I’ll increase the limit in the next version 
Actually completely blown away by this, all the “It wont be a tracker anymore” garbage over the years is just completely blown out of the water, this should either be native, or every effort should be made by the developers to make sure every single thing you need in the API moving forward is added.

Used FL studio as a VST instrument back in the day explicitly for its Piano Roll, this Tool is a game changer for my ReNoise life.
It’s a shame I just noticed it exists, massive Thank You for the time and effort invested!

I am just trying this out for the first time, and am very happy with what I see. Strangely though, whenever I click my mouse is being moved to the bottom left of the grid. I don’t see anyone else experiencing this, is it just me? I’m using a trackpad on my laptop right now, which is kind of painful. I’ll have to mess around with this more when I have a mouse. Maybe I can figure out what is causing it.

Seriously,use a mouse.
It’s the snap function of the Xypad, which i’m using for mouse actions in the piano roll. I need this snap function to detect left mouse click release. Whenever the Xypad get the value of the snapX and snapY, the tool knowns, that the left mouse button was released
It’s recommend to disable mouse warping in the Renoise preferences, because this causing the mouse jumps on Xypad’s with enabled snap:
Ah thanks, that makes sense. I see that it’s in the readme now. Everything else works so well I thought I just had a weird bug! Hopefully the devs can add something to the API for you, because I do like having warping on the sliders, but for now it is pretty good.

Yeah, i suggested a new parameter for the Xypad viewbuilder control in the API to disable mouse warping per
control. Would solve this issue and we can still use mouse warping on other XYpads.

com.duftetools.SimplePianoroll V3.0 (for Renoise 3.3)
Happy new year, everyone! New year, new update 
I’ve added chord detection. I found this very useful for several cases. I didn’t study music theory, rather taught myself a lot. I hope I didn’t made any mistake there. It works for playing and selected notes. It also use the current scale to detect the scale degree:
I’ve added a new way to do step sequencing in the piano roll view:
Just use the computer keyboard to play notes and then cursor keys right to draw the notes. Please note, this works, when the song is not playing. There is a video about how this is this is working in Ableton. Its a similar approach.
Right cursor key to draw notes. Left cursor key to remove notes.
Full changelog:
- feature: add chord and scale degree detection
- feature: add step sequencing with cursor keys and currently playing notes
- feature: add option for shading root notes
- improved: better handling of losing window focus (try to get focus back)
- improved: add edit with piano roll to mixer view
- fix: wrong root key labeling in scale auto mode
- fix: note doesn’t move instant sometimes, when using mouse
- fix: shading was going to default color value “{0,0,0}”
- fix: bad preview polyphony for transposing
- fix: wrong piano key coloring, when playing notes during scrolling
- fix: bad ghost track index error, when ghost track was deleted
- fix: some more nil errors

If have some suggestions in optics for better oversight in config dialog. smal things i know, but smal things
count too.
-
the input boxes should be placed in same vertical line and with anchors / aligned to right
-
the optiontext in Value select boxes (combobox) should aligned on right to
-
2 possibilitys for control lenghts of the input/comboboxes
3.1. make its so long till the left description labeltext (Value: [ I n p u t b o x C o n t r o l ]
or
3.2 use a line of points till controls horizontal startpos (Value: ............[Inputbox Control]
hope you understood what i mean
the mixershortcut in V3.0 is nice!

Suggestion, but I don’t know if it is possible in current version of Renoise 3.3.2.
Can you add a UI component similar to Note Length, Velocity, etc. which will assign Instrument number? For example, if first use the pattern editor to input notes for instrument 02, but when I open the pattern in the Simple Piano Roll, I want to highlight one note and change just that note to instrument 03.

Yep sure its possible. This would allow us to use multiple instruments. Its currently restricted to just one instrument at the moment. I’ll add this to my todo.

com.duftetools.SimplePianoroll V3.1 (for Renoise 3.3)
Hello everyone, new update. Just several minor changes and fixes.
Automatically remove unused note columns
The piano roll already supports to add automatically new note columns, when the option is enabled. And now it also removes empty ones. Will be applied automatically on note editing actions.
Mouse warping compatibility mode
There is a mouse warping compatibility mode. It will disable some functions where the current left mouse button state is needed (visible select rectangle for example). This will fix the mouse cursor jumping. Its still recommend to disable mouse warping.
Easier note slides (VSTi)
I recently used note sliding alot, also in my last song: Sunbeams.
I found out that FLStudio always plays the last added note in a row first. With this in mind, its pretty easy to create note slides. Just draw you melody first and then add note slides afterwards. No delaying of these slides notes is needed.
Renoise is playing the notes per column from left to right on each line. So the piano roll now tries to add new notes to the first non conflicting available column. It moves the other notes on the same line to the next column on the right.
Edit a track via instrument per context menu
It’s searching for the correct track in all patterns, switch to it and opens the piano roll.
Full changelog:
- feature: easy switch between relative minor / major (button in set scale dialog or while holding ctrl key and click current scale)
- feature: edit pattern with simple pianoroll from instrument box
- feature: add option to set Renoise computer keyboard velocity to the current preview velocity
- feature: add option to allow move and scale of notes in pen mode
- improved: also automatically remove note columns, when option for automatically add note columns is enabled
- improved: add mouse warping compatibility mode (fix mouse jumping, when mouse warping is needed)
- improved: realigned input fields in preferences
- improved: add menu entries for piano roll and preferences
- improved: reduce full piano roll refresh on selection changes
- changed: when removing notes, move other notes on the same line to free columns
- changed: try to force new notes always on the first column for better legato portamento without delaying (playback order new notes first)
- fix: missing undo description for step sequencing
- fix: also sort notes by column, so notes doesn’t jump between columns to often
- fix: click issue with scale note button on overlapping notes
- fix: wrong fake alpha blending coloring

Very good work mate! I love the 2 new options for getting trackcolors as notecolors! i found a little bug. If you have both of these option activated and open pianoroll window all works correct, but when you change the track he dont use the colors from the actual track to repaint pianoroll notes, he use the colors from the [selected channel] predecessor.
That means if you have three tracks with track colors
track1 red track 2 yellow track3 green
- you open track 1 → Notecolors painted red (correct)
- you change track to “track2” colors should repaint as yellow, but painted still red (only new played colors change to yellow)
- you change track to “track3” colors should repaint as green, but painted still yellow (only new played colors change to green)
the behaviour is reproducable
Maybe a missing repaint() call bug at trackchange event, or a colorarray Indexbug i think, should be easy to fix.

Wow i just discovered this tool - it’s awesome! Congrats and respect to the creator.
I did have a few crashes though. Mainly when pressing UNDO. Will paste here.
Please contact the author (dufte (toimp)) for assistance…
std::logic_error: ‘invalid selected_note_column_index index ‘3’. valid values are (1 to 2).’
stack traceback:
[C]: ?
[C]: in function ‘__newindex’
[string “do…”]:22: in function <[string “do…”]:9>
main.lua:826: in function ‘jumpToNoteInPattern’
main.lua:966: in function ‘updateNoteSelection’
main.lua:4184: in function ‘fillPianoRoll’
main.lua:5275: in function main.lua:5244
Also, on my trackpad (mac) I could get it to scroll up and down with 2 fingers, but not left & right?
It also keeps turning my main renoise pattern scroll/follow off. is that a bug or a feature? Either way I would appreciate it if it switched it back on after the piano-roll is closed.
And finally - every now and then, it puts random notes in to the grid. Strange.
But again, man, wow, thank you !

Got this sometimes, too. I made a small change to fix this in the upcoming version. When you have an easy way to reproduce this issue, it would be nice.
Its because this gesture will be triggered as “scrolling”. Left to right swiping is currently not possible do API limitations, but you can use it with option key / alt key and up and down to scroll left and right.
Maybe a double click event will be fired. Try to set it to the lowest value, if you don’t need it at all:
