How to practise at 240 BPM
Treat 240 BPM as a stretch goal. Alternate between 192 BPM for clean repetitions and short bursts at 240 to get used to the speed, and keep sessions short to avoid strain. Setting the click to 120 BPM with eighth-note subdivisions gives the same grid with fewer, calmer clicks.
Half time of 240 BPM is 120 BPM; double time is 480 BPM. If 240 BPM is too fast for a passage, the speed trainer can start lower and climb to 240 automatically.
