hi Diki
i have used a wersi spectra for many years and found the controls fall easy to hand. if anything the spectra organ was easer to use the the pegasus i now use.
i love the pull out volumes on the specta and see the have the same on the pegasus wing too.
this is great for adding or removing a second voice or acc. i sure Abacus would agree how easy his keyboard is to use.
i dont think it will be harder to use as an arranger compared to say the abacus keyboard.
look forward to seeeing more in the next few months.
cheers
bill
