Project/patcher works on some but not all computers
Hi folks,
I have a patcher that does exactly what I want it to do on my computer, and on all of my lab computers, but when I send it home with students, I find that it only works on half or their machines, even though they are all on similar Apple products. It is supposed to play a random interval, as part of a larger program where subjects rate each of 24 trials on a scale of 1 to 7. The problem is that for some students, it makes no sound......and for a few students, it was grayed out and wouldn't open.
I'm attaching just the sound-generating part in case there is anything obviously wrong that could account for this unpredictable behavior. Click on the seal to hopefully hear an interval.
Thanks for any clues!

Works on my M2 Air on OS X 26.3. All Macs should have that built-in QuickTime MIDI synth available, so nothing sticks out as immediately wrong when looking at your patch.
It may be worth having the students it doesn't work for, open up the console and document any errors?
I will do that. But I suspect that it may something that is different on some machines, because it works for about half of the class (like it worked for you), all on macs with the same version of Max. Even in my lab with 10 identical iMacs, this patcher doesn't make a sound on just one of them, and I can't figure out why. I was thinking that maybe it was something about the built in DLS synth - is it possible to inadvertently disable it, or turn its volume down?
still fighting with that ?
Hello again! Yes, I'm afraid so. I did rebuild the architecture of this one and a few of my other ones, which are all much less convoluted, and I made a VST version (although that one won't work on Windows). Trying to deploy these in the field, on random user's computers has been shaky, though, so I'm looking at it again. I might try your suggestion of an sfizz version if I can find an sfz piano sample.
That is a diabolically clever thing! I might have covered my entire screen with convoluted code, only to fail to accomplish that. I did make a version last night using sfz that works, but yours is more compact and much, much better. One sample with offsets! Thank you again.
you are welcome.
I found that more efficient too, because of a single file that needs to be sent.
but if you wanted full range keyboard, maybe sf2 compressed sample
would have been a better choice.
