Please help, SNES echo is broken!

[sweatertheman]

I've been using Furnace to make SNES covers of songs, but today it seems like the echo is broken. If I use echo on one channel, every time I start playing the song, there's a loud crash of white noise. The more channels I use it on, the more glitchy the instruments become. Also, I can't use the echo macro in the instrument editor. If anyone knows why this is and how to fix it, help would greatly be appreciated!

It either could be:
-The way you set FIR filters
-The echo delay is too large with the amount of samples you use

In any case, I suggest providing your song file to confirm the reason.

Here's the project. I would like to note that I don't think I've set any FIR filters, and demo songs with more samples than mine have none of these issues. Thank you for the swift reply, by the way!

side note, i tried lowering the echo delay, and that helped, but didn't fix the issue. There's still a loud noise crash every time i start the song, and some instruments are still broken.

The total size of all the samples are already reaching the limits of SNES audio RAM - up to a point where echo delay should be 0 (i.e. no echo) in order to actually play properly. If you want to check RAM statistics, check window->statistics.

If you want to downsize your samples, you could do two things:
-Downsample it (by clicking resample in the sample editor) - this will lower the fidelity as a result.
-Trim it in the sample editor - only recommended if the sample is too long.
