Custom Controls Tutorial

Great'un! Thanks oddson!

Anyone having troubles with doing their own GUI stuff could probably learn a bit from this tutorial, so go check it out!

oddson · 28 Aug 2006

Thanks Stefen... it's a work in progress.

I'm learning something too because I'm moving toward fully custom controls and I needed to understand how to add the preset, midi CC, MinMax etc. to my controls.

BTW - the toolbox should have these mid/low level modules with proper tool-tips.

sambean · 29 Aug 2006

Added a couple of common questions to the FAQ, feel free to expand/edit..

Sam

oh, and oddson, again, muchos muchos cudos for the effort you've put into the wiki !i!i

AM GUI Stuff 😉

stefan · 8 Sept 2006

Hm. Due to a security breach I had to remove the bin folder in the wiki. I'm not sure if this actually affects anything (at a first glance the wiki seems just fine 🙂), but if it does, keep in mind that it's just temporary.

Good thing I'm on the mailing list atleast 🙂

group project: XYpad [old link]

Optimization [old link] Including a way to reduce the ASM code needed for the typical min(max(input,-1),1); by half! Makes me think that using primitives for stream maths is very wasteful... GUI'd version comming soon.

infuzion · 17 Jan 2007

I've done a ton of adding & editing over the past month, best to check it here: [old link] & thanks for everyone's (past & future) work on the WIKI! 😇

angstrom · 6 Feb 2007

I've added my old SE 'how to make buttons in Photoshop' tutorial to the SM wiki. It makes some mention of a prior section which I have not yet converted, ignore that - it's just me waffling about graphical conventions and planning your interface. I'll put it up some other day.

[old link]

exonerate · 6 Feb 2007

i've added a tutorial that show's a filter coded in c++ and the resulting synthmaker code , there's also a download link for the filter. C++ filter ported to sm code component

Kara · 6 Feb 2007

Excelent !

Thanks a lot for publishing this.

I could use a couple more of those 🙂

exonerate · 4 Mar 2007

Added a little modification to the standard wave draw module, i've put it in the instruments section............well it needs something in there 😉 [old link]

infuzion · 5 Mar 2007

Thanks for adding that to the WiKi! Neat stuff... How would you approach letting users morph both standard & user-defined waves?

BTW, I hope you didn't mind the little tweaking I did to your tutorial; I just wanted to make it more clear & easier to jump around.

exonerate · 5 Mar 2007

How would you approach letting users morph both standard & user-defined waves?

Thats a good question!, i was thinking about that today at work, and what i'm probally going to do is make it so you have a drop down list of about 50 waves including the standard ones, that you can load in to the slots as well as load your own, i'm not sure whats going to be the best way to implement it, but it would be cool if i could make a drop down list like the windows ones where you can hover over the slot and then move the mouse across to give you the list of waves, i'm not sure if this would be possible though, i would probally have to create my own drop down list from scratch, not something i want to do. i will implement it in some way though 😉

BTW, I hope you didn't mind the little tweaking I did to your tutorial; I just wanted to make it more clear & easier to jump around.

thats fine 😉 you did me a favour, that was my first time adding any thing to the wiki, you made it just how i wanted it to look.

cheers 😉

infuzion · 25 Apr 2007

Lots of updates, little new from me: [old link] Thanks to unkargherth, BasherT, & exonerate for their recent hard work on the WiKi!

Note to newbies: Please, when you ask for help, add your question & answer to the WiKi! There are a few pages for FAQ, examples, etc... often you can just update an existing page with clearer information (keep w/in the style for that page). Don't worry about messing things up; it is alot easier for someone like me to edit/move text that someone else typed in (to make it more clear or keep with the established style) than to type it in all myself.

I won't say you must add to the WiKi if you get help here on the forum, but if you expect someone to help you, please pass on the efforts to the future. 😇

infuzion · 25 Apr 2007

URL style tip: You don't have to repeat the page title, in fact it is much better you don't to keep the URL shorter. For example, by default for some reason the WiKi would have titled my page like this: [old link] Instead I chopped off the end part after the : making the URL shorter & works the same: [old link]

cheers! 😇

exonerate · 27 Apr 2007

Added sample player/looper and updated wave draw mod.. [old link]

oddson · 8 May 2007

I'm adding a 'Beginners' tutorial. [old link]

It will be a series of lessons from "what the heck do I do first?" up to "time to turn 'Developers' mode on."

Here are some thoughts for early topics. Any comments are welcome.

Part 1 - Making a Sound Part 2 - Adding ADSR Part 3 - Adding a Filter Part 4 - Adding Effects Part 5 - Adding Velocity to volume modulation Part 6 - Modulating Pitch Part 7 - Modulating Pan etc....

stefan · 8 May 2007

Awesome!

oddson wrote: I'm adding a 'Beginners' tutorial.

cool man it is needed! Suggestions: Please dd in the very basic basic things, like multiplications (like how the Amp works), adding (by connecting links together on the same connector), & audio & programming terms (I thought Pan meant L/R movement). cheers

oddson · 8 May 2007

'dd' as a verb... hmm.

I'm thinking of adding a glossary in addition to the 'concepts' page. But on the first pass through I'm just going for the text.

infuzion · 9 May 2007

changes needed This is mostly for my own reference, but if someone else wants to update a page or 3 themselves, go for it! Just ensure you're in the same format, & your spelling is good (firefox 2.0 works well here). adsr Wave Draw OSC Alot of components are missing definitions.

oddson · 9 May 2007

A lot of components are missing definitions.

I made virtually all the component reference entries (that's what earned my 'WIKI Guru" designation) but I stopped once Malc published the PDF Component Reference.

I'd like to update the WIKI and include many more example OSMs.

They are very effective in showing how something really works.

But... it's a huge task and realistically it's not happening any time soon.

Right now what time I can spare is going to my Beginners tutorials.

(There's also a fair bit of info in there that's now inaccurate.) 🙁

-PS- @ exonerate - can you put that seriously-long URL inside a URL tag? This page is way too wide.

stefan · 9 May 2007

Wow, a lot of good stuff going on at the Wiki now!

BTW, I saw (in the Linking knobs and sliders tutorial) that some images are too wide to fit within the content, you can automatically resize the images by specifying a width, like this:

{{wiki:dokuwiki-128.png?50}} where 50 is the max width of the picture. Around 670 or so should be good for wiki articles. Just a friendly tip 🙂

exonerate · 9 May 2007

yeah stefan i put that in last night and then realised that they were over hanging, i though there was a way to do it on the wiki, was going to ask about that today.

cheers 😉

exonerate · 9 May 2007

i've added a tutorial which shows you how to link knobs or sliders.... [old link]

jobro · 11 May 2007

Oscilators section added.

Adding some oscilators to that, will give links here when done.

TB303 oscilator Juno 106 oscilator

rl · 11 May 2007

Hmm,... I think the Term "TB-303 oscillator" is a bit misleading. Your schematic uses the standard SM oscillators offering mathematically exact saw and pulse waveforms with bandlimiting applied, but that's not what justifies it to be a TB-303-like oscillator. I can't find the info right now, but the waveforms of the real machin looks rather different.

jobro · 11 May 2007

Well I tried to develope an oscilator that comes close to the original 303 with the existing oscilators I have at hand.

infuzion · 12 May 2007

jobro wrote: Well I tried to develope an oscilator that comes close to the original 303 with the existing oscilators I have at hand.

Don't feel bad; the tb303 hosted here at SM's website used the same OSCs. MyCo did a better simulation using wavetables IMHO, but they kinda do inherit the low-octave issues discussed in the Ideas thread.

Oddson: nice work w/the tutorials! Even I learned something 😇

jobro · 12 May 2007

Feeling bad you say? Nah it's ok I take this only as constructive criticism.

infuzion · 12 May 2007

Well, it is a good example on how to make an OSC switch... maybe it should be promoted as a GUI, & it happens to be a "working example".

nippybaynes404 · 12 May 2007

I have some of the juno shapes sampled on my computer and I will try to dig them out later. 😉

jobro · 13 May 2007

I made a nicer switch for my own synths, will update the example with it.

cheers

oddson · 19 May 2007

It doesn't much matter now as its a page back... but you can put URLs inside a tag like this [url=http://domain.ca/page.htm]page name[/url]

But you also might want to go a little easy on the verbosity in a file name on the wiki next time... 'c2code_filter' maybe?

exonerate · 19 May 2007

thanks

i'm going to do it like that from now on.

cheers 😉

What does it take to get edit privileges for the wiki? I can view source but it won't let me change anything. I have a new oscillator to put up.

stefan · 24 Sept 2007

What SynthMaker license do you have? The WIKI authentication uses user groups, and I don't see you in any of the registered users ones. So if you have purchased a license we need to make sure you're in the right user group, which I'll leave to Malc in that case 🙂

Cheers!

We created a new user group with proper Wiki access and added you to it MackTuesday, let us know if there are any issues!

I found it inside the chorus/flanger, not sure why it's not in the toolbox.

I assume that its just an approximation of a sine, it uses less CPU than the standard sine osc anyway. 🙂

[old link] Blackviper's OS tweaking website is up, w/Vista!

exonerate wrote: Just added a cheap multi LFO, Non-Bandlimited multi LFO

I'm trying to understand "but are perfect for most uses of LFO’s" Exo; are these OK for modifying the output of a OSC, but not to be used as a tone-generating OSC themselves? Also, I'm assuming when you say "average 0.5 percent less CPU per oscillator", you mean that an OSC uses 5.0% CPU on your system, while your LFO uses 4.5%? In that case, your LFO actually uses 10% less CPU (divide, not subtract). A 0.005 difference would be hard to detect.... cheers

hmm...yeah i suppose thats not very clear, but yeah i did mean that they use 0.5 pecent less cpu, as in the SM osc's use 1 percent and mine use 0.5 percent (overall CPU usage).

I guess I'll just change it to 'uses around half the CPU of the standard oscs' or something.

oh and to answer your first question, yeah they are meant just for modulating things like your osc amplitude or filter cutoff ect... they are no good for actually generating sound (they'll alias badly) and also they don't have a phase input, so are only good as simple modulators. The idea was to create very efficient LFO's, there as basic and optimized as possible.

cheers 😉

As suggested by Infuzion, I added infos on how to build sublists in droplist primitive:

I bet you didn't know you can ZIP better than SM's ZIPper (& other file-size shrinking tips)

+ load array, & much more!

People should add their OSMs to the WIKI more as a permanant storage (if not create a tutorialor problem-fix) if others find their work useful... 😇

oddson · 12 Jan 2008

From the WIKI page: 7-zip has a better ZIP algorithm that SM does, about 5% smaller. People will appreciate a smaller .OSM when downloading your file, so do this to shrink your .OSM file while staying compatible with SM:

I disagree... the internal compression is more than adequate for most purposes. Unless theres a sample library that goes with an OSM I'd say it's not worth any extra effort.

Do I need to have the 7-zip program on my machine to read these or are they still zip files that any zip program will open?

infuzion · 12 Jan 2008

Thanks for the feed back oddson! So, I did some editing oddson wrote: From the WIKI page: 7-zip has a better ZIP algorithm that SM does, about 5% smaller. People will appreciate a smaller .OSM when downloading your file, so do this to shrink your .OSM file while staying compatible with SM:

I think SM's internal zipper is fine also.

7-zip's ZIP-Deflate routine is 100% compatible to WinXP's/SM's, while smaller, so it is useful if you can't use SM's compression (OSM too large/laggy), need to upload to a .ZIP-only host, or just want to be nice & make smaller files for others. directions

You can also (re)compress your file into a smaller .OSM while it stays automatically openable by SM.

Or use the super 7-zip routine... readable by more than just 7-zip since it is open source & other unzippers (like the popular WinRAR)add it in (but not XP by default). I use this for my personal archives of old versions.

hi,

I added in USEFUL URLS - Plugin made with SynthMaker a (hopefully) complete list of all developers of plugs in SM. I'll keep track of'em from time to time...

Acrobat · 11 Feb 2008

I added synths and effects listing beside developer websites, In USEFUL URLS -> Plugins made with SynthMaker, now you can have a quick glance at almost all the plugs ever developed in SM...

yeah, infz. it's a good idea - so diatribes of the sort can be avoided in the future.. I thought it was clear that if someone posts a file, it can be used in any-non-commercial project apart from asking the author and obtain an email with the permission, is it not so?

infuzion · 21 Feb 2008

I'm thinking of splitting up the component reference into 2 separate pages, since it is too long & takes too long to load (& likely bangs the server). Should the 1st page be alphabetical, & the second by category?[/url]

No reason, What I do is put variables in high registers starting with xmm7, and work my way down. Sometimes all the registers get used, sometimes not, they didn't get used this time.

I've actually got incredibly quick at optimizing in ASM, I have a set method now which works really well, I think I may do a little tutorial at some point to show how it's done, it's really not so hard when you know how.

I can fully optimize a block of ASM in about 10 - 20 minutes, depending on the size of the code.

What I do when I try my poor asm fu is that I start trying to get rid of as many movaps as possible and I try to rename all the xmm so that they start with xmm0 and on from there. I thought that the optimal would be that you only use xmm0 for the entire code. Maybe thats completely wrong?

Quite the opposite I guess 🙂 Maybe I should try you method, when I understand it 🙂

There's no difference between the registers xmm0 - xmm7, so use whatever makes you happy. I normally start with xmm0 and work my way up.

Martin,

It's sometimes good to use other registers so that the processor can start another instruction without having to wait for the instruction involving the xmm0 to finish.

I tend to use: xmm0 = ongoing final result xmm1-3ish = results of sub-sections/single formula xmm4-7 = (somewhat) static variables (eg: "in", 1.0...) I'll break my own rules here though 🙂

Hey that sounds sound 😀

Isnt that a bit complicated?

That's almost exactly what I do 😀

Yes that's right, you'll also notice with my code that I get nearly all the variables into registers straight away, this is so that when they are needed later in the code the processor doesn't have to wait for the memory, to perform a mulps or what ever, although I think variables can often be stored in the CPU cache memory, which would be fast but it's not guaranteed. (I don't really no much about the cache though and how it works)

So my thing is get them into registers long before you need them, seems to work pretty well.

Cheers 😉

I've done a quick tutorial taking you through the steps I used to optimize the envelope follower...Here...

I've tried to keep it as simple and to the point as possible, I don't really explain anything about SSE/ASM but hopefully it will show how to effectively optimize ASM.

If anyone needs more detail for certain bits then let me know.

Cheers 😉

Very very nice!!

one suggestion....highlight the code lines that you remove in the first step this will be more readable to users that dont know ASM .(and then you really dont need to explain nothing else)

What, giving away all my secrets!?! 😠 I mean urm, that's great that you're helping people out! 😀 I like you sharing some of your thought-process, & the comments you put in the later sweeps of the ASM.

A few tips to improve: 1) comment on what the code does: normIn = getting ABSolute value, etc... so if they see another formula that does the same thing, they know a faster ASM replacement, & teach them to think though on how the Code works. 2) How does one get the ASM dump from the Code? 2 small pics would help. 3) Sometimes as I go though the first sweep of the ASM-dump, I only comment out the extra movaps to help keep track, & add in comment-lines with the old corresponding Code-line.

Thanks for sharing!

small spelling error corrected:

the multimode delay example recites: "Save as above" 2 times I'm pretty sure the author wanted to say "Same as above" 😉

MichaelBenjamin · 21 Nov 2008

uh, yes, this asm explanation was surely needed.

so as i understood, sm generates unnecessary shuffling of data and does not use all registers to its full potential. couldnt this optimisation be automated and integrated into sm´s rendercode, so it produces faster asm on its own? its because i felt, that i when i go down to this machinecode and really do that register-variable-puzzle-game my head might explode or something similar... never thought i get any insight on this. thanks exonerate.

Well, I'm not 100% if it is SM's fault; the Code primitive might use Microsoft's Visual C++'s code-interpreting, which is not as efficient as can be. Also, Code doesn't track where each variable; it takes everything literally, forgetting what happened before it. Example: index = index + 1; index = (index<delay)&index; SM's Code will see each "index" as a unique variable. It can not see like the human brain that the 2 "index" in the second line is the same as the result of the first line.

2nd example, people often need to find a absolute value: abs = x - (x < 0 & (x+x)); But there is a very fast workaround in ASM: hex ABSMASK=7FFFFFFF; movaps xmm0,x; andps xmm0,ABSMASK;

If you guys know of a better & faster way to explain, let me know!

thanks for the tips infuzion!

Hopefully someday I can add these opcodes: + SSE2=64bit audio, SSE3=faster FFT... please

trogluddite · 2 Sept 2011

Thanks, infuzion - you must have the patience of a saint to work through typing in all the opcodes to see what comes up! Those extra jump commands look like they could be very useful for custom hopping and byoassing.
