HI jorge

Have been testing timer component. Nice, very nice. only a couple of questions

1.- It seems to need a DSOT 2UP and running" at least to start ( once started i coudl sellect no out put and it continue running) It's really needed?

2.- On precission. As Duration is specified in ms i assume that it has 1 ms precission, true?

3.- Can you change the input of duration to float ? the reason is. If i try to sequence something, said at 1/24th of quoarter note at 120 BPM, this is a tick every 20.833333 miliseconds. Sufficiently above 1 ms precission but, as I syncing to external BPM, i need to be as precsie as I can, so an accumulated diff of 0.83333 is suficiently representative to crash the synchronization

The minimum time a timer can accept is 10ms and I dont think it would be precise enough to use sub ms values. I think you can already do sample precise timers with poly data, I'll try to create an example soon. Green timers generating triggers at intervals less than 10 ms would just be too much for the computer to handle specially if they're flowing through the schematic and causing redraws etc.

    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.
