Techno~ Crashing

September 8, 2011 | 6:58 pm

Hello!

I’m running a brand new MacBook Pro 2 GHz Intel i7 (4 GB 1333 MHz) with OSX 10.7.1 Lion.

I made this patch which drives a techno~ object and uses a lot of list processing to add semi-random ornamentation to preset melodies. The patch repeatedly crashes Max, even without DSP running. I don’t get a stack overflow message or anything. Even trying to Copy Compressed to share with you folks crashes Max, so I’ve attached the .maxpat file.

Opening with Command+Shift crashes Max, too.

This patch seems fairly straightforward. My only concern is that some sort of loop is being created between the techno~ objects and the list-processing subpatches.

Thanks in advance for your help.

Hi
I tried this – Max 5.1.8/Vista 32 – and was able to vary the melody and tempo; but the [>~ -0.5] object wasn’t triggering a bang. I manually triggered the [bang] and my debug window instantly filled up with the following: "techno – bad index"

then the patch continued to play the same repetitive melody.

I tried to change the [>~ -0.5] to [>~ 0.5] and *BANG* it crashed.

@n00b_meister:

When you got the "bad index" message, did you set the length of the techno~ with the "Beats" and "Subdivision" variables?

No, they were set at the loadbang defaults; it occurred only when i clicked the [bang] object below the [techno~] right outlet

crashes here also, and i got the bad index message after playing with the subdivision / beats variable.

also in the in the techno~ helpfile, the "noterange" message for the techno JS UI doesn’t seem to work???

There is definitely something not right with this at the moment…
