Hi All,
Just thought I’d post this rack for the B3-X that does the Leslie speed and brake using the mod wheel (CC 1) similar to the one I made for the IK Leslie.
Cheers!

I made another version, the first one was flawed. You just route your controller input route to the rack input and it’s output to the B3-X rack or plugin MIDI in. Sorry about that

Hi All,
I thought I’d add this rack for solo and performer that simply takes CC64 sustain pedal presses and converts them to Fast/Brake/Slow switches for use with B3-X. It automatically blocks the CC64 messages from getting to the Plugin and causing it to hold notes. If you like held notes, you would need to make other changes to accomodate it. It mimics the action of one of Hammond’s XK series foot switch options. You simply route through it on the way to the B3-X rack or plugin instance.
The rack changes color for each Leslie switch state for a visual indicator of each switch state …

Has anyone but me noticed that since B3-X arrived upon the scene, the other Hammond clones have stopped all updates? GSI and GG Audio both hinted upcoming improvements prior. Acoustic Samples made occasional, unannounced updates until the “new kid” entered. I normally check all their web sites and social media every week, but silence is all I find. Yes, I geek about the clones, but just find it odd there is no rush to compete as before. They all have good products, but when teamed with IK Leslie, they are outstanding. We’ve all proved it on this forum. I would only hope they noticed. It’s all about the Leslie.
End of rant…carry on.

I’m still enjoying the B3-X but this feature isn’t necessary with cantabile3. You can easily set up split point and transpose inside cantabile3.
I still wonder if I’m the only one who thinks that the sustain pedal behavior isn’t properly implemented.
A while ago I wrote in a different forum:
“If you hold a chord followed by pressing the sustain pedal and then release the chord and play a new chord with at least one note from the previous chord (while the sustain pedal is held) the notes belonging to both chords are missing as soon as you release the sustain pedal (while holding the accord).”
All other instruments (including organs) don*t show this behavior.
While the sustain pedal isn’t necessary to play the organ it could be handy when both hands are busy and I like to reach the ModWheel for leslie speed.
The sound is terrific, but it’s expensive and too heavy for my poor 4th gen i7
Hmmmm. I have no problem running it on my 8 yr old Toshiba Satellite even with other VSTs loaded. Did you follow Brad’s Glitch Free Guidelines?
Yeah, that doesn’t seem right. It does take a few seconds to load but it’s not a hog to run, or shouldn’t be.

Hi cpaolo,
You’re one generation ahead of my 2012 Lenovo X230’s (Ivy Bridge) and they run it fine. I remember someone here advising us to not use the built in rack style effects (as opposed to the pedals) as they seemed to be cpu hogs. The Leslie is the component that uses the most cpu in B-3X.
Thanks all for advises. First, I have a heavy optimized Windows, with lots of useless services and background programs disabled. I was mainly a hw&sw developer since late '80s, then PC-musician since 2002, so I think I have a good skill in “PC optimizing”.
At the end I discovered that I must set the B-3X GUI in background. This is because when the GUI is displayed, the GPU jump (randomly) up to 100%, stressing the CPU too, creating big glitches. In Cantabile I have a 18-25% of Time Load, that is the same load of my loved Ivory II Piano. So, playing those two together, load is about 50% so I have no enough room to run any heavy solo synth. I guess it’s a CPU limit, maybe a modern 8-core will work better (?)
Edit: At now I’m not plan to buy B-X3, still using old dear VB3
Well, I don’t use any of the rack effect. Anyway, I can’t run a Hammond with no Leslie.
If the Leslie is the component that uses the most cpu in B-3X, shame on IKm 
I see Corky beating me to it - the tonewheel emluation isn’t that cpu intensive but emulating the swirling goodness of the Leslie is more complicated. My 2012 Lenovo i5-3360 does both without breaking a sweat 
All the fx in the B-3X will spike the CPU load. As @Torsten said many times, he uses fx outside of B-3X, as the internal fx are cpu hogs. That also includes the fx inside the Leslie. Just the Leslie gain itself will make it jump.
There are several of us running lesser computers than you. That is why I suggested Brad’s glitch free book. I am not doubting your experience, but it’s not all about background services and disabling programs. There are more things to consider. What are you buffers size? How much RAM are you using? Are you using an audio interface? What driver are you using? What is the size of your drive? Is it SSD? There’s a lot of info we don’t have from your setup to try to help you use this amazing product.
I also have a long computer building and programming past that extends into the 1980’s. Still, there were many things I had to learn when I started getting into VSTs many years ago. When I came back to Cantabile, I learned even more from the many knowledgeable people on this forum. AND…I am still learning. Shoot us some more info…someone can surely help you get it going.

Corky
I am very close to finally pulling the trigger on purchasing this, especially since it’s on sale now. Is there a way to disable the lower octave preset keys? I can’t find a setting for it. I know a real Hammond is set up this way. It’s really easy to accidentally hit them on a larger keyboard. I guess I could just set up a key range in C3?

As far as I know, there is no setting for it.
That’s what I do. (For any organ, actually). Just map those keys right out of existence.
