Playing More Than One KB3 Organ at the Same Time (Dual-Manual B3)

I would like to create a dual-manual B3 setup but am having difficulty calling up the 2nd B3 program. How does this work?


In short, this cannot be done (with the SP4 alone- details below). KB3 organs are special in that they use an entirely different technology to generate sound - as such you can only play ONE KB3 organ at a time (i.e. B3 organs, #24-29 and those downloadable off our site). If you attempt to select more than one at the same time (i.e. splits/layers), the selection will not load (you will hear a basic piano selected on that channel in its place).

A few basic guidelines to keep in mind regarding KB3 preset use in multitimbral scenarios:

  • Only 1 KB3 program can be used at a time
  • When used in a Setup (split/layer combination) KB3 Programs should be used on zone 1/channel 1
  • KB3 programs consume a lot of polyphony, so are best used solo or in simpler combinations like a bass/organ split.
  • KB3 programs consume a lot of FX DSP so when used in combination with other sounds, they can often rob the other programs of their FX.

With the above in mind, any application requiring more than one B3 style organ would mean employing some sort of external sound source (2nd keyboard, module, VI) to handle the duties of the secondary organ.

With an external MIDI sound source connected to the SP4 MIDI OUT, such a Setup on the SP4 could look like:

Zone 1 - plays an internal SP4 KB3 sound

Local Prog:24* *any KB3 selection of your choice



Zone 2 (or 3 or 4) - plays an external B3 sound on an external MIDI device

Channel:2* *or other unused channel


Adding on to the above, per zone, you could independently:

  • alter the key range (LoKey and HiKey)
  • use Bank/ProgChg messages to automate the selection external sounds (MIDI Bank and Prog)
  • transpose a zone (Xpose)
  • set the volume and pan (EntryVol and Pan)
  • etc.

Be sure to see chpt. 8 in the SP4 Musician's Guide for details on Setup editing.
