Ok, what about simple automation, inside the SM, not with the host? What if I need change some LFO freq from 10 to 1 Hz in a 15 minutes? No ADSR nor native Envelope are not suitable..

For such slow changes, I would suggest using green rather than streams - as well as saving CPU, it may make constructing the rest of your schematic simpler (for example, using arrays and text files to save custom settings). Here's something I put together using an old timer I made ages ago - it uses the system clock to work out the elapsed time in seconds, the rest is just simple maths.

Oh, good! The Elapsed Time module is sophisticated enough for me, so I just take it carefully and put in my project 😇 🙂

He he, I can't quite remember how it works myself - had to try lots of combinations of trigger order when I replaced some old SM components with newer ones! Mostly the complexity comes from working out the start trigger time if it is part way through a second, to make sure it counts properly from zero.

    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.
