im having problems with my left foot.. im not able to get it steady on 8ths while the rest (RF, RH, LH) are doing triplets.. any suggestions on what to do?
btw, listen to this.. here's what im tryin' to do..

Count out loud to a metronome that plays both triplets and straight 8th notes.
Start with counting the trips and count them as 12/8 = 123 456 sev89 10lev12 or count each trip as 123, 123,...while the straight 8ths are playing.
Once you are comfortable with the trips then switch on the "1" to counting the straight 8ths in 4/4 time = 1& 2& 3& 4& substituting say the "&" for saying "2", so you will count 1-2, 1-2, 1-2....
This is 3 over 2 poly rhythm which is the root of 6 over 4, 12 over 4, 6/8 over 4 polys and modulations.
You will find that the problem is not with your coordination it is with your ability to distinctivley hear and repeat the counting/rhythm which directs the limb. You have got to internalize the time, specifically the subdivisions.
Applying this to the quarter note teaches you to apply it to time signatures. Every subdivision of a quarter note can be viwed/counted as a beat in time allowing you to change time signatures on any beat.
For example: 4/4=70BPM count aloud to the click 1&2&3&4&, 123, 123456, 1&2&3&4&. the tempo never changes but the musical expression and phrasing does causing you to feel a time shift but in actuality you changed notation value from straight 8ths to half note triplets to 6/8 over 4 or 6 quarters (sextuplet in quarters)back to straight 8ths.
You simply have to train your ears to hear the subdivisions always. Easier said than done but not as hard as you thought now that I explained it.
