Julien, Are you using 'whirl.horn.acceleration' in your config files? Actually, there have been a changes that break backwards compatibility of some config files. In Beatrix both acceleration and deceleration were incorrectly spelled with double 'll'. But note that the unit has changed, too. setBfree's 'whirl.horn.acceleration' is in RPM/sec. Beatrix' 'whirl.horn.accelleration' was in RPM per process-cycle (128 samples) The default speed of the leslie-drum has been updated as well - it's a bit faster than beatrix' original to match measurements made by Jonathan S. Abel and Julius O. Smith. They wrote outstanding papers on the subject and we are in direct contact with them. Improving the leslie emulation is on our ToDo list. Anyway, you can get the old default with 'whirl.drum.fastrpm=330.0' It is entirely possible that the sound is slightly different. The synth engine is no longer fixed at 22.05kHz, 16bit. We tried hard to preserve as much as we can in the process and retain artifacts when converting it to float; but it certainly is not bit-exact and there may be bugs.. Yes, please send us samples and point out differences that make you unhappy. Either upload them send somewhere or send them directly to me by mail. Will has access to real B3's and Leslie cabinets and already mentioned a few differences between the emulator and the real thing, too. I dare say we'll get there in time.
