A focus on compressed image formats handling:

The bitmap component loads .png - .bmp - .gif Ok. But it seems that loading a compressed format ends up in a memory usage that's the same of a non-compressed one.

JPGs and BMPs for example, occupies the same amount of Kbytes in the plugin exported.

So there's actually no advantage in loading jpgs and gif instead of BMP or PNG because the bitmap component builds anyway a full pixel image at loading stage and doesn't have a on-the-fly decompressor.

And we can have transparency on PNGs so there's no reason to use GIFs...

Anybody else noticed this? Can we have a de-compression on the fly to reduce the amount of Kbytes for a plugin?

    Open it in SynthMaker?

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
