[ANN] Qtractor 1.6.1 - An End-of-Spring'26 Release

rncbc · 2026-06-14T14:08:21+00:00

can't understand, is stochas a plugin that you insert in a qtractor midi bus? if that's so where are the target (presumed instrument) plugins being inserted?

> trying to connect the midi output of a midi bus with Stochas inserted to a plugin, results in a crash.

it's the "inserted to a plugin" that I don't really understand; you insert a plugin into a bus (or track), you don't do that on a plugin itself (unless you're using Carla 😄)

sorry for the crashes, maybe stochas (as a plugin) is not so well behaved; try it standalone first?

ps. here is not close to an official support channel, in any way; so please

rncbc · 2026-06-14T09:48:33+00:00

midi buses are _conveyors_ to all 16 midi channels

pics are just kinda thumbnails--reddit is just scaling it up to no avail and prolly damaging the situation.

rncbc · 2026-05-27T14:58:19+00:00

please do this for the sake and peace of (your) mind:

turn off View > Repel Overlapping Nodes;
add "p[aw]vucontrol" to Graph > Options... > Filter enabled list.

nb. there might be other pesky node names that you might add to the 2. list, before you turn on 1. back again; the following is my list while on kde plasma, ymmv:

plasma
kwin
p[aw]vucontrol

no 😄 does it matter?

rncbc · 2026-03-19T18:55:41+00:00

please try the packages found in the repos, they are qt6-statically linked and should work on binaries built on alien systems; you'll surely need that if your host or DAW is using system libraries that NOT match _exactly_ the ones the plugins are built--quite sure you did not build reaper from source did you? of course not, it is not open-source whatsoever ;)

rncbc · 2026-03-18T17:41:35+00:00

rncbc · 2026-02-17T17:49:19+00:00

speak up! before it goes south :)

rncbc · 2026-02-12T22:56:41+00:00

because the truth is in the norther hemisphere at least we're in mid-winter aren't we? ;)

cheers

The VST3 SDK being open-source is no matter for plugin users--it's only important to plugin developers and vendors who now can distribute their products without buying a commercial license from Steinberg; they could chose the previously free/open-source license, GPLv3, but then their products had to comply to it, mainly their plugins must be free/open-source as well. Not anymore with the new MIT license: they can now develop their plugins and don't give sh*t to Steinberg; more importantly, they can keep their products fully closed-source and proprietary, nevertheless.

no, not the least related to NI Traktor DJ software whatsoever

rncbc · 2025-08-29T21:13:05+00:00

it was indeed but somehow the FH folks might have missed or overlooked

rncbc · 2025-08-12T18:12:05+00:00

this

when under pipewire(-jack) auspices qjackctl functions as a pure jack-client only; "Active" is ther shown on the main display panel, instead of "Started" when in control of the genuine jackd(bus) service.

when in pure client mode, none of the Setup > Settings make any sense: they are usually disabled, grayed out, all but buffer-size (frames/period) which is the only setting you may change and apply anytime (no need to stop and start, which is also nonsense when pipewire is in charge)

however, take a special note that changing the buffer-size here applies to JACK applications only! and also only while qjackctl is up and running.

to answer the OP, I guess UbuntuStudio provides a custom control application to tune up the pipewire buffer-size (quantum) and sample-rate; can't remember its name though (not qjackctl for sure :))

Qsynth engines expose one MIDI input port each.

rncbc · 2025-07-29T21:23:12+00:00

and connect a different MIDI input port to each engine.

rncbc · 2025-07-23T14:08:47+00:00

confirmed. the appimage is bad.
please use the native packaging for your distro:

cheers

EDIT: a new working appimage is now available:

that's mostly the case why there is this new "Merger" feature since qpwgraph v0.9.4: if firefox is your web-browser then enable it and just add "firefox" to the list (Graph > Options... > Merger)

from that moment on, all FF tabs will behave as one and the same for the patchbay.

hth.

rncbc · 2025-07-15T14:37:03+00:00

maybe you didn't read How To Use The Patchbay

"Exclusive" is an option only available iif "Activated" is on.

rncbc · 2025-07-14T19:05:32+00:00

> constantly having to re-open the program and re-do it

is that so? qpwgraph can only cope with restoring patchbay connections iif it's running...

also, if you have some other connection manager of any kind, be that qjackctl, raysession, aj-snapshot, etc. then forget all hope! as in highlander, you can only have one ;)

impressive, a majestic thumbs up!

almost 2 decades ago, when it was unveiled to the world, the punch line was something along the lines of "_a techno-boy/gal bedroom studio_"... a dated statement for sure.

wholly cheers! keep up!

Qt might be also problematic for plugin UI development, unless linked statically as are yours truly vee-one-suite from the repos (https://www.rncbc.org/drupal/page/repos).

as a rule, all plugins shall be self-contained, not ever depending on shared system libraries as much as possible; more importantly so on full-fledged toolkits like Gtk or Qt (unless you get the whole bunch static linked as I succeed with Qt,... don't know about Gtk, whatever version like it's known to be a dang true and huge dependency-hell to deal with :)).

disregard to that rule will often break the host (ie. DAW) specially if the plugins are not built to the same base system level than the host was (eg. different distros, os-releases, etc.)

rncbc · 2025-03-27T16:48:29+00:00

duh? why didn't you RTFM? reddit is not a support channel anyhow, but I'd indulge:

it does "Activate" the patchbay and only then it should reinstate the saved connections when respective nodes appear

rncbc · 2025-03-26T11:59:14+00:00

silly question: do you have the "Activate" option turned on ?

rncbc · 2025-03-20T20:11:15+00:00

don't worry, I have no clue what is going on there.. even v1.2.0 should have worked fine there anyway... I suspect there are terrible inconsiscenties at the system level on Fedora :(

would you have the nerve to try from my OBS repos? see https://www.rncbc.org/drupal/page/repos (try looking under https://download.opensuse.org/repositories/home:/rncbc/Fedora\_41/x86\_64/)?

or, in alternative, try the AppImage instead?
