Gotcha! I was thinking MP as a instrument… similar to an audio synth, thats why I make all those assumptions.

I guess the concept in LZX instruments is more like a Guitar or a Trumpet (in a video orchesta), rather than an Hardware with Digital Synthesizer (like Elektrons, TeenageEnginering, etc…).


#42

Yes, that’s the idea. Part of it is that Memory Palace is a component of a modular instrument, and we want the modulation interface for a modular instrument to be hands on controls, patch cables and voltage control! So the complexities of routing and so on, should come from how you patch.

We will do an Orion series standalone instrument at some point, likely a year or two from now. That will be a different context, and may be more like the video equivalent of an Elektron style synthesizer. For now we feel like modules are the way to go when it comes to the frontier of experimentation, opening up new contexts for use and multiplying possibilities.

@creatorlars (two part question)

  1. Can you output from MP’s DVI-D out, composite out, and 3.5mm RGB simultaneously?
    If yes…
  2. Can you output a wet signal from the DVI-D and a dry signal from the composite out at the same time?

#44

Good questions, @DesertMuseum

One more: Will MP’s a-to-d converter be the glorious resolution to all the complications of bringing SD footage into an HD world?


#45

wow that is fantastic news
I’m not sure if it would be something worth exploring but can it be toggled at video rates?

a happy medium that pairs a couple channels together could be nice too
opacity, hue, saturation, brightness
threshold, soften
delay, feedback
X,Y
rotation, zoom, stretch
or something along those lines

but then again there is something nice about the simplicity of global CV scaling


#46

Yes.

Unplanned feature, but possible with the hardware. The analog outs (RGB + CVBS/YC) will always be the same signal, but the DVI out could take its feed from a different part of the signal path and may be capable of additional resolutions. The real question is what you mean by “dry and wet” and why you want it. :slight_smile: We’ll let you tell us after you get a chance to play with it.

Probably not, but that’s part of the reason for the internal keyer and alpha channel (video rate key input.) The Opacity CV slider/channel are video rate analog as well (they sum with the alpha input.) So you can create a video rate effects mask with an external key, gate, or gradient, for video rate wet/dry switching.

a happy medium that pairs a couple channels together could be nice too
opacity, hue, saturation, brightness
threshold, soften
delay, feedback
X,Y
rotation, zoom, stretch
or something along those lines

That’s possible! The sections are divided up like this:
Opacity (modulation for the Alpha channel input)
Hue, Saturation & Brightness (related to the CSC: colorspace converter)
Threshold & Softness (related to the Keyer/Alpha compositor)
Delay & Feedback (related to the frame memory storage and its feedback loop to the keyer)
X, Y, Rotation, Zoom, Stretch (related to the DVE, digital video effects)

Most of the pushbutton features are related to the DVE, the others relate to parameter modes (auto-scroll, auto-spin, etc) and some are related to the buffer (clear/freeze)


#48

We’re focusing on 480i/576i resolutions right now, but will add HD formats and an upscaler for the DVI output if we can (the hardware is capable of it.) A lot of that has to do with whether or not we take a processing hit that in any way compromises the effects themselves. We’d of course love to offer multiple upscaler modes that can be tuned. All that said, the 24-bit RGB signal path and uncompressed memory/feedback of this device does things to SD video that are smoother and richer than anything I’ve seen before in the format. It preserves the beauty of the analog signals in a patch incredibly well, and that’s our biggest priority!


#49

Are there Settings/options that MIDI can tickle which aren’t available to modulate via CV inputs?


#50

No, probably not. We’re trying to avoid feature creep in that direction entirely. However given that there’s only a single trigger/gate input (which can be mapped to anything) you could probably have a lot of fun doing more complex sequencing of the pushbutton modes via a multi-channel MIDI trigger sequencer.

With this piece of hardware, we already have the core application running and looking beautifully – what happens for the next few weeks is implementation of all our stretch goal features. The priority for us is to push the hardware to its limits (providing maximum value to all of you, in owning a dedicated digital video platform) but those pushes will likely be in the area of maximizing the fidelity and latency of everything in the core applications rather than adding new features, unless it makes sense to do otherwise.

That display looks fantastic! Simple, E-Z to read layout. More and more psyched every time I get another glimpse.


#53

Thanks! We just finished making custom fonts today. This view shows the current version of basic parameter selection screens, but some pages will also have animated elements (that respond to the sliders) and we’re hoping to get full speed video preview going as well. The OLED really looks stunning in person.


#54

looks very nice thanks for sharing


#55

Is the soften circuit similar to edge feathering or even across whole image?


#56

That’s the edge softness of the key.
