Roland 521 VCF - Dual Analog Filter Overview

[@YoYoYo]

This is a really nice sounding filter! I quite like it.

[@samirabiamodular6212]

Agreed, It's a great filter

[@SquarepusherCentral]

Oh man, that stereo patch!

[@RobertSaintJohn]

Another great video, thanks again. And great patches starting at 7:04!

[@samirabiamodular6212]

[@station2station544]

That filter is genuine Roland sound. And I desperately need an E-330

[@theinternetseekers2436]

Sounds fucking amazing

[@robertsyrett1992]

really nice sounds!

[@samirabiamodular6212]

Thank you!

Had a chance to play with this dual filter recently. It sounds great, but I am partial to Roland filter sounds. I agree the build quality is nice. The only thing is the placement of the cutoff and rez knobs. I just feel like it could have been laid out a little better as sometimes things feel a bit clumsy. Thoughts?

[@SolarDeathRay]

I have one and I must agree with what you're saying about how it's laid out. I'm definitely keeping it though. It just sounds so great. As a fan of Roland filter designs, I'm thinking about adding a Jove to my rack. My only gripe with that one being the lack of key-tracking. Can't have it all I guess. :)

[@sunilsolanki]

Excellent video. Thanks so much! How did you get the sound and sequence at 5:05? Very acid psy vibes. Sounded so good!

[@AiynZahevSounds]

sunil solanki thanks! The Metropolis was sending CV to the cutoff. I'm not sure how else to describe it but let me know if you have specific questions

[@lebannerfan65]

@@AiynZahevSounds any idea what you did for the 'bubbly' bassline going into the VCF? So it's that bubbly bassline + sequencing the cutoff w Metropolis? Loooove that sound. Does that sound right?

[@AiynZahevSounds]

@@lebannerfan65 Yeah it's just the same bass note, a sawtooth, and the filter is being sequenced by CV from the sequencer

[@lebannerfan65]

@@AiynZahevSounds that is one super musical cut off and resonance section then! :)) Just bought one because of your video. Should here after the weekend!

[@AiynZahevSounds]

@@lebannerfan65 Yes I love this filter. Roland filters are awesome.

[@user-ed5ix1sw6i]

for the stereo patch, couldn't you have achieved the same with just one mono signal and duplicated it to both channels...?

[@samirabiamodular6212]

A signal is stereo when there is a difference between left and right channels. That's why I'm using a different OSC to feed each filter. If you just duplicate the same sound to Left and Right you still end up with a mono signal.

[@user-ed5ix1sw6i]

Thanks for the reply. I still don't quite understand; isn't each oscillator identical (same pulse wave and frequency)...? Or are they being modulated differently slightly?

[@samirabiamodular6212]

The nature of the oscillators creates the differences. The phase on each channel will be different and the tuning will almost always be slightly different. These add up to create a stereo image.

[@user-ed5ix1sw6i]

Ah, I see, thanks for explaining! Guess i'll have to get both of these modules now ;-)

[@deadmoldable]

do the inputs only attenuate or do they some db uplift also?

[@samirabiamodular6212]

They just attenuate

[@deadmoldable]

thx for the info. i was hoping it does a little bit amping.
