I'm working on a project similar to Blackaddr: a guitar effects box. I'm using a Teensy 3.2, I ordered one (and an audio board) after watching the tutorial video.
I've found nearly similar threads on these forums asking about RAM and the "reverb" effect in the Audio Library. Despite reading through several times, I am still unclear whether adding a RAM chip (as suggested on the audio board page) will free more RAM to use effects like "reverb" or "chorus" etc.. From what I gleaned, the optional RAM chip doesn't actually do anything, in which case, I'm terribly confused and would love to learn why adding a RAM chip won't increase the number of blocks available to store a 1-2s reverb.
Sidenote: I tried using the audio library "reverb" effect for a delay of only 0.2s and I got the following error (which I kind of expected if I understand that it's telling me the Teensy 3.2 doesn't have enough free space to use this effect.)
