I have been using more and more the desktop to practice guitar. The basics: to have a good metronome. And I’m a fan of free stuff!
After checking several options, here you go:
– TapNTune – this is all-in-one type, with tuner and metronome. The good thing here is the beat and division capability. Excellent for Flamenco! http://jnote.org/47 – download at the end of the page
– Metronome – this one is really nice, with accelerator, timer and several options for compass. http://members.ozemail.com.au/~ronfleckner/metronome/
