At first glance it doesn't look too exciting, but it has some nifty features:

* It has three UKnow oscillators. Suprisingly, they take up very little DSP (and sound pretty good, too). They can all be either Master sync or Slave sync. When the oscillator is set to slave, you can choose from one of the other two oscillators as the sync source. Don't worry about "sync feedback" -- it isn't possible.

* It has a little enhancing EQ built into the device -- I lightly enhanced the highs and the bass.

* It has a 2-pole filter, very sharp and crisp. It was the fattest one I could find -- I miss the Pro-One filter!

* Almost all the knobs are smooth, allowing you to do any kind of crazy modulation via an external Modular patch. Works great! Of course, to do that you'll need the Val Monitor+ module which you can download here:
http://www.planetz.com/forums/viewtopic ... 8&forum=16

* Since it's low DSP, you can get pretty high polyphony.

* Controllers 1, 7, 71, and 74 are built into the device, allowing you to do pitch modulation, main volume, resonance, and filter cutoff respectively. If you don't hear anything after selecting a preset, which may happen, try wiggling the main volume or the filter cutoff knob.

* It's free!!

Have fun!

nice synth

low dsp usage

very thanks

p.s

smooth all knobs - it is fantastic for external modulation ( im tested flexor value and step sequncer module ) GREAT

thanks Shayne

looks like a take-it-and-blow-it-away synth

Thanks Shayne! But with is this going to be your last?

Ahoy Shayne!
This I like - simple, but fulfilling to use - thanks very much.
Don't suppose there's any chance of adding a mono-legato mode for glide-tastic wickedness is there?

Shayne White · Post by **Shayne White** » Tue Dec 07, 2004 12:26 am

I'm glad you all like it! No, I wanted keep this synth as basic as possible -- no bells or whistles, for lowest DSP. There are plenty of other synths that feature legato mode.

I don't think I'll do any other synths because I think everything's been covered already! There isn't much more we can use in the SDK!!

Oh, go on, mate - it'd sound fantastic

Idea For Shayne (or for anyone will try to do):
What do you think about making a "serious" additive synth?

About "serious": Detunable harmonics, each harmo has his own amp-eg (if eg = loopable then eg := great

).
About the number of harmo: I think it's a good idea to make it user configurable (for example: from 4 to 64) due to optimize the patch.

About the filter you can put 2 multimode filter (one for each stereo channel) immediately before the out.

Some other features could be 2 separate eg and 2 LFO for the filers.

Effects are not required, because there are tons of fantastc effects available nowadays.

This makes the synth quite simple to do in my opinion.

I know that's possible to do it with modular, but the modulars aren't optimized and more difficult to program because the interface is more confused.

Some other opinions/ideas/suggeastions?

Are you really shure, you know, what you are talking about?

Well, he's kind of right, 64 sine osc + EG would be pretty confusing to edit in Modular

Few more ideas: stereo additive synth, with independent/semi-independent partials for left and right channels; group editing of some parameters (otherwise programming stuff will take forever); and how about a bit of additive + fm to drive the cats crazy

.

Haven't try UFlo yet tho

I will as soon as I can physically pry myself from that evul, evul SDK.

Pretty sure:
I've got modular1 (the one free for everyone) and if i want to do the synth I told before, I've got the following troubles:

I can use some sine oscillators (cheapest on Dsp resource) but they aren't tunable in harmonic relations in a easy way: I need to set the coarse and then finetutning to reach (for example) the 3rd harmonic. And I have to do this for each harmo. If I want to build a sound with 20 harmonics, like the 8' the 4' the 2_2/3' etc... the work is a lot.

Then I need to merge all this sources, and to do this I need a mixer, but the mixer has only 4 inputs, so returnig to the example of the 20 harmonics, i need 5+2+1 =8 mixers.

So my patch has got, at least (for the ex. of the 20 harmonics), 20 oscillators with 20 loopable egs, 8 mixers, 2 filters, 2 lfos, 2 eg and the standard midi, ins-outs, vca, esync modules... Do you imagine how the hell of cables? And the dimension on screen of the patch? It isn't very handy to program in my opinion.

Another thing: if I want a patch with only 6 harmonics, I can set the volume of the other 14 osc to 0, but my patch will be as heavy for the Dsp as the one before.
So I need a different modular for each number of harmonics I need...

About the optimization: I've made recently a very simple synth on modular 1 wich has a multimodal oscillator, 1 amp-eg and 1 Uknow filter. Each of these are controlled from both a lfo and an envelope.
Well I can do at most 4 voices and the mdl file is about 1 mb.

At the same time the miniscope is about 700 kb large, but it has 3 oscillators + noise generator + 8 lfo ecc...
And I've a polphony of 12 Voices!

I don't know the new modular versions; surely they have a lot of new and exciting modules (I'm thinking of buying the mod III for Christmas)and probably they are less Dsp hungry, but how much?

Shayne White · Post by **Shayne White** » Wed Dec 08, 2004 12:28 am

I think the DSP usage for a 64+ osc additive synth would be gigantic. You're better off with a CPU synth there.

If I'm wrong, someone correct me!!

Shayne

Edit: I just tried inserting 64 sine oscillators, plus a couple of other necessities to see how much DSP it would use. A hefty amount, but not completely unworkable (as long as you have a Scope Professional card!). Well, maybe I'll think about it...it's an interesting idea.

Don't forget to check out VirSyn's Tera synth in the meantime!

Lima, have you tried Flexor's shapers? 4SinOct and 4TriOct make 4 extra octaves for the respective waveforms, and there's other harmonic shapers are way more flexible.

Another simple trick: add an octave for a sine wave by ringmodding it.

There's little chance that these are the only ways of making more harmonics in a dsp-ecoonomic way.

This far, I think the record here at z is set by a 16 osc device, Neutron7's 16Saw (or Saw16?) modular patch. But as you read now, there's other tricks to simulate more oscillators

more info about dsp save is on http://www.adern.com Tip&Trick forum thread. ( RampDivider PhaseMod ....)

Lima · Post by **Lima** » Wed Dec 08, 2004 3:50 am

Uh, ok

Probably my idea of a great dsp-saving using the sdk is wrong.

@shayne: thanks a lot to have tried

I'll not forget to check the tera, and the k5000s of a friend

(And about an additive synth with 24 or 32 harmonics? It's still gigantic?)

@ath0mjc: no, I haven't got Flexor. Christmas is arriving, and I'm planning to buy the ModIII, the Flexor will be the next one. Or could I use Flexor without the ModII/III?

Counterparts · Post by **Counterparts** » Wed Dec 08, 2004 5:17 am

Wow! Thanks Shayne

Will check it out soon...

I do have one question - if you set one of the oscs to be a master, but synch it to another (and enable the synch button) what effect would this have (if any)?

"I think the DSP usage for a 64+ osc additive synth would be gigantic. You're better off with a CPU synth there."

strange ?? my old K2000 can manage 96 osc with 96 amp eg and 96 pitch eg without any problem .
I'm sure there is a way to optimize this well ! i do analyse /resynthese with my K2000 but it's a pain in the ass to set up the EG . I think it could be possible to do a FFT analyse and then create the EG directly from the software ( a kind of EG table ) then import this table in the plug in
then after you could tweak the eg one by one . or import two eg table and then morph between the two etc ..
so yes i miss a additive synth !!

That exactly the way Addi8, Mod III stock CWA patch that came with SFP is conceived. It is quite a rich synth considering it's limited dimensions and dsp weight.

This far, I think the record here at z is set by a 16 osc device, Neutron7's 16Saw (or Saw16?) modular patch. But as you read now, there's other tricks to simulate more oscillators

basically, 64 in BlackBox Oscillators, or actually an virtually unfinite number limited by your dsp.
plus more than 500 chords from piano, guitar and etchnic instruments.
all you have to do is to set the octave of each group of 8 oscillators (in the rack 8 for ex).
All kind of oscillators are available, from basic multi/uknow to waldorf wavetables and much more (and RD oscillators too if you wish). of course, you are not obliged to have the same oscillator on all layers : you can mix them, any of them, use phase mod or gated FM, quad morphing... and link them by groups of 3/5/8 if you wish, which are then tunable by the main oscillator slot(s) (synth or modular)...
