Bi Polar or Uni Polar: Zebra

[tconrardy]

Just curious. Does Zebra use Bi polar modulation, or Uni-polar modulation? Looks like it uses both, but not quite sure.

Most modulators( Env, Lfo)seem to use Bi-polar, meaning the default point of the knob is in the middle position and the modulation goes from neg to pos ( depending on the middle knob position) However for MIDI things like aftertouch, velocity, keyfollow, ect. These seem to use Uni-polar, meaning it starts at zero position. There is nothing in the manual about bi polar or unipolar settings however, so I am really curious.

Hi Tim,

Actually, only the LFOs and KeyFollow are bipolar. Oh. And the ArpMods.

Envelopes, Velocity, Midi, are unipolar.

ModMatrix/ModMixers naturally take up the bahaviour of things assigned to them.

LFOs will at some point in the future have switches for unipolar modulation.

Hey Tim

...meaning the default point of the knob is in the middle position and the modulation goes from neg to pos...

Just to add to Urs' post: As you probably noticed, there's plenty of the above, regardless of whether the actual mod source is unipolar or not.

Thanks for the great answers...just trying to understand the concept, as it is kinda new.

I noticed something this evening when using CC messages to Z2 and FSVA.

If I map some controllers, change a preset, and press "snapshot" on my hardware controller, the mapped values don't jump. They only move until I've moved (changed) the mapped CC controllers. I'm guessing it's something in the internal makeup of how CC messages are processed when received.

Yes.

CC messages that are within the "incremental" range (what did we say? 54-74?) are processed as incremental unless a value beyond that range comes in. Then they switch to absolute CCs.

If that's yet another problem within the implementation... d'oh... not they easiest to overcome but you'll need to be patient until the MidiCC total overhaul

Sounds good, I know you're a one man show. I guess I'm just documenting everything I find that's not traditional behavior and I'll let you decide what goes in and what doesn't. I'm working on hacking a midi controller to add in joysticks (for the pref panel) and noticed when I sent the snapshot they didn't move. And since joysticks have limited travel, I can't convert them to rel-cc messages.

Thanks for the reply.
