Hi Oleg, Thanks for your watchful eye! Somehow the initial value of `u` got lost in the last commit to this function: https://github.com/grame-cncm/faustlibraries/commit/ba34ca657a8c98efc804061c5b2e1d4f7e6bc6ff. The oscillator doesn't seem to work without it. The other changes where to

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

2020-04-16 Thread Gary Worsham
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

Sorry to keep rattling on about this... #1 I realize there is no "interpolated write" possibility. #2 This isn't much different than a tape delay with wow/flutter in that there is a physical medium used for temporary storage whose speed at both write and read locations is subject to relatively

Bart, could you explain the commit 4fb8849b833629 ("Fixup quadosc") ? It looks absolutely wrong. - It removes the 1st output (cosine), why ?? - It makes the 2nd output less precise - It makes the generated C++ code worse. Oleg.
