I have created another crazy function related to insert a new metronome…
I need the code to jump to the last instrument. The API does not seem to have a specific code and seems to need to iterate?Do you have an example of the exact code?
Selecting a particular instrument number is simple: song.selected_instrument_index = 10 (jumps to instrument 10, range 1 to 255) Returning the total number of instruments available would be sufficient.How do I get this number?
function amic_CH03_4A() --CREATE METRONOME AND CONFIGURE
local song, app = renoise.song(), renoise.app()
local sid0 = song.selected_track_index -- start
song:insert_track_at(song.sequencer_track_count + 1)
song.selected_track_index = song.sequencer_track_count
local sid = song.selected_track_index
song.tracks[sid].name = "Metronome"
song.tracks[sid].color = {00,00,00}
song.tracks[sid].color_blend = 50
song.tracks[sid].volume_column_visible = F
song.tracks[sid].visible_effect_columns = 0
song.selected_track_index = sid0 -- return start
--- ---
print("n-intr: ", renoise.Song.MAX_NUMBER_OF_INSTRUMENTS )
song.selected_instrument_index = 10 -- Jump Instrument 10 to start -- replace by jump last instrument
song:insert_instrument_at(10)
app:load_instrument("Xrni/Metronome.xrni") --Insert Metronome
app:show_status( "GT16-Colors: Metronome Inserted in last track." )
--- ---
song.transport.bpm = 176 -- 32-999 BPM
song.transport.lpb = 8 -- 1-256 LPB
song.patterns[song.selected_sequence_index].number_of_lines = 96 --LINES per pattern
-- code for write specific notes in selected pattern with selected instrument
end
On the other hand, in the same function at the end, I would add the writing of some 4 notes in the selected pattern with the selected instrument. This is possible?If so, what is the code?
The whole function would be triggered with a simple button.
Explanation of function:
Insert a new track in last position, and change propierties (name, color…).
Insert a new instrument (metronome, a xrni) in instrument number 10 of instrument box ( I want it to be the last available )
Change some parameters, BPM, LPB and number of LINES in selected pattern.
Thanks to this you can include many metronomes, different speeds, sounds or volume…
To end, I just need to get the maximum number of slots of instruments available in the instrument box. This is not therenoise.Song.MAX_NUMBER_OF_INSTRUMENTS, this is 255.
For example, when starting a new song (new XRNS) the number is 10.
How to get this? Thanks!
EDIT :Wow, I need to deactivate Renoise’s metronome, in case it is touched. But this I know how to do.
renoise.song().selected_instrument_index = #renoise.song().instruments
-- which is also the same as:
-- renoise.song().selected_instrument_index = table.getn(renoise.song().instruments)
Note that this only work on tables with indices (1, 2, 3, 4…) as keys. In other cases, you’d have to iterate using pairs (or more likely: select a better data structure for your table).
PS. Shortcut for writing better code in general: try to stay within 80 columns in your text editor
@joule. Wow, that’s right, I forgot the pad (#). Thanks!!!I had used it many times with functions with tracks.
I am very grateful for your advice.At menoud, I’m struggling with the issue of shortening and sorting the code, not to fill it with redundant information.
In the end I have had to add some new lines to solve possible errors.This is how I have stayed the code:
function amic_CH03_4A() --INSERT METRONOME AND MORE
local song, app = renoise.song(), renoise.app()
local sid0, sin0 = song.selected_track_index, song.selected_instrument_index --initial track and instrument slot
if #song.instruments < 255 then
song:insert_track_at(song.sequencer_track_count + 1) --insert last new track
song.selected_track_index = song.sequencer_track_count --select last track
local sid = song.selected_track_index
song.tracks[sid].name = "Metronome" --rename name metronome
song.tracks[sid].color = {00,00,00} --change color track
song.tracks[sid].color_blend = 50 --change color blend track
song.tracks[sid].volume_column_visible = F --hide volume column
song.tracks[sid].visible_effect_columns = 0 --hide visible effect column
--print( "n-instr-max: ", renoise.Song.MAX_NUMBER_OF_INSTRUMENTS ) -- =255
--print( "n-inst-aval: ", #renoise.song().instruments )
song.selected_instrument_index = #song.instruments --jump last slot available in intrument box (1-255)
song:insert_instrument_at(#song.instruments) --insert instrument in last slot available
app:load_instrument("Xrni/Metronome.xrni") --insert Metronome XRNI
local pattern = song:pattern(song.selected_sequence_index)
pattern.number_of_lines = 96 --change LINES per pattern
local note_column = pattern:track(sid):line(1):note_column(1)
note_column.note_value = 48 --(0-119, 120=Off, 121=Empty) --C-4
print( "n-inst-aval: ", #renoise.song().instruments )
note_column.instrument_value = #song.instruments - 2 --(0-254, 255==Empty)
local note_column = pattern:track(sid):line(25):note_column(1)
note_column.note_value = 48 --C-4
note_column.instrument_value = #song.instruments - 2
local note_column = pattern:track(sid):line(49):note_column(1)
note_column.note_value = 48 --C-4
note_column.instrument_value = #song.instruments - 2
local note_column = pattern:track(sid):line(73):note_column(1)
note_column.note_value = 50 --D-4
note_column.instrument_value = #song.instruments - 2
song.selected_track_index = sid0 --return initial track
song.selected_instrument_index = sin0 --return initial instrument slot
song.transport.bpm = 176 --BPM (32 to 999)
song.transport.lpb = 8 --LPB (1 to 256)
song.transport.metronome_enabled = false --metronome off
app:show_status( "GT16-Colors, AMIC: Metronome Inserted in last instrument slot." ) --status
else
app:show_status( "⚠ GT16-Colors, AMIC: you are 255 slots used. Please, delete a instrument slot to insert Metronome!" ) --status
end
end
This code already works perfect! It is only necessary that the archive “Metronome.xrni” is configured according to the code (or vice versa).In this way, it is possible to create similar functions with a multitude of different metronomes…
I have realized that I can reduce the code of the function just by adding a single note (9 lines less). Would use a phrase with a only note related.It’s simpler, and I can create multitude of metronomes just by using a XRNI only.
Maybe I built an independent tool with just this idea: multitude of controllable metronomes within reach of a single button.
