TubeOhm SMR4P-Multi

video upload by Andre' Laska

"Stress test of the filter. No audio in signal was used. All sounds were generated with the filter resonance. A signal generator was only used to control the resonance and the different filter types. The video is handheld with a mobile phone. I thought it would be interesting for you to see what the filter alone can do.
The sound was recorded with a mobile phone."

The SMR4P-Multi contains the best from 2 worlds . First , it sounds warm like the SMR4 and second -
15 different filtertypes like the 4PM.
While doing sounddesign it is very helpfull to have a ' swiss knive' VCF. So we implement 15 different filtertypes like
6+12+18+24dB LP 6+12+18 dB HP 6+12 dB BP HP2LP, HP3LP Notch,Phaser, Notch+LP1, Phaser+LP1.

What else we have build in ?
There is also a FM posibility, an inbuild VCA , and you can switch the different filtertypes a:) manual or b:) voltage controlled.
Inputs: Audio in, Res= resonance contol (0..10 V),Gain(VCA control 0..10V) , Mod (extern) and Cut(V/OCT0..10V)
Outputs : VCA and VCF *** VCA, the output singal is contolled in its amplitude by Gain 0..10 v
VCF is the direct signal without VCA controll
DIY scills : good soldering knowledge , high integrated parts - through hole , no SMT
