Luppp milestone: Timestretch!

Although its been a relatively quite period for development (due to lots of deadlines) today one of Luppp's long term goals has been reached: on-the-fly time stretching per track.

For the non-techie: This means that you can play a melody loop, and slow it down or speed it up, and the audio will remain in the same key! (No turntable RPM effect? Nope :)

Mandatory examples:

Although I'd call the quality "passable" is obviously not fantastic but there's some parameters in the algorithm that are available to tweak, so I hope to be able to improve it a bit a least :)

So when is a beta release?? Don't hold your breath, sorry. There's still some work to be done before Luppp will be ready for prime-time, but until then feel free to test it if you're interested!

Will keep you posted, -Harry

LAC performance

Hey All,

With the LAC on at the moment, its a prime time to do some extra development on features that need some finishing before being fully useful. That has been going on, and now the AutoMove feature allows the changing of the length of the fade. Currently the mapping to change the length is set to right click, that needs to be changed as we can only cycle up in length. Current options for beat lengths are 2, 4, 8, 16, and 32.

Also fixed was the "Master Beat Indicator", (the moving widget here). It now just syncs to JACK tempo, and will display which of the beats between 1 and 4 we're on. Since the AutoMove function is triggered on a downbeat (every 4th beat) the tempo indicator shows when the AutoMove fade will come into effect.

The current git head (master branch) is the exact version of Luppp that I used for the performance at the LAC Sound Night yesterday. Many thanks to Luigi Verona for his droning series which was the basis for the piece.

Greetings from the LAC, -Harry

Luppp : Scopes and Sends

New features have arrived in the devel branch:
-Interaction with the sends & return widgets
-Scope that displays the master output_W channel

Various code improvements have also been pushed along the way, be it that the headphones volume dial now goes up when you move up, or that that post-fade send now adhere's to the Mute status of the track.

Its another small step along the way! Mandatory screeny:

Luppp: New Feature! AutoMove

Over the last days a new feature was designed & implemented: AutoMove.

The idea is simple; in a live situation you just don't have time to write automation lines, not even simple ones! You also don't have a hand free to turn up your reverb during the next 16 bars, so what do you do? AutoMove it!

The following GIF animation of screenshots gives it all away:

There are preset automation lines, and widgets that are active get scaled by the AutoMove's value. You press one button, and it does the rest. Now we're making music :)

Available in the master branch as of right now!

Luppp: Alpha 1

Alpha 1 status:
100%  -  Closed



Today the last bug on the Alpha1 milestone has been closed, hence also the alpha1 release of Luppp 2.0. In a way this is a big occasion, its the first official release!

Alpha1 in action, with various effects and clips!

On the other hand, there's still a bucket load of work to be done before Luppp will be comfortable to use without various hardware controllers. I'm aware that there's lots of half-finished, half broken as well as broken stuff! Hey its still alpha!

Current milestone: Alpha2
There's already a list of bugs / feature requests up! There's also many GUI issues that are known and NOT there, but I'd prefer fix them than waste time posting a bug report.

Welcoming (adventurous alpha) testers, any issues will be dealt with as promptly as possible! Please file bug reports here: https://github.com/harryhaaren/Luppp/issues/new

Luppp: New Effects interface

After a "push" quiet period, I've just pushed up a couple of branches changes:
-Luppp's GUI has had a bit of work
-Effect control from the APC40 has been revamped
-Effects sends have been implemented

-The GUI now shows the effects under the track, in a small widget: reasons? Now you can always see the state of all your effects, not just the ones on your currently selected track. Better for live situations!

-The APC40 has 8 buttons under the Device controls, they now each map to Effect on/off. They're labelled for a different purpose, but I find this use quite intuitive.

-Post fader sends are implemented, including widget representing the state. The GUI widget doesn't work yet (ie won't change the value) but it does update upon a controller change.

I've pushed the changes to devel, but also the master branch, AFAIK its stable.

Luppp: Settling into Github

In the last couple of days the Luppp repo has made a new home on github, now complete with issue tracker & wiki.

The "manual" for Luppp will be constructed slowly in the Wiki part of github:
https://github.com/harryhaaren/Luppp/wiki

It currently contains some info on how to download & build:
http://wiki.github.com/harryhaaren/Luppp/downloading-building-installing

as well as a basic overview of what does what in the GUI:
https://github.com/harryhaaren/Luppp/wiki/Interface-Overview

Also new: A master "progress" widget that shows time into your 4 bars, or time till the next "4th queue" process, ie: Event quantization.

Read "When it goes from red to green, your Scene will change."

Fancy GUI suggestions welcomed, I don't really know how to spice this one up yet...

Hopefully in the next couple of days I can update it some more, and fix a couple of critical bugs that really hinder the use of scenes. More news soon!
