Yep. TGrains actually asks for the grain’s center position in the buffer (in seconds). So I’m calculating this just by taking start + (num/2) to get it in samples. Then I divide by the buffer’s sample rate to get that position in seconds.
Let me know if that clarifies!
T
Ah, i wasn’t aware TGrains needs the center position! (Buts still reads from beginning i assume)
So for PlayBuf id just need start in any case and can remove num/2!
Thanks!
Correct.
Yes, and, PlayBuf’s argument startPos is in samples, so you shouldn’t use the divide-by-samplerate either.
Hi @tedmoore,
im encountering this error for the first time while sorting the infos from each slices of a cluster into buffers (block number 7 from code above).
I had gotten warning about empty clusters, could that be a reason? I don’t understand though why the destination buffer is supposedly invalid as they’re allocate as usual!

Hmm, yes I suppose rather than asking for the size of the Dictionary, it should be the maxItem of the keys.
Try replacing this line:
~play_info_clusters = {Buffer(s)} ! ~clusters.size;
with:
~play_info_clusters = {Buffer(s)} ! ~clusters.keys.maxItem;
I’m not able to test right now, but this should do it.
Notice that if you have empty clusters here, you’ll end up with some buffers that are 0 samples long, which might cause some problems farther down the line during playback or whatever, so just keep that in mind! Maybe check for it at some point.
Ah yes, makes sense, ill try this out after another longer round of Umap processing;)
What is rather odd though is that i get quite a lot of empty clusters warnings after running seeded Kmeans, but none of the buffers are actually empty!?
I believe this is a question we should direct towards @weefuzzy. I too have noticed that sometimes I will get an “empty clusters” warning but then the result of KMeans doesn’t have any empty clusters. I believe this is because it’s reporting that there is an empty cluster at some point in the process, but by the end of the process no clusters are empty?
It does seems strange though that you’d get this when doing the seeding because all those seeded means have lots of points around them!
Precisely! Here is an example: It actually seems to post a warning for each seeded Kmeans cluster!

Looking over the code, I think it’s a debugging artefact from when it was being written: the warning is deep in the algorithm code and writes straight to console, meaning that it will show up in SC but not in Max or PD. I’ll take it out.
Hmm. Bummer. I’ll take a look soon.
Going back to this code after an involuntary break, im getting the following error, which if im right didn’t happen before.
I upgraded FluComa in the meanwhile, not sure if thats the reason?
this is the part of the code:
(
var kdtree = FluidKDTree(s);
var buf_2d = Buffer.alloc(s,2);
var scaler = FluidNormalize(s);
~ds_norm = FluidDataSet(s);
~ds_umap=FluidDataSet(s).read("/Users/jan/Sound/Recordings/alog/slices/ds_umap.json");
// whatever the output of umap is, scale it to be between 0 and 1 so that it will look nice in the plotter
scaler.fitTransform(~ds_umap,~ds_norm);
kdtree.fit(~ds_norm);
~ds_norm.dump({
arg dict;
var previous, fp;
fp = FluidPlotter(bounds:Rect(0,0,800,800),dict:dict,mouseMoveAction:{
arg view, x, y;
[x,y].postln; // get the (normalized) x, y position of the mouse and...
buf_2d.setn(0,[x,y]); // load it into a buffer so that...
kdtree.kNearest(buf_2d,{ // it can be passed to the kdtree to find hte nearest neighbour, which is reported back...
arg nearest; // here
var index = nearest.asString.split($-)[1].asInteger; // peel off the index of the slice
previous = nearest;
"nearest point is: %".format(nearest).postln;
{
var startPos = Index.kr(~indices,index); // look up the start position
var dur_samps = Index.kr(~indices,index + 1) - startPos; // calculate the duration in samples
// play the buffer starting from the start position
var sig = PlayBuf.ar(1,~loader.buffer,BufRateScale.ir(~loader.buffer),startPos:startPos).poll;
var dur_sec = dur_samps / BufSampleRate.ir(~loader.buffer);
var env = EnvGen.ar(Env([0,1,1,0],[0.03,dur_sec-0.06,0.03]),doneAction:2);
sig.dup * env;
}.play;});
});
});
);
which returns this:

RECEIVER: Window
thanks for any suggestion son how to get around this!

Hi @jan,
The error message is from the SC GUI stuff, complaining that its been called from the wrong thread. I think you can only schedule GUI updates on the AppClock. What’s probably happening is that the callback for ~ds_norm dump is on the SystemClock. You could try wrapping the contents of that function with defer.
hi @weefuzzy,
if wrapping the function means to replace .play with .defer it didn’t help unfortunately, as it returns the same error…is there maybe another workaround?
wonder what caused this change also, as it used to work no problem!
I mean making sure the code that creates FluidPlotter is deferred. If you check out the example code in the FluidUMAP help file it might be clearer what I mean: flucoma-docs/example-code/sc/UMAP.scd at 8d81a588ba33ba66d5cb4d3844019ba7e0bd5733 · flucoma/flucoma-docs · GitHub
You’ll see that inside the dump callback, the code to instantiate the plotter is all wrapped in defer:
reduced.dump({
arg dict;
var xybuf = Buffer.alloc(s,2);
defer{
FluidPlotter(dict:dict,mouseMoveAction:{
...
can it be that wrapping it in defer interferes with the sound in the example being played back?
this code with the defer function added gives no sound when moving over the plotter:
s.boot;
// 1. Load a folder of sounds

It shouldn’t do (the UMAP help follows the same basic path and makes sound ok, at least here: does that play back for you ok?). Is there an error message? Do you see your "nearest point is: %".format(nearest).postln; message posted?
yes, the UMAP example works and sounds fine!
in my example theres no error message, i just get the [x,y] coordinates and no “nearest point” post.
Hmm, is it possible that you’re missing the k argument to kNearest here?
Perhaps try changing to
kdtree.kNearest(buf_2d, 1, {
I’m surprised it doesn’t shout at you about this – I’ll see if there’s a way of making it do so.
