Request a new device/modular module, and hope that some enterprising developer grants your wish!

Oberheim Filter

Post by al_bot »

Was there an Oberheim like filter anywhere in scope, instrument or in modular?
I use the SATURN device and like it (except for the old style saving), but was hoping there was another.

Thanks!

Which "Oberheim like" filter do you mean ?
There existed different vintage Oberheim synths and there are today´s Tom Oberheim products cloning the vintage hardaware as also DSI/Tom Oberheim OB-6.

vintage:
The SEM , SVF and OB-X 2-pole low-, band-, hi-pass and notch filter w/ resonance
12dB LPF of OBX-a (2x CEM 3320 per voice)
12dB/24dB CEM- of OB-8 (1x CEM 3320 per voice)
The multimode filter generated by CEM 3372 signal generator of Xpander and Matrix-12
24dB LPF inside CEM 3396 (synth- on- a- chip) of Matrix-6 /Matrix-1000

They all sound different.

Good point, I should have clarified. Something like the Matrix-6 or the OB-Xa. :)

since you mention saturn, you mean the possibility of crossfading.
orbiton syn-chrome offers similar. I like that very much.

a transition is feasible. correct morphing less. but if the result is right.
look here

and

morphing could be possible with a filter bank mutation :wink:

Matrix-6 is the easiest to model.
It´s just only a 24dB LPF.
OB-Xa used 2 CEM chips,- possibly 1 for the 2-pole (12dB) and the other for the 4-pole (24dB) filter.

But I myself,- I´d prefer the classic SEM state variable filter.

In fact, I´d like to have a SEM model for SCOPE and a shell mimiking key assignment options, offering global PB, vibrato and VCF cutoff controls, so a user is able stacking SEMs inside that shell.
In addition we´d get access to originally "internal" patchpoints and were able using these w/ SCOPE Modular.

Well, I can dream ... :lol:

B.t.w.,- the old Creamware "Blue Synth" device got new love on my end.
IMO it works very well for a lot of polyphonic synth patches while saving a lot of DSP cycles.

How is crossfading betweem LP, BP and HP realised in Syn-Chrome ?

You just remind me on getting keys for the Orbitone devices,-

thank you !

Hello Spielraum, cool device, thx!

Also, quick question, the bcmodular - CEM3320 LP filter, I didn't see it in the Version 0.98b install or any of the older zips. Didn't see it in github list either.

Where do I download this filter module? Thx!
