As predicted during Superbooth and elsewhere, today we're unleashing a new Researchware plug-in, RePro-Alpha.
It is an excessively CPU hungry anti-optimized monophonic synthesizer, in essence a stripped down version of the Sequential Circuits Pro-One we're currently modeling.
The research part is, we have implemented the same pretty extreme model of the CEM3320 Curtis filter chip in our vintage Pro-One using 5 different numerical methods, each costing a very different amount of CPU. We wish for you to spot the "most analogue" sounding method. By that we wish to see if it is worth spending a lot of CPU or if we could get away with something cheaper. Furthermore we wish to discuss the following questions:
- what differences do you spot between the models?
- when do these differences become audible, i.e. which settings promote these differences?
Please download the plug-in, check it out, it's free forever (but won't be updated other than to the final commercial version), try some stuff, build an opinion, take your time, discuss and vote here in this thread.
Also, we're happy to discuss further questions about RePro-1 in our company forum, we would like to concentrate on just the filter differences in this thread. I.e. if your Pro-One (or Synthex whatever uses CEM3320) sounds "utterly different", we'll be happy to request audio examples from you, but this isn't the focus of this thread.
Note: We are sorry if some of you can not run this plug-in due to CPU consumption. This isn't an indicator to the final version being CPU hungry as well, it is just a necessity for the trial - several filter algorithms are always run in parallel so that one can not spot the most accurate one by CPU hunger.
