That depends on the compile time parameter CONFIG_PRELOAD_SAMPLES, which by default is 32768 sample points (which equals 743ms if the samples have a rate of 44.1kHz). You can change that value if you like. So for one mono sample this would be 32768 (CONFIG_PRELOAD_SAMPLES) * 2 (16 bit sample) = 64kB for a stereo sample you have to double it, thus it would be 128kB per stereo sample. For the total RAM usage of one instrument you have to check which samples are referenced by the instrument (since the sampler will only buffer the samples which are actually used by the requested instrument and ignore all unused samples) and multiply it with that value. And of course, if samples are shared among intruments, the respective samples will only be cached once.
