The technique works with any keyboard... admittedly, the articulation stuff will vary, but isn’t essential. It’s also possible to play fast repeated strummed chords by alternating each hand on the same sound, although you won’t be able to play a six string chord (because of the spread) but will work on four string voicings.

It’s also a handy technique on a lot of other sounds that need rapid complex patterns or fast repeating chords. Think strings, brass, synths, clavinet rhythm parts, even drum and percussion!

Playing interlocked hands has always been one of the harder techniques to master on a piano. Splittable keyboards have made this so much easier!

Thanks again for your kind reviews of the song. 🎹😎🎹
