	Hi, sharing experience: My wife needed to make some audio work for a video with Reaper on a linux box. Reaper runs in linux under wine using wineasio and jack very well, but I could not get the video playback working in reaper. Quite a hack, but a workaround I got to function very well was: 1) Reaper can send out OSC messages about its actions. To enable it you need to describe a OSC configuration file in REAPER/OSC folder - copy file Deafult.ReaperOSC to something else and describe the lines, on which actions the OSC messages will be sent (or received if you want to drive reaper from outside). In my case just one line: TIME f/time # send time as floating point value in seconss on path /time Go to Predernces->Control Surfaces->Add->OSC and select the profile (the file ) you saved and the ports and addresses you want to use. 2) to play the video I used xjadeo that can be driven with the jack transport 3) to pass the reaper time messages to jack I used a small csound file: -+rtaudio=jack -odac:system:playback_ -d -m0 sr = 44100 nchnls = 2 0dbfs = 1 ksmps = 32 giHandle OSCinit 9009 alwayson "osc" instr osc ktime init 0 kflag OSClisten giHandle, "/time", "f", ktime schedkwhen kflag, 0, 0, "jacktime", 0,0,0, ktime-680 ; the music in reaper starts at 11:20 endin instr jacktime icommand = p4 itime = (p5<0) ? 0 : p5 jacktransport icommand , itime endin Xjadeo can receive also OSC messages but the format how reapers send its time does not fit with what xjadeo expects (SMPTE or time in video frames). The same way reaper can be synced with other jack-aware software like hydrogen, qtractor, jamin or whatever. Hope it turns useful to others as well! best! tarmo

	Nice hack. One of the things I like so much about Reaper is that it's quite easy to extend its functionality. For a piece of commercial software it really provides lots of ways in which users can easily extend its functionality.

	Thanks also for the report about how to run Reaper under Linux, I had been wondering about that. Does running under wine affect audio latency or processing load? best Oeyvidn 2014-03-02 16:15 GMT+01:00 Rory Walsh : > Nice hack.

	You can also use Ardour to do this. In fact ardour will automatically sync up with xjadeo. www.peimankhosravi.co.uk \|\| RSS Feed \|\| Concert News On 2 March 2014 15:10, Tarmo Johannes <tarmo.johannes@otsakool.edu.ee> wrote: Hi, sharing experience: My wife needed to make some audio work for a video with Reaper on a linux box.

	Yes, sure, I use ardour, but my wife is more used to reaper. Oeyvidn, yes, of course wine adds some extra CPU load and somewhat latency but it is not noticeabble to me. It runs really very nicely if you are not doing too heavy things. tarmo On Monday 03 March 2014 09:13:41 peiman khosravi wrote: You can also use Ardour to do this.
