And here’s the explanation for the 12-bit and the 6 sec.: (from a AI—but you have to press for more details, otherwise it’ll “lie” to you):
“It’s not the number of basic oscillators or the filter, but rather the data throughput in RAM during polyphonic granular modulation and the additional load from the stereo effect processors that forced Arturia to settle for 12-bit resolution in the MiniFreak.”
If that’s the explanation, then I understand why it took a little longer. It seems the built-in hardware (2 ARM CPUs) for the sample-based playback and granular synthesis system had its own performance issues that needed to be resolved, and reducing the sample buffer to 6 seconds and 12-bit resolution was likely one step toward that solution.
