Quilcom Transformer: an additive synth, easier to program

[Spogg]

Hi all

This additive synth is easier to program sounds since it uses 6 generator modules each with a slider system to adjust relative partial amplitudes and also a graphic envelope module.

Often, with the Quilcom Adder, a preset was happy to have the same envelope for several partials. The Quilcom Transformer can achieve this quickly with a small trade-off of individual control of up to 16 partials at any ratios.
The Quilcom Transformer can do this of course with up to 6 individual partials at any ratio.

In addition each generator has a pitch envelope as does one FM and one Synth strip.

The architecture is similar to the Quilcom Adder but note that the 2 static filters are wired in parallel and there is a distortion module wired before the effects chain.

A futher benefit of the method used here is considerably lower CPU usage than the Quilcom Adder; again a trade-off in terms of tailoring sounds but well worth it I think.

I've created about 30 presets just to demonstrate possibilties and to offer as starting points.

For those not familiar with the stock modules underlying this project: If you double-right-click the draw-bar graph the graph is cleared and if you right-click the graphic envelope you get a load of options.

I do this for fun, as an intellectual challenge only, so feel free to use and abuse it as you wish.

I would very much welcome any type of feedback and any presets you may make.

Cheers

great spogg, thanks for sharing this, it sounds really good and i'm happy to get some insight in this well done synthesizer design!

just a little tip for you, if you select a module you can find a minimize toggle, with this you don't need to show all the gui and it can save you a lot of space which makes it much easier to follow the signals, its impossible for me to have a kind of overview how this thing is connected...

Thanks Nubeat and for the tip. I'm a naturally untidy person so my schematics are vile to look at. I didn't explore this option about minimizing so I will look at that in my other projects currently under way. I use a dual 24 inch monitor setup so I have acres of screen space too, which doesn't encourage compactness!

you are welcome spogg

yes, i thought about something like this, i use a 15" laptop
so my schematics normally look like that

Jeez Nubeat7 that's just SO neat and stylish! I tend to just focus on function and sound and as long as the end result is mostly orange it'll do for me!

FS is perfect for this, a little tidiness makes it just easier when it comes to searching bugs, which can get really painful in complex schematics and its also useful when you see the cpu at 100% and you need start optimizing

oh, yes i saw you like it orange

Looking good Spogg

this latest version is just hitting about 5% cpu on my machine and around 240mb of ram running inside Flowstone, that's a huge difference from the first one you posted

keep on doing!

This is pretty kick ass and I like the graphical envelopes (I'm trying to make something similar or a better version of Sytrus because they ruined it) I just don't understand which one is the modulator and which one is the carrier. Which one modulates which one ? Or how do you set the target for any modulator ?

[Spogg]

Jeez this is an old one and I don’t remember much about it now, sorry.

It's OK. It happens. At least the fsm file opens fine in the 309b2 so I should be able to figure some stuff out from the schematic. Theoretically.
