LP / HP Filters

Someone asked me what is LP2 and LP4, etc, the numbers behind the low pass, what do they mean. I figured someone else might wanna know too.

Low Pass Filters

very nice explanation!

here is a easy to build MS-20 style low-pass-filter for all the people whose machines only have non self resonating filters: https://www.lookmumnocomputer.com/projects/#/simple-filter

Damn they really stepped up the manual since I last looked. Never seen the Mpc 3000 LP...
There was nothing like that 3 years ago...
weird to se you FTFM lamp and post about it. I got the live bible and worked through it and never looked back.

Great post LAMP.
Key Advice backed by resources/images.

I default to the MPC 3000 filter b/c it simple & sounds pretty good on most stuff I run thru it. I’ve been meaning to try the VOCAL filters on some vocal chops I did last year on my roland MV.

I actually get overwhelmed by the MPC filter options so I find myself reverting to analog filters. If you have never had any analog gear, I suggest u get at least 1 for filter purposes. A true analog oscillator/filter is powerful & simple like a pump action shotgun. Glocs & GALILs are nice but nothing is quite like a Mossberg 500. I know there are horde of fine plugins/VSTs, but nothing is quite like a real analog filter sweep/LFO. The joy of turning 2-3 knobs & getting amazing results. I tend to save digital FX for things analog could never do like initial audio or KORG KAOSS.

I have never owned any expensive/vintage synths [dave smith/moog] or modular [???} but I rec the current novation BS 2 for the price. There is a lot of magic in finding a cheap piece of analog gear & getting “out of the box” textures. When u find what works for you, you will have a sound that only you know how to spin. My only suggestion is that u build your sound around a piece of equipment that can be easily replaced NOT some obscure or expensive unit. There is a big difference between gear collector & musician. I only keep 2 analog synths around.

Keep in mind that the signal will be MONO now & that you should have the sequencer running to keep the filter open. The elektron heat is pricy but compact & stereo. See the sweetwater post below.

Hello!

Sometimes i use the external input on my alesis micron to send some audio thru its filters. There are like 20 different types of filters in several "flavours" like moog-type or oberheim-type of which some sound amazing, but it is not much fun as the realtime control is lacking.

My E-MU Morpheus synth has 192 different filter types and a technology called z-plane filter, which is a combination of a low-pass filter and six bands of eq, all freely configurable, so that filter has 14 poles. The real trick of that filter is its ability to sweep those settings in a three-dimensional fashion, a little bit like the morphing of sounds in vector synthesis on a korg wavestation. This synth unfortunately has no audio input so the filter can only be used internal. If somebody wants a filter like that standalone, then there is the morpheus filter module for eurorack by rossum electro-music from one of the founders of E-MU.

That little MS-20 filter i build from the lookmumnocomputer website is getting used much more recently even if it still sits in a cardboard box like in the prototype stage because i could not make a real case just yet. This simple resonating low pass filter in combination with a real simple lfo for cv is so much hands on fun with instant gratification in sound. If somebody can not build this for whatever reason then i recommend to buy a cheap korg monotron which has the same MS-20 filter and an aux-input!

I'd dig that. I check these forms most days even though I don't participate much (I'm a noob and don't have a lot to contribute yet). There's a lot of knowledge and opinions here and I appreciate that. I learn something new from y'all just about every day.
