Great. This knowledge allows for a very professional approach in instrument engineering. Learning a lot here. Looks like Bela system will really provide me with the necessary tools to implement what I have in mind. Thanks!

This series is really amazing! Thanks so much for all the hard work that went into this and the clear explanations. I notice there haven't been any new lectures added in a couple months. Will this series be continued to include the phase vocoder?

[@BelaPlatform]

Thanks for the kind words! We're very happy to hear that you're enjoying the series so far. We'll be resuming everything in the next few weeks and there is plenty more material to come.

[@snugglepuff33]

That's great to hear! I just ordered a Bela Mini so I can follow along.

I second Kevin's comment here. These videos are so clear and informative and well produced. Thanks so much for making these. I'm excited to buy a bela (or maybe plunge into the modular world and go straight to buying the salt) when I can allow myself to spend more cash on music gear.

As far as state machines go- when I was in school learning about microcontrollers we would use enum variables to control state quite often with switch states- are these ever used over if statements?
