Velocity driven overdrive

[MichaelPNolan]

The Hammond sound is based on on/off type valve/tone wheel actuators ..
Overdrive is more like an external processing so, is it going to far to think one could take velocity data and give the player some ability to change the tone using overdrive/clipping or whatever it turns out to be.

I watched a video of the Moog Subsequent37 and they put a lot of emphasis on dynamic range and ability to drive/clip and create complex harmonics in their design where the previous more trad model and the newer Subsequent model had different headroom and control over clean or dirty.

I also have ideas like ... what if somehow the velocity parameter controlled a voltage level that affected the gain of pre-amp. Why? Because I'm going to put a pre-amp for headphone playing in my next box but what if there was a way to interact with it such that if it was plugged into a mixer there was tonal variation and possible dynamic variation processing the original organ sound feeding into it?

I realize that velocity driven overdrive would make no sense because each new note might reset the level and effect other notes. However, for the sake of experimentation I still will do something, possibly for a kind of solo/lead mode.

Hm I think I guess what you have in mind. The dynamic of electrical instruments is quite challenging and harder to handle for amplifiers then produced and mastered music.
There is a little difference between the organ and organ_pro in terms of dynamic and volume. I put a bit more know how into the second variant. It's not online and actually only available via Email requests.

I played also with some simulations and there are a lot of differences.

I am not sure if it would be possible to port a valve overdrive to the ESP32. It would bring a lot of characteristics and I guess also a specific dynamic into the sound.

I sent my prototype of your Organ to a friend and they called it a great success and I wait for some videos.
So I'm happy to make the most of it until you release organ_pro. Some DSP would be good.
I have bought some Raspberry Pico microcontrollers to see how they handle the organ because I have the idea of firmware updates for people with no idea how to use an IDE and libraries to get changes. The pico seems to be a file copy easy load thing ...
I just put together a dual 7 seg that is all RGB for a kind of midi data controller feedback interface. So I'm using up about 5 pins for that on the Arduino.
