G'day Thomas. This is one workaround to the problem on the XM-1. The XB-1 does have a dedicated brake button, with brake time perameter in the leslie edit section. I believe that this is identical to the XK-2 Leslie sim.

My father has the XM-1, and we compared the sound of the 2 clones. When running through the same amp and speakers, there was a noticable difference in the 2 leslie sims, even after all perameters were matched for an accurate A/B test. We both felt that the XB-1's sim was warmer, and the upper rotor sim was sweeter and more authentic.

No, the XB-1's Oscillator phase continuity parameter is independant to the tuning mode. Going from memory, the tuning mode is the replication of the fact that a real B-3 runs slightly sharp (7 cents?) due to Hammond not being able get the run motor/gearing etc. on perfect equal temp.

I'll supply you with another envelope if you want :-)
