Thought this was an interesting note on the iPad via the Raspberry Pi Synthesizer blog:
"I just ran up Piana - actually Polyana as she wasn't running on a Pi - on an iPad for the first time, and deliberately used my old 1st generation iPad to make sure the comparison wasn't grossly unfair, just highly unfair. And even so, the performance and in particular the low latency on the iPad is remarkable. 8 voices, only consuming around 50% of the CPU, and insanely low latency.
None of which is that surprising - iOS has been carefully engineered to allow low latency audio apps to be delivered, the iPad has I think an 800MHz A8, so should be approaching 2x faster than the Pi across the board. But really, latency this low and 8 voices, with ultra-short buffers so much more CPU overhead per packets delivered out of the synth. It creamed it.
All of which means I just need to find ways to get the Pi to live up to its promise - an 800 MHz ARM 11 should be delivering a lower latency experience than I am getting, so more digging in needs to be done, maybe into tuning the Linux up. But now I know what it should play like, and if I can get there it will be awesome, because on the iPad it is awesome."
