Coming back to sc, my old code doesn't work!

Hello everyone,

I’m coming back to supercollider after some time away. I had this really cool project I was working on, and I’m quite sure it used to work! I was really proud that I’d finally managed to set up an organized structure of nodes and configure the server to build it when booting up. But I can’t seem to get it to work now!

Full code is here: https://github.com/mciul/sc/blob/master/matrix_scale.scd

When I run this code, it appears to make all the nodes I need, but when I trigger notes via MIDI, I get errors saying the nodes don’t exist. When I look at the node tree, it’s empty. Where did everything go?

over here I tried yr code - node tree was full of stuff as expected - don’t have a MIDI kbd attached ATM but

    MIDIIn.doNoteOnAction(1, 1, 64, 64);

did play a note…

CMD-. caused the node tree to regenerate

so code looks ok …

I tried upgrading supercollider and got better results - but not consistent results.

It’s been working for a bit, but earlier I swear I had problems with the exact same code.

Is it possible that the sequencing of ServerBoot and waitForBoot is not consistent? My code seems to be assuming that the ~makeBusses function will finish executing before the waitForBoot function starts. Is there a chance that won’t be true?

In cases where you want things to happen in a certain order, I’d put everything inside .waitForBoot in the appropriate place. Here I suggest calling ~makeBusses.() close to the beginning of .waitForBoot, before the first s.sync.
