I am running Reaper through Wine on Ubuntu. I can import a music file and it plays normally. I then close that track.

Then I do: Insert -> Virtual instrument on new track... -> choose VSTi: ReaSynth (Cockos) This opens a dialog for FX on the track which I close. I then have a track which says ReaSynth. I then go to View -> Virtual MIDI Keyboard and a keyboard pops up. I press the keys on the keyboard and the levels on the MASTER track oscillate, and so does the levels on the control for the track1 (ReaSynth), but no sound is heard. The track is not muted. For the track I have the input on channel 1 and then i put it on all channels as well.

Am I missing something that must be set up?

This question came from our site for engineers, producers, editors, and enthusiasts spanning the fields of video, and media creation.

I had a similar question here. Maybe it can help you. – Friend Of George May 22 '12 at 12:44
Unlike most other things is Reaper, ReaSynth is almost completely useless. It's quite possible that you do get sound, but it's inaudible (e.g. too low frequency, to soft) because the synth is set up badly. Have you tried other VSTis already? – leftaroundabout May 22 '12 at 21:09
@leftaroundabout, that was exactly it! Could you post it as an answer? Why is it so bad, and what do you recommend as alternatives? It would be great to put that into an answer. – Vass May 29 '12 at 8:52
It's not bad, it's just very primitive. There are thousands of different synthesizer plugins, which are good for you depends on what kind of sounds you'd like. – leftaroundabout May 29 '12 at 11:18
@leftaroundabout, thanks, if you put that as an answer so I could accept it that would be great. and a few words on going about choosing a plugin would be also appreciated :) – Vass May 29 '12 at 17:51

I have just installed Reaper today, I loaded a vsti and selected my midi keyboard but no sound was coming out of it when I played but when I pressed record and listened to what was recorded I could hear the music. I noticed that there was a "Record monitoring" button (see the pictures below). I clicked it, pressed a key and I was able to hear what I was playing.

Record monitoring OFF

**Record monitoring OFF**

Record monitoring ON

**Record monitoring ON**
