I'd like to share a tool that I am using a lot lately and that is magically improving my understanding of what is 'groove'
a great deal.
It is a metronome that plays a pattern of accents which can be turned on/off in a 16 measure grid.
The idea is to play with it, then have the pattern silenced by unchecking the accented pattern for a number of measures and then activate that playback again to see of you are still where you are supposed to: on the beat.
I wrote in Max/MSP on a Mac so unfortunatly it is OS X only. If you are flying on Windows and are into Max (or know somebody that is) I'd be happy to send you the patch that I used as source.
Also note that this is total gamma-ware; not meant to be public in any way.
but if you have trouble using it please tell and I will try to help.
I am not really a programmer; but I like to make things that help me working that I cannot find elsewhere.
And also note, that the GUI is not really a beauty. I always found that it is the inner values that count;-)
please download it here: MyMetro
May it be as helpful for you as it is for me & my playing ...
