I made this really distorted bass, and just thought why not make a terrible quality camera shaking video to demonstrate it. A little bit of the quality is obviously because of the camera, but it really is very low-bit and dirty IRL- a bit warmer though.

That really is most impressive.

I've been able to copy your patch panel routing, you're obviously modulating the filters cutoff frequencies. and I've been able to get something vaguely like your sound, but would you be able to upload a nice clear still picture of your control panel (in Zoom mode, naturally), so I can see exactly what your settings are?

Have you tried routing the phones output to the input of the VCA and the output of the VCA to LPF in? Then if you route the mod wheel to the control input of the VCA you've got mod wheel control of the effect (or at least that part of it that is a result of the feedback loop to the LPF cutoff). Nice!

However, I don't see what the routing of the triangle output of the MG to the S&H in and the S&H out to the HPF in achieves that you can't achieve just as well just by using the MG as a modulation source.

You've got nothing triggering the S&H, so as far as I can see it's just a convoluted way of getting straightforward MG effects. (Or am I missing something here? It's entirely possible, as I'm still coming to grips with the patch panel. But I've tried it both ways, and to me they sound identical.)

Using the exact same routing you already have, if you route the square wave out from the MG to the the clock in of the S&H and wind up the waveform of the MG itself to about 9.92 then you've got sample and hold of the HPF cutoff frequency, but it sounds quite different from the normal S&H sounds you get using either the pink or white noise generator outs from the noise generator. I guess this is because it's sampling a Ramp wave rather than noise. (I'm not saying this is better than your current patch, it's just a variation)

We really ought to get some sort of thread going here for users to post their best patches.

Thanks for your post, it's given me a number of ideas I probably wouldn't have thought of without your stimulus.

I'll try to get a pic. Does the iPad have a screenshot function? It's technically not mine personally, and I haven't had much time to mess with it.

As for my whole S&H routing, I have no clue how to use it, I just kind of connected a patch cable there in hopes it'd modulate something, lol.

...

I think i overwrote the patch.

Alright, I tried to recreate the path as faithfully as possible. it's fairly close.

Just fyi, in the vid I'm pumping the iPad through a sub, so the patch won't sound the same unless you can too.

Here's the patch without your modifications:

Routing the mod wheel like you said and turning The LPFs EG all the way up can create some REALLY cool distortion.

From what I can see from your vid, your Sample & Hold isn't doing anything. You need something connected to that upper 'clock' input. This is a real sample & hold module. Not like the 'random' waveform that you get on the R3 which is wrongly called 'sample & hold' because it approximates the end result of the most popular use for the module.

What sample and hold does is it outputs the input value, only when the clock input is pulsed.
So for example you could have noise going to the input, and the LFO's pulse output connected to the clock input, and then you'd get that random stepped output like what the R3 has, at the rate of the LFO. It 'samples' the input every time the 'clock' input goes high (or crosses zero, depending on the implementation).

So if you think about it, you can use this for other sources too. I've always thought it'd be fun to use S&H with an EG to get a stepped EG. Or a ramp LFO at a different rate to the clock LFO, to get a pseudo-sequencer effect. Or try patching the 'phones' output into the S&H input or clock.

Also your patch into the LPF isn't doing anything because you don't have the 'EG2/EXT' knob turned up which would be the intensity from EG2, until you plug something into that socket (which you have) at which point it uses that signal instead.
Similarly the MG/T.EXT takes input from the MG unless you plug something into the 'total' socket at which point your patching takes over. Its called 'normalisation', where there are 'default' signal paths which you break when you plug something else into the socket. That's what the lines on the panel are for too.

Anyway, what I really wanted to say was that bass sound is awesome. I'm going to try and recreate it on the Radias and on my Legacy setup.
