Have you tried using SWAM? Even without a breath controller, map your swell pedal to expression rather than volume, and it does an AMAZING job of sounding expressive if you use the swell pedal well with organ sound…

Watch GREAT organ players, and you’ll see them constantly ’shading’ the line, pumping the volume, all kinds of tricks to extract dynamics and phrasing from a line played essentially (in the case of strait organ sounds) with no velocity control at all! Just the swell pedal…

That and if your keyboard has aftertouch for bringing in the vibrato (about the only lack on the iPad version of SWAM is a delayed vibrato, so either a wheel or a mod wheel is essential) and you can just about pull off a great sax part.

Until recently I was playing SWAM saxes quite happily on my arranger, shading with the pedal. Lately I’ve moved it over to my keytar, which has a breath controller, and now I’m in sax nirvana…

Yes, I agree that Divisimate is more to set up than these ensemble features, and I commend Yamaha and Wersi for making it simple, but it’s still the way that, once split up into the individual parts, the inter-note behavior is what makes the parts convincing.

Most modern arrangers have some articulated horn sounds, and in lieu of a proper modeled sound can still do well. The combination of ALL articulated horns and the ensemble feature should be quite convincing!

But… as I’ve said about many different sounds (guitars especially) getting a convincing emulation is still 90% about wrapping your head around what is typical idiomatic voicing and phrasing. There’s no reason an organ player can’t do that any less than a synth player or a pianist or even an arranger player!

Just listen carefully to the voicings, and listen carefully to what the player does, and even more importantly what he NEVER does, and with a bit of time and practice you’ll be able to play horns and guitars well enough to fool a discerning listener..!

What I try to do is immerse myself in the instrument and style for about a month. Listen to nothing but sax players for a month (give Bird or Trane a miss until you’re more advanced! 🎷😂) and play ONLY that sound when you practice, it sure speeds up getting your head around the typical lines. Record yourself constantly, listen critically and try to note what you did when you broke the realism and never do it again! Note where you really nail the idiom, keep doing that!

A month of anything without cutting to something else occasionally will quickly get you up to speed. Horns, guitars, sax, string voicings, anything non-organ/piano in technique will come a lot less painlessly if you steep yourself in the sound!
