Sometimes I find myself needing to use toggle-dsps tool http://tools.renoise.com/tools/toggle-dsps to render samples as they run througth fx -> sends -> more fx -> master dsps/vst
but I really like just clicking render to sample and its done. So please could somebody who is savy with scripting either make this or maybe give me some pointers on how to make this:
Right click on pattern editor, Click Dry Render on menu, Toggles off all dsps and vst, does a render to sample then toggles all the dsps that were on before back on, all with one click.
You would need to write a renderer of your own with this function:
-- Start rendering a section of the song or the whole song to a WAV file.
-- Rendering job will be done in the background and the call will return
-- back immediately, but the Renoise GUI will be blocked during rendering. The
-- passed 'rendering_done_callback' function is called as soon as rendering is
-- done, e.g. successfully completed.
-- While rendering, the rendering status can be polled with the song().rendering
-- and song().rendering_progress properties, for example, in idle notifier
-- loops. If starting the rendering process fails (because of file IO errors for
-- example), the render function will return false and the error message is set
-- as the second return value. On success, only a single "true" value is
-- returned. Param 'options' is a table with the following fields, all optional:
--
-- options = {
-- start_pos, -- renoise.SongPos object. by default the song start.
-- end_pos, -- renoise.SongPos object. by default the song end.
-- sample_rate, -- number, one of 22050, 44100, 48000, 88200, 96000. \
-- -- by default the players current rate.
-- bit_depth , -- number, one of 16, 24 or 32. by default 32.
-- interpolation, -- string, one of 'cubic', 'sinc'. by default cubic'.
-- priority, -- string, one "low", "realtime", "high". \
-- -- by default "high".
-- }
--
-- To render only specific tracks or columns, mute the undesired tracks/columns
-- before starting to render.
-- Param 'file_name' must point to a valid, maybe already existing file. If it
-- already exists, the file will be silently overwritten. The renderer will
-- automatically add a ".wav" extension to the file_name, if missing.
-- Param 'rendering_done_callback' is ONLY called when rendering has succeeded.
-- You can do something with the file you've passed to the renderer here, like
-- for example loading the file into a sample buffer.
renoise.song():render([options,] filename, rendering_done_callback)
-> [boolean, error_message]
Then load the wav file back into an empty instrument.
The toggle_DSPs script already helps you out quite a lot.
For the start-pos and end-pos , you need the renoise.song().patterns.tracks.lines.note_columns.is_selected option to determine the start and end-boundary of a selection.
To figure out if a sample buffer has sample data you need:
local empty_sample_instrument = nil
for x = 1, #renoise.song().instruments do
empty_sample_instrument = renoise.song().instruments[x].samples[1].sample_buffer.has_sample_data
if empty_sample_instrument == false then
empty_sample_instrument = x
break
end
end
Note the above is basic, you also would need to figure out if the instrument has a VST plugin loaded or has an external midi device configured to be sure it is absolutely not used.
To reload the created wav file into an empty sample buffer, you need
renoise.song().instruments[empty_sample_instrument].samples[1].sample_buffer:load_from(filename)

PS I’m looking at freeze track tool by mxb to fill in the blanks
nl.jeweett.RenderTrackNoFX.xrnx v0.1
Two options: track and selection. Mind you the ‘render selection dry’ is not a real ‘render selection’; it only renders what’s on the current track inside selection. Because like vV said, Render to Sample is not available in the API as of yet, and it’s something that can be a little bit annoying to ‘remake’ with the regular render function. I don’t really mind the work of this though, because it’s typically one area of the Renoise API that I hadn’t touched yet so now I know a little bit more.
You’re free to study the code (and possibly, the progress of the code) at github
Also, let me know how well it works, what doesn’t work about it, etc.
PS., still, if you want to know about renoise tools, study any of the tools I’ve made at this link, there’s some starter-stuff in there that you can get ideas from, e.g. my first was “MidiSkip”, some other cool but simple ones are AutoSelectInstrument; AwesomeSawce; BestViews; BlockLoopSize; Clean Drums; EditStepTools; MiniTab (beta); MonoDelay2; Note Repeat; Pdub; PlayAndLoopPattern; RecentFiles; SirDanceALot; SliceNExact
Hi Cas, one more request for this tool, can the ‘pre and post fx volume’ be set to 0db during the render then back to what it was before. The reason for this is if you have a lower or higher volume and do the render you have to adjust the renders volume after, this tool is so easy to add little slides and reverses to sliced up samples without needing more tracks but that’s the only thing that lets the process down a bit. When I get a bit of free time I will have a go at making a simple tool, Thanks again.
