is_empty then
for line_index, line in ipairs(patterntrack.lines) do
if line_index <= old_patternlength then
if not line.is_empty then
patterntrack:line(line_index+old_patternlength):copy_from(line)
else
patterntrack:line(line_index+old_patternlength):clear()
end
end
end
end
end
else
return
end
--Modification, cursor is placed to "start of "clone""
--renoise.song().selected_line_index = old_patternlength+1
s.selected_line_index = old_patternlength+s.selected_line_index
-- s.transport.edit_step=0
end
Then you would have to iterate all devices/parameters to copy any automation that is present.
But instead, why not use:
renoise.song().patterns.tracks:copy_from(other renoise.PatternTrack object)
Copy contents from other pattern tracks, including automation when possible.
function joulepatterndoubler()
local s=renoise.song()
local old_patternlength = s.selected_pattern.number_of_lines
local resultlength = nil
resultlength = old_patternlength*2
if not (resultlength > 512) then
s.selected_pattern.number_of_lines = resultlength
for track_index, patterntrack in ipairs(s.selected_pattern.tracks) do
if not patterntrack.is_empty then
for line_index, line in ipairs(patterntrack.lines) do
if line_index <= old_patternlength then
if not line.is_empty then
patterntrack:line(line_index+old_patternlength):copy_from(line)
else
patterntrack:line(line_index+old_patternlength):clear()
end
end
end
end
end
else
return
end
--Modification, cursor is placed to "start of "clone""
--renoise.song().selected_line_index = old_patternlength+1
s.selected_line_index = old_patternlength+s.selected_line_index
-- s.transport.edit_step=0
end

renoise.tool():add_keybinding{name="Mixer:Paketti:Joule Pattern Doubler",invoke=function() joulepatterndoubler() end}
and the copy_from other patterntrack object for me feels like i don’t know if i would know how to use it, esp since this doubling of patterns is done within the pattern, i.e. 64 row pattern turns into 128row pattern… so what am i copying it from?
if that api call mentioned “row 1-63” and “copy it to 64-128”, i’d get it, but i’m not clever enough to sort it out.
