Sorry to say, but I don’t think it’s one of the best combinations I have heard, the performances on the Tyros and the Abacus gave a much better and coherent sound for me.

If you can find one, get a DX7 Synth, as in combination with the Spectra it was a cracker of a combination. , (Alternatively link the Spectra to a computer and use Native Instruments FM8 VST)
