Isla Instruments S2400: Audio Engine & Analog Outs Comparisons

Paul

"Showing the lovely differences you get in the S2400 using the difference sampling / playback engines. A rough conclusion is: if you want super old-school alias-heaven, sample AND playback using the 12bit engine. If you want to back off from this slightly, sample using the 24bit engine but playback using 12bit. In addition, you can remove aliasing using the analogue output filters or, just use these for effect.

Pad 6: Sampled: ‘Hi-Fi’ 24Bit 48Khz
Playback: ‘Hi-Fi’ 24Bit 48Khz

Pad 7: Sampled: ‘Hi-Fi’ 24Bit 48Khz
Playback: ‘Classic' 12-Bit 26Khz

Pad 8: Sampled: ‘Classic' 12-Bit 26Khz
Playback: ‘Classic' 12-Bit 26Khz

BTW, YouTube makes these comparisons less apparent; in real life, the differences are maybe 25% more obvious."
