velocity glides?

[metajack]

I recently watched some of the DCAM Synth Squad demo videos, and a few of the modulation options are quite interesting. Is there a way to do velocity glides in Zebra?

Another one that looked pretty interesting was sample&hold from another oscillator, which they show as being quite useful for making lo-fi sounds.

Velocity glide is super simple.

Matrix -> Mod: Velocity, Target: VoiceCircuit->Portamento


Can you post a link to the lo-fi sounds? I'd be surprised if Z2 couldn't make something similar.

EDIT: found it. . Watching now.

EDIT2: Hrm, the Lo-Fi might be tougher. I'd imagine Bazille could do this. Unless someone knows a clever trick to get S/H as a sound source in Z2.

The resolution knob can be used in a pretty S&H kind of way; try modulating the bandwidth OSC FX by a sine wave on LFO G1, for example.

Resolution can be modified via the ModMatrix too; in this patch MWheel -> Resolution, http://www.box.net/shared/9hlq68b7eb - it's a nice effect!

[e] The easy way to do S&H like this is just to use an LFO on Random/Hold.

[e][e] Oh, just watched the video. Isn't this just a heavily aliased sound pitch shifting?

This isn't quite what I meant, although this is also very interesting. If you watch the video below, you'll see what I mean. Basically the velocity is glided instead of the pitch. This makes for smoother transitions when you apply velocity to filter cutoff, etc.

I think one could do this by - rather than using velocity as a modulator, use an envelope with sustain set to full and velocity->scale to 100%, then tweak attack time, maybe even modulate that via velocity?

I see, that is interesting. Try as I might I couldn't come up with a way to do it. I tried using an env + individual vel on segments, but it didnt' produce the same effect. I also tried mmixers and mmapers to see if I could generate the lag necessary.

I'm hoping Howard or Michael read this and tell me I get a C on my synth homework but they tell me how to do it.

For pitched lo-fi create a noise source, put it in digital mode, set filter1 to 48, use key scale as the mod source with a depth of 48 (or is it 12?) and play with filter 2 for varying grunginess.

Bazille does this much better, you just use an audio rate osc for the clock source of a S&H and noise as the sample input.

Not sure about the velocity glide.

Wow, that's pretty neat! I tried 48,48 and 48,12. Neither sounded really in tune though. I tried both KeyFol and KeyFol2. Still, fast modulations of filter one do sound very similar to some of the zippery stuff they did in that demo.

I'm guessing 64 is the right value for the key follow. Mixing this in with normal oscillators is giving me great results! Thanks for this tip.

That seems a bit brutal with a noise source, though I had not thought to use the noise as input (I had tried it only as the trigger) and I didn't realize the oscillators could be the triggers.

I am now getting excellent results using Osc1 as the source, Osc2 as the trigger, and setting Osc2 to harmonics. That seem to be almost exactly what was done in the video.

Also, I found that the Quantizer gives kind of similar results.

That sounds about right. I don't have Zebra in front of me at the moment so I had to guess. I like to use the tuned digital noise as the modulator for the FM osc or an XMF. Very nasty results.

This is more brootal...

hit C3 then play with the fractal resonance on osc2, the quantizer value, the rate mod on LFO2, and the pitch/FM depth on osc1. Watch your ears on that FM depth.

I'm contemplating to add a lag option to the ModMixers. Thus Velocity->ModMixer/Lag = Gliding Velocity.

Cheers,

Nifty!

That sounds like it would be really cool. I also like the idea of being able to lag other modulators. You could do some neat things with pedals that way, building ramps instead of on/off switches.
