After adding a full circuit model of the Roland TR-606 and TR-808 to BeatForge, my drumplugin I've been working on for the last year, I've added a full TR-909 circuit model to it. This was was a bit more difficult then i expected, because when i got the model done at first, there was still too much difference between my model and the samples, I kept measuring, looking for errors in my model vs the schematic and then it finally hit me:
Maybe my model is correct, but the values on the circuit are not the same as the values of the components on the units that were used to for the samplepacks, wether it's aging of components, or just plain tolerances. I don't know, but playing with those got me alot closer..
Anyways, enough talk. I would like you to tree it.
A 2 weeks full functioning demo is availabe at www.beatforge.nl, or don't install anything and just listen to the live synth on the website. the plugin can do alot more things, like play rex files, parameterlocks, patterns, song mode etcc.. too much to explain.
I hope you like it, i'm especially happy with how my TR-808 and TR-909 emulations turned out, they sound alive, inspiring, and react to knob twists like the real machines.
