Hi @scipione205,

Thanks, but I am standing on the shoulders of giants. I completely reused the Dexed engine and took much advantage from the Teensy audio stack.

Yes and Yes. 🙂

Splitting is on my roadmap. Currently the code must be organized better… it works, but it’s not really nice. The Teensy has enough RAM to start a second engine of Dexed with an other voice - perhaps with more than 8 notes per voice…

It should not be a big problem and I would be very happy if you want to help 😄  
Current steps for this would be:

- Add a second audio queue
- Add a Mixer4 object and virtually patch both queues to the Mixer4 and the output of the Mixer4 towards the effects
- Create a second Dexed engine which uses the second queue
- Decide where to put the split point an route the MIDI messages corresponding

I hope to cleanup the code until mid February.

Regards, Holger
