Synth takes too much time to load

[jofemodo]

The synth takes too much time to load. It seems that some pre-calculation is done every time the binary is executed. Do you think it would be possible to save this precalculation so we could avoid the initial precalculation? Can you give me some basic tips for doing that?

Thanks!

I think you'll want to cache results of the oscillator generation known as yc20_precalc_oscillators.
This calculation is made at runtime because its result depends on the sample rate.

I guess it's not too difficult to conserve this information in the user's .cache directory after the initial computation.

Hi, A patch for saving the precalc data would be great. It would be really nice to get a raspberry pi running this smoothly with a quick startup time! Sampo

I will do it ASAP ;-)
I'm integrating foo-yc20 in Zynthian and it should load in not more than 2-3 seconds.

OK! It's implemented and now it loads like a gunshot!! ;-)

[sampov2]

Great! So to check, is it running smoothly with the right sound on a raspberry pi 3?

Yes, but CPU load is still quite high and get some XRUNs. Some optimization would be diserable. Some ideas about reducing CPU load? ;-)
