lhello, for my m4l patch i'd like the user to choose between different distortion algorithms, each coded in gen~. i use the "gen" message to load the algorithm so the user can choose. 

i'm thinking this is a good way to save cpu load. however, does anybody know if loading gen patch dynamically can create issues in ableton  ? can it produce any kind of instability/crash ? 

another quick question with gen~, i assume that using params instead of input will also save some cpu, as params doesn't use signal ?

 save a little cpu, but it really depends on what is downstream of them before they hit audio-rate calculations. The best way to know is to profile it (see the "profiling" tab in the gen~ help patcher).  You'll also want to determine whether this has a negative effect on the sound, because param-based calculations will all act like stepped signals at the control rate. 

Often there are other ways to optimize a patch -- and again, using profiling is the best way to find out. First, try to identify what part of a patch is the most expensive, then look for ways to optimize that. 

About using the "gen" message to swap algorithms -- I'm not 100% sure whether that will work in M4L if the user doesn't have a Max license, you'd probably want to verify that first before dedicating yourself toward that path. 

i've check with a friend who didn't have a max license, swaping gen algorithms does not work without license. thanks for you answer!

I've never tried this, so it's guess work, but wouldn't using the poly~ to hold your gen patches work in this case?

i don't see why this wouldn't work, great idea!
