Now if I put aside SDIO throughput (which I don't know much about), it doesn't seem that surprising to be able to read 32 samples at the same time. We can already achieve 32+ linearly interpolated voices on an STM32F4 (Cortex-M4 @ 200MHz) at 48kHz, and the M7 has far better performance (300MHz, better FPU) so there should be room for better interpolation (or more polyphony).

It's usually the resampling that takes the majority of CPU cycles with sample playback. So for a given amount of CPU power you can either have tons of voices that alias like hell when you transpose the samples or a quarter of those voices with nice clean detuning of the samples. I suspect this is where they might have cut corners.<br>
<br>
Of course if you want to pitch up a Hi-hat sample and the playback module has crap resampling, then there's nothing to stop you transposing the sample in a decent audio processing package first before sticking it on the sd card. (That's what I used to do with my old Akai S01 sampler that had crappy linear interpolation, and turned hi-hat samples into rustling paper bag sounds as soon as you touched the transpose control!)<br>
