via Rhythm Studio"We are putting the finishing touches on a greatly improved TB-3 synth.
We rebuilt the TB-3 from scratch starting from the original synth schematics and circuit diagrams. We created hundreds of samples of the original TB-303 hardware along with more samples from a modified version of the x0xb0x so that we could study every nuance and characteristic of the true sound.
It starts with the oscillator signal which at first seem like a very standard saw and square wave, but while traveling down the circuitry, get transformed into very frequency dependent shapes. From there the signal enters the filter which is special resonant 4-pole design with an 18dB frequency response.
The most difficult part was calibrating the complex interactions of knob controls. For example, on accented notes, high resonance values actually soften the filter envelope while accent affects both overall amplitude and cutoff frequency. Just subtle difference in knob positions can dramatically change the sound.
The TB-3 mk. II retains the original synth code, and we have added a simple switch to change the modeling engine. This provides you the choice of which version fits your particular song.
Please note that the new TB-3 mk. II is very processor heavy and may affect performance on older devices such as the iPhone 3G and that generation. Newer devices have no problem running it. In these cases, we recommend that you use only 1 instance of the TB-3 mk. II or use the original emulation to keep performance of the app at a maximum."
