Hi folks,
As part of my project I took a filter tangent. 2 options came apparent the standard VA approaches which I have started but that can of worms was big and although working is still missing the diode filter gain correction.
But realising how much I loved the OBXa style filters I went looking and found the open source code for OB-XF. Since I’m trying to learn I took that as an example to try to convert and follow the steps to get it properly working in teensy.
You’ll see guards and stuff in here as I learnt the hard way letting calculation’s run wild crashed things. Claude’s documented this pretty well so hope it makes sense.
So I’d hope to get this in to the audio library if I’m honest. I’m grateful for everything that has been shared here. So here’s my starting point in trying to share. Here is the link to the source code along with a simple standalone example. All you need is a teensy and a daw and you will have a chance to play. It’s designed to work the same as all existing filters so should be a drop in. Yes the CC maps questionable
If anyone would like to have a look, provide feedback. Feel free to move some limits but do not use earphones or good speakers when doing so.
Simple example does not do it justice but good when added to polyphony and reverb it sounds pretty special
Example code
Thanks to everyone who is here or been here and left the knowledge.
