Musescore going through Jack to VST plugins on windows

• Mar 5, 2016 - 04:39

Hi, I have been researching this desperately all night and need some assistance from someone who has already done this. I want to have musescore output through jack into some other program to load vst plugins to play instruments. I have fl studio and have been trying to get it to work with that, but I havent been able to. If anyone knows how to do this, or has gotten anything in the jack support on musescore to work, please let me know how you did it. I would ideally want to funnel the midi data from musescore to fl studio, maybe through an intermediary program that goes from jack to output to a generic midi controller driver so fl studio can pick it up as if what is being output fro musescore is midi data coming in from a usb controller. I am rather new on all this so any help would be appreciated.

Regards,
Davis

Maybe this video will help, but please note this is a development version, there are issues which need fixing in it.

That should be enough to get JACK set up on your system so you can playback MuseScore's audio through it.

To transfer the MIDI stream to FL Studio you will need MIDI loopback software - I recommend loopMIDI by Tobias Erichsen.

If all you want to do is play VSTi's then I recommend KXStudio's Carla application which is a JACK aware VST host which makes MIDI loopback software un-necessary.

If you need further help, come back here, I have successfully setup JACK on more than one Windows machine, although on one of them Sonar will not recognise the JackRouter ASIO connection, whilst the other machine is fine. I think this may be related to an incompatibility with Realtek High Definition Audio drivers, but I haven't definitely established this yet. There are ways round this if necessary, however.

Holy S*** I've done it finally! It works! I used the loopmidi program to route jack through midi to loopmidi, then fl studio recognizes it like a standard midi controller. However, I do have some issues.
1. When entering notes in note input mode, it seems the all the notes you enter get "stuck" leaving me with a synth that is playing all those notes at once. (this does not happen when pressing play in musescore, only in note enter mode), also after the song is ended in musescore the last note seems to be held down, keeping the audio playing until I go to fl studio and press stop.

2. When pressing play in musescore, the notes seem to be very jerky and immediately pressed down and lifted up. It would be nice if there could be a setting to have a interpolation with a very small time to gradually press and raise the midi notes so its not going from 0 to full force.

3. I do not know how to have multiple tracks with this. This may be that I do not know how to work fl studio as well as I should. But are the notes coming in from musescore in multiple midi channels or something? I'm talking about when there are multiple instruments set up in musescore.

I think thats all for now. I will experiment around with a bunch of stuff now because this is so damn cool.

Regarding #1 it could be that you are getting dropouts in the MIDI feed. These are known as Xruns in JACK jargon, and you can tell if you've had any by opening the Messages window. You will also find that the two numbers under "Started" in the Jack Control window will have changed from green to red.

If so you can try reducing frame rate, but apparently MIDI loopback software is prone to dropouts.

Not sure about #2

But regarding #3 yes MuseScore is outputting multi-channel MIDI data. There will be a different channel for each track in the Mixer, and you may have to increase the number of ports if you are getting more than 16.
