Let's try more workaround speak: The code is based on the same patents that lay the foundation of the CEM 3310, 3320 and 3340. Its fitness was verified by comparing it to real world voltages within a real world setting. For this purpose some boutique vintage synthesizers were acquired, opened, measured, played and listened to.Stollmeister wrote:So, will the Repro5 be a CEM version of the-polysynth-which-cannot-be-named-5 or will it be a SSM version? That is, will it be above (not) mentioned polysynth version 2 or 3? If it's a polyphonic Repro-1, I guess it will be CEM. I don't have a strong preference either way. I am just curious.
Now for the SSM version... we had a ball during Superbooth talking, laughing and being happy with Dave Rossum who, could we have memorized it, pretty much explained the whole SSM 2040 chip to us. He also offered to answer our questions, should we have any. Which would be helpful, because he designed that thing back then.
Between the lines, Dave recommended to not bother with his olden designs for oscillators and envelopes, giving Doug Curtis credit for improvements that may have been very beneficial for musicians around the world. Maybe we can get away with a tad more slop on tuning stability and envelope time consistency.
So yes, there is a very good chance that we will deal with emulating filters based on circuits using the "Rev. 2"-chip in our software, and possibly also within the context of Repro-1/5. However, by throwing this out here, I have no clue how much effort is involved, which translates to "neither do I know when it happens, nor if".
OTOH there's a good chance that parts of our team can be motivated to take a closer look at a synthesizer named after the feline group of animals. It's another monophonic synthesizer we're particularly fond of, which happens to come in three very different flavors. One of those flavours has a filter based upon that chip, albeit in a different configuration that we would required for Repro-5.
So... we'll see.
