Qtractor - A MIDI/Audio multi-track sequencer

Sending bus output to another bus input, but the receiving bus gets no signal/audio.

Forums

I've tried both methods, using the Qtractor connections window and also through the qpwgraph.

Currently, I'm using OpenSUSE Tumbleweed with KDE Plasma and X11.

I have Qtractor installed from the Geekos DAW multimedia:proaudio repository. The Qtractor version is 1.5.4, using Qt 6.9.0.

The issue is that when I send the output of one bus to another bus, the receiving bus gets no signal at all.

Apologies for my poor English. I'll try to explain as clearly as I can.

MIDI editor snaps back when manipulating note(s)

Forums

Greetings,

This is the first time I believe I've seen this behavior so I'll attach a few screenshots to help explain.

I have a clip I'm editing which begins at 5.3.000. The clip extends to measure 38 and I'm looping an area of interest as I tweak things. The MIDI Editor's Follow playhead is disabled as I don't want my view to change during playback. The 'midi-editor-1.png` screenshot shows what I have just described.

blacklisting a plugin doesn't seem to be working

Forums

Greetings all,

I'm seeing this message when starting Qtractor (not using a template).

lilv_world_load_file(): error: Error loading file `file:///home/windowsrefund/.lv2/stegosaurus.lv2/manifest.ttl'

The plugin in question is stegosaurus which I've compiled and installed. Installation adds the plugin to various locations under /usr as well as a single ~/.lv2/stegosaurus.lv2/waves/sine.wav file.

MIDI Velocity Adjust plugin with Qtractor [Solved]

Forums

Greetings, All,

I'm hoping one of you kind and skilled persons can help me figure out how to use the MIDI Velocity Adjust plugin with Qtractor. This was created by Robin Gareus, and is part of the x42 MIDI Filter collection.

The goal is to change all variable keyboard ON velocities from an Arturia Keystep MIDI keyboard to a fixed value, for use within Qtractor (an organ versus a piano). So, this would be global for the composition. I'd like Qtractor just to think it's connected to a plain vanilla keyboard, capable of only sending a fixed velocity for the notes.

Minor bug when recording audio

Forums

Hello again Rui.

I've detected what I consider to be a minor bug.

Steps:
1) Activate the record button in an audio track
2) Activate record in the transport
3) Deactivate record in the transport

An empty audio clip will appear.
The expected behavior is that nothing happens, just like the same process in MIDI.

Greetings

Possible error in offset correction

Forums


When recording audio, Qtractor performs an offset correction on the clip.
However, it is twice the current latency.
The correction should be equal to the latency.

It still wouldn't be exact, but it would be much closer.
I have verified this by entering the value by hand.

I have noticed this while doing routing tests to be able to record the session on a track dedicated to export.

Bug? with Fabla plugin

Forums

Fabla is the only DrumSampler plugin that allows me to encapsulate samples in presets.

The GUI gives this error in Qtractor. Carla opens the GUI correctly.
´´´
using block size: 512
FablaUI: Warning, host doesn't support resize extension.
Please ask the developers of the host to support this extension.
´´´

If it doesn't have a fix I'll use it without GUI. I just have to leave one instance preloaded in template, since if I load it from insert plugin it can crash Qtractor.
Presets can be made with a text editor.

Zero Copy

I've been doing some tests and I've been surprised.

If the session is from scratch, without templates: the sends between buses are done!!! However, they show the following peculiarities.
1) The Master Default bus only supports sending, not receiving.
2) The incoming signal goes directly to the track, it skips the fader and the volumeter. The output signal skips the fader, the volumeter works.

Similar problems were experienced during the development of the new AuxSend. Maybe there was a solution here too.
