We recently added a PR300S and SOL to our 837. As a newcomer to midi it is taking me awhile to learn how to use the PR300S in the woship service. However, at this time I am focusing on how to implement the SOL with the organ voices. I have some questions I would like the discussion group to answer, if possible. 1. When you program the SOL voices with the voices on the organ, will the SOL voices you have chosen, stay with the piston you have selected? At this point it does not seem to work the way I though it would. For example: If Disk 1 is in the PR300S and I choose to use the Gedeckt voice on the Great (midi A), you must have that voice showing on the PR300S screen. I was under the impression that if you had the right disk in the machine the organ would know what voice to use from the floppy. 2. Can one control the volume of the SOL voices using the expression pedals? 3. I tried to set-up the reverberation on the SOL voices using the midi set-up controls on the 837. Unforunately, the change is only temporary. I have followed the instructions in the organ guidebook but it does not seem to work. I realize that the RSS does not work with the voices on the PR300S and SOL, however, a little bit of reverberation seems to help round out the sound of the SOL voices. I would like to say that many of the SOL voices blend very well with the organ voices. The variety of voices certainly enhance the sound of the organ. Any ideas would be appreciated.
