Here’s some helpful applications I use to practice with on the computer and different electronic devices.
Also, please check out these ideas on GuitarKitchen!
Drum Machine
Beatcraft on PC. Here are some beats that I use to practice. You can program most any software to do the same thing.
If you are on a Mac, you can use GarageBand and/or Logic. You use the percussion drummer and choose Latin Percussion.
You can use the clave, the clave and tumbao, and the clave, tumbao and cascara. I also usually put in a back beat, too. And sometimes a splash cymbal on the 1 of a 4 bar phrase – or the 4 of the last bar of the 4 bar phrase.
Metronome
Here’s an open source metronome on the PC. And I am checking out Tempo Perfect for free, you can use it on Mac as well. You can also use the metronome on Garage Band on the Mac.
On iOS, I use ProMetronome and Metronome Onyx and am about to try highly ranked Metronome Plus.
On Andriod, I use ProMetronome and Mobile Metronome.
