Qsynth - Qt GUI Interface for FluidSynth

0.9.1 won't install a correctly made binary (patch enclosed)

Forums

At my site, `make install` (issued as root) stops with the following error, despite a successful build:

lupdate: could not find a Qt installation of ''
make: *** [Makefile:102: translations_lupdate] Error 1

This perplexing error message from `lupdate` seems to concern the provided translations (which personally I wouldn't use anyway).

Enclosed is a trivial patch for the Makefile to let `make` proceed with the installation.

I'm on Devuan Linux/amd64, GNU Make 4.2.1, Qt 5.11.3 ... more specs on request if needed.

qjackctl, qsynth and rosegarden with ubuntu20.10

Forums

I am having problems with playback in rosegarden.

qjackctl starts fine with pasuspender. I get playback in audacity via jack so I assume jack is ok.

qsynth seems to start up ok and qjack sees it and connects it to the system playback

But I get no playback from rosegarden. I initially assumed this was rosegarden selecting no port rather than the synth port but when I checked 'manage midi devices' in the rosegarden studio there is no synth port.

So I checked qsynths messages which after a string of straightforward messages end with:

reverb level control via MIDI

Forums

Hello. I'm using qsynth 0.5.0 and this function doesn't seem to be implemented. The GUI reverb control works but doesn't respond to CC 91 messages. All I would like to do is have different reverb levels for a couple of different instruments (on different channels), and it's too cumbersome to change the GUI control quickly. I thought about having a different fluidsynth instance for each instrument, with a different amount of reverb set, but as I understand it all the fluidsynths will receive the same messages so they would all sound on all channels.
