I don’t want to argue further about this, but technically, yes, a sampler typically uses much more memory (both in fast-access RAM for playback as in storage for projects) than a software synth (synthesis like FM, wavetable, additive, subtractive…). Which is a different factor from the processing (DSP/CPU) requirements, which can also vary wildly depending on synthesis. And this commonly is significant design factor for developing such a specialized hardware as Electron does it. It’s not like there’s a linux-based computer inside where a memory requirement of 64MB/1GB typically would not be an issue. I know this because I worked as audio software developer close to hardware, some decades ago. It’s not totally out of whack that the Motorola chip they use (I think they still do) comes with this required memory builtin or as a cheap set which they put in all their old designs. But I doubt it. One could research this.
In any case, this could be one reason that they will start a new line of products soon, as it seems, because this old 68K-based CPU series has probably reached end of life now.
EDIT: Motorola Coldfire processors seem to be readily available, with no end in sight. But ARM will beat them in processing power by large. But they are also more complex to work with in a realtime environment with lots of peripherals, I think. Or it is hard to switch platforms with all this knowledge and experience built up in the house over the years.
