This would make it easier to draw a new configuration without worrying about a) playing two slices at the same time or b) having a column without a slice (i.e. one slice, not more or less).

libsndfile doesn't support mp3. At least not the standard version of libsndfile. TODO implement minimp3 by lieff.

fork in unwanted for audio applications.
related lsp-plugins/lsp-plugins#54

Carla tries to prevents plugins from calling fork under certain conditions.
Resulting in not being able to open the links in this plugin.

Carla prevented a plugin from calling 'fork', bad plugin!
sh: 1: Cannot fork
BJumblr.lv2#GUI: Can't open https://www.youtube.com/watch?v=DFSi7TMqvMw. You can try to call it maually.

When running the plugin in Carla 2.2, it gives me a cpu % of 64 in htop (reasonable modern cpu with 4 cores).

The division of the grid in fours is visible via color differences (blue vs black), but that could be a bit more clear imho.

Fun project for sure!

Not sure where this is coming from, but when I start jack_link, BJumblr in Carla produces corrupted/distorted sound.

I think I'd need to restart JACK to get normal sound again.

Enable user to select between:

• Vertical progression (progression from bottom to top, sample/stream from left to right, horizontal progression line, vertical playback lines)
• Horizontal progression (progression from left to right, sample/stream from bottom to top, vertical progression line, horizontal playback lines)

See screenshot below

I have nowhere to click to go up a directory, or home, or root.
I am locked out from selecting any files.

Also note how no folders are visible either..

Using v1.6.4

When you've it set to 32 steps, the overview is nice and good. When the setting is 16 steps, the canvas is large, too large imho, I don't have a pleasant overview. Might be nice to be able to zoom in/out somehow.

Would be nice to be able to save presets, that's only possible via Carla 'save as'?

At present, B.Jumblr is a pure live audio stream slice re-sequencer. What about a non live-mode replaying and re-sequencing "static" samples? Samples could be imported from the live audio stream or an audio file. What do you think about ?

Requested today by @unfa in his youtube livestream (https://www.youtube.com/watch?v=MmGLTOkNenc):
Store multiple patterns in one instance of B.Jumblr. Add a control port to select the respective pattern. This should enable automation controlled switch between the patterns.

Getting this atm;

Error making: bjumblr.lv2-git

Allowing playback to be controlled manually by having two control inputs, one that on a 1 input triggers the advance of the white line and the playback of the sample in the new column, and another that triggers repeats the playback of the same sample.

Whilst I'm mentioning a trigger mechanism, it might be worth my suggesting that the use of CV rather than control could allow for trigger, gate, and modulation of the amplitude of the signal, though that would be a whole other level!

So that if the user finds that their loop is not in sync with the music that is being input, they can press the reset-to-first-beat button and the left-most column gets started from that point?

(A related feature suggestion with similar but different functionality that it might be worth mentioning at the same time: to have -1 or +1 buttons, so as to shift each columns samples a column left or right? That would not change the start time of the samples/loop though.)

To accommodate other common rhythms and time signatures.

Show FileChooser I/O error message box in addition to std::cerr

How about being able to set the pitch of each clip? Give each pitch a colour and use some mod key + mouse scroll to shift that up and down for each sample box?

contains int but NOT bool.

I compile bjumblr on Fedora 32 (the last release).

Not sure whether this is a BJumblr bug or a Carla bug (cc @falkTX )
But when saving a session, closing and re-opening the session in NSM, the loaded sample in BJumblr isn't restored.

For being able to quickly take the effect in and out of the mix.

It looks like sometimes B.Jumblr run out of sync as seen in this youtube stream https://youtu.be/MmGLTOkNenc?t=5319 by @unfa. Confirmation and further analysis required.

When working with it, you start to think about the option you'll find in non-sequencer. Most notably the phrase editor, where you can arrange and play the made patterns in a certain sequence (to make a song / beat).

But in this case you probably want just one pattern play at once.

Hm maybe a combination of the Phrase Editor and the Pattern Triggers. Some way to be able to sequence patterns. With the ability to repeat a certain pattern multiple times. 4x pattern 1, then 4x pattern 4 .... 8x pattern 2...

... or alternatively rotate waveform by -90°. This makes it easier to see which part of the sample or stream is on the turn. A selected pad will directly (and also visually) represent the part of the sample/stream to be played back. Also as result the white line will go from up to down.

You maintain the WWW_BROWSER_CMD, see here: https://github.com/sjaehn/BJumblr/blob/master/src/BJumblrGUI.hpp#L75

It is much easier to just launch xdg-open https://www.site.com in order to open it in the currently default browser.

I've noticed that sometimes I do enter new 'notes' accidentally. Like my mouse mousebutton is stuck, but it isn't. Using the latest version in Carla.
