About memory access, my current understanding is that external memory access is much slower compared to internal one. So there is no perfect setup AFAICS. Stéphane > Le 16 avr. 2020 à 16:01, Gary Worsham a écrit : > > I just found a configuration option (under "make menuconfig") that

True, but for my own applications I'm not so interested in reverbs and am more interested in a few delay lines, as discrete echoes. So in that regard, having 2.5 seconds to use rather than 150 msec makes this a lot more usable. Ultimately I think I would have one of these boards as some sort of

I just found a configuration option (under "make menuconfig") that allows you to set the external SPI RAM to be usable by malloc(). At first glance this allows configuration of delays up to about 2.5 seconds using ef.echo(), whereas previously I could only get about 150 msec. However, 3.5
