Subject:Re: VR-09 Leslie problem

So I'm sitting with my VR-09 playing it through my Yamaha mixer and my QSC K10's, and there is no question, if I disconnect the (R)ight channel, the default leslie just loses a lot of the low rotor sense of motion. The fact is that I would expect this since what we are trying to simulate is by it's nature a stereo effect! That said, when I disconnect the (R)ight channel of my Mojo to listen to the Mojo sim in Mono I can hardly hear the difference (that says something about the quality of the Mojo sim).

So yes there is a significant difference between the VR-09 leslie sim in stereo vs mono... ! As To B3 pointed out the leslie sim really sounds antisceptic in mono.. and to my ears the low rotor has much less sense of motion.. AND one of the things I noticed is that the low rotor sounds like it goes around, stops, and then goes around again, then stops, and goes around again.. (I noticed this before but it's even more prominent with the sim in Mono). It just doesn't sound like it's going around smoothly.

So here's what I did to improve the mono sim.. Take the stock Hammond sound (by just selecting organ), and change the MFX to twin rotary. Increase the twin rotary to the point where the slow rotor has more sense of motion.. I found that the 12:00 o'clock position worked for me) and give that a listen.. Now there is much more of a sense of motion now and it's much less antisceptic sounding.. Now the down side of this is that the tremolo speed has a tiny bit of phasing, AND if you're using C3 it sounds kind of crazy.. so I back off the Chorus setting.. for example I normally like lots of chorus and use C3 chorus but IF I was playing in Mono, I would probably add the twin rotary, and drop the chorus to C2 or C1 so the tremolo/chorus combination isn't too freaky..

Give that a try.. and try different combinations of Twin rotary AND Type1 or Type2 rotary sims.. ALSO try turning off the regular rotary sim, and just listen to the twin rotary by itself.. by itself, and in mono, the twin rotary sounds very antisceptic, but it's interesting to know the nature of the effect that you're adding. Also set your leslie speeds to your liking, but do so within the context of the twin rotary sim.. the twin rotary effect has fixed speeds and ramp up/down times, you can't change them, and there are rotor/horn speeds that work well with the twin rotary and some that don't.. but that's a matter of taste.. Personally, I always like the slow rotor to be turning very slow and the ramp up/down slow as well.. To me it gives the sim more of an authentic sound..

Bottom line, I think you can improve the mono leslie sim by using the twin rotary effect as an MFX effect on top of the basic leslie sim. Give this a try and let me know what you think..
