I would like to do a synth project with a sequencer integrated but I'm facing an interogation. If for example I have a midi keyboard connected to my teensy, and I play a pattern of drum (the sounds come from samples in a sd card connected to the teensy) that I sequence and then I want to play some melody whose note are generated by a synth that is powered by the teensy (using the audio library, something like this : https://www.youtube.com/watch?v=ymccocF6hTs). My question is the following, is the teensy able to generate and superpose multiple sound?

Hope this is clear (really not sure about that sry :/)

Thank you for your answers
