FutureRetro Revolution by apolloturner
Basically a 303 clone with some added features..
I will go through the added features:
1. Extended Accent decay
2. Mod input with knob This allows you to modulate with external input.
3. Distortion. The distortion does not have a knob it reacts with amount of resonance in a very musical way.
4. Remix function. This feature will remix any sequence on the fly and has a lot of different settings.
4. Loop function. This feature allows you to loop a section of the sequences anywhere from 1 step to 15 steps on the fly
5. Sequence reverse
6. Digital effects ( delay, multiple reverbs, and chorus ) These are no the best but usable in low mix amounts.
7. External audio input
The bad parts:
Internal battery only lasts a year or so and is soldered on the main board. Mine came with a new battery holder soldered on so changing battery is very easy.
All in all, not a bad 303 type synthesizer. Some complain of build quality... I don't see that as an issue when you compare to a TT303 or the original 303 which are both plastic. The case is metal with wood sides so almost bullet proof. The circular sequencer takes some getting used to, but I can input sequences just as fast as any other machine now after owning it a while.
Soundwise, it comes very close to a TB303, but not exact.
