What's a good alternative to moogladder filter?

Subject	What's a good alternative to moogladder filter?
	I like the moogladder filter a lot. But unfortunately it uses a lot of CPU. It's super cool filter but it's not the thing you are going to use on weaker PCs or mobiles. It's easy to hit the top of performance with several of them. Is there a good filter that is close to moogladder but not so heavy on resources? Another question on filters: What filter is close to Massive NI low pass 2 or low pass 4 filter in Csound?

	There is a notion that the most important thing in the synthesizer is a filter. The quality of the filter determines the specific voice of your synth. Csound has wide range of filters it's easy to get lost in them. So what is your experience with filters? Which are good for pads and which are good for leads. If you have any experience with that and interested in sharing it I think that this information can be useful for many csound users. 2016-03-16 16:34 GMT+03:00 Anton Kholomiov <anton.kholomiov@gmail.com>: I like the moogladder filter a lot.

	You're right, that would be useful! I was considering asking a similar question recently, it is a very good question. I know they've recently introduced the mvc filters, which have a nice analogue-like characteristic. But I have wondered often if people have any preference over the unashamedly digital filters, because as you say, there are so many. I find myself often defaulting to bqrez for anything other than lowpass filters, because it's the only multi-mode filter that doesn't output multiple audio streams, and it makes my instrument less messy, but that's a terrible reason to use a filter! I should really spend more time comparing different filters in different situations and get to know them better.

	I've got some problems when I stuck two moogladers in chain to increase the order of the filter and if use several of them for each voice for the stereo signal and if I have several voices. Then I can get buffer underruns. But when I switch to bqrez there are no problems with performance. The CPU load drops dramatically and so drops the quality of the sound :) So I try to investigate.

Subject	Re: What's a good alternative to moogladder filter?
	@ Victor I've got performance scores for various filters. I've implemented a pad-instrument with sequence of two filters of the same type. The results shows CPU usage in percent for 8 notes chord (it uses 16 instances of the given filter): ~~~ moogladder -- 60 % lpf18 -- 33 bqrez -- 27 moogvcf -- 26 clfilt -- 19 lowres -- 17 ; new mvc filters mvclpf1 -- 30 mvclpf2 -- 32 mvclpf3 -- 45 mvclpf4 -- segfaults ~~~ Maybe I can open issue for optimization of moogladder. The sound quality is very good but if the tanh would be replaced with table Maybe I would post a look up it can also speed up performance. I think I can post a sound examples later. To my ears moogladder, moogvcf, mvclpfNs produce soft mellow sounds clfilt, lowres are more harsh but it reminds me some examples of oldschool dance timbres I like lowres a lot it has it's own interesting character.

Subject	Re: What's a good alternative to moogladder filter?
	Another example of using Csound filters. This time in dubstep context and with some other filters. Includes: moogladder, moogvcf, lpf18, bqrez, lowres, mvclpf1, mvclpf2, mvclpf3, clfilt, butterlp, rezzy, svfilter, vlowres, statevar. https://www.dropbox.com/s/0hamb1811hv1gjk/dub-filters.zip?dl=0 The original example for moogladder was coded by Jacob Joaquin Anton 2016-03-17 23:39 GMT+03:00 Anton Kholomiov <anton.kholomiov@gmail.com>: Audio examples of using Csound filters to implement a PAD-timbre: https://www.dropbox.com/s/mhfpudm46236ozl/csound-filters-pads.zip?dl=0 there are dry and processed with reverb audio files. So that you can listen to the difference between various csound filters 2016-03-17 22:41 GMT+03:00 Victor Lazzarini <Victor.Lazzarini@nuim.ie>: moogvcf4 segfaults? Please open an issue for us to investigate.

I've implemented a pad-instrument with sequence of two filters of the same type. The results shows CPU usage in percent for 8 notes chord (it uses 16 instances of the given filter): ~~~ moogladder -- 60 % lpf18 -- 33 bqrez -- 27 moogvcf -- 26 clfilt -- 19 lowres -- 17 ; new mvc filters mvclpf1 -- 30 mvclpf2 -- 32 mvclpf3 -- 45 mvclpf4 -- segfaults ~~~ Maybe I can open issue for optimization of moogladder. The sound quality is very good but if the tanh would be replaced with table Maybe I would post a look up it can also speed up performance. I think I can post a sound examples later. To my ears moogladder, moogvcf, mvclpfNs produce soft mellow sounds clfilt, lowres are more harsh but it reminds me some examples of oldschool dance timbres I like lowres a lot it has it's own interesting character.

Subject	Re: What's a good alternative to moogladder filter?
	Cheers very much Anton! These are some great comparisons. I've really enjoyed and got great results from tbvcf, but it is quite glitchy (only in the way it states in the manual mind), and the results depend entirely on the sr. What's peoples general opinion on tbvcf? Is it a lost cause? Should I stop using it? I foolishly thought one day that I could fix the sr issue, and delved into the code, but quickly realised I was in way over my head, lol On Fri, Mar 18, 2016 at 9:02 AM, Anton Kholomiov wrote: > Another example of using Csound filters.

Subject	Re: What's a good alternative to moogladder filter?
	I thought we may use the new Csound site actually. We need to start building up content on it. A clean embedded player would be nice.

I've implemented a pad-instrument with sequence of two filters of the same type. The results shows CPU usage in percent for 8 notes chord (it uses 16 instances of the given filter): ~~~ moogladder -- 60 % lpf18 -- 33 bqrez -- 27 moogvcf -- 26 clfilt -- 19 lowres -- 17 ; new mvc filters mvclpf1 -- 30 mvclpf2 -- 32 mvclpf3 -- 45 mvclpf4 -- segfaults ~~~ Maybe I can open issue for optimization of moogladder. The sound quality is very good but if the tanh would be replaced with table Maybe I would post a look up it can also speed up performance. I think I can post a sound examples later. To my ears moogladder, moogvcf, mvclpfNs produce soft mellow sounds clfilt, lowres are more harsh but it reminds me some examples of oldschool dance timbres I like lowres a lot it has it's own interesting character.

From	"Dr. Richard Boulanger"
Subject	Re: What's a good alternative to moogladder filter?
	Great plan. I am trying to push everything from csounds.com over to the new site - which I love. I "finally" have all the videos from the Csound Conference at Berklee (at long last) and plan to post these so that Csounders can enjoy and learn from them. And many other things. All happening over the next months. -dB On Sun, Mar 20, 2016 at 11:26 AM, Rory Walsh <rorywalsh@ear.ie> wrote: I thought we may use the new Csound site actually.

The sound quality is very good but if the tanh would be replaced with table Maybe I would post a look up it can also speed up performance. I think I can post a sound examples later. To my ears moogladder, moogvcf, mvclpfNs produce soft mellow sounds clfilt, lowres are more harsh but it reminds me some examples of oldschool dance timbres I like lowres a lot it has it's own interesting character.

Attachments	csound-filters.zip
	@Joachim I've encoded it in Csound. You can find the comparison of Csound filters on three expamples: * dubstep bass sound * pad sound * polysynth sound Hopefully it can be useful for someone interested in csound filters. maybe for FLOSS manual too. Feel free to change everything. The files can be rendered in two ways: ; plays back live i "PlayAll" 0 0 0.35 ; records everything to wav files (one per filter) i "DumpAll" 0 0 0.35 2016-03-22 0:56 GMT+03:00 joachim heintz <jh@joachimheintz.de>: great. it's allright if you send me a preliminary version; i can then adapt it to fit into the floss manual. joachim On 21/03/16 20:39, Anton Kholomiov wrote: Then I need to translate my code to readable csound code.

I've implemented a pad-instrument with sequence of two filters of the same type. The results shows CPU usage in percent for 8 notes chord (it uses 16 instances of the given filter): ~~~ moogladder -- 60 % lpf18 -- 33 bqrez -- 27 moogvcf -- 26 clfilt -- 19 lowres -- 17 ; new mvc filters mvclpf1 -- 30 mvclpf2 -- 32 mvclpf3 -- 45 mvclpf4 -- segfaults ~~~ Maybe I can open issue for optimization of moogladder. The sound quality is very good but if the tanh would be replaced with table Maybe I would post a look up it can also speed up performance. I think I can post a sound examples later. To my ears moogladder, moogvcf, mvclpfNs produce soft mellow sounds clfilt, lowres are more harsh but it reminds me some examples of oldschool dance timbres I like lowres a lot it has it's own interesting character.

Attachments	Hives.csd
	Nice one Anton! That's pretty damn useful. I'm also working on something in Cabbage that might be of use here. I'm (hopefully) making a super flexible vst that'll help me develop instruments for my app quicker. I only started using Cabbage today, so it's early days, but so far I have a sawtooth wave going through a selectable filter, and a reverb unit (the selectable filter being the focus of my work so far). If anyone does try it out, it's mostly just lowpass filters implemented so far, and any that aren't implemented don't have controls, so you'll spot them.

Subject	Re: What's a good alternative to moogladder filter?
	Ha, I'm almost done implementing the dub-step filter examples as a Cabbage instrument. I'm just curious as to what iCoeff and giSpb control? I'd like to add some controls for them, but would like to know more about them first! On 31 March 2016 at 17:38, Peter Burgess <pete.soundtechnician@gmail.com> wrote: Nice one Anton! That's pretty damn useful. I'm also working on something in Cabbage that might be of use here. I'm (hopefully) making a super flexible vst that'll help me develop instruments for my app quicker. I only started using Cabbage today, so it's early days, but so far I have a sawtooth wave going through a selectable filter, and a reverb unit (the selectable filter being the focus of my work so far). If anyone does try it out, it's mostly just lowpass filters implemented so far, and any that aren't implemented don't have controls, so you'll spot them.

Subject	Re: What's a good alternative to moogladder filter?
	Ok, I figure it out ;) On 31 March 2016 at 17:45, Rory Walsh <rorywalsh@ear.ie> wrote: Ha, I'm almost done implementing the dub-step filter examples as a Cabbage instrument. I'm just curious as to what iCoeff and giSpb control? I'd like to add some controls for them, but would like to know more about them first! On 31 March 2016 at 17:38, Peter Burgess <pete.soundtechnician@gmail.com> wrote: Nice one Anton! That's pretty damn useful. I'm also working on something in Cabbage that might be of use here. I'm (hopefully) making a super flexible vst that'll help me develop instruments for my app quicker. I only started using Cabbage today, so it's early days, but so far I have a sawtooth wave going through a selectable filter, and a reverb unit (the selectable filter being the focus of my work so far). If anyone does try it out, it's mostly just lowpass filters implemented so far, and any that aren't implemented don't have controls, so you'll spot them.

	Here's my simple Cabbage VST. it's very nice to be able to quicly hear the difference between all these filters. Thanks again Anton!

I'm (hopefully) making a super flexible vst that'll help me develop instruments for my app quicker. I only started using Cabbage today, so it's early days, but so far I have a sawtooth wave going through a selectable filter, and a reverb unit (the selectable filter being the focus of my work so far). If anyone does try it out, it's mostly just lowpass filters implemented so far, and any that aren't implemented don't have controls, so you'll spot them.

Subject	Re: What's a good alternative to moogladder filter?
	I'm glad that you find it useful! I like how statevar sounds with pad. it produces really soft and gentle sound. Anton 2016-03-31 19:59 GMT+03:00 Rory Walsh <rorywalsh@ear.ie>: Here's my simple Cabbage VST. it's very nice to be able to quicly hear the difference between all these filters. Thanks again Anton!

On 31 March 2016 at 17:38, Peter Burgess <pete.soundtechnician@gmail.com> wrote: Nice one Anton! That's pretty damn useful. I'm also working on something in Cabbage that might be of use here. I'm (hopefully) making a super flexible vst that'll help me develop instruments for my app quicker. I only started using Cabbage today, so it's early days, but so far I have a sawtooth wave going through a selectable filter, and a reverb unit (the selectable filter being the focus of my work so far). If anyone does try it out, it's mostly just lowpass filters implemented so far, and any that aren't implemented don't have controls, so you'll spot them.

I'm (hopefully) making a super flexible vst that'll help me develop instruments for my app quicker. I only started using Cabbage today, so it's early days, but so far I have a sawtooth wave going through a selectable filter, and a reverb unit (the selectable filter being the focus of my work so far). If anyone does try it out, it's mostly just lowpass filters implemented so far, and any that aren't implemented don't have controls, so you'll spot them.

Subject	Re: What's a good alternative to moogladder filter?
	Ok, I've developed my cabbage instrument a little further.... as well as slightly extending the features, it now has a button that prints out a csound instrument with only the selected opcodes and current parameters :D I don't know if this will be of any use to anyone else, but it's gonna massively speed up my own development! When I've tidied it up a little, anyone want a gander?

Subject	Re: What's a good alternative to moogladder filter?
	It would be cool to have a non-MVC one. I opened them all up in Qt and Cabbage and they look like they will be a ton of fun to use and very helpful in our sonic explorations. -dB On Fri, Apr 1, 2016 at 1:43 PM, Peter Burgess <pete.soundtechnician@gmail.com> wrote: Ah, is that because of the new mvc filters?

Subject	Re: What's a good alternative to moogladder filter?
	Sure I do! I'm sure everyone on the cabbage forum would too. We have a special cabbage 'recipes' thread for sharing instruments ;) On 1 Apr 2016 5:26 pm, "Peter Burgess" <pete.soundtechnician@gmail.com> wrote: Ok, I've developed my cabbage instrument a little further.... as well as slightly extending the features, it now has a button that prints out a csound instrument with only the selected opcodes and current parameters :D I don't know if this will be of any use to anyone else, but it's gonna massively speed up my own development! When I've tidied it up a little, anyone want a gander?

Subject	Re: What's a good alternative to moogladder filter?
Attachments	ARDevSynth.zip
	Ok, here's the first prototype of my VST. It's far from fully functional, some of the knobs don't work, the envelopes aren't implemented quite right, and not all the filters are active (if the cutoff knob disappears, that means it aint gonna work!). Any pointers or ideas welcome! One problem with it is that there isn't any sound until you change the attack slider on whichever envelope is affecting the oscillator amp. I guess that's either to do with my implementation or to do with cabbage, I better ask in cabbage forum. The main feature is the "snap" button, which takes a snapshot of the current patch, taking into account all knob values, and prints out a Csound friendly instrument including ONLY what's needed. That's only working on the filters and oscillator at the moment too, and doesn't print out most values, lol, but you can see the idea I'm working on anyway. If anyone’s interested in seeing that bit, it's all in ARDevSynth_Snapshot.udo, and referenced in the main .csd from lines 463-475. If anyone would be interested in a simpler example of the csound snapshot bit, I'd be happy to knock one up. @Rory: is cabbage recipes section of the forum for finished goods or any kind of examples?

From	Rory Walsh
Subject	Re: What's a good alternative to moogladder filter?
	The reason you need to change the attack sliders before you get any sound is that you have them initialised to 0. If you are building yourself on Linux you can rebuild from the current dev branch. There, if the initial value is lower than min, it will be be replaced with min. Otherwise you'll need to update your source. Btw, with the latest version of Csound this instrument causes INIT errors because of changes made to envelopes. I hope it gets fixed because it has broken quite a lot of instruments. Apart from that this is a very interesting idea. A Csound instrument that creates Csound instrument. Very meta ;) Btw, you can easily have a 'save' dialogue appear if you wish to name, and save those snapshots to a special location. Although in your case I guess you want work as quickly as you can, so you're probably better off doing it brute force. There is also a preset system in Cabbage whereby you can save any of your instruments settings so they can be recalled later. They are saved as xml data in a file that looks something like this: <?xml version="1.0" encoding="UTF-8"?> <MySImpleInstrument att="0.25400000810623168945" dec="0.40000000596046447754" sus="0.70000004768371582031" rel="0.80000001192092895508" combochan="1"/> Each xml name is a Csound channel. Perhaps it might also be useful for you. You could then simply read the xml data and use it to set your Csound channels. You could also transition between presets quite smoothly. Anyhow, please do share it on the Cabbage forum. It's a pretty neat idea.

Subject	Re: What's a good alternative to moogladder filter?
	Btw, your synth keeps causing dropouts here, but I'm not really sure why. You're not having any issues with the audio on your side I take it? What OS are you using? On 4 April 2016 at 23:10, Rory Walsh <rorywalsh@ear.ie> wrote: The reason you need to change the attack sliders before you get any sound is that you have them initialised to 0. If you are building yourself on Linux you can rebuild from the current dev branch. There, if the initial value is lower than min, it will be be replaced with min. Otherwise you'll need to update your source. Btw, with the latest version of Csound this instrument causes INIT errors because of changes made to envelopes. I hope it gets fixed because it has broken quite a lot of instruments. Apart from that this is a very interesting idea. A Csound instrument that creates Csound instrument. Very meta ;) Btw, you can easily have a 'save' dialogue appear if you wish to name, and save those snapshots to a special location. Although in your case I guess you want work as quickly as you can, so you're probably better off doing it brute force. There is also a preset system in Cabbage whereby you can save any of your instruments settings so they can be recalled later. They are saved as xml data in a file that looks something like this: <?xml version="1.0" encoding="UTF-8"?> <MySImpleInstrument att="0.25400000810623168945" dec="0.40000000596046447754" sus="0.70000004768371582031" rel="0.80000001192092895508" combochan="1"/> Each xml name is a Csound channel. Perhaps it might also be useful for you. You could then simply read the xml data and use it to set your Csound channels. You could also transition between presets quite smoothly. Anyhow, please do share it on the Cabbage forum. It's a pretty neat idea.

Subject	Re: What's a good alternative to moogladder filter?
	Cheers for all the tips! I was wondering whether I could add a save path, I've already got the filename set as a string, so it shouldn’t be too much work to add a GUI option for that. I'm also totally onboard adding presets, I've started collecting some simple template instruments in .csd's for various types of signal generators and what not, it would be much easier if they were all just presets in my vst! I hadn't noticed that I'd kept the envelope attack default at 0. I changed the min to 0.0001 to see if it helped, and forgot to change the default! I've changed that now, and it's working straight off the bat! I've not had any trouble with audio dropouts. I'm on Ubuntu 14.04, and I think I last built Csound straight after the mvc filters were added. I'm also running all audio through jack now, not sure if that'll make any odds though. I did have some other problems with the envelopes though, that I've just seen have also been cleared up by changing the default attack setting to 0.0001. It wasn't happening with expsegr or transegr, only linsegr, but I'm not sure if that would cause the dropouts. I'll send a version with the fixed envelopes shortly Csound mailing list Csound@listserv.heanet.ie https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND Send bugs reports to https://github.com/csound/csound/issues Discussions of bugs and features can be posted here

	You can find an example of how to save presets in the Preset.csd file from the 'Instructional' example folder. I get no dropout on my Mac, so it must be just be my Linux box.
