I'm currently working on an envelope generator that has multiple chain-able segments. It also feature a curve control which allows you to adjust from linear to exponential. I have it working, but I'm still trying to get the curve control logic a bit better. Should have something soon.

Ok, here's the simple version.

You ping this module with a trigger and it plays the automation on the spline. If you draw a pattern like the one in the video you can use it in the same way.

However, trying the patch out on the iPad I was reminded why I don't often use the spline node, placing points at the edge of the spline area can be quite fiddly. So creating gates that start and stop on the grid can be a slow process when making a complex pattern

To mitigate this, I added a multiplier to the period, so you can combine two of these pingable splines at different ratios and make a new pattern with increased complexity that still goes to a beat. I attempted to make a demo showing what I'm talking about.

@futureaztec I'll be happy to make revisions if you find something you think can be improved.

@stschoen that's awesome, let me know when you get the curve control figured out. You can see from the video above what I would like to achieve.

I was using a midi note every 4 beats so I could perform a reset on other patches, like DFAM DIY. And I was using a midi note every beat so that I could generate a tap tempo for clock. This way the patch would be perfectly in sync with the daw. Not that this is the best way, just the first way I learned.

So how do you sync the gate module with the DAW?

Also, what is the function of the trig input?
What is the function of the loop switch?

I suppose period is a reading of the length of time that the gate performs the modulation from point start to finish?

I used Cubasis because it seemed the simplest for what I was doing.

>I was using a midi note every 4 beats so I could perform a reset on other patches

Does Audulus receive midi when used with inter-app? I thought was one of the things that was missing from the plug-in version and one of the things that will be addressed in the upcoming plug-in overhaul. Although I'm not sure what has be fully promised, to be totally honest.

>So how do you sync the gate module with the DAW?

Well, you have to be clever, I suppose. There are two tracks going into audulus if you hard pan two incoming channels, and you can use one as a click track with a kick drum and use that like a trigger. I have used this technique with Korg Gadget and it works well if you run the kick into a envelope.

>Also, what is the function of the trig input?

You send in a gate and it will trigger the spline automation

>What is the function of the loop switch?

The loop switch causes the module to trigger itself, creating a loop. You can toggle the button or you can send it a gate, this is so you can create more complex patterns.

>I suppose period is a reading of the length of time that the gate performs the modulation from point start to finish?


The period is a number with the unit of seconds. That is why it has a little hashtag on the input.

Here is a quick guide on input notation:

blank - this is audio or modulation input and would like a signal between -1 and 1
green light - gate signal (occasionally envelope out)
o - note input in Audulus 1/octave system, similar to the modular volt per octave system.
# - this is a number input and can have any unit, but is often a length, a speed, or a decimal code.

You can make a module that calculates the period you hold down a gate for, if that's how you want to make it though.

>I used Cubasis because it seemed the simplest for what I was doing.

Oh yeah, it seems like a great DAW. I just seem to have bonded with Korg gadget, so I haven't felt compelled to learn the intricacies of it yet.

Cool! I guess I never know that inter-app audio worked between Audulus and Cubasis, because it doesn't when you have an ES-8 plugged in. Today I leaned :)

You have your gate signal connected to the multiplier knob and not the trigger input. You want to have that knob set to 1 because you want your period to be around 1 bar of your track. If you want two bars you set it to 2, etc.

I made a patch that should sort it out. I added a module that calculates the periods between re-trigger pulses. You should be able to load and it should just work.

I just posted it? Perhaps you are viewing the forum with the mobile version? The patch should be attached on my post.

AH, now I get you. Well that was definitely the first time I used Audulus like that for an iOS DAW. :)

Makes me look forward to the midi/plug-in overhaul.

>Can this patch be beefed up in any way?

Certainly! But I think it's definitely up to you how to best implement those changes, the patch I uploaded was just my take on how I would achieve complex results. Feel free to use those other modules in your patch in new ways :)

>"The West Coast LPG represents the Blocks take on the low pass gate, a peculiar filter circuit originally designed by synthesizer legend Don Buchla for controlling the dynamic properties of a sound. It uses an optocoupler that smoothes the LPG's response to external control. When excited by a sharp-edged signal via its Pluck input, the LPG opens and closes in a natural sounding manner, giving sounds a plausible quality that is reminiscent of a drum hit or a plucked string."

See the attached patch, that's what I have been using for plucked LPG sounds in audulus. I think the only thing it really lacks when compared to my euro rack LPG is a dampening circuit, but I would say it's a fair replica.

>It would also be nice if spline had a snap to grid function and I am looking forward to what @stschoen said about curves.

Don't you worry, if @stschoen is taking his time, it's only because it's gonna be good. You should check out some his modules for plucked filter sounds though.

@stschoen Does this mean no spline curves?

Ahhh the familiar colored boxes of Cubasis. This module looks interesting. I'm looking forward to playing around with it when I get the chance.

I'm glad you are enjoying the pingable spline :)
You are looking to trim the modulation? Find it in the Module Library>Utility>Modulation>Modulation Attenuate-Offset.

Yeah it's easy to get carried away! Especially when you uncover one of the many worlds of infinite possibilities within Audulus. But at the end of the day, all that really matters is the sound, and a little trim can mellow a raw idea into something worth listening to.
