API for access to renoise’s 4 clipboards.
Hey Konrad,
A solution to this could be adding an idle notifier that checks the playback_pos. If you take a look at Nibbles, you’ll see how the idle notifier can serve as a game stepper. You can change the os.clock() time checker to a playback_pos checker.
-- Run every line
if (renoise.song().transport.playback_pos == last_idle_time) then
return
end
last_idle_time = renoise.song().transport.playback_pos
For heavy processing you will encounter “frame dropping” when the idle notifier doesn’t fire between playback_pos. It will skip a line so to speak so keep that in mind when creating the stepper.
You can add and remove the idle notifier on renoise.song().transport.playing_observable to reduce overhead.
I seem to be developing a tool in a similar genre as you, it writes to the pattern editor during playback at the playback_pos. I hope to post it in a few days but I could send it to you (i if you want to take a look at how I address these issues.
I ask for a way to know the current sampling frequency of the audio driver, so that the creation of samples can take it into account
- Some way to define selections in Pattern Editor
To set initial focus in the relevant GUI elements:
vb:textfield {
focus = true
}
enables complete keyboard control in for example, search tools
My “most wanted” list (not in any particular order)
- Access to the list of scheduled patterns (could be read-only). More info
- A way to properly clear text from a ViewBuilder object -> e.g. supply “nil” to return it to initial, empty state
- A way to detect which matrix slot has been muted (pattern_slot_mutes_observable). More info
- Make the pattern_assignments_observable tell us what pattern was changed, and from what index
- More control of the recording dialog: FX track, sync to pattern, create new instrument etc.
- Default value for Slider, MiniSlider, RotaryEncoder (reset to this position when double-clicked)
- Bipolar support for Slider, MiniSlider, RotaryEncoder (like e.g. the Cabinet Simulator EQ’s)
- Range slider (like the zoom slider of the waveform editor)
- Fix: declaration of loop points in a song using transport.loop_range_beats will snap to coeff. More info
- Ability to retrieve the current volume level at any point in a DSP chain (imagine a mixer application using this)
- Access to thecurrently playing voices- whether a sample is playing, it’s current playback position etc.
- Access to the status of a sample - whether it’s currently being loaded from disk
- Ability to show/hide the (detached) instrument editor
- Ability to start/stop phrase playback “preview”(independently of the song)
- Access to UI theme colors (e.g. to set a button to the “selected” state)
- Ability to detect when a key has been released (dialog keyhandler)
- Access the selected phrase index when the instrument isn’t selected (selected_phrase/_index is a global property)
Features that have been implemented
~~* A way to determine which slots are selected in the matrix
- “is_midi_mapped” property for parameters (like “is_automated”)
- A way to determine mixer PRE/POST state~~

I request a “column by column” iterator.
The closest thing I can see is renoise.song().pattern_iterator:lines_in_track()
The problem I’m having, which I will work around with cheap hacks, is that the above iterator will cycle through each column before moving to the next track.
ideally, some sort of “vertical iterator, left to right” would be a life saver.
Or, am I missing something obvious?
Cheers.
renoise.app():show_custom_dialog(“Title”, dialog_content,keyhandler_func, close_function)
[b]
close_function[/b] is fired when you press the [x] on a dialog to close it.
Would be greatly useful when trying to release all relevant notifiers.
Brainstrom warning 
:
Ability to attach invisible scripting meta data id`s into the song. i.e.
renoise.song():add_id (“Song_in_A#”)
renoise.song().pattern[1]:add_id (“Miss_this_pattern”)
renoise.song().pattern[1].track[2]:add_id (“true”)
These id`s get saved in the renoise song invisible to the user, with maybe a user preference in renoise to allow this?
Silently in the background renoise could maybe prefix the ids with the script xml id?
Now you can use these id`s to trigger events with observable transport, save per song preferences etc.
The advantage of this over simple preferences would be that when a user deletes/ clones a pattern in the song all the meta data is destroyed or cloned accordingly??
I would like to have the possibility to make a key handler function respond to a key release as well as a key press. So that I could do something like this:
if key.name == "z" then
trigger_note(instrument, track, note, velocity)
elseif key.name == "z_off" then
trigger_note_off(instrument, track, note)
end
Also, this:
I’d like to request a function named dbug() be added to Lua.Standard.API.lua. Basically a compliment to oprint, rprint, and print.
Example:
function dbug(msg)
if _MAGIC_FUNCTION(msg) == 'object' then oprint(msg)
elseif type(msg) == 'table' then rprint(msg)
else print(msg) end
end
This would save me a lot of grief.
oprint is not really an equivalent to rprint. It does not print an objects “state” but its available functions and properties.
If this nevertheless would be useful, you can use something like to roll up your own “dbug”:
function is_class_object(object)
local is_base_type = {
["nil"]=true, ["boolean"]=true, ["number"]=true,
["string"]=true, ["thread"]=true, ["table"]=true
}
return (not is_base_type[type(object)])
end
For me, it’s better than the script crashing because I chose the wrong variation of print.
I just needed a quick all-in-one for debugging purposes.
The code snippet will do the job.
Thanks!

Midi-mapping
- Possibility to bind a midi-mapping to a regular keybinding, such as CC#XX to “Pattern Editor->Player->Play Current Line”
Cursor Focus in GUI:
Script is allowed to set cursorFocus on a specific button, or window in the Script GUI
Direct function call for “play current line of current track” or “play current line of current pattern”.
just like if you pressing return for playing only one line. Without any position scrolling. And without enabling the play symbol! And please BEFORE the playing of keyboard or midi input happens!!! So it plays like it wasn’t edited.

what Joule requested athttps://forum.renoise.com/t/the-api-wishlist-thread/29285:
renoise.app().window.selected_focus_index = 0
and I echoed at "I too would love to set TrackDSP_focus , TrackDSP_loader_focus , DiskBrowserFiles_focus , DiskBrowserFolders_focus , InstrumentBox_Focus , PatternMatrix_Focus… and many others. "
True control over DC Offset Auto On/Off mode in LUA scripting:
renoise.song().selected_track.devices[2].parameters[2].value=1 (when DC Offset is Device#1 (aka 2), changing this does not create a new dcoffset device that would automatically have autoDC on.
#Line-In Device updates with more API functions:
Setting of Channel, input-channel (left-right-stereo)
- Load & Save DSP Chains (.xrnt)
- Load & Save Instruments (.xrni) -> having these allows for mapping shortcuts to load both an instrument and a dsp-chain. priceless.
- External macOS Clipboard access (if sample data is in clipboard, can paste to Renoise – if sample data is copied in Renoise to clipboard, can paste to another app)
- Pattern Sequence Matrix Visible True/False (maybe this is possible nowadays?)
- “API for access to Renoise’s 4 clipboards would be awesome”
- possibility to add menu entries into this row:
- 7890
- Read LFO device setting (amount) and make that amount available as a input in scripting (
- Script can map a LFO device to the Sample loop start & sample loop end parameters.)
renoise.app().window.upperframe.masterspectrum.drawingmode = (selection of the 4 possible drawing modes)
7891 
Allow retreival of the exact position of the cursor on ins/pan/vol/delay column level:
renoise.song().selected_note_column_object(renoise.song().selected_note_column_index) returns:
1: cursor is in the notecolumn
2: cursor is in the instrument column
3:cursor is in the volume column
4:cursor is in the panning column
5:cursor is in the delay column.
My ‘simple’ requests:
- Currently we have sample_buffer:set_sample_data(channel, frame, value). Iterating over this in Lua is slow. I think it would be great if we could read/write a channel of data as a Lua table. e.g. sample_buffer:set_sample_data_block(channel) = {0,0,1,1}. This would fail if #table is not equal to sample_buffer.number_of_frames.
- API access to instrument parameters (as frequently requested).
- Access to a FFT and IFFT function. Presumably they must exist due to the frequency spectrum view. This can be implemented in Lua but it’s not the fastest method in the world.
I would need a function that pauses the recording of undo, and one that resumes it.
Sometimes you make scripts that temporarily alters a lot of parameters, but you don’t want these actions to clutter the users undo buffer.
renoise.song().sequencer.selection
returns a table of the pattern numbers selected in the sequencer:
2245 selected.PNG
i.e above returns {188,183,194,196}
