I'm honestly not trying to be argumentative, but this is literally the point of view that I was expressing in an earlier post...Urs wrote: Sat May 23, 2026 3:48 pm If people use our instruments with controllers that do not support Pressure or even Velocity, that is a choice they make, not ours. We're sad that people miss out.
The only reason I'm repeating myself here is because I'm not sure my point is getting through. When Timbre modulation is assigned via Controls A-D, because it's handled as a unipolar signal, the center position (50% of the modulation depth) moves the target parameter away from its original manually set position. But if I unplug my MPE controller, the Timbre signal vanishes, so 50% of the modulation depth also vanishes.Sound Author wrote: Sun May 10, 2026 10:54 pm If your controller doesn't have aftertouch, that's okay. You still experience the same patch everyone else does; you just don't get to hear what aftertouch does.
In this case, if you don't have an MPE controller with Timbre, you suddenly hear a completely different sound, especially if Timbre is assigned to something really noticeable like filter frequency.
This is a huge problem for sound designers who care about different users with different controllers hearing the same sound before they even touch their MIDI controllers. And this is why Ou_Tis and I have been hung up on this.
If the the manually set knob value was the starting point, then both standard MIDI controller users and MPE users alike would hear exactly the same sound when they open the patch, and that was my basis for suggesting that Timbre be its own dedicated modulation source because it would disentangle it from Controls A-D completely and they could remain simple unipolar knobs.
As it is now, I can't really use Timbre at all without producing a noticeably different sounding patch for non-MPE users, and to me, that's nothing short of a tragedy because it means that the only people who will hear the patch I actually made will be MPE users, and I have no reason to make sounds exclusively for a small audience of MPE users.
Zebra 3 is not the only synth that handles Timbre this way. I've had this discussion with other developers. Sometimes people ask me why I still haven't made sounds with MPE expression. THIS is the reason why. Timbre is such a cool thing, but because of the way it's implemented in almost every synth I've tried to use it with, I pretty much have no use for it, other than tinkering with it for about 20 minutes and then saying to myself "It's a shame I can't use Timbre in my soundsets".
