what do you mean with crashing? do you mean that the sound starts to click as you adjust certain parameters, or do you mean that the software reboots (i.e. crashes) when you load a file or adjust a parameter?
the granular does not have “safety features” built in. Certain combinations of parameter values will blow up the sound. It’s up to you to adjust the parameters to get the result you want. For example, if you trigger a lot of grains and have the max. nr of grains setting all the way up, then eventually you will cause clipping unless you adjust the level parameter.
If I did put safety features into the module, then you will have limitations on how you use the granular, and I preferred to give the user the maximum power and possibilities instead of making choices for the user.
If the module crashes when you load a file then post the file if you can, or at least tell me nr of channels, file size, format, sample rate and bit resolution.
