Hymn voicing

I record my children playing their practice MIDI organ at home for when they cannot play at our Church. I take those 3 midi files, swell, great and pedalboard and use those recordings to playback at our church. I have tried and failed to get a good registration on Organteq 2 to suit our church acoustic and our bass heavy PA system tends to give a muddy playback.

Our best solution is to lean towards a flute based registration. The great is always playing broken chords to keep the choir in time.

Organteq has so many options that I can spend days chasing a registration that I think works but at our church does not. We are a Catholic Church in Perth Western Australia playing traditional and more modern Catholic approved hymns.

Does anyone have experience in using Organteq for hymns? Is someone able to assist with some suggested registrations please.

I face the uncomfortable reality of explaining to my wife, who is also our choir leader, that the investment we made in Organteq may not have been the sure fire answer I thought it would be.

Thank you for listening to me.
