I have used the trial version of Forte Dxi in Reaper. It does not appear in 64 bit reaper as stated above. It appears in 32 bit Reaper on win 7. The only thing is that the settings (assignment of sounds to midi channels) are not saved with the project...... The trial version is supposed to be fully functioning, so that is probably not the cause.... Still looking for a solution before I buy this plugin.
