Hi All - I bought GPO 4 a month or so ago & have been trying out all kinds of stuff with the instruments on REAPER. I have read the Garritan Manual, and a lot of the REAPER Manual, but I still have a couple of problems: I can assign multiple instruments to one ARIA player but I'm not sure how to set this up within REAPER. The only way I can seem to have several instruments playing at the same time is to put each one on it's own ARIA player - so I end up with several images of the player onscreen at the same time - which is probably crazy? If anyone could outline the best way to do this or point me to the relevant page in the REAPER Manual I would be really grateful. (I am a complete beginner so all the technical terms & procedures are very new to me at the moment).
-- right-click in the TCP area below any existing tracks -- select "Insert virtual instrument on new track" -- select GPO 4 -- click [Yes] on the "Build Routing confirmation" window; that will create tracks for all of the audio outputs from GPO 4, -- open the FX window for the GPO 4 track (click the [fx] button) -- select [Options] >> "Build 16 channel of MIDI routing to this track" Now you will have 16 tracks sending MIDI (on channels 01 ... 16 respectively) to GPO 4 and several tracks for the audio outputs from GPO 4. Within GPO 4, load your instruments and set the routing for each one - receiving MIDI on a particular MIDI channel AND sending its audio to a particular audio output. Back in Reaper, name your MIDI tracks for their destination instruments and add the MIDI. Job done. Much more info is here: If I ever buy an ARIA Player product (tempted occasionally) I might do a walk-through.
I don't have GPO 4 so cannot help you there. I would think that its User Guide covers that. What you are aiming to do is get each loaded instrument to "listen to" MIDI on a different channel and to send its audio out to a separate output (so that you can mix it and add effects to it separately from any of the other instruments) Edit: ^^^^ Found the details in the ARIA Manual Reaper: --to name any track - double right-click the name area in the Track Control Panel (yes, it's not the most intuitive key combo) -- to insert an empty MIDI clip - Ctrl_drag the mouse in the track where you want the clip to be - remember that the first MIDI track that was created sends out MIDI on channel 01 and the last sends on channel 16; that way you can name each track for the instrument it triggers in GPO 4.
