Hi list, I'm playing around with a no-longer-developed java-based editor for Kurzweil syths called "VAST Programmer" (VP) and I have a question about MIDI on my Ubuntu Studio 14.04 in order to use a MIDI keyboard together with the editing software. My MIDI hardware includes: A Behringer UMX490 USB controller keyboard Kurzweil K2000R Synth Hammerfall DSP Multiface I. Editing with the VP, which works by sending and receiving system exclusive messages, requires that the K2000R's MIDI in and out are connected to the out and in of the Multiface. The UMX490 therefore needs to be connected to the computer via USB. Both the UMX490 and the Hammerfall DSP multiface show up in Qjackctl under the ALSA tab as both readable and writable clients. When VP starts for the first time it asks the user to select from a list of available MIDI in and outs. I selected the HDSP which is displayed as "DSP [hw:0,0,0]". VP then opens and allows me to edit the K2000. VP does not show up in qjackctl however and once connected to the HDSP I can no longer make a connection between the UMX490 (readable client) and the Hammerfall DSO (writable client) in order to play the synth. The HDSP seems to be fully occupied. It seems that I need a type of "MIDI merge" function to have the editor and keyboard functioning at once. I remember back in the 80s(!) little hardware boxes existed for this, but there must be a way of doing this software. Can someone please send suggestions? **** If anyone googles this and wishes to run VP on Linux, note that it was necessary to create the directory "/etc/.java/.systemPrefs/com" and make it user-writable with "sudo chmod 777 /etc/.java/.systemPrefs/com" in order to get it to run. VP can be downloaded from here: http://www.tangentcats.com/Downloads.htm To run, expand the zip file, enter into the main directory of the resource and enter: java -Xms256m -Xmx256m -jar "vastp.jar" You'll also need a "VAST" type Kurzweil syth connected via MIDI for it to run. There's a MIDI "Midi Compatibility issue" patch on the download page that didn't work for me - the GUI was sized strangely and unusable.
