But that stil leaves only 2 modules that can do 303 type slew.

The ADDAC 209 and WMD Time Warp.

Are there any more?

First of all, as I mentioned, I understand why you'd not want to do it the complicated way. I'm treating it like an experiment to see if I can learn what a module does.

Here's what I used

1 a bipolar mixer for the subtraction Triplatt
2 a DC coupled ringmodulator. Boundary
3 a shift register. Maybe I'm wrong here, but I added an offset and treated that as zero point.
4 a CV controled slew limiter. Boundary

Hoi Stef,

That's exactly what I've come up with.

Here I've not added cv control for the slew, but that's trivial.

I was able to do it today with a second module to manipulate the rise time based on pitch. But I understand now why you'd want a module for this. Thanks for sharing.

Hoi Stef,

I've been thinking about this.

The larger the note difference the faster the slew.
So you need to subtract the 2 note values.
That gives a problem, because you can get a negative value.
To make all these values positive, you need to multiply that signal with itself.
A^2 (a squared) is alway's positive.
You can do that with a DC coupled ringmodulator.

On top of that you need to store the first note value, or else you can't subtract the second note value, this can be done with a analog shift register.

So you need at least 3 extra modules and a CV controled slew limiter.
1 a bipolar mixer for the subtraction.
2 a DC coupled ringmodulator.
3 a shift register.
4 a CV controled slew limiter.

It get's complicated fast.

One other tip:

Digital modular synths are great for trying out stuff, without costing much money.
VCV Rack is free.
https://vcvrack.com/

There you can do lots of stuff and find out what you want.

My own live techno improv stuff here.

It's 180bpm, so not for everyone.

Hi everyone, I'm a beginner to Eurorack and I'd love to get some feedback and module recommendations for my rack.

My main goal is to make techno, but I also want to be able to patch polyphonic sounds occasionally.

I've attached a picture of my planned rack. Out of the modules shown in the picture, I have already purchased the Cwejman QMMF-4, Livewire AFG, and R-56.

Could you give me some advice on what modules I might be missing, or suggest any changes to my current plan? Any feedback or recommendations for a beginner would be greatly appreciated!

Thanks in advance!

The modules you have purchased are really really good. I'm jealous.

And I see that you have a large budget.
But more money doesn't automaticaly mean more quality.

For live techno you need. (I don't know if you want to do live techno. Or that you have extra equipment.)
1 - A kick. That's not in your case.
2 - Hihats. That's not in your case.
3 - Some toms. That's not in your case.
4 - 2 complete synth voices, or more.
5 - A delay, a reverb (R56 is very cool) and some modulation.
6 - A sequencer. I don't know the ER-101-102, but it has only 4 tracks.
7 - A mixer. Better is to have 2 so you can do sidechaining.

But you can make all these things with the chosen modules. Just not all at the same time.

Some tips:
A spring reverb is great, but with some extra it can be awsome.
I have a Benidub spring reverb that has a filter added with modulation. I use the S&H modulation on that all the time.
And I send it through a BBD echo and compressor. Now the reverb becomes like an extra voice that is alway's there in the background.
So spring reverb into filter with modulation, into BBD (or other echo), into compressor, into mixer.
Cheap BBD's and compressors are imo better in this case than expencive ones.

Modulation like, chorus, phasing and flanging is handy , so your sounds are never static.

Echo, I use 2 of them in series. The first is a bit longer than the second and it has very little bass and trebble.
So the first one can be a BBD echo with the low's cut into a digital echo. A quarter note into a dotted 8th is very nice.

Kicks. Try sending it to a highpass filter in combination with a crossfader.
So kick into crossfader (for the normal kick sound) into mixer.
And then a parallel signal path. Kick into highpass filter into crossfader.
By combining the 2 signal paths with the crossfader and various filter settings, you can get some very interesting kick sounds.
Great for transitions to.

The Bohm system is mentioned and seems atm the most popular kick module.
With the complete system, you can do amazing rumbles, sidechaining, and transition efx.
It is a lot of money, but not expencive.

A synth voice consists of a oscillator, a filter, a vca and an envelope.
This is the minumum. But there are lots of single modules that contain all of this.

Last tip: Go slow on your purchases.

Hi, I'm not sure what a 303 specific slew limiter would be like, but for slew limitation I use and like the Schlappi Engineering Boundary. Maths can also do it.

On the Boundary you would go v/oct into SLEW and then send a trigger to RISE on notes you want to slide to lengthen the attack phase.

Hoi Stef,

When going from one note to the next, a 303 type slew limiter uses the same time no matter how far apart the notes are.

It seems to me that the Boundary and Masths can't do that. They are normal slew limiters.

WMD makes the Time Warp. Should get you pretty close.

Hello Farkas,

Yes, this can do it.
And there are 2 of them.

Are the more?

hello people,

I've been on modular grid for many many years, but this is my first forum post.

I'm looking for a 303 type slew limiter for my acid beast case.
I know of the ADDAC 209, but are there any other?

Best R2D2.
