How to control Tempo and Bass with Adafruit Music Maker Shie

by ayler92 on Wed Jul 20, 2016 12:54 pm

Hi Guys!

I am looking to create a project that will allow me to use the Adafruit Music Maker Shield in order to control my musics tempo or bass line upon input from another sensor on the micro controller. Is this possible with this shield, if not do you have any suggestions?

Thanks!

Ryan

You're using the Music Maker as a midi device to generate the bass line?

What kind of sensor do you want to use for input?

Hi!

I am planning to use a hall sensor on a rotating wheel to measure its rpm. I will then convert the rpm to the linear velocity and I want the tempo or bass line of the music to change in relation to the velocity as the vehicle moves faster.

Thanks for the reply!

Can't you just adjust the time between midi key commands?

Just so I understand correctly, are you suggesting that I adjust the time between the midi key commands in relation to the changing velocity? Do you know if I am able to adjust the midi key commands on a pre recorded track in relation to my sensor input?

Thanks!

You're getting beyond my knowledge of MIDI. I thought you were generating the key commands on the fly.

I had a look at the Midi data format. It may be possible, but I wouldn't know how to do it. I don't think it's easy...
