You cannot really "extend" the RAM of a board. You need a more clever way of loading samples. One common approach is to load only the beginning of all the samples in a table, and then whenever the sample is triggered, start by playing back the pre-loaded table, while you start reading the remaining of the file from disk with [readsf~]. Here is the code for such a solution: https://github.com/giuliomoro/dynamic-load-files-Pd

Dear list, i have a little problem with my raspberry pi.. I have built an eight-track sample player patch that runs on a raspberry pi. When the patch loads, it initially loads all the samples it finds in /home/pi/SamplePacks/SamplePack1, SamplePack2 etc.. into RAM using the standard approach: - create two tables for each sample - read data into tables with [read -resize table1 table2( Afterwards I use [soundfiler] and calculate the frequency for [phasor] and so on and so forth. The patch works when I load a total amount of 500 gb into RAM. Today I tested to load 9 GB of samples and the result (obviously) is the pi crashing. I have tested on a raspberry pi 2 and a raspberry pi 3. Both pis only have 1 GB of RAM so it's obvious that problems arise trying to load 9 GB of samples. Do you have any hints or ideas how I could solve this problem? Loading from disk while performing is not an option (I think) because of audio pops. Do you know any ways to extend the RAM of the pi? Maybe you know of some other small boards like beagle or so that have more RAM than a pi. Thank you very much!
