Did you click Graph-On-Parent? That would make a red rectangle that can't be deleted except by unclicking Graph-On-Parent. To get rid of the rectangle, right click on the patch, select Properties, and unclick Graph-On-Parent, unless you want to use the patch as an abstraction.

I've made some minor improvements to the code and the knobs. I've also designed slider knobs for the MIDIMix. You can download the new code and knobs using the links in the previous post.

@jamcultur it is good to see you found your source of the error. Does that tell you why? And I am curious how you found it.

Seeing the code with the error doesn't tell me why the error occurred. I found the code using the findstr command on Windows (similar to grep on Linux). I searched for the code referenced in the error message that was issued to the Pd console. Do you not get the divide by zero messages on your Pd console?

I found the code that has the divide by zero error (in blue).

@playinmyblues I have not edited any of the mimba files. I've used many other Pd patches on my Windows system without any problems, so I don't think it's anything on my system that is causing the problem. I'll try it on another Windows system when I get a chance.

@playinmyblues Yes, that is what I got when I opened main-mimba.pd, but I'm not getting that any more even though I didn't do anything to fix it. Now I'm getting this error message:

expr divide by zero detected - 'sin(w2128)sinh(ln(2)/2$f1*w2128/sin(w2128))'

@hansr @playinmyblues I'm having the problem on Windows 10 with 64GB RAM.

I just installed mimba on Windows 10, and am getting this error:

How do I fix it?
Thanks!

I wanted physical knobs, buttons, and sliders to control my Pure Data modular synth, so I got an AKAI MIDIMix. It is a reasonably priced controller with 24 knobs, 9 sliders, and 26 usable buttons. Unfortunately, AKAI did not fully document the MIDIMix's MIDI support. Fortunately, people on the Internet collaborated to reverse engineer the MIDIMix and document a communications protocol for it. I've written an object (midimix.pd) based on that document to use the MIDIMix with Pure Data. The help file (midimix-help.pd) explains how to install the MIDIMix and use it in Pure Data. You can download the files here:

BTW, I thought the MIDIMix knobs were too short, so I designed and 3D printed new ones. You can download the STL file here, if you want to print your own knobs.

@solipp Thank you!
