Convert Yamaha operator output to EFM Volume

Holyver	Posted on Thu 17 Feb 2022, 02:37 PM Hello, I'm trying to convert some of my Yamaha TX81Z patches to the EssenceFM, to see if I can live without it, and just keep the EssenceFM. Is there some kind of conversion table/chart available that maps yamaha FM operator output levels to EssenceFM operator volume levels, and preferably feedback levels too? Currently doing it by ear, but that is a bit hit and miss. Since it can read DX7 patches, the data must be available for that one I would think? That could be a good starting point, because I think I've seen articles comparing DX to TX parameters before. Thanks in advance!
KODAMO	Posted on Fri 18 Feb 2022, 01:22 AM DX7 volumes are more exponential than on the EssenceFM, the middle value of the DX7 (50/99) will be very quiet compared to the middle value of the EssenceFM (64/127). <img src="https://kodamo.org/download.php?id=151" width="500"/> Green looks like the DX7, blue is more like the EssenceFM (this is just a random pic to illustrate the difference, not actual values) In the DX7 import system we guessed the values by ear using a formula. It's a bit tricky, since volumes also need to be scaled depending on Velocity Sensitivity. Best may be to find a way to convert TX81Z patches to DX7, then import them on the EssenceFM, or do everything by ear.
